1 PART IThe Field of Pediatrics Since the late 19th century, pediatrics has been the only discipline dedi cated to all aspects of the care and well being of infants, children, and adolescents, including their healththeir physical, mental, social, and psychologic growth and developmentand their ability to achieve full potential as adults. The importance of scientific inquiry and research discovery in pediatrics and related subspecialties was cemented by the creation of the National Institute for Child Health and Development (NICHD) in 1962. As the earliest pediatricians focused on social and environmental issues that affected health (e.g., housing, sanitation, and poverty), so too are todays pediatricians (e.g., racism, poverty, and other socioenvironmental influences). In 1959 the United Nations (UN) issued the Declaration of the Rights of the Child, articulating the universal presumption that children have fundamental needs and rights. However, the United States is the only UN member that has not yet ratified these rights. The pediatricians purpose is to advance the well being of children, and thus pediatricians must be concerned with specific organ systems, genetics, and biologic processes and also with environmental, psycho social, cultural, and political influences, all of which affect the health and well being of children and their families. Pediatricians must be advocates for the individual child, their families, and communities because children cannot advocate wholly for themselves. Pediatricians must serve as advocates of all children irrespective of culture, religion, gendergender identity, sexual orientation, race or ethnicity, ability, place of birth, or geographic boundaries. The more politically, econom ically, or socially disenfranchised a population is, the greater the need for advocacy for its children and for those who support children. Youth are often the most vulnerable persons in society, and thus their needs require special attention. As boundaries between nations blur through advances in media, transportation, technology, communication, and economics, a global, rather than a national or local, perspective for the field of pediatrics becomes both a reality and a necessity. The interconnectedness of health issues across the world has achieved widespread recognition in the wake of new and emerging ill nesses, such as COVID 19, Zika, Ebola, and severe acute respiratory syndrome (SARS), as well as familiar and persistent illnesses, such as malaria, tuberculosis, HIVAIDS, and vaccine preventable illness. Additionally, health issues transcend communicable disease and are influenced by global events, such as war, ethnic wars, mass shootings, bioterrorism, the burning of the Amazon rainforest, and the growing severity of wildfires, storms, drought, and hurricanes brought about by climate change to very specific events, such as the earthquake in Haiti in 2010; the displacement of families during the Syrian refugee crisis in 20162018; the White supremacist attack on a mosque in Christchurch, New Zealand, livestreamed in 2019; and George Floyds and Breonna Taylors murders in 2020. VITAL STATISTICS ABOUT CHILDRENS HEALTH GLOBALLY From 1990 to 2020, the world population grew at an annual rate of 1 per year, down from 1.3 during the prior 20 years, to reach a popula tion of nearly 8 billion

people. The population growth rate continues to decline. The Pew Research Center projects the population to reach 10.9 billion people in 2100 with a growth rate of less than 0.1 at that time because of the fall in fertility rates. Africa is the only continental region that is predicted to continue to have strong population growth, as the 20 countries with the highest birthrates currently are all located in Africa. By 2100, the countries of India, China, and Nigeria are estimated to be the largest. In 2019, the average birthrate in the world was 17.9 births per 1,000 population, with a range from 461,000 in Niger to 6.01,000 in Monaco. The most populous countriesChina (18.5 of the world population), India (17.7), and the United States (4.3)have birth rates of 11, 18, and 11 per 1,000 population, respectively, which were all trending down from previous years. Worldwide, there are roughly 2.5 billion youth under 19 years old, which accounts for approximately one third (32) of the worlds population. The African region boasts the largest share of youth under 15 at 40 compared with 26 globally. Despite global interconnectedness, the health of children and youth varies widely between and within regions and nations, depending on several interrelated factors. These include (1) economic conditions, (2) educational, social, and cultural considerations, (3) health and social welfare infrastructure, (4) climate and geography, (5) agricultural resources and practices, which account for nutritional resources, (6) stage of industrialization and urbanization, (7) gene frequencies for certain disorders, (8) the ecology of infectious agents and their hosts, (9) social stability, and (10) political focus and stability. Although genetics, biology, and access to affordable and quality healthcare are important determinants, social and structural influences on health outcomesthe physical environment, political and economic condi tions, and social, cultural, and behavioral considerationsplay as great a role, if not greater. To ensure that the needs of children and adults worldwide were not obscured by local needs, in 2000 the international community estab lished eight Millennium Development Goals (MDGs) slated to be achieved by 2015. Although all eight MDGs affect child well being, MDG 4 was exclusively focused on children: to reduce the under 5 mortality rate (U5MR) by two thirds between 1990 and 2015. It was estimated that poor nutrition contributed to more than one third of the deaths worldwide in children 5 years old, so many of the efforts to reach this goal centered on increasing household food security. There has been significant progress toward this goal; the worldwide U5MR decreased by 60 between 1990 and 2021, from 93 deaths per 1,000 live births in 1990 to 38 in 2021. However, the World Health Orga nization (WHO) cites that between 5.2 and 5.4 million children died worldwide from preventable or treatable causes. Infants younger than 28 days account for over half the deaths, followed by children age 1 11 months, and then by children age 1 4 years old. Children in sub Saharan Africa are 9 times more likely to die before

age 5 than children in the developed areas of the world (see Fig. 3.1). School children (ages 5 9 years old) also experienced a large decline in mortality since the year 1990 related to lower prevalence of infectious diseases. The infant mortality rate globally (2023) is 27.4 deaths per 1,000 live births, with female infants having a lower rate than male infants. The child death rates in the first year of life were highest in Afghani stan (106.8), Somalia (88.0), and Central African Republic (84.2) per 1,000 live births. In the least developed countries, as classified by the UN, this rate was 45 per 1,000, and the rate was 4 per 1,000 for high income countries. The causes of infant and under 5 mortality differ greatly between developed and developing nations. The leading causes of under 5 mortality are preterm birth and birth related asphyxia trauma, pneumonia, diarrhea, and malaria (Fig. 1.1). As compared with higher resourced countries, more children less than 5 years old in lower resourced countries die from nonbirth related causes (see Fig. 3.4). In developing countries, over half of the deaths in children less than 5 years old resulted from infectious and parasitic diseases, including diarrheal disease (10 of deaths) and pneumonia (15).

In the United States, pneumonia and influenza accounted for only 2 of under 5 deaths, with only negligible contributions from diarrheal diseases and malaria (Table 1.1). Although unintentional injuries in developing countries are a proportionately less important cause of mortality than in devel oped countries, the absolute rates and contributions of these injuries to morbidity are substantially greater. In the United States, the top causes of unintentional injury include unintentional suffocation, drowning, motor vehicle collision, and fire. Other causes accounted for 5 of total mortality within this age group (Tables 1.2). Violence is a sig nificant contributor to injury related mortality in all child age groups (Tables 1.2 and 1.3). Globally (2023), the life expectancy at birth is 73.2 years old, with females at 76 years and males at 70.8 years. THE CHANGING PEDIATRIC WORLD A profound improvement in child health within industrialized nations occurred in the 20th century with the introduction of vaccines, anti biotic agents, improved hygienic practices, and attention to scientific clinical practice. Efforts to control infectious diseases were comple mented by better understanding of the role of nutrition in prevent ing illness and maintaining health. In the United States, Canada, and parts of Europe, new and continuing discoveries in these areas led to establishment of publicly funded well child clinics for low income families. Although

the timing of infectious disease control was uneven around the globe, this focus on control was accompanied by significant decreases in morbidity and mortality in all countries. Later in the 20th century, with improved control of infectious diseases through more effective prevention and treatment (including the eradica tion of polio in the Western hemisphere), pediatric medicine in indus trialized nations increasingly turned its attention to a broad spectrum of noninfectious acute and chronic conditions. These included potentially lethal conditions in addition to temporarily or permanently disabling conditions. Advances occurred in the diagnosis, care, and treatment of leukemia and other neoplasms, cystic fibrosis, sickle cell disease, diseases of the newborn infant, congenital heart disease, genetic defects, rheu matic diseases, renal diseases, and metabolic and endocrine disorders. Until the 1970s and early 1980s, children affected with sickle cell disease often died within the first 3 years of life, often from overwhelm ing sepsis caused by encapsulated bacteria. In the 1980s a multicenter study showed that early initiation of penicillin prophylaxis led to an 84 risk reduction for pneumococcal sepsis. Life expectancy for those with sickle cell disease increased when penicillin prophylaxis was initi ated early in life. The use of prophylactic penicillin became the stan dard of care, increasing the importance of early detection of sickle cell disease (which led to expanding universal newborn screening) and paving the way for advances in the chronic management of the disease, including transfusion therapy, radiographic screening for silent cere bral infarctions, hydroxyurea as a disease modifying therapy, and now, gene altering therapies. The success of penicillin prophylaxis likely led to a more rapid rate of innovation in the diagnosis and management of the disease as a result of increased life expectancy. Today 95 of indi viduals born with sickle cell disease will live to their 18th birthday, and most will survive until their fifth decade. Similarly, the treatment of acute lymphoblastic leukemia (ALL), the most common pediatric malignancy, has also shown amazing 1.39 8.14 0.58 1.69 2.40 4.86 14.94 17.8212.41 6.47 9.79 8.76 4.55 6.21 HIVAIDS Diarrheal diseases Tetanus Measles Meningitisencephalitis Malaria Acute lower respiratory infections Prematurity Birth asphyxia and birth trauma Sepsis and other infectious conditions Other communicable, perinatal and nutritional conditions Congential anomalies Other noncommunicable diseases Injuries Fig. 1.1 Global causes of death under the age of 5 years.

Cystic fibrosis has shown improvements in survival as well. In the 1960s, most children with cystic fibrosis did not live to school age. With advances in pulmonary and nutritional therapies, as well as earlier initiation of these therapies secondary to earlier identification through newborn screening, a child born with cystic fibrosis in 2010 has a projected life expectancy of 39 56 years. These major advances in the management of chronic diseases of childhood were accomplished when significant improvement occurred in the prevention and treatment of acute infectious diseases, at least in industrial countries. This allowed human and economic resources to shift toward addressing chronic disease. However, infec tious diseases continue to cause significant morbidity and mortality throughout the world. In the fall of 2021, the WHO recommended the use of the RTS,SAS01 malaria vaccine for children in areas of moderate and high levels of transmission of Plasmodium falciparum, which is the most prevalent cause of malaria in Africa. This historic declaration holds great promise for improving childrens health, as more than 250,000 African children under 5 die from malaria each year. The coronavirus disease 2019 (COVID 19) pandemic has proved to be an unremitting global health challenge that has not only affected health but also changed and influenced the socioeconomic lives of people throughout the world. THE NEW NORMAL: PANDEMICS Since COVID 19 was first reported and identified in Wuhan, China, in 2019, it has radically and fundamentally affected both the public health and global health landscapes (see Chapters 311 and 449.1). The identifica tion of COVID 19 and development of a vaccine unfolded over the course of 1 year, which was a testament to the importance and critical need for scientific research and rapid clinical implementation. We learned that children could present with or without symptoms and were important factors in community based viral transmission. Whereas many children experienced minor illnesses, others expe rienced more severe illnesses, which were related to underlying chronic conditions, such as asthma or the use of medical devices for children with special healthcare needs, and around 1 of children would go on to

develop multiinflammatory syndrome (MIS C). This condition could be lethal, but most children who received timely care improved. As of spring 2023, there were over 766 million cases and nearly 6.9 million deaths from COVID 19, and the United States had the highest number of cases and deaths throughout the world. Chil dren in the United States accounted for 6 million COVID 19posi tive cases, with 0.12.0 of children hospitalized and 0.03 leading to child deaths. Although children were less affected by COVID 19related illnesses than their adult counterparts, they experienced significant mental health and psychosocial challenges, grief, and loss.

All rights reserved. 4 Part I u The Field of Pediatrics children living through the pandemic faced unprecedented learning challenges because of widespread school closures and dependence on electronic devices and stable internet connections and widening edu cational disparities, especially for those in poverty, children of frontline workers and single parents, and those already marginalized. Addition ally, children who received nutritional support in school or received in school or in home services to support their learning andor devel opmental needs (e.g., speech therapy, specialized teaching, or other ancillary therapies) also faced disruptions. These disruptions and stress contributed to an increase in mental and emotional health burdens, such as depression, anxiety, isolation, and fear; however, these burdens were unable to be matched with a sufficient number of mental health care professionals to provide needed care. The pandemic also disproportionately affected poor families and fam ilies of color in other ways. Children in these families faced increased risk of economic hardship and instability, loss of caregivers, and other challenges. Additionally, concerns about all childrens safety and welfare continued and were highlighted, as noncustodial adults had less access and exposure to children who may have experienced physical, sexual, or emotional abuse. Finally, children with special healthcare needs expe rienced insurmountable challenges throughout the pandemic, such as not receiving essential medicines, medical supplies, and nursing or home healthcare services because of supply chain disruptions and staff ing shortages. So although children largely were spared from the illness severity, there were undoubtedly victims of the sequelae that the pan demic brought forth. Now, in partnership with parents, communities, schools, and governments, pediatricians will need to continue to advo cate for and support children to mitigate COVID 19s effects on children. THE NEW MORBIDITIES Given the advances in public health in decreasing morbidity and mor tality in infectious diseases (immunization, hygiene, antibiotics), along with technologic advances in clinical care that improved survival for many chronic illnesses, attention was given to what was described in the 1980s and 1990s as the new morbiditiesbehavioral, develop mental, psychosocial conditions, and societal inequities, which have been shown to be increasingly associated with suboptimal health out comes and quality of life. The prevention, early detection, and manage ment of these types of child health problems should be a central focus of the field of pediatrics and require an expansion in the knowledge base regarding (1) physical and environmental factors affecting behav ior, (2)

normal child behavior and development, (3) health behaviors as they pertain to child health, and (4) mild, moderate, and severe behav ioral and developmental disorders. Accomplishing this would require reconceptualizing professional training, improving clinical communi cation and interviewing skills, expanding mental health resources for children, and shifting time allocation during child health supervision visits to address these concerns. In 2001 this issue was revisited and reemphasized the need to address environmental and social aspects in addition to developmental and behavioral issues (Table 1.4). This included violence, firearms, substance use, food insecurity, and school problems, as well as poverty, unhoused (homelessness), single parent families, divorce, social media, incarceration, and childcare. Although at first glance this list seems daunting and beyond the scope of what pediatricians typically address (i.e., physical health and development), many of these behavioral, environmental, and psychosocial prob lems (which all fall under what was termed the social determinants of health but are better characterized as the social and structural influences on health) account for a large proportion of variance in health outcomes in children and youth. The role of pediatrics and the boundaries of clinical practice needed to change in order to address these salient contributors to child health and well being. Newer mod els of clinical care that rely on close collaboration and coordination with other professionals committed to child welfare (e.g., social work ers, psychologists, mental health providers, educators) were developed. As this model expanded, so did the role of the family, in particular the childs caregiver, from a passive recipient of professional services to a more equitable and inclusive partner in identifying the issues that needed to be addressed, as well as helping decide which therapeutic options had the best fit with the child, the family, and the condition. The framing of salient child health issues under the new morbid ity concept acknowledges that the influences on health are hetero geneous but interconnected. Biology, genetics, healthcare, behaviors, social conditions, and environmental influences should not be viewed as mutually exclusive determinants; they exert their influ ences through complex interactions on multiple levels. For example, epigenetic changes that result from specific social and environmental conditions illustrate the influence of context on gene expression. Studies have demonstrated that while each of these interrelated influ ences are important for optimal health, development, and well being, the greatest contributions to health outcomes occur in the behavioral, social, and environmental domainsthe social and structural influences on health. From 40 to 70 of the relative variation in certain health outcomes are caused by social and economic conditions, health behav iors, and environmental factors, as well as structural inequality in the healthcare domain. Whereas traditional medical education and clinical practice emphasized the biologic and genetic determinants of health, the recognition of the new morbidities as a focus of child healthcare provi sion reinforced the need to address social and structural influences as a key component of pediatric care, training, and research.

Since then, advances in epidemiology, physiology, and epigenetics have expanded the scope of inquiry into the effects of a broad range of health influences and provided more sophisticated explanatory models for the mechanisms that explain their effects (see Table 1.4). Racism Although racism is known as Americas Original Sin, racism and racial discrimination is a worldwide problem (see Chapter 2.1). Racism can occur at the systemicstructural, interpersonal, and internalpsychologic levels. Structural racism is the hierarchical grouping of people based on physical attributes, including skin color, which assigns value to those groups and then allocates certain resources, privileges, and power to the dominant or in group. Structural racism built on White supremacy and hegemony has been a persistent and plaguing problem for over 400 years. It is racism and racist ideology that have created and perpetuated pediatric health disparities by race (see Chapters 2 and 2.1). In the after math of the state sanctioned violence against Black people, there are calls for the end of racism, police actions, and White supremacy ideol ogy throughout the world. The field of pediatrics did not go untouched in these discussions, and numerous articles were presented about how to dismantle structural racism and equip pediatricians with the tools to do so. Importantly, pediatricians have been called to examine areas in which racism and harm are perpetuated through healthcare, through policies, practices, beliefs, and ideals. Racism along with adverse childhood expe riences are some of the pressing challenges for the modern day pediatri cian in promoting equitable health access and outcomes. The issue of racism is even more relevant by understanding that of the 73,000,000 children in the United States, 50 are nonWhite, non Hispanic (26 Hispanic, 14 Black, 5 Asian, 5 other), 20 speak a language other than English at home, and 25 are immi grants or children of immigrants. Adverse Childhood

Experiences Adverse childhood experiences (ACEs) are stressful events experi enced during childhood that can have profound health consequences both in childhood and throughout the life course into adulthood. ACEs were initially defined as abuse (physical, emotional, sexual), neglect (physical and emotional), and household challengesfamily dysfunction (parental spousal abuse, mental illness in household, household substance abuse, incarceration of household member, parental separation or divorce). Retrospective studies have shown a graded dose response effect of ACEs on future adult health of those who experience the adverse event in childhood. For example, more childhood adversity is associated with significantly increased risk in later life of ischemic heart disease, chronic obstructive pulmonary disease, liver disease, depression, obesity, and cancer. People who suffer 6 ACEs die almost 20 years earlier than those who had not experienced ACEs. Although the original conceptualization of ACEs included family level psychosocial trauma, recent attempts have been made to expand the concept to include macro level stressors, such as those encoun tered in the neighborhood and community (Table 1.5). These include witnessing violence in the community, poverty, bullying and peer victimization, peer isolation, living in unsafe neighborhoods, low neighborhood social capital, living in foster care, and experiencing dis crimination or racism. ACEs and other psychosocial traumas may influence health through a number of mechanisms. ACEs are associated with adoption of risky behaviors such as substance use and early initiation of sexual activity, which in turn may increase the risk of chronic diseases such as lung cancer, liver disease, obesity, human papillomavirus (HPV) infection and cervical cancer, chronic lung disease, and premature mortality. Childhood trauma can also disrupt neurodevelopment during critical stages of brain development and contribute to social, emotional, and cognitive impairment. Finally, ACEs can result in toxic stress and lead to the dysregulation of normal physiologic processes (see Toxic Stress and Allostatic Load later). The documentation of cumulative ACE scores has value from a population based epidemiologic perspective but has limited clinical utility. An ACE score gives no information regarding specific adver sities and traumas, nor information regarding which interventions may be required. Although ACE screening may not be the optimal approach to incorporating a trauma lens into individual clinical care, a discussion around ACEs can help the clinician to begin collabora tive communication with patients and families on the importance of psychosocial stress and adversity in health and well being in childhood and throughout the life course. Furthermore, it becomes important to understand that individuals are not merely a sum of their traumas. Although the recognition of the importance of ACEs and trauma informed care has resulted in the reframing of the question whats wrong with you to whats happened to you, this needs to be seen as a transition step toward the goal of healing centered care, which includes an emphasis not only on adver sity but also on assets (Fig. 1.2). Those assets may be external (e.g., family, community, peers, mentors) or internal (e.g., resilience, posi tive coping strategies, locus of control). In a healing centered

model of care, the evolution of the question whats wrong with you to what happened to you gets further refined to include whats right or posi tive about you. Toxic Stress and Allostatic Load The effects of stress are moderated by the intensity of the stress, the bio logic response to the stress, and the social and physical environment in which the stress is experienced. Toxic stress occurs when a child expe riences stressful events that are chronic, intense, or prolonged and are inadequately buffered by the childs social support system (most impor tantly, parents and adult caregivers). Toxic psychosocial stress influ ences physical health by producing allostatic load, or pathophysiologic dysregulation of normal regulatory systems.

The systems that can be affected through allostatic load include the neuroendocrine, cardiovascular, immune, and metabolic systems.

Chronic stress can also have effects at the genetic level. Stud ies of cellular aging have shown that chronic stress decreases telomere length, a determinant of aging on the cellular level. Epigenetic changes, including differential immune system DNA methylation, may occur after child abuse and posttraumatic stress disorder (PTSD) potentially contributing to inflammatory and immune dysregulation. Pediatrics, developmental psychology, basic sciences, and public health have contributed significant advances to the study of the behav ioral, developmental, and social influences on child health. The influ ence of psychosocial stress brought about by environmental challenges, although always acknowledged as important, has taken on a new level of salience as epidemiologists have linked its occurrence to significant morbidities throughout the life course and as basic and clinical neuro science has provided a multilevel framework for understanding how behavioral and psychosocial issues get under the skin to cause physi ologic dysfunction and dysregulation. Such a framework can also be seen as a mechanism underlying health disparities (see Chapter 2). Ecobiodevelopmental Framework An ecobiodevelopmental framework has been proposed to integrate the overlapping influences of

environmental (ecologic), biologic, and devel opmental factors into a model of health and illness. This model posits that ecology (or the social and physical environment) affects biology through physiologic disruptions and adaptations secondary to allostatic load mechanisms. The environment also influences development through life course science, which includes the effects of toxic exposures and child hood adversity on learning, cognitive, behavioral, and physical health throughout the life course. Stress induced biologic responses to adversity may negatively affect development and biologic health. Biology influences development though brain maturation and neuroplasticity, which in turn are also affected by inputs from the social and physical environment. The ecobiodevelopmental framework is consistent with the biopsychosocial model while adding a longitudinal life course developmental dimension. CHRONIC ILLNESS AND CHILDREN WITH SPECIAL HEALTHCARE NEEDS The care of children with chronic conditions has become an increasingly larger part of clinical pediatrics for both the pediatric subspecialist and the general pediatrician. Children and youth with special healthcare needs (CSHCN) are defined by the U.S. Maternal and Child Health Bureau as those who have or are at increased risk for a chronic physical, developmental, behavioral, or emotional condition and who also require health and related services of a type or amount beyond that required by children generally. According to the 20182019 National Survey of Childrens Health (NSCH), 14.1 million, or 19 of U.S. children, have a special health need. The 20092010 National Survey of Children with Special Health Care Needs (NS CSHCN) reports that almost one quarter (23) of U.S. households with children have a child with a special need. The conditions these children have are extremely heterogeneous, as shown in Table 1.6. Most of these children need specialty care in addition to primary care. In the United States, 0.40.7 of children fall into the category of highest medical complexity; these children account for 1533 of all healthcare spending for children. Children with medical complexity account for 70 of hospital readmissions. Nine of 10 CSHCN have functional difficulties in the sensory, cogni tive, movement, emotional, or behavioral domains (Table 1.7). More than 65 (7.2 million) of CSHCN have conditions that affect their daily activities, and 2.3 million families experience financial difficul ties because of their childrens special health needs. The fact that 25 of family members of CSHCN cut back work hours or stop working because of their childs special needs highlights the social and eco nomic impact of child chronic illness at both the individual and the national economic level. Pediatricians are typically the point persons in the professional care of these children and provide data and expert opinion to procure needed services and resources to the child in the clinic, home, schools, and com munity. Such demands require an efficient model of chronic care. SYSTEMS OF CARE Population Health Approach Because pediatric practice is increasingly spent working with patients and families who have chronic issues and conditions, new approaches to healthcare services delivery have been proposed. Whereas tradi tional practice models concentrate efforts toward the preventive and

therapeutic needs of those patients who present for care, a popula tion health approach to care refocuses efforts to emphasize the need to address health from a community or population level perspective, with emphasis on identifying and addressing the needs of individuals and families who do not seek regular care or whose care is episodic and suboptimal from a prevention or management standpoint. Effec tiveness of such a system improves with greater collaboration between healthcare providers and payers (insurance companies) to identify gaps in care, with data surveillance systems and electronic health records (EHRs) and with an expanded cadre of healthcare personnel such as care coordinators, nurse practitioners, physician assistants, social workers, health navigators, and community health workers.

Chapter 1 u Overview of Pediatrics 7 and quality of carebased models, if implemented correctly, may fur ther advance a population health approach to care. Medical Home The concept of the patient and familycentered medical home (PFCMH) approach to providing care is defined as a medical home that provides care that is accessible, continuous, comprehensive, family centered, coordinated, compassionate, and culturally effec tive. Patients and family members are key active participants, working with clinicians to identify priorities for and approaches to care (shared decision making; see Chapter 18). A key aspect of the PFCMH is care coordination. Care coordination addresses interrelated medi cal, social, developmental, behavioral, educational and financial needs to achieve optimal health and wellness outcomes. A care coordina tor is the point person on the team who prospectively identifies the patients and familys needs, concerns, and priorities for the healthcare visit, gathers pertinent

|
information (lab results, consultations, educa tional plans, screeningtesting results), communicates with subspecial ists, and relays all important information to the clinical team before the patientfamily visit. After a healthcare visit, the care coordinator works with the family to address any ongoing concerns, directs efforts to schedule follow up appointments and referrals, and communicates information to all necessary parties. The care coordinator typically is not a physician. The intended result of care coordination is an efficient and comprehensive interaction between the pediatric team and the family, between primary care and specialty care, between ambulatory and inpatient care teams, and between the pediatric care team and the community based supports on which the patient and family depend. Provision of care consistent with the elements of a medical home has been associated with more accurate and early diagnosis, fewer emer gency department visits and inpatient hospitalizations, lower costs, fewer unmet needs, lower out of pocket medical costs, less impact on parental employment, fewer school absences, and better patient satis faction. According to the 2016 NSCH, 43 of U.S. CSHCN and 50 of U.S. children without a SHCN received coordinated, comprehensive care within a medical home. Medical and Health Neighborhood Although the medical home concept relates to practice transforma tion specific to primary care, a broadening of this concept has been proposed along two separate dimensions. The medical neighborhood expands the medical home concept and refers to coordinated and effi cient integration between primary care pediatricians and the subspe cialists, including integrated EHRs, efficient coordinated appointment scheduling, and enhanced communication. Such a system has the potential to provide a less stressful patient and family experience and could also lead to cost reduction and a decrease in medical errors. Another expansion and modification of the medical home is the health neighborhood concept. The health neighborhood is based on the recognition of the importance of coordination with community based and nonmedical providers to address comprehensively and efficiently the social and structural influences on health. Health neighborhoods include the healthcare providers (consistent with the medical home and neighborhood) but also involve services such as early intervention pro grams, the education system, childcare, community based behavioral and mental health services, legal services, nutritional support services, and other clinical and community based services that the patient and family need to access. The health neighborhood team helps families identify the needs of the patient, assists with referrals to appropriate agencies outside the healthcare system, and coordinates care. Some nonmedical services may be co located at the medical office. Medical legal partnerships (MLPs) are collaborations between the healthcare and legal systems and embed legal aid personnel in the medical clinic. These lawyers and legal paraprofessionals can provide direct ser vices to patients and families who have legal issues that may be affecting the childs health (e.g., housing code violations, utility shutoff, food insecu rity, immigration issues, educational accommodations, guardianship). In addition to providing direct services, MLPs train healthcare personnel in the legal, social, and structural influences on health and work with

physi cians and others to advocate for policy change. Other nonmedical health neighborhood services that could be co located in the medical center include supplemental nutrition assistance programs, parenting programs, behavioral health services, and family financial counseling. Many, if not most, other services are located in the community. The health neighborhood model links families to these services and provides efficient ongoing coordination and communication. Com munity health workers or health navigators are paraprofessional team members who are community and culturally informed and serve as a coordinating link between the family, the medical home, and needed community services. Community health workers and health navigators can also provide patient and family education. Expanded care models such as these have the potential to achieve what the Institute for Healthcare Improvement calls the quadruple aim for healthcare: focusing on care (improving the patient experience with healthcare, quality care, and satisfaction), health (improving the health of populations, including emphasis on equity), provider satisfaction (joy in work), and cost (reducing per capita healthcare costs) (Fig. 1.3).

U.S. Department of Health and Human Services (DHHS) Healthy People 2030 report defines health disparity as a partic ular type of health difference that is closely linked with social, economic, andor environmental disadvantage. Health disparities adversely affect groups of people who have systematically experienced greater obstacles to health based on their racial or ethnic group; religion; socioeconomic status; gender; age; mental health; cognitive, sensory, or physical disabil ity; sexual orientation or gender identity; geographic location; or other characteristics historically linked to discrimination or exclusion. The U.S. Centers for Disease Control and Prevention (CDC) define health disparities as preventable differences in the burden of disease, injury, violence, or in opportunities to achieve optimal health experienced by socially disadvantaged racial, ethnic, and other population groups, and communities. Healthy People 2030 defines health equity as the attain ment of the highest level of health for all people. Achieving health equity requires valuing everyone equally with focused and ongoing societal efforts to address avoidable inequalities, historical and contemporary injustices, and the elimination of health and health care disparities. Health and healthcare disparities occur because of unequal distribution of resources that are inherent in societies that exhibit social stratification, which occurs in social systems that rank and categorize people into a hierarchy of unequal status and power. ROOT HISTORICAL CAUSES OF STRUCTURAL DETERMINANTS OF HEALTH AND HEALTH DISPARITIES Figure 2.1 displays a categorization of the multiple determinants of health and well being. Applying this categorization to health dis parities, conceptualizations of the root causes of health disparities emphasize the most modifiable determinants of health: the physical and social environment, psychology and health behaviors, socioeco nomic position and status, and access to and quality of healthcare (and the policies that place marginalized groups at greater risk based on these determinants). Differential access to these resources results in differences in material resources (e.g., money, education, health care) or psychosocial factors (e.g., locus of control, adaptive or risky behaviors, stress, social connectedness) that may contribute to dif ferences in health status. This section will explore several historical social and structural root contributors to health disparities (see also Chapter 2.1). Federal Policies and Economic Outcomes Redlining (19331960) A federally backed homeowner mortgage banking system, the Home owners Loan Corporation (HOLC), was created in the 1930s and graded neighborhoods on credit risk for investment and mortgage lending into four color coded levels that were outlined on city maps. The four color coded levels were based primarily on racial and ethnic demographics rather than economic factors, with the 2 most desirable codes being for more affluent White neighborhoods. Neighborhoods defined as Defi nitely Declining were marked in yellow and were older neighborhoods with mixed ethnic makeup, including lower income White residents and European immigrant residents, but no Black residents. Residents in these communities were allowed to get homeowner mortgages, but there was less overall economic development. Neighborhoods defined as Hazard ous were marked in red (hence the term redlined communities) and were where Blacks lived, including affluent Blacks. Residents in these

neigh borhoods were denied homeowner mortgages and were systematically disinvested by local, state, and federal government policies. The Federal Housing Authority (FHA), created in 1934 to be the government entity that would federally secure homeowner mortgages, created underwriting manuals for banks with rules regarding lending practices that included denying loans to Black applicants and devaluat ing properties in redlined neighborhoods. Therefore from the 1930s to 1960s, 98 of FHA homeowner mortgage loans were given to White Americans. This led to decades of residential housing segregation. Redlining was officially outlawed by the Fair Housing Act of 1968; however, the impact of redlining continues. Urban Renewal (19491974) After World War II, city officials and city planners across the United States described urban areas as slums, full of poor people and in blight. At the same time, the Great Migration (19161970) changed the racial makeup for northern cities, when millions of rural southern Black farm workers, domestic workers, laborers, and their families left the harsh Jim Crow segregated conditions of the South and migrated to northern cities seeking a better life and improved economic conditions and opportunities. The leaders in northern destination cities sought to control and contain these southern Black Americans. The federal government passed the Housing Act of 1949 to provide funding to cit ies across the country to clear and redevelop the slums (called slum clearance). City leaders and planners used the funds to revitalize their downtown areas to woo suburban Whites for shopping and entertain ment and simultaneously target redlined communities to demolish old buildings and houses and move poor Black and brown residents into public housing facilities (called housing projects). In 1956, the Eisen hower administration passed the Federal Aid Highway Act of 1956 that created the national interstate system. Redlined communities were targeted for placement of these interstate highways that displaced Black and brown residents into segregated housing projects. All of these fed eral policies led to the following consequences affecting public health: Residential housing segregation: Fifty plus years of discriminatory homeowner lending practices, real estate practices, and economic disinvestment have led to hypersegregation of neighborhoods and resources. Black and Latinx residents are more likely to live in neigh borhoods where the majority of residents have incomes below the federal poverty level, which is referred to as concentrated poverty. Residents living in formerly redlined neighborhoods have poorer Chapter 2 Child Health Disparities Lee M.

has other significant health consequences for Black and Latinx American chil dren, including living in food deserts (having few grocery stores in neighborhoods), digital deserts (lack of access to reliable high speed internet), having fewer green spaces, and few pharmacies. Economic disparities, racial wealth gap, and concentrated poverty: Federal policies during the 1930s and 1940s created the foundation for racial wealth gaps. The Social Security Administration and the Service mens Readjustment Act of 1944 (the GI Bill) were established to cre ate a middle class. The Social Security system was created to provide income to older adults. However, farmworkers and domestic workers were not included among the professionals that would pay into the So cial Security system. These occupations employed predominantly Black laborers, who did not benefit from the initial Social Security policy. The GI Bill provided former World War II military soldiers with low interest home, farm, and business loans; funds to pay for higher education; and unemployment assistance. White and Japanese American soldiers were granted the financial benefits from the GI Bill to buy homes and attend college. However, millions of Black soldiers were denied the GI Bill. First American (i.e., Indigenous Nations peoples) WWII veterans used the GI Bill to pay for a college education, but could not use the GI Bill to buy homes on reservations because reservation land was excluded from the GI Bill. Mexican American soldiers did not have full access to the benefits of the GI Bill for homeownership, but some were able to benefit from job training. Therefore millions of Black, Indigenous Nations peoples, and Mexican American WWII veterans did not re ceive all the financial and educational benefits of the GI Bill. White Americans have accumulated 10 times the wealth of Black Americans, which has transgenerational implications. Discriminatory hiring and firing practices place minoritized workers at higher risk of chronic un deremployment and unemployment. Additionally, there is an ongoing racial and gendered racial pay gap between White American men and women and men and women who are Black, Asian American, Latinx American, and Indigenous Nations peoples. In 2021, for every dollar a White American man made, Asian American women made 85 cents, Black women made 63 cents, Indigenous Nations women made 60 cents, and Latina American women made 57 cents. School segregation and educational underfunding: Public schools are funded by property taxes. In hypersegregated communities with concentrated poverty, schools are underfunded, with a 2019 study reporting a 23 billion funding gap between school districts with predominantly White students and school districts with predomi nantly Black, Latinx, and Indigenous Nations students. This fund ing gap leads to schools with less qualified teachers, less rigorous curricula, and fewer extracurricular activities. Black, Latinx, and Indigenous Nations students have overpolicing and harsher school punishment practices, as discussed further in Chapter 2.1. Schools are not teaching BIPOC students selfdiscipline; they are over punishing and criminalizing these students.

and environmental policies have contributed to unequal exposure to environmental toxins. White Americans produce the majority of greenhouse gas emissions but experience less of the negative health ef fects of such emissions such as asthma, other chronic lung disease, can cer, and cardiovascular disease. Black and Latinx American children in hypersegregated neighborhoods are also more likely to be exposed to lead poisoning compared with their White American counterparts. Lead exposure increases the risk of health problems, including anemia, attention regulation problems, and learning problems. Increased expo sure to mold and other major asthma triggers contributes to disparities in asthma outcomes among children of color and poor children. Resi dential housing segregation also places communities of color at risk for poor water quality and the health consequences. Figure 2.2 illustrates the complex relations among multileveled fac tors and health outcomes. Historical social stratification factors, such as socioeconomic status (SES), race, and gender, have profound influ ences on environmental resources available to individuals and groups, including neighborhood factors (e.g., safety, environmental toxins, grocery stores, transportation, healthy spaces), social connectedness and support, work opportunities, and family environment. Much of the differential access to these resources results from historical discrimina tion on a systematic, institutional, and interpersonal level (see Chapter 2.1). Discriminatory policies place historically subordinated groups at greater risk of poorer health outcomes and psychologic function ing, including sense of control over ones life, expectations, resiliency, negative affect, and perceptions of and response to discrimination. Environmental and psychologic context then have influence over more proximal determinants of health, including health promoting or risk promoting behaviors; access to and quality of healthcare and health education; exposure to pathogens, toxins, and carcinogens; patho physiologic responses to stress; and the resources available to support optimal child development. Psychosocial Stress and Allostatic Load An understanding of allostatic load helps explain how psychosocial stress influences disease, health outcomes, and health disparities (Fig. 2.3 and Chapter 1). Allostasis refers to the normal physiologic changes that occur when individuals experience a stressful event, including acti vation of the stress response systems, changes in levels of inflamma tory and immune mediators, cardiovascular reactivity, and metabolic and hormone activation. These are normal and adaptive responses to Social Stratification Mechanism Raceethnicity Environment Physical Social Behaviors Health promoting Risk taking Support for child development Parents Childcare Schools Stress adversity Allostatic load Health care Access Quality Exposure to toxins, pollutants, pathogens, carcinogens Disparities in child health development SES, social class Residence pattern (e.g., urban rural) Context Psychology Differential AccessExposure Fig. 2.2 Child health disparities.

an acute external stress or challenge, these systems revert to normal baseline states. However, when the stressor becomes chronic and unbuffered by social supports, dysregulation of these systems may occur, resulting in pathophysiologic alterations to these responses, such as hyperactiva tion of the allostatic systems, or burnout. Over time this dysregulation contributes to increased risk of disease and dysfunction. This patho physiologic response is called allostatic load. Allostatic load may contribute to increased incidence of chronic dis eases such as cardiovascular disease, stroke, diabetes, obesity, asthma, and depression. It is notable that these specific chronic diseases have increased prevalence in racial and ethnic minority groups because of long standing historical and current discrimination and oppression that have contributed to increased psychologic distress that in turn con tributes to allostatic load and the resultant disparities in these chronic diseases. Many of these conditions are noted to occur in adulthood, demonstrating the life course consequences of chronic psychosocial stress and adversity that begins in childhood. Figure 2.3 shows a model through which racism as a toxic psychosocial stressor gets under the skin to cause physiologic dysregulation (allostatic load), which over time leads to chronic illnesses that are known to have higher preva lence in minoritized populations (health disparities). The allostatic load model provides a pathophysiologic mechanism through which negative structural and social determinants of health contribute to health disparities. It complements other mechanisms noted in Figure 2.2, such as differential access to healthcare; increase in health risk behaviors; and increased exposure to pathogens, toxins, and other unhealthy agents. The Healthy Immigrant Paradox The Healthy Immigrant Paradox refers to the epidemiologic finding that first generation immigrants have better health than native born coun terparts regardless of age, sex, economic status, or ethnic category, but their health status declines and converges with the native born popula tion over time. Studies in the United States and Europe have found that most immigrants have better physical and psychologic health status than native born people of similar ethnicity in their receiving country. There are a variety of possible explanations for this health difference, including self selection bias among people who emigrate: being younger, more educated, and physically healthier than those in the country of origin who do not emigrate. In addition, immigrants may bring healthier cultural beliefs and practices that may contribute to better health out comes. However, the health status of immigrant populations declines in the decades after initial migration because of a variety of complex socio political and economic reasons, including denial of access to healthcare services (e.g., laws that prohibit immigrants from having access to preventive health services), having jobs with unsafe work conditions, adopting poorer health habits, and the psychologic stress of adapting to a new society (i.e., acculturation stress) (see Fig. 12.1). The Healthy Immigrant Paradox is not universal and has been called into question by some. Many studies of the Healthy Immigrant Para dox use self report of health status, which may be prone to bias. Not all first generation immigrants

demonstrate better health than their U.S. born counterparts. Immigrant health status can be influenced by country of origin factors (e.g., war, famine), health beliefs (e.g., perceiving obesity to be a sign of wealth rather than of poor health), and racialized immigration policies in the receiving country that favor immigrants from some countries over others. Many studies of the Healthy Immigrant Paradox do not include temporary immigrant workers who often do not have the same access to resources as do longer term immigrants. Approximately 18.4 million, or 25 of children in the United States under age 12 years, have at least one immigrant parent. Children of immigrant parents have better health and academic outcomes com pared with their U.S. born counterparts. For example, Latinx and Asian children who are born to immigrant parents (second generation) and those brought to the United States as children (1.5 generation) have better study habits and better academic outcomes compared with third generation U.S. born Latinx and Asian American counterparts. Behavioral health outcomes also vary among immigrant children and their U.S. born counterparts, where third generation and subsequent generation children engage in more risky health behaviors.

As a result of these targeted policies, we tend to see health disparities of people based upon racialethnic group, socioeconomic status (often operationalized through family income, sometimes using insurance status as a proxy), and residency patterns, such as urban and rural locale. Other stratification factors, such as abilitydisability status, may also contribute to health and healthcare inequality Child Health Disparities Asthma Disparities in asthma prevalence are seen by racialethnic group and SES. According to the CDCs 2019 National Health Interview Survey (NHIS) data, the national mean prevalence of asthma among chil dren (18 years old) was 7.0. Compared with the mean, the children with the highest prevalence of asthma were Black (18.0), Indigenous NationAlaskan Native (17.8), and Hispanic (12.5). Asthma preva lence for Asian American children was 8.2. There are also significant regional and SES differences in asthma prevalence, with children who live below the federal poverty level having a 14.5 prevalence. Exposure to environmental pollutants is one factor explaining these disparities in asthma prevalence. Although non Hispanic White Ameri cans consume the most goods and services that produce greenhouse gases (e.g., fine particulate matter), Black and Hispanic Americans have higher exposure to greenhouse gases that are associated with poor health outcomes, including asthma. Residential hypersegregation results in higher exposure to air pollution and other respiratory toxins for Black

and Hispanic Americans, increasing their risk of asthma. In addition, evidence shows a correlation between exposure to traffic pollutants and having fewer local pharmacies and healthcare providers. This triple jeopardy is more common with Black and Hispanic children. Obesity In 2018, the National Center for Health Statistics found that 19.3 of all U.S. children and adolescents (ages 6 17 years) have obesity (Fig. 2.4). Obesity prevalence was highest among Hispanic children (25.6) and non Hispanic Black children (24.2). The prevalence of obesity was 16.1 among non Hispanic White children and 8.7 among non Hispanic Asian children. The obesity prevalence among Indigenous NationAlaskan Native adolescents is 11.0 and among Native HawaiianPacific Islanders is 26.7. There are complex inter plays between social, environmental, and behavioral influences on health that contribute to obesity disparities in the United States. Studies have found that obesity prevalence is higher in communities with high rates of poverty and communities with a majority Black population because of lack of access to grocery stores and farmers markets (food deserts), overabundance of fast food restaurants, less access to parks and outdoor recreation areas, food marketing targeting, and higher healthy food prices. In addition, dietary patterns, access to nutri tious foods, and differing cultural norms regarding body habitus may account for some of these differences. Pregnancy Outcomes, Preterm Birth, and Infant Mortality The highest rates of infant mortality are seen in non Hispanic Black infants (Figs. 2.5 and 2.6).

For Black infants, the mortality rate was 10.8 infants per 1,000 live births. The top 5 causes of mortality (in order of frequency) among Black infants were low birthweight, congenital malformations, maternal complications, sudden infant death syndrome (SIDS), and unintended injuries. Black American infant mortality remains high compared with other popula tions, regardless of maternal education, insurance status, maternal age, and income. Chronic experiences with structural, institutional, and interper sonal racism contribute to elevated biomarkers for stress and allostatic load, which is referred to as weatheringthe accumulative effect of adversity on the health of individuals (see Chapter 2.1). Weathering of Black women has been associated with a risk of preterm birth and infant mortality. When examining the life course perspective, studies suggest that early life exposure to adversity, including systemic racism, increases the risk of poor birth outcomes (see Chapter 2.1). Having a racially concordant physician significantly reduces the risk of infant mortality by 39 among Black newborns. Infant mortality rates among Indigenous NationAlaskan Native pop ulations was 8.2 infants per 1,000 live births, with the leading causes of infant death (in order of frequency) being low birthweight, congenital malformations, and maternal complications. Asian American infants had the lowest infant mortality rates, at 3.8 infants per 1,000 live births, with the leading causes of death (in order of frequency) being congeni tal malformations, low birthweight, maternal complications, and unin tended injuries. The Asian American population was not disaggregated by country of origin, so granular details regarding this heterogenous American population were not available. Overall Hispanic infant mor tality was 4.9 infants per 1,000 live births, but mortality rates varied sig nificantly based upon country of origin from 3.8 to 5.6 per 1,000 live births. Leading causes of death among all Hispanic infants (in order of frequency) were congenital malformations, low birthweight, maternal complications, SIDS, and unintended injuries. The White American infant mortality rate was 4.6 infants per 1,000 live births, with the lead ing causes of infant mortality (in order of frequency) being congenital malformations, low birthweight, SIDS, unintended injuries, and mater nal complications (see Chapters 114 and 114.1). Infant mortality among the Native HawaiianPacific Islander pop ulation was 9.4 infants per 1,000 live births overall. Infant mortality rates varied in the Native HawaiianPacific Islander population when the data were disaggregated by country of origin from 10.1 to 22.5 per 1,000 live births. In 2017, the World Health Organization (WHO), UNICEF, and United Nations (UN) highlighted some of the social and environmental risk factors for such high infant mortality among Pacific Islanders, which include prematurity, birth complications, and severe infections (specifically, pneumonia and diarrheal illnesses).

among Native Hawaiians was 9.4 infants per 1,000 live births, and the leading causes of infant mortality were preterm birth and low birthweight, sudden unexplained infant death, congenital anomalies, infection, and injury. Many of the causes of infant mortality disparities can be mitigated through public policy, public health measures, and healthcare inter ventions that specifically target populations at highest risk, such as increased access to quality prenatal care, reducing air pollution expo sure, and improving physician training to reduce implicit bias and improve communication skills. Oral Health Significant differences exist in oral health status and in preventive oral healthcare according to raceethnicity, SES, and residency locale. The 20192020 National Survey of Childrens Health (NSCH) found the prevalence of oral health problems among children (ages 1 17 years) to be 17.7 for Hispanic Americans, 16.2 for Black Americans, 15.8 for Asian Americans, 12.1 for White Americans, and 13.2 for other non Hispanic Americans. The prevalence of oral health problems in this 2019 2020 NSCH were found to be highest among children who live in households with incomes below the federal poverty level (20.3) compared with children who live in households making 400 of the federal poverty level (8.7). 19 83 19 85 0 5 10 15 20 25 Infant deaths per 1,000 live births 19 90 19 95 20 00 20 14 20 10 Black, NH AIAN, NH Total Hispanic White, NH API, NH Fig. 2.5 Death rates among infants by race and Hispanic origin of mother, 19831991 and 19952014.

The children in the survey who did not show improvements in the prevalence of den tal caries were younger children (ages 6 8 years), poor children (both near poor and children living below the federal poverty level), and non Hispanic Black children.

caries and treat caries before further impairment ensues. Data from the 2014 Medical Expenditure Panel Survey revealed that being poor and lacking health insurance were the main reasons for not receiving preventive dental care. Hearing Care No data suggest that the prevalence of hearing loss (either congenital or acquired) is different among racialethnic or SES categories, but fol low up care after diagnosis of a hearing problem has been shown to be poorer in certain groups. Delays in diagnosis and treatment of hearing loss are found among children who lack health insurance, live farther away from diagnostic health centers, are poor, live in areas with spe cialists shortages, live in rural areas, and have primary care providers with limited experience in caring for children with hearing loss. Much of this disparity is reduced when families have access to specialists. Vision Problems The parent reported 20192020 NSCH found that vision problems were reported in 3.1 of Hispanic children, 1.2 of White children, 2.1 of Black children, 1.0 of Asian children, and 1.6 of children in other racial categories. Vision problems were more commonly reported among children who lived in households with an income that was less than the federal poverty level (3.4) compared with children living in households with an income greater than 400 of the federal poverty level (0.8). Vision problems were more commonly reported among children who did not have a medical home (2.6) compared with children with a medical home (1.0). Reports of vision problems in children also varied by insurance coverage type, with 0.9 of chil dren with private health insurance, 3.0 of children with public health insurance, 3.0 of children with both public and private health insur ance, and 4.1 among uninsured children. Immunization Disparities in immunization rates had been noted with household income status, insurance status, and residential location. In response to these socioeconomic disparities and to higher rates of measles cases in the 1980s, a number of interventions were initiated, including the cre ation of the Vaccines for Children program (VFC), which eliminated the financial barrier to immunization by providing free immunizations to at risk groups (Medicaid eligible, uninsured, Indigenous Nation Alaskan Native, or underinsured and vaccinated at a federally quali fied health center or rural health clinic). Although vaccination rates have improved, the 20182020 CDC National Immunization Survey Child study found income, geographic, and racial disparities in infant vaccination rates. Vaccination rates were lower among infants living in households with an income below the federal poverty level and infants who lacked health insurance. Vaccination rates varied widely by state and region of the United States. Although rates of initial primary vaccine series demonstrate no or decreasing disparities, other vaccination rates do show differences. Black and Hispanic adolescent females have lower human papillomavi rus (HPV) vaccination rates than do Whites. Reasons for this disparity include parental concerns about safety and providers not recommend ing the vaccine. Of interest, Black and Hispanic male adolescents have higher rates of HPV vaccine coverage than do Whites. Adolescent

Suicide In 2019, the CDC Youth Behavior Risk Surveillance System of 9th 12th graders reported suicide attempts by racial category, sex, and sexual ori entation. The highest rate of suicide attempts was among Indigenous NationsAlaskan Native teens (25.5), followed by Native Hawaiian Pacific Islanders (18.4), multiracial teens (12.9), Blacks (11.8), Latinx Americans (8.9), White Americans (7.9), and Asian Ameri cans (7.7). Suicide attempts were higher among adolescent females (11.0) than among adolescent males (6.6). Suicide attempts vary when stratified by sexual orientation status, with the highest prevalence among bisexual teens (24.5), followed by gay male teens (19.5) and heterosexual teens (6.4). Risk factors for suicide ideations and attempts include sexual assault, being bullied, substance abuse, depression, and experiences with interpersonal racial discrimination (see Chapter 40). Child Maltreatment In 2014, reports of child abuse and neglect were higher in Black (15.3 per 1,000 children), Indigenous NationAlaskan Native (13.41,000), and multiracial (10.61,000) children, compared with Hispanic (8.81,000), Pacific Islander (8.61,000), White (8.41,000), and Asian (1.71,000) chil dren. Poverty, measured at the family and at the community level, is also a significant risk factor for maltreatment. Counties with high poverty con centration had 3 times the rate of child abuse deaths than counties with the lowest concentration of poverty. Additionally, it is the criminaliza tion of poverty that increases the risk of poor people being reported for abuse and neglect compared to their more affluent counterparts. However, despite the fact that Black children are overrepresented in the child wel fare system in the United States, race itself should not be a marker for child abuse or neglect. Studies have found that Black parents are overreported for child abuse and maltreatment compared with White parents who engage in the same behavior because of historical systemic racism and implicit racial bias among those who report and caseworkers. Latinx childrens represen tation in the child welfare system varies by state and region, where they are overrepresented in some states, but underrepresented in other states. Indigenous NationAlaskan Native youth are underrepresented in the child welfare system in most states, but Alaska is the state with the highest overrepresentation of Indigenous children reported to the child welfare system. White American children are not overrepresented in the child welfare system and are often underrepresented. Behavioral Health Disparities Attention DeficitHyperactivity Disorder (ADHD) The 20192020 NSCH found the overall prevalence of ADHD among children age 3 17 years to be 8.9. White and Black children are more often diagnosed with ADHD (10.2 and 10.5, respectively) than are Hispanic children (6.9), Asian American children (2.7), and chil dren of other non Hispanic groups (8.5). Other studies have shown that both Black and Hispanic children have lower odds of having an ADHD diagnosis than White children. Children reared in homes with a household income below the federal poverty level are diagnosed more often (10.9) than those at or above the federal poverty level (8.3). Children with two or more adverse childhood experiences (ACEs) are almost 3 times as likely to be diagnosed with

|
ADHD (17.1) compared with children with no ACEs (5.8). Children without a medical home are more likely to be diagnosed with ADHD (9.7) compared with children who have a medical home (8.0). Children diagnosed with ADHD have different treatment expe riences. After being diagnosed with ADHD, White children, when compared with Black and Hispanic children, were more likely to be diagnosed with a coexisting anxiety disorder. Within the first year of treatment for ADHD, White children were most likely to be treated with medication or behavior therapy and Asian American children were the least likely to receive any type of treatment for ADHD. Depression and Anxiety Disorders According to the 2020 National Survey of Drug Use and Health, from 2004 to 2019, the reported prevalence of major depression episodes increased among all U.S. adolescents. In 2019, those with the high est reported prevalence of a major depression episode were 16 to 17 year olds (20.2), adolescent girls (23.0), adolescents of two or more races (20.9), and teens living in households with incomes above the federal poverty level (16.1). When stratifying by racial group, a major depression episode was found in 17.3 of Hispanic teens, 15.9 of White teens, 15.1 of Asian American teens, 12.2 of Indigenous NationAlaska Native teens, and Downloaded for mohamed ahmed (dr.mms2020gmail.com) at University of Southern California from ClinicalKey.com by Elsevier on April 20, 2024.

Differences in reported rates of depression based upon racial group may be the result of differences in the manifestation of depression symptoms, clinician treatment bias, and limited access to adequate mental healthcare. Autism Spectrum Disorder (ASD) Compared with White children, Black and Hispanic children are less likely to be diagnosed with ASD, and when diagnosed, are typically diag nosed at a later age and with more severe symptoms. Nonetheless, Blacks and Hispanics are typically diagnosed at a later age and with more severe symptoms. Disparities in diagnosis and timing of diagnosis are concern ing given that early diagnosis provides access to therapeutic services that are most effective when initiated early. Reasons for these disparities may include differences in cultural behavioral norms, stigma, differences in parental knowledge of typical and atypical child development, poorer access to quality healthcare, and differences in the quality of provider patient communication along with trust in providers. Recent CDC data suggest that racial and ethnic disparities in ASD diagnosis are decreasing. Behavioral or Conduct Problems According to the 20112012 NSCH, Black children age 2 17 years have higher rates of oppositional defiant disorder (ODD) or conduct disorder than do White and Hispanic children. Evidence suggests that the overdiagnosis of Black children with these disorders is linked to the pervasive criminalization and adultification of Black child behavior. Adults often view Black children as older, less innocent, and in less need of protection than same age peers of other racial groups. In fact,

studies have found that physicians with negative implicit racial bias are more likely to overpathologize Black child behavior and overdiagnose Black children with ODD, conduct disorder, and ADHD. The patholo gizing of Black child behavior can have severe consequences, including excessive school punishment, school expulsion, and early contact with the legal system. Developmental Delay The 20192020 NSCH found that Black children age 3 17 years had higher reported rates of developmental delay (7.4) than Hispanic chil dren (5.3), White children (5.4), and other non Hispanic children (5.4). Children living in households with incomes below the federal poverty level were more likely to be diagnosed with a developmental delay (8.7) than children living in households with an income at 400 of the federal poverty level (3.6). Children experiencing two or more ACEs have a higher prevalence of developmental delay than do children with no ACEs (10.8 vs 3.8). ACEs increase the childs allostatic load and impede neurologic development, thus placing them at increased risk of developmental delays. Evidence also suggests that physicians with negative implicit racial biases are less likely to ask Black parents and parents who speak English less fluently about their concerns regard ing developmental delays and are less likely to refer the children to early intervention, and these children are less likely to receive appropriate developmental evaluations by early intervention providers. Flourishing In the 20192020 NSCH, parents reported rates of flourishing, which is overall good mental health in their children and teens. Flourishing was measured by three behaviors: learning, resilience, and self regulation. Overall, 63.3 of parents reported their child met all three flourish ing criteria. Females (66.8) were reported as having higher flourish ing than males (59.9). The highest level of flourishing was reported among Asian American youth (73.0), followed by White (64.8), other non Hispanic children (62.1), Black (61.8), and Hispanic (59.7). Flourishing rates were lowest among youth who live in house holds with incomes lower than the federal poverty level (55.6) and highest among youth living in families with incomes higher than 400 of the federal poverty level (70.0). Child Healthcare Disparities In almost all areas, Black, Hispanic, and Indigenous NationAlaskan Native children have been identified as having worse access to needed healthcare, including receipt of any type of medical care within the past 12 months, well child or preventive visits, delay in care, having an unmet need because of healthcare cost, lack of care in a medical home, problems accessing specialist care when needed, lack of pre ventive dental care, vision screening, mental health counseling, and recommendations for adolescent immunizations (see Table 2.2). In addition, many of these healthcare indicators are found to be worse for children living in poverty and for those living in a rural area. Dispari ties in access to and quality of healthcare among children of color and poor children are linked to long standing structural barriers, systemic racist policies and practices, environmental policies, social and struc tural determinants of health, and healthcare provider negative implicit racial biases that influence

healthcare delivery and patient physician communication and relationships. APPROACHES TO ERADICATING DISPARITIES: INTERVENTIONS An example of a successful intervention that closed the disparity gap is the implementation of the VFC program, which significantly decreased the disparity in immunization rates noted among racialethnic groups and poorunderinsured children. This is an example of a public health policy approach to intervention. Interventions need to occur at the clinical level as well. The almost universal use of electronic health records (EHRs) provides a unique opportunity for collecting vital clinical and demographic data that can be helpful in identifying disparities and monitoring the success of interventions. All EHR platforms should use a standardized approach to gathering information on patient raceethnicity, SES, primary lan guage preferences, and health literacy. The Institute of Medicines 2009 report Race, Ethnicity, and Language Data: Standardization for Health Care Quality Improvement provides best practices information about capturing these data in the health record. The advancing science of clinical quality improvement can also provide a framework for identifying clinical strategies to reduce dis parities in care. Use of PDSA (Plan Do Study Act) cycles targeting specific clinical issues where health disparities exist can result in prac tice transformation and help reduce differential outcomes. Another practice level intervention that has the potential to reduce disparities in care and outcomes is the medical home model, provid ing care that is accessible, family centered, continuous, comprehensive, compassionate, coordinated, and culturally effective. The use of care coordinators and using community based health navigators are effec tive tools in helping to break down the multiple social and health sys tem barriers that contribute to disparities. Community engagement is an essential requirement for lessening health and healthcare inequities. Health systems, practices, provid ers, public health, researchers, and payers need to include community voice and representation in all aspects of quality improvement, data interpretation, program design and development, and dissemination. To do less would be working on people instead of working with peo ple. To use a phrase from the disability advocacy community: Nothing about us without us. Many potential interventions seem appropriate and demonstrate efficacy under ideal circumstances. However, if the intervention does not address the concerns of the end userspatients and communitiesor fit the social or cultural context, it will likely be ineffective in the real world. Only by involving the community from the beginning, including defining the issues and problems, can the like lihood of success be optimized. At the provider level, there are opportunities for training in implicit bias and communication skills, as discussed in Chapter 2.1. Shared decision making has been found to improve physician patient rela tionships and health outcomes. Another strategy to address cognitive biases in physician clinical decision making is to identify heuristic and other cognitive errors (see Tables 5.3 5.5) and use the diagnos tic time out (see Table 5.6) when a diagnosis does not fit the clinical presentation. Population health strategies have the advantage of address ing the determinants of disparities at both the clinic and commu nity levels.

Health disparities are a consequence of social and structural deter minants of health that often have developed based on historically rac ist policies and other practices and traditions that led to the social stratification mechanisms inherent in many modern societies. Health disparities mirror other societal disparities in education, policing, employment opportunities, and living conditions. While society grap ples with the broader issues contributing to disparities, healthcare and public health can work to understand the multiple causes of these dis parities and develop interventions that address the structural, clinical, and social root causes of these inequities. Visit Elsevier eBooks at eBooks.Health.Elsevier.com for Bibliography. 2.1 Racism and Child Health Mary T. Bassett, Zinzi D. Bailey, and Aletha Maybank RACISM AS A SOCIAL DETERMINANT OF HEALTH AND HEALTH INEQUITIES An emerging body of evidence supports the role of racism in a range of adverse physical, behavioral, developmental, and mental health out comes. Racialethnic inequity in health outcomes in the United States is long standing, apparent from the first collection of vital statistics in the colonial period. However, the extensive data that document racial disparities have not settled the question of why groups of people, par ticularly of African and Indigenous Nations peoples ancestry, face increased odds of shorter lives and poorer health (see Tables 2.1, 2.2, and 2.3). The role of societal factors is well recognized in determining population health, but often omits racism among social determinants of health. This oversight occurs in the face of a long history of racial and ethnic subjugation in the United States that has been justified both explicitly and implicitly by racism. From the early 18th century, colonial America established racial categories that enshrined White supremacy, conferring rights specifically on White men, while deny ing these rights to others. This racial designation was social and not based on genetics. Similar, perhaps less explicit, discrimination has continued through the centuries and remains a primary contributor to racialethnic inequities in childrens health. Current lifelong exposure to interpersonal, structural, and institutional racial discrimination and subordination has a significant impact on Black health outcomes. For generations, racialethnic disparities have been documented beginning at birth and extending across life. In 2018, life expectancy at birth for Blacks was almost 4 years shorter than life expectancy of non Hispanic Whites, influenced heavily by disparities starting at birth (Table 2.3). The infant mortality rate (IMR), arguably the most important measure of national health, has shown a

persistent Black White gap despite a substantial decline in U.S. IMR for all racialeth nic groups (see Fig. 2.5). NCHS data in 2022 showed a double digit IMR only among non Hispanic Blacks, with 10.38 deaths per 1,000 live births, compared to 4.41,000 for non Hispanic Whites. A troubling stagnation in IMR, with no recent decline, is found among Alaska Natives and Indigenous Nations peoples. The 2022 IMR among non Hispanic Indigenous Nation peoples or Alaskan Native individuals, 7.68 deaths1,000 live births, has remained essentially unchanged for almost 2 decades. Exposures that affect infant survival occur before birth. Much of the maternal and child health literature emphasizes a higher preva lence of maternal obesity, diabetes, and substancealcohol use before conception among Black women as individualized risk factors leading to disparities in birth outcomes (Chapter 114.1). A California study of maternal obesity found that 22.3 of pregnant Black women and 20.3 of Latina women had a body mass index (BMI) of 30 40, com pared with 14.9 of White and 5.6 of Asian women. BMI 40 was more than twice as prevalent in Black (5.7) than in White (2.6) women. Further, in a nationally representative study of over 7 million singleton live births from the 2016 and 2017 U.S. National Vital Sta tistics System, although maternal prepregnancy obesity was associated with the risk of preterm birth in the general population, risk varied by maternal age and raceethnicity. Maternal obesity among non Hispanic Black women was inversely associated with risk of preterm birth among those younger than 30 years, but positively associated among those age 30 and older. Similar relationships were shown for non Hispanic White and Hispanic women. Although individual risk factors such as obesity contribute to differences in birth and health out comes, individual risk factors alone do not sufficiently explain these differences. Further, a focus on individual risk factors may contribute to a narrative that places blame on the individual without acknowledg ing the structural and social conditions of patients lives influencing the prevalence of these risk factors. Proximal factors such as maternal obesity do not capture the root causes of early childhood health inequi ties, social determinants of health, which present intervention points for achieving health equity. Achieving health equity requires examining equity in outcomes and also equity in process. Causes and interventions to address health ineq uities can be conceptualized as occurring upstream, downstream, or somewhere in between (Fig. 2.7). Downstream determinants occur on individual levels, including individual biology and specific risk factors and behaviors. In Figure 2.7, measures of health and health inequities, like life expectancy, IMR, maternal obesity, and maternal age, are at the far right and are considered downstream factors. Clinical inter ventions focused on downstream factors may help individuals, but do not address factors upstream that drive inequities in population health outcomes. These upstream factors include the physical, social, work, and service environments in which people are born, grow, live, work, and age that lead to downstream outcomes. If a child lives in

public housing that is systematically underresourced to eliminate common pests, that child is more likely to encounter asthma triggers, experience asthma attacks, and require emergency department care or hospitalization. Interven tions could include remediating one apartment or home or increasing access to insurance; however, this is not getting at systematic mecha nisms by which public housing becomes a social determinant of health. Moreover, these interventions do not address the reasons that families need public housing in the first place or why these living conditions are more prevalent among certain communities compared with others. The distribution of these living conditions is patterned by institu tional inequities in the public and private sectors and in our laws and regulations, which represent a wider set of forces and systems shap ing the conditions of daily life. Social inequities, like racism, sexism, classism, heterosexism, and ableism, represent upstream social deter minants of health that affect access to resources and healthy living con ditions and are inequitably distributed across preexisting hierarchies of power. Resource allocation for public housing and the absence of universal access to a living wage might drive the living conditions within public housing. Focusing solely on downstream results of larger inequitable structures seldom yields sustainable change and ignores the roots of health inequities while tending to blame individuals structur ally constrained by centuries of inequitable systems. Prenatal maternal exposures to pesticides, lead, and other envi ronmental toxins vary by race. This inequitable distribution is largely driven by racist policies and practices affecting exposures to small and large scale environmental hazards (see Chapter 2). The effects of per sistent racism are stressful and toxic to the body, with the experience of discrimination across leading to biologic changes that persist the life span, especially for pregnant women and their children. Thus racism is an essential social determinant of racialethnic inequities in mater nal and child health. Racism can increase cortisol levels and lead to a cascade of effects, including impaired cell function, altered fat metabo lism, increased blood glucose and blood pressure, and decreased bone formation (see Chapter 1 and Fig. 2.3).

In New York City, White women had lower rates of adverse birth outcomes: 1.3 had preeclampsia, less than half the rate for Black women (2.9).

These findings reinforce the critical role the physician has in explicitly asking families about potential exposures to racialized stressors and trauma. The increased risk of disease for populations of color continues from infancy into childhood (see Table 2.1); racialethnic dispari ties are seen across almost all health indicators, with most relative gaps remaining stagnant or worsening over the past two decades. Compared with White children, Black children are about twice as likely to be diagnosed with asthma, more likely to be hospitalized for its treatment, and more likely to have fatal attacks. The Black White disparity in asthma has grown steadily over time. Indigenous Nations children and youth (19 years) also experience negative health outcomes, with the highest rates of unintentional injury and mortality rates at least twice as high as for other racialethnic groups. Additionally, according to a 2017 NCHS brief, Latino youth age 2 19 have the highest rates of obesity in the 2000 CDC sex age specific growth charts. The NCHS data show that 25.8 of Latino (followed by Black) children qualified as obese from 2015 to 2016. Black children are more likely to be exposed to witnessed, personal, or family violence (an example of an adverse childhood experi ence), and exposure to these stressful life experiences is associated with academic, behavioral, and health problems. Notably, children with more stressful life experiences have a higher likelihood of experiencing ear infections, acute respiratory infections, obesity, eczema, viral infections, and teen pregnancy. EXPLAINING RACIAL DISPARITIES: A TAXONOMY OF RACISM Explanations of these ubiquitous racial gaps have focused on indi vidual factors, including variation in individual genetic constitu tion, behavioral risks, poverty, and access to (and use of) healthcare services. Scientists agree that race is a social construct that is not based on biology, despite the persistence of the idea that racial cat egories reflect a racially distinctive genetic makeup that has a bearing on health. In fact, the genetic variation between individuals within a particular racialethnic group is far greater than the variability between races. Further, biologic ancestry is distinct and separate from the social construct of race. Despite the genetic data, many groups have been racialized over time. Notably, the U.S. Census Bureaus demographic classifications reflect this process. In the mid to late 1800s the census counted mulattos,

those of White and Black ancestry, as another race. Starting in the late 19th century, Eastern European immigrants and Jews were considered different races. As early as 1961, the U.S. Census identified Mexicans and Puerto Ricans as White even as racial classification varied by geography. All states collected birth records by 1919, but there was little uniformity on how race was col lected, if at all, across states. It was not until 1989, when the National Center for Health Statistics (NCHS) recommended assigning infant race as that of the mother and that standard guidance and categories were issued for states on collecting racial data at birth. Existing categories were changed and continue to change based on the economic, cultural, or political utility of the time, rather than actual genetic distinction. Defining Racism Racism has consistently structured U.S. society and is based on White supremacy, a hierarchical idea that Whites, the dominant group, are intrinsically superior to other groups who are not classi fied as White No single definition of racism exists, but one useful description is racial prejudice backed by power and resources.

do not capture how broader shared social experiences shape outcomes. Racial domination or racism contributes to varia tion in the populations access to resources and exposure to disease and to the group experience of fair treatment and opportunity. Although many groups in the United States may encounter discrim ination based on raceethnicity, most of the modest literature on health effects of racism has focused on people of African descent, leaving a need to better understand the impact of racism on people of color. Table 2.4 and Figure 2.3 describe various pathways through which racism affects health. Although the empirical data on disparities for non Black popula tions of color deserve greater research, useful frameworks exist to understand the disparities that public health has documented to date. A useful taxonomy of how racism operates in society has four catego ries: internalized racism, interpersonal racism, institutional racism, and structural racism. Each is relevant in considering the impact of racism on child health. Internalized Racism When the larger society characterizes marginalized racialized groups as inferior, these negative assessments may be accepted by members of those groups themselves, either consciously or uncon sciously. The result is devaluation of personal abilities and intrinsic worth, in addition to the capacity, of others also classified as being a part of a marginalized racialized group. The best known docu mentation of internalized racism comes from the study of Kenneth and Mamie Clark known as the doll experiment, conducted in the 1940s. Black children, both males and females, were asked to choose between a Black doll and a White doll according to attributes described by the interviewer. In response to positive attributes (e.g., pretty, good, smart), most children chose the White doll. The Clarks interpreted this finding to mean that Black children had internal ized the societal views of Black inferiority and White superiority, even at the expense of their personal self image. Repeated by a New York City high school student several decades later, the findings were much the same, with 15 of 21 children endorsing positive attri butes to light skinned dolls. Multiple studies confirm that racial identity is established in young children, both Black and White, along with negative views of blackness. Developmentally, however, youth of color often explore racial identity earlier than their White counterparts. In terms of health outcomes, depending on perceived inferiority or superiority of the group, racial identification is associ ated with self esteem, mastery, and depressive symptoms. Low self esteem is independently implicated in mental health disorders and may contribute to the phenomenon of stereotype threat, in which personal expectation of underperformance correlates with prevailing social stereotypes and adversely affects actual performance. Interpersonal Racism How racial beliefs affect interactions between individuals has been the most studied aspect of racism. Interpersonal racism refers to situations where one person from societys privileged racial group acts in a discriminatory manner that adversely affects another per son or group of people. Such actions may be based on explicit beliefs or on implicit beliefs of which

the perpetrating individual is not consciously aware. The experience of unfair and prejudicial treat ment has biologic consequences, reflected in measurable increases in stress responses. Such effects of interpersonal racism are best documented for mental health, where perceived unfair treatment serves as psycho social stressors, and are less robust for physical health outcomes. A 2021 study of 10,354 U.S. children age 10 and 11 years found only 2.8 of Whites, 5.4 of Latinos, 6.2 of Asian and Pacific Islanders, 6.5 of Indigenous Nations peoples, and 10 of Blacks self reported enduring racial discrimination. Furthermore, dis criminatory experiences have been strongly and consistently linked to greater risk for anxiety, depression, conduct disorder, psycho logic distress, ADHD, ODD, low self esteem or self worth, and challenges to psychologic adaptation and adjustment (see Chap ter 2). Perceived racial discrimination can affect behavioral, men tal, and physical health outcomes and is associated with increased alcohol and drug use among Indigenous Nations peoples (age 9 16 years), increased tobacco smoking for Black youth (11 19 years), higher depressive symptoms among Puerto Rican children, and insulin resistance among young females. Understanding the enduring impact of childhood experience on adult health has increased with the study of ACEs (see Chapter 1). ACEs have well documented cumulative negative health effects that occur across the life span and are patterned by raceethnicity. Early experience of racism is a proxy measure for toxic stress. The ques tion, Was childs name ever treated or judged unfairly because of their race or ethnic group? is included in the U.S. Census Bureaus NSCH, a random sample of over 90,000 households to assess the Table 2.4 Pathways Between Racism and Health and Examples Economic injustice and social deprivation Residential, educational, and occupational segregation to lower quality neighborhoods, schools, and jobs (both historical de jure discrimination and contemporary de facto discrimination) Lower salary for same work Lower promotion rate despite comparable evaluations Environmental and occupational health inequities Placement of bus garages and toxic waste sites Selective government failure to prevent lead in drinking water (per Flint, Michigan, 20152016) Disproportionate exposure of workers of color to occupational hazards Psychosocial trauma Interpersonal racial discrimination, including microaggressions Exposure to racist media, including social media Targeted marketing of health harming substances Legal: cigarettes; sugar sweetened beverages Illegal: heroin; illicit opioids Inadequate healthcare Inadequate access to health insurance and healthcare facilities Inadequate treatment caused by implicit or explicit racial bias State sanctioned violence and alienation from property and traditional lands Police violence Forced urban renewal (use of eminent domain to force relocation of urban communities of color) Genocide and forced removal of Native Americans Political exclusion Voter restrictions (e.g., for ex felons, ID requirements) Maladaptive coping behaviors Increased tobacco and alcohol consumption Stereotype threat Stigma of inferiority leading to physiologic arousal Impaired patient provider relationship Small, often unintentional racial slightsinsults (e.g., a judge asking a Black defense attorney, Can you wait outside until your attorney gets here?)

Children of color from low income households, especially Latino children, were reported to have the lowest level of health. However, higher SES did not pro tect children exposed to racism from experiencing relatively poorer health. Children exposed to racism were also more likely (by 3.2) to have a diagnosis of ADHD and were 2 times more likely to expe rience anxiety and depression. Toxic stress increases cortisol levels in the body, increasing the risk of chronic disease. One study revealed that adolescents who reported average or high levels of perceived discrimination experienced exag gerated cortisol output in response to negative affect, whereas those reporting low levels of perceived discrimination did not experience significant reactivity to negative affect, after controlling for other stressors. Adolescents who experience racism with no support have been shown to have higher levels of blood pressure and obesity than those with emotional support, which can be protective. Medical practice has not been exempted from occurrences of interpersonal racism. Using variation in adherence to established clinical standards in diagnostic and treatment decisions across racialized groups, researchers have been assessing interpersonal racism in physician patient interactions. The most comprehensive review of such bias in clinical care remains the study by the U.S. Institute of Medicine, in which the discriminatory treatment was inferred from examination of clinical decision making rather than from directly observed interactions. For virtually every condition studied, Black patients were less likely to receive recommended care. Such racial bias has been most extensively established in adults but also extends to children. A study conducted in an emergency department found pediatric patients (21 years) were less likely to receive medically indicated pain medication if they were Black, mirroring the historical misconception of reduced pain sensitivity among Blacks. Within this context, it is unsurprising that perceived interpersonal racism has been linked to healthcare use, includ ing delays in seeking care or filling prescriptions and distrust of the health system. When Black patients receive concordant care from Black healthcare providers, their communications, health outcomes, and care are improved when compared with care from White providers. Perceived and experienced discrimination can be measured by at least six instruments (scales). Questions such as Are you treated with less respect or courtesy than other people, Do people act as if they are afraid of you, Do people act as if they think you are not smart, and Do you receive poorer service than other people, can be quantified with responses that range from Almost everyday to Never.

would persist because of institutional and structural racism. Broadly, institutional racism refers to patterns of discrimination based on policy, culture, or practice and carried out by state and nonstate institutions (e.g., corporations, universi ties, legal systems, cultural institutions) within various sectors (e.g., housing, education, criminal justice). Key to current residential segregation are banking practices dating to the post Depression era. As an institution, the education system has been another tragic case of how racism affects childrens health. In addition, mass incarcera tion by the criminal justice system has dramatically increased in the United States while remaining relatively flat in other developed countries (Fig. 2.8). Over a lifetime, approximately 30 of Black men have been imprisoned. In school, children of color can experience not only individual racism but also institutional racism, as documented by higher rates of disciplinary actions such as suspensions, and at younger ages than White children. According to a 2016 U.S. Department of Edu cation civil rights survey, Black children, who represent only 19 of national preschool students, account for a staggering 47 of out of school suspensions. Black preschoolers are 3.6 times more likely to be suspended than their White peers. Black females, representing 20 of the female preschool population, account for 54 of out of school suspensions. Many schools have a zero tolerance policy for childhood behaviors, which criminalizes minor school infractions. Unfortunately, this disparity persists as children continue through the school system: for kindergarten to grade 12 (K 12) students, Black children are 3.8 times more likely to face out of school suspension than White peers. This inequity is particularly harmful because the educational system feeds into the criminal jus tice system (school to prison pipeline). Black students are 2.2 times more likely to have either school related arrests or law enforcement referrals than their White peers. The U.S. Department of Education survey also reveals racial inequities among children with disabili ties. For K 12 children with disabilities covered under the Individu als with Disability Education Act, 21 of multiracial females were issued at least one out of school suspension, compared with 5 of White females. Racial disparities in school discipline for minor infractions, dis ruptive behavior, or disobedience is linked to the concept of adulti fication. In this harmful, often unrecognized racial bias and social stereotype, adults and especially police view Black children (as young as 510 year) as older, less innocent, and more culpable than White students of the same age. Black male children are perceived as older, bigger, and more physically threatening than White peers. Black female children are viewed with similar characteristics plus a perception that Black female youth need less nurturing or protection, are more inde pendent, and less innocent. In addition to the threat to educational and employment prospects, school suspensions also affect childrens health. A 2016 brief from the Yale Child Study Center states that early suspensions and expulsions of children harm behavioral and social emotional development, weaken ing a childs overall development. Furthermore, these forms of punish

Chapter 2 u Child Health Disparities 21 Institutional racism can function without apparent individual involvement and has powerful repercussions that persist centuries later. Both medical professional organizations and educational institu tions have legacies of racial discrimination rooted in scientific racism. In 2008 the American Medical Association (AMA) issued a formal apology for its long history, dating to the 1870s, of endorsing explicitly racist practices, including exclusion of Black physicians, silence on civil rights, and refusal to make any public statement on federally sponsored hospital segregation. In 2020, the American Academy of Pediatrics (AAP) board of directors published an acknowledgement and apol ogy, Truth, Reconciliation, and Transformation: Continuing on the Path for Equity, for the institutionalized racist and exclusionary treatment of two Black physicians, Drs. Alonzo deGrate Smith and Roland Boyd Scott, dating back to 1939 and spanning until 1945 when they were finally admitted to the AAP as the first Black members. Exclusion from medical associations also meant exclusion from gaining privileges to work at the majority of hospitals. Despite a focus on medical school desegregation in the 1960s and 1970s, the presence of Black students in medical schools is actually declining. Low enrollment has become especially critical for Black men, who in 2014 accounted for about 500 of the 20,000 medical students nationwide. If physicians hold stereo typed views about race that affect their clinical decision making, the declining diversity of medical student bodies may well have conse quences for the quality of medical care. This history of institutional racism on people of color contributes to the mistrust, apprehension, and fear projected toward the entire medical establishment. Structural Racism The institutional racism within medical institutions reinforces insti tutional racism in other sectors, creating a larger system of discrimi nation, structural racism. Structural racism can be described as the totality of ways in which societies foster racial discrimination via mutu ally reinforcing systems of housing, education, employment, earnings, benefits, credit, media, healthcare, and criminal justice. These patterns and practices in turn reinforce discriminatory beliefs, values, and dis tribution of resources, which together affect risk of adverse health out comes. Institutional racism and structural racism are sometimes used interchangeably, but structural racism refers to overarching patterns beyond a single institution, or even a collection of

institutions. Histori cally, government policies and practices have been largely responsible for the creation of these structures. De facto and de jure urban residential segregation serves as a case study for how the mechanisms of structural racism operate across mul tiple sectors and can affect child health and development across the life course. As described in Chapter 2 urban residential racial segregation was reinforced by the practice of redlining initiated by the U.S. Fed eral Housing Administration in 1934. This now illegal (but still covert) practice demarcated urban neighborhoods to be made ineligible for home loans based primarily on the racial composition of the neigh borhood. Thus Black neighborhoods were excluded from the feder ally financed, post Depression home ownership boom and remained segregated. Through this segregation, existing resources were system atically removed (disinvestment) and led to further impoverished com munities of color. The effects of residential segregation were not restricted to the bank ing or housing sectors. Residential segregation ties together multiple systems, driving childrens access to and quality of healthcare, educa tion, and justice, as follows: Residential segregation and the healthcare system. Healthcare insti tutions were explicitly racially segregated by law and inequitably resourced until passage of the 1964 Civil Rights Act. Vestiges of this segregation continue in hospital level segregation and racial com position by hospital. In addition, institutions that provide mainly for uninsured or underserved residents are often financially unsta ble, leading to higher risk of closure in disinvested neighborhoods of color. On the provider level, fewer primary care and specialty physicians practice in disinvested, segregated neighborhoods, and those who are present are less likely to participate in Medicaid. Residential segregation and the education system. Schools have a similar history of racial segregation and, after a brief respite of inte gration peaking in 1980, the level of segregation now resembles pre civil rights levels. School segregation is related to high risk health behaviors. Within these schools and in their neighborhoods, Black children experience disproportionate penalization and criminaliza tion in the educational and criminal justice systems, reinforcing in stitutional racism in other sectors and other forms of racism. A low income Black child is much more likely than a low income White child to live in a segregated neighborhood. The result is that the Black child will face not only the cumulative disadvantage in both family and neighborhood resources and experiences over time but also the initiation of chains of disadvantage during sensitive periods of childhood key for development and adult transition (e.g., early childhood, adolescence). Residential segregation and the criminal justice system. Incarceration is concentrated in overpoliced and criminalized Black communities. In the NCHS, almost 13 of Black children had a parent impris oned during their childhood (to age 17 years), compared with about 6 of White children.

risk of childrens antisocial behavior. Most notably, experiences directly related to institutional and struc tural racism, operating through residential segregation (including financial hardship, parental imprisonment, and neighborhood vio lence), result in higher levels of ACEs for Blacks and Latinos than for Whites. There has been growing, consistent evidence of the lifelong association between ACEs and a range of negative physical and mental health outcomes across the life course. Structural racism, shown here with the example of residential seg regation, affects child health through various direct and indirect, over lapping pathways, including the concentration of dilapidated housing, inferior quality of the social and built environment, exposure to pol lutants and toxins, limited access to high quality primary and second ary education, few well paying jobs, overpolicing and criminalization, adverse experiences, and limited access to quality healthcare. OPPORTUNITIES TO ADDRESS RACISM Racism as a determinant of health has strong empirical support, and there is promising evidence for community wide approaches to its mit igation. Less is known about effective interventions in clinical settings. Most medical schools and subsequent training will not have prepared practitioners to examine the role of racism in their patients lives or clinical care settings. Nonetheless, it is reasonable to expect that pedia tricians can help address racism and promote racial justice in at least three ways: during individual patient encounters and at their practice sites, as members of institutions that provide medical care and training, and as respected community members. Clinical Settings A first step in understanding that racism affects everyone is personally assessing implicit bias. Such biases reflect reflexive patterns of think ing, often using racial stereotypes stemming from living in a racially stratified society. The Project Implicit Race Implicit Association Test (https:implicit.harvard.eduimplicittakeatest.html) is available online, and its results are confidential. The purpose of such tests is to create awareness, not apportion blame. Nonetheless, results are usu ally jarring for all participants, no matter their racial identity, many of whom will uncover negative racial biases of which they were unaware. Such individual assessments may contribute to addressing interper sonal racism as it triggers self reflection. Further, a growing number of organizations offer training in understanding common behaviors associated with implicit bias, including microaggressions (see later) Downloaded for mohamed ahmed (dr.mms2020gmail.com) at University of Southern California from ClinicalKey.com by Elsevier on April 20, 2024.

pedagogy or acquired by a pediatrician in training or clinical practice. Such an approach emphasizes respect for the expertise that caregiv ers bring to raising their child and begins with the presumption that caregivers want to do what is best for the child. By doing this, physi cians can form a collaborative relationship, rather than one based on racial stereotypes and blame. Cultural competence is a widespread concept, recognizing that other cultures exist that the dominant culture must learn to decode. In contrast, the concept of cultural humility, for which training is increasingly available, considers equality among cultures and a partnership approach to differences. During clinical encounters with children and families, healthcare workers can use their authority to acknowledge racism. Although there is still a gap in evidence on how, when, and what, pediatricians can consider having The Talk with their patients who are Black, young adolescent, and male. The Talk is the conversation that Black parents typically initiate with their children regarding interactions with police. In doing so, the pediatrician affirms the need for such conversations to promote safety and may provide opportunities to connect families to community resources. For all young children and youth of color, pediatricians should ask patients if they have they been treated unfairly because of their race, recognizing this can be a form of bullying. The experience of racism at all levels can be traumatic. Trauma consists of experiences or situations that are emotionally painful and distressing and that overwhelm peoples ability to cope, leaving them powerless. Pediatricians must consider adopting trauma informed care practices that shift the paradigm from, What is wrong with you? to What has happened to you? In addition, healthcare providers must strive for structural com petency, which is the trained ability to discern how a host of issues defined clinically as symptoms, attitudes, or diseases also represent the downstream implications of a number of upstream decisions, accord ing to Johnathan M. Metzl and Helena Hansen. Consequently, it is helpful to ensure that clinical practices are aware of other social ser vices that may enhance health and engagement with clinical care, such as a need for legal counsel to address substandard housing, counter landlord harassment, or negotiate threatened evictions (http:medical legalpartnership.org), or the support of literacy by prescribing or distributing childrens books in order to encourage parents to read to children (http:www.reachoutandread.org). Institutional Settings The healthcare institution more broadly is also a setting where racial dynamics occur. Introducing conversations about race may uncover experiences that would not otherwise be apparent. A common out come of implicit racial bias is microaggressions, actions and attitudes that may seem trivial or unimportant to the perpetrators but create a cumulative burden for those who perceive them. A physician of color might be asked for identification on entering a hospital, whereas White colleagues are not so queried. These microaggressions occur in interac tions among staff and with patients and may contribute to an unspoken and uncomfortable racial climate. Although such interactions rarely would violate federal

discrimination standards, interaction between coworkers shapes an entire practice and can be perceived by families. Encouraging institutions to assess the impact of race among patients and staff is a first step. Healthcare delivery institutional set tings can use both data and patient accounts to examine racial effects in the practice and experience by routinely disaggregating assessment measures by raceethnicity. Patient reported satisfaction or quality of care might be disaggregated by race. In addition, it is important to consider racial equity within the practices employment structure: Are there discrepancies in hiring, retention, and salaries by race? Are there proper supervision and grievance procedures, particularly around issues related to racial microaggressions? Also, consider the images and language used to discuss and represent both patients and staff, par ticularly when alluding to raceethnicity. Organizations such as Race Forward (https:www.raceforward.org) and organizational assessment tools developed by the Race Matters Institute can help guide institu tional assessments and internal change processes. Several local health departments have already incorporated antiracism training into staff professional development and introduced internal reforms to drive orga nizational change. Because institutional reform is closely associated with other models of productive practices, including quality improvement, collective impact, community engagement, and community mobiliza tion, application of an antiracism lens should be judged by its contribu tions to organizational effectiveness and on its moral merits. Education or training institutions have a special role in ensuring a workforce that is both diverse and informed. Patterns of student admis sions should be scrutinized, as should the curriculum. The recruitment of Black healthcare workers will enhance the benefits of racially con cordant care between Black providers and patients. Although many medical schools now include diversity training and provide instruction on cultural competency, such instruction is often brief (and sometimes delivered online). By contrast, approaches based on structural competency, cultural humility (see Chapter 12), and cultural safety have been implemented in health profession als training in such countries as Canada and New Zealand. These approaches emphasize the value of gaining knowledge about struc tural racism, internalized scripts of racial superiority and inferiority, and the cultural and power contexts of health professionals and their patients or clients. Health professionals benefit from the scholarship of diverse disciplines about the origins and perpetuation of, and rem edies to counter, racism. Finding class time for these topics encounters a biomedical bias that is widespread in medical education, although arguably successful medical practice also requires a host of skills in addition to a firm grounding in pathophysiology and recommended treatments. Racism results in damaging disparities that cause ill health and shorten lives, which justifies the teaching hours committed to its understanding. Pediatricians as Advocates for Antiracist Practices and Systems Physicians are respected members of communities and wield the power, privilege, and responsibility for dismantling structural racism. A conceptual review of structural racism highlights the promise of place based interventions that target geographically defined commu nities, to engage residents and a range of institutions (across sectors) in order to ensure equitable access to resources

and services, remediating the processes set in motion decades earlier. Clinicians play a role in advocating with the halls of medicine in linking patients to services, programming, and other resources and advocating for responsiveness in addressing gaps. Over time, concentrated efforts across sectors in targeted areas have shown improvement in a host of social outcomes, including health outcomes. Similarly, providing access to higher quality housing, either with housing vouchers or housing lotteries, had unexpected positive health impacts. These findings are encouraging, as are the social policy interventions and systemic change, including legislation such as the Civil Rights Act, the advent of Medicare and Medicaid, and tenement regulations, associated with the narrowing of racial gaps.

Chapter 3 u Global Child Health 23 GLOBAL BURDEN AND TRENDS IN CHILD HEALTH The under 5 mortality rate (U5MR), also known as the child mor tality rate, serves as a reliable gauge of child well being. It measures the outcome of a countrys health system and reflects a nations social and economic development. The global U5MR fell by 61 between the years 1990 and 2020. Despite these gains, in 2019 an estimated 5.3 million children under 5 years of age died worldwide, which is equivalent to 37.1 deaths per 1,000 live births, or nearly 13,700 child deaths each day. The burden of the worlds child mor tality disproportionately falls upon low and middle income popu lations of Africa and Asia (Fig. 3.1), with 82 of all child deaths in the world occurring in just two regions: sub Saharan Africa (55) and South Asia (27), compared to the less than 1 of child deaths occurring in high income countries (HICs). Consequently, a child born in sub Saharan Africa is over 15 times more likely to die by age 5 years compared to a child born in an HIC. Improvements in child mortality have been uneven globally, regionally, and nationally. Significant disparities in child mortal ity persist and are concentrated in specific regions of Africa and Asia. The countries with the highest child mortality gap between the richest and the poorest in 2019 were Nigeria, Guinea, and the Central African Republic. In Nigeria in 2019 while the national rate of child mortality was 117 deaths per 1,000 live births, at the sub national level, the rates ranged from 58 to 261 deaths per 1,000 live births. Although the number of child deaths has decreased dramatically over the past 3 decades, the early years of life remain one of a childs most vulnerable periods. Among the under 5 child deaths, nearly half occurred within their first month of life (2.4 million deaths in 2019). This estimate of neonatal deaths (1 month of age) trans lates into 17.9 per 1,000 live births. Declines in neonatal mortality occurred at

slower rates, so that in 2019 the neonatal deaths made up 48 of all under 5 deaths (Fig. 3.2). Neonatal deaths account for a smaller percentage of child mor tality in low and middle income countries (LMICs) compared to HICs (Fig. 3.3), but the absolute risk of death remains significantly higher. A child in sub Saharan Africa or in Southern Asia is nine times more likely to die in the first month of life than a child born in an HIC. An estimated 2 million stillborn deaths (28 completed weeks gestation) burden families worldwide every year, which correlates to 13.9 deaths per 1,000 births.

These figures are likely an underestimate because stillbirths are underreported, reflecting the low prioritization of this vulnerable age group. Before 2006, no organization published global, regional, or country specific stillbirth rates. Progress to reduce stillbirths has been slow, with the annual rate of reduction estimated to be half that for neona tal deaths between 2000 and 2019. Almost all stillbirths occur in LMICs (98), with three quarters in sub Saharan Africa and South Asia. Most childhood deaths are caused by conditions that could be prevented or

managed through improved access to simple, low cost interventions. The most common causes of child death are pre term birth complications, intrapartum related events, pneumonia, and diarrhea (Fig. 3.4). Of all under 5 child deaths, 2.61 million were the result of infectious diseases and 21.7 of all child deaths were vaccine preventable. Neonatal disorders accounted for an estimated 46 of the deaths in children younger than the age of 5 years. In contrast, child deaths from infections in developed coun tries are less common, where injuries and congenital malformations account for higher proportions of under 5 deaths. Undernutrition, including fetal growth restriction, stunting and wasting, and micro nutrient deficiencies, contributes up to 45 of under 5 deaths and poor childhood development in LMICs. Undernutrition has an enormous impact on child mortality because of the vicious cycle between nutrition and infection whereby lowered immunity and mucosal damage from inadequate dietary intake lead to increased susceptibility to pathogen invasion, while recurrent illnesses impair the childs appetite and ability to absorb adequate calories and nutri ents. In addition, undernutrition early in life can have long lasting consequences, including impaired cognitive ability and reduced school and work performance. Infants who start out life with a low birthweight are at high risk of death, contributing 6080 of all neonatal deaths.

Chapter 3 u Global Child Health 25 infants are premature (born before 37 weeks of pregnancy) or suf fered from fetal growth restriction. About half of stillbirths take place during labor, ranging from 10 in developed regions to 59.3 in South Asia, which reflects the role that timely, high quality care around delivery can play to prevent many deaths. Mortality among older children age 5 14 is low compared with the younger cohort, although 1 million children in this age group died in 2016, which is equivalent to 3,000 children dying every day. Infectious diseases play a smaller role in deaths among these older children, with injuries from causes such as drowning and road traffic trauma account ing for more than a quarter of the deaths and noncommunicable dis eases for about another quarter. Child health should not be assessed based on mortality rates alone. Children surviving illness are often left with lifelong disabilities, burdening their families and affecting their economic productivity. Approximately 1 in 10 children are born with or acquire a disability, and 80 of these disabled children live in LMICs. Neonatal disor ders, infectious diseases, protein energy and micronutrient deficien cies, hemoglobinopathies, and injuries are leading causes of disability in children. Child deaths can also lead to disability in the surviving mother. For example, a woman who has a stillbirth is at risk of an obstetric fistula or death, with an estimated 7898 of women with obstetric fistula having had a stillbirth. Also, perinatal loss and child death is a psychologic trauma. Stillbirth, neonatal death, and child loss can lead to posttraumatic stress disorder, depression, anxiety, guilt, and in some settings shame and social stigma, particularly in the mother, with significant impact on the health and well being of the family. Adolescents age 10 19 years who have benefited from the gains in child survival grow up to find themselves in social settings where less attention and fewer

|
resources are devoted to their well being compared to their earlier years of growth. The paucity of support during this time of transition into adulthood diminishes the impact that child survival can have on their lives. Adolescents made up 18 of the worlds population, approximately 1.8 billion individuals, in 2010, and the adolescent population is expected to increase to over 2 billion in the year 2050. The vast majority of adolescents, 88, live in LMICs. In 2050, sub Saharan Africa is projected to have more adolescents than any other region. Although adolescent mortality rates are far lower than their younger age cohorts, in low income countries adolescents face a lack of educational and employment opportunities and increased risk of injuries and violence, HIV and AIDS, mental health problems, adolescent marriage, and teenage pregnancypreventing them from attaining their potential as they transition into adulthood. The decade of adolescence is a critical period when poverty and inequity frequently transfer to the next generation. The intergenerational transmission of poverty is most apparent among undereducated adolescent females. In many parts of the world poor teenage females are likely to be married early, risk ing premature childbearing, higher rates of maternal mortality, and contributing to infant and child undernutrition. THE SOCIAL DETERMINANTS OF CHILD HEALTH AND THE COVID 19 PANDEMIC The gross national income level accounts for much of the differences in child mortality rates observed between countries; however, other sig nificant factors affect child health. For example, although the wealth of the United States places it in the 7th position with respect to gross domestic product (GDP) per capita (2022) in the world, the U.S. child mortality rate is ranked 47th in the world, at 6.5 deaths out of 1,000 live births, which is higher than Cuba (5.1), Canada (4.9), the UK (4.3), the Czech Republic (3.2), and Japan (2.5). In addition, national estimates of mortality mask differences in health status among subpopulations within the same country. In Burkina Faso, the child mortality rate is 43.7 per 1,000 live births among children born to mothers with no education, whereas it is 16.7 per 1,000 among children born to mothers with at least secondary education. Similarly, in 2016 the child mortality rate in Bolivia was 18.6 per 1,000 live births for children in the highest wealth quintile, whereas it was 55.1 per 1,000 for children living in the lowest quintile. Child health is influenced by socioeconomic factors that operate at multiple levels of society. Disparities in these socioeconomic fac tors translate into child health inequities as reflected by high rates of disease, poor nutrition, and disability. The immediate, underlying, and basic structural determinants of disease, malnutrition, and dis ability are outlined in Figure 3.5. Preventive and curative medical interventions focus on the immediate causes of poor health; how ever, inequities in child mortality and morbidity will persist unless the basic and underlying determinants of health are addressed. Socioeconomic and Political Roots of Disparities in Global Health The root influences on a childs health often lie

in the economic and political environments in which the child is born (see Figs. 3.4 and 3.5). Growth of economies during the first half of the 20th century was associated with dramatic health improvements, with falling mortality rates and rising life expectancy across all regions. However, the second half of the 20th century was characterized by growing disparities in global economies and health between and within many countries. According to the World Inequality Report (http:wir2018.wid.world) between 1980 and 2016 the rich est 1 of the world reaped twice as much of the worlds income as the poorest 50 of the world (27 of income growth compared with 12). Although almost all countries report population level income inequalities, a few such as the United States have seen income disparities at historical proportions. For example, since 1980 the bottom half of Americans captured only 3 of the total growth. Growing income inequalities translate into greater differ ences in health outcomes, such as life expectancy, between the rich and poor in the United States (Fig. 3.6).

All rights reserved. 26 Part I u The Field of Pediatrics universal access to education and health care contribute to Europes significantly lower levels of income disparities. Evidence supports the notion that inequalities are not just a human rights issue, but are detrimental to economic growth. Wealthier households spend a smaller percentage of their own income, thereby dampening demand and slowing down econo mies. Poorer households face greater challenges to invest in health and educational opportunities, translating into less human capital and obstacles to be productive and contribute to the economy. In extreme cases, inequalities can threaten social unrest, which further undermines economic activity. Global disparities have grown between many wealthy and low income countries, in large part because of austerity measures, includ ing structural adjustment programs, imposed on many postcolonial countries by the International Monetary Fund (IMF) and World Bank. To receive loans and pay off their debt, many of these countries were required to take on austerity measures that transformed their economies to produce cash crops and export natural resources to HICs, rather than supporting local industries and investing in human capital and social services. The focus on cash economies rather than health and social service systems limited their ability to provide services to their growing poor population and further hindered responses to the spread of communicable diseases

such as HIVAIDS and the growing prevalence of noncommunicable diseases. The COVID 19 Pandemic The emergence of the severe acute respiratory syndrome coronavirus 2 (SARS CoV 2) leading to the global pandemic of coronavirus disease 2019 (COVID 19) resulted in over 6 million deaths from COVID 19 and over 499 million cases of COVID 19 infection in the world (see Chapter 311). Children and adolescents tend to experience less severe illness and fewer deaths from SARS CoV 2 compared to adults, which may lead to lower rates of testing among children and contribute to transmission. Childhood COVID 19 infections have not affected countries equally, with early evidence showing pediatric deaths from COVID 19 to be significantly greater in LMICs compared to HICs. One study estimated 2.77 pediatric deaths1 million children in LMICs compared to 1.32 million children in HICs and higher rates of death among infants 1 year of age, at 0.07, in HICs versus 1.30 in LMICs. Although some LMICs settings are protected from COVID 19 infection by having a younger demographic profile, lower prevalence of the chronic condi tions predisposing to severe infection, and less international transport especially in remote, low income regions, they also suffer from limited personal protective equipment, poor ventilation of indoor spaces, and inequitable distribution of COVID 19 vaccines. Marginalized groups in these nations who are infected face inadequate medical support and supplies, which can greatly elevate their risk of death and disability. Furthermore, poor availability of testing leads to a large number of deaths and infections being underreported. The pandemic has significantly strained the already weak health and public health systems in LMICs, raising grave concerns about the risk for youth with chronic conditions. COVID 19 impact has led to disruptions in routine childhood vaccinations, lack of medical sup plies, shortages of a health workforce, and reduced delivery of lifesav ing services such as cardiac surgery. One estimate showed that 90 of countries report disruptions in essential health services such as essen tial medicines, routine childhood immunizations, and diagnostics, although some mitigation efforts are in place. COVID 19 and Social Determinants of Health COVID 19 affects child and adolescent health indirectly through the rippling effects on the worlds economies and disruption of national systems in public health, healthcare, food, and education, all which are feared to be more of a threat than the pandemic itself (Fig. 3.7). 1930 Q1 77 Q1Q2 77 Q2Q3 78 Q3Q4 80 Q4Q5 82 76 78 83 88 89 Q5 1960 70 E xp ec te d ag e at d ea th ( ye ar s) Birth cohort 75 80 85 90 Fig. 3.6 Projected life expectancy for U.S. men at age 50 for 1930 and 1960 birth cohorts by income quintile Q1 (poorest) to Q5 (richest).

Chapter 3 u Global Child Health 27 The economic crisis precipitated by the COVID pandemic lock down and supply chain disruptions places the greatest strain on low income communities, increasing the proportion of children who live in extreme poverty and face housing instability. An estimated additional 100 million children are estimated to have fallen into extreme poverty worldwide, which is the first increase in this indicator in 20 years. Pre existing disparities have widened during the pandemic both within countries and globally between LMICs and HICs. The COVID pandemic has stressed the social fabric of communi ties around the world so that the most marginalized and vulnerable bear the brunt of its full impact. Many racial and ethnic minority groups are unequally affected by COVID 19, with significantly higher rates of illness and death from COVID 19. Vulnerable communities that existed before the pandemic living in poverty, those employed in the informal sectors (e.g., street vendors), living within close proximity to others, unable to afford being able to stay safe at home, lacking protective gear at work, and without access to healthcare and health insurance are all at greater risk for COVID 19 infections. Children in LMICs are particularly vulnerable because of the pro longed shutdown of schools, resulting in loss of education without access to technologic online solutions to engage in the educational curriculum. The loss of safe school environments has also been attributed to further widening gender inequities, and several countries reported a surge in adolescent pregnancies, domestic violence, and child abuse after closures. Furthermore, the number of children affected by COVID 19asso ciated orphanhood and caregiver death has been estimated to have increased by 90. The loss of a mother is associated with increased child mortality, especially when maternal death occurs in the first year of the childs life. In regions where rates of maternal death were already high, the impact of COVID 19 leading to loss of a mother or another caregiver can have devastating impact on the lives of children in the short and long term.

19 pan demic for parents and their children; as the pandemic has progressed, the prevalence of depression and anxiety symptoms among adolescents has escalated. The impact on mental health is not surprising because of the extraordinary disruption of routines, recreation, family income, peer interaction, and school support. The pandemic further halted mental health services in 93 of countries worldwide as the demand for mental health services increased in settings where online mental health services are not an option. Sustainable Development Goals The prioritization and planning of global development and interna tional aid has been guided by international goals. In 2015, world lead ers agreed to 17 goals, the Sustainability Development Goals (SDGs), to improve global well being by 2030 (Fig. 3.8). The SDGs were built on the eight Millennium Development Goals (MDGs), which were concrete, specific, and measurable targets set by the United Nations in 2000 to eradicate poverty, hunger, illiteracy, and disease by 2015. The SDGs have become even more critical to countries planning for ways to mitigate the future impact of the COVID 19 pandemic on child health, particularly among marginalized communities and LMICs. The SDGs highlight recommended interventions for coun tries to meet their goals in the setting of the challenges created by the COVID 19 pandemic such as optimizing digital centers to increase access to public services, with an emphasis on targeting solutions for communities with low internet connectivity. There have been setbacks in progress towards meeting the 17 SDGs because of the COVID pandemic, highlighting the need to prioritize programs such as routine immunization services, malaria bed net distribution, fam ily planning, and antenatal care services to prevent further negative impacts on child health.

It includes health related subtargets, including to reduce U5MR to 25 deaths per 1,000 live births and neonatal mortality rate to 12 deaths per 1,000 live births by 2030. The other 16 SDGs focus mainly on social and economic determinants and the environment. This reflects an important shift to broaden the global targets to include upstream deter minants of health, including health systems, and socioeconomic, gender based, political, and environmental factors.

development, environmental sustainability, and social inclusion for all. The Global Strategy for Womens, Childrens and Adolescents Health 20162030 maps out the strategies to achieve the SDGs by cen tering on the goal of health for all women, children, and adolescents using evidence based approaches, backed by innovative and sustain able financing mechanisms. An important component of the Global Strategy is the inclusion of adolescents as central to the 2030 Agenda for Sustainable Development. In alignment with the SDGs, the Global Strategy focuses on three pillars of action: (1) ending preventable deaths among women, children, and adolescents, (2) ensuring their health and well being by ending malnutrition and ensuring access to family planning, reducing exposure to pollution, and achieving uni versal health coverage, and (3) expanding enabling environments by efforts such as eradicating extreme poverty, ensuring good quality education, eliminating violence against females, enhancing research and technologic capabilities, and encouraging innovation. In addition to being much broader in scope, the Global Strategy focuses on equity in that the strategy is meant to apply to all people, including the marginalized and difficult to reach populations, in all situations, including during crisis. Health insurance coverage would not be assessed based simply on the national average of coverage but also by how well the increases in coverage benefit all population groups regardless of income or educational level. EVIDENCE BASED INTERVENTIONS AND INNOVATIONS TO ADDRESS CHILD HEALTH INEQUITIES Estimates suggest that most of the 5.6 million annual deaths in chil dren younger than 5 could be averted by increasing implementa tion of proven low cost interventions (Table 3.1). Childhood deaths from diarrheal illness and pneumonia can be prevented by simple Table 3.1 Essential Interventions Across the Continuum of Care to Improve Child Survival HEALTH AND MULTISECTOR ACTIONS Ensuring food security for the family (or mother and child) Maternal education Safe drinking water and sanitation Handwashing with soap Reduced household air pollution Health education in schools AGE SPECIFIC ACTIONS PREVENTION TREATMENT Adolescence and Pre Pregnancy Family planning Preconception care Pregnancy Appropriate care for normal and high risk pregnancies (maternal tetanus vaccination) Antenatal steroids for premature births Intermittent preventive treatment for malaria Childbirth Maternal intrapartum care and monitoring Skilled delivery Thermal care for all newborns Clean cord and skin care Early initiation and exclusive breastfeeding within the first hour Newborn resuscitation (e.g., Healthy Babies Breathe) Premature: Surfactant administration, continuous positive airway pressure (CPAP), treatment of jaundice, feeding support for small preterm infants Kangaroo mother care Postnatal Period Appropriate postnatal visits Extra care for small and sick babies (kangaroo mother care, treatment of infection, support for feeding, and management of respiratory complications) Antibiotics for newborns at risk and for treatment of bacterial infections (PROM, sepsis, meningitis, pneumonia) Infancy and Childhood Exclusive breastfeeding for 6 mo and continued breastfeeding up to at least 2 yr with appropriate complementary feeding from 6 mo Monitoring and care for child growth and development Routine immunization for childhood diseases Micronutrient supplementation, including vitamin A, from 6 mo Prevention of childhood diseases Malaria (insecticide

Deaths related to undernutrition, which predisposes children to infectious diseases, may be prevented by proper infant and young child feeding practices, micronutrient supplementation, and community based screening and management of malnutrition. Addressing the SDGs to improve the health of mothers, children, and adolescents takes a life course approach. Figure 3.9 displays esti mates of coverage for essential interventions across the continuum of care, indicating the wide range of coverage rates within countries that will need to be addressed if SDGs are to be attained. Vaccine Preventable Diseases Vaccines prevent an estimated 2.5 million deaths per year among children under 5 years of age. One study predicted a reduction in 120 million deaths among children born between 2000 and 2030 with vaccination programs. Yet in 2019 an estimated 1.15 million under 5 deaths were the result of vaccine preventable diseases, with 99 of these children who died living in LMICs. Top contributors were Streptococcus pneumoniae and rotavirus, followed by Borde tella pertussis, measles virus, Haemophilus influenzae B (Hib), and influenza virus. The WHO Expanded Program on Immunization (EPI) has resulted in a dramatic reduction in deaths, illness, and disability from many of these diseases, in addition to the near elimination of poliomyelitis. Recommendations for routine immunizations have continued to grow with the development of new vaccines that have demonstrated significant lifesaving potential in industrialized countries (Table 3.2). The vulnerability of these programs was dem onstrated during the pandemic as global vaccine coverage dropped from 86 in 2019 to 83 in 2020, with an estimated 23 million under the age of 1 year who did not receive basic vaccines in 2020 the highest number since 2009. In 2015, 86 of the worlds infants were vaccinated with 3 doses of DTP. Although vaccines are very effective in improving child sur vival, rates of coverage are low in many countries. In 2016, a total of 19.5 million did not receive all routine lifesaving vaccinations, and 90,000 deaths were reported due to measles alone. Lifesaving vaccines are still not available in many countries, but progress has been made to expand availability to new countries every year. The lowest number of wild poliovirus cases were reported in 2016 (37 cases). The significant

declines in immunization coverage caused by the COVID 19 pandemic have increased the risk for a resurgence of these vaccine preventable infections amidst weakened healthcare systems. Reaching Every Child, Everywhere Global vaccine organizations aim for universal coverage of immu nizations but face challenges within countries to attain this goal. Other lifesaving interventions have met barriers to attaining uni versal coverage. Oral rehydration therapy has been the evidence based intervention to prevent dehydration from diarrheal disease since the 1970s, yet only 2 in 5 children under 5 with diarrheal ill ness receive this treatment. The determinants of whether or not a child receives a lifesaving intervention are multifactorial. Charac teristics of a healthcare system, the social attitudes and practices, and political climate affect whether universal coverage can be reached for evidence based essential interventions. Innovations to strengthen vaccine coverage to reach every child in every district of a country range from programs such as Reaching Every Child through Quality Improvement (REC QI), using community map ping techniques, to the integration of service delivery mechanisms and strengthening the health system with improved surveillance. Effective Delivery Strategies: Integrated Management of Childhood Illness Weak health systems impede the ability of countries to deliver cost effective interventions and lifesaving health messages for children. Such systems are characterized by insufficient numbers of health workers, low quality training and supervision, and poorly function ing supply chains. The provision of child health services may focus on a single level such as the health facility, but effective and lasting improvements can only be achieved with the integration of delivery at all levels, such as adequate referrals and follow up between com munity, clinic, and health facility. As countries resume health ser vices after the COVID 19 pandemic, an important component will be community based, lifesaving outreach services such as mass immu nization, vitamin A campaigns, and community based health promo tion activities (Fig. 3.10).
