The All of Us Data and Research Center: Creating a Secure, Scalable, and Sustainable Ecosystem for Biomedical Research.

The All of Us Research Program's Data and Research Center (DRC) was established to help acquire, curate, and provide access to one of the world's largest and most diverse datasets for precision medicine research. Already, over 500,000 participants are enrolled in All of Us, 80% of whom are underrepresented in biomedical research, and data are being analyzed by a community of over 2,300 researchers. The DRC created this thriving data ecosystem by collaborating with engaged participants, innovative program partners, and empowered researchers. In this review, we first describe how the DRC is organized to meet the needs of this broad group of stakeholders. We then outline guiding principles, common challenges, and innovative approaches used to build the All of Us data ecosystem. Finally, we share lessons learned to help others navigate important decisions and trade-offs in building a modern biomedical data platform.

Marked Disparities in COVID-19 Vaccination among US Children and Adolescents by Racial/Ethnic, Socioeconomic, Geographic, and Health Characteristics, United States, December 2021 - April 2022.

Background: The COVID-19 pandemic has had a substantial adverse impact on the health and well-being of populations in the United States (US) and globally. Although COVID-19 vaccine disparities among US adults aged ≥18 years are well documented, COVID-19 vaccination inequalities among US children are not well studied. Using the recent nationally representative data, we examine disparities in COVID-19 vaccination among US children aged 5-17 years by a wide range of social determinants and parental characteristics. Methods: Using the US Census Bureau's Household Pulse Survey from December 1, 2021 to April 11, 2022 (N=86,335), disparities in child vaccination rates by race/ethnicity, socioeconomic status, health insurance, parental vaccination status, parental COVID-19 diagnosis, and metropolitan area were modeled by multivariate logistic regression. Results: During December 2021-April 2022, an estimated 40.1 million or 57.2% of US children aged 5-17 received COVID-19 vaccination. Vaccination rates were lowest among children of parents aged 25-34 (34.9%) and highest among children of parents aged 45-54 (69.2%). Children of non-Hispanic Black parents, divorced/separated and single individuals, parents with lower education and household income levels, renters, not-employed parents, the uninsured, and parents without COVID-19 vaccination or with COVID-19 diagnoses had significantly lower rates of vaccination. Controlling for covariates, Asian and Hispanic children aged 5-17 had 134% and 47% higher odds of receiving vaccination than their non-Hispanic White counterparts. Children of parents with a high school education had 47% lower adjusted odds of receiving vaccination than children of parents with a master's degree or higher. Children with annual household income <$25,000 had 48% lower adjusted odds of vaccination than those with income ≥$200,000. Although vaccination rates were higher among children aged 12-17 than among children aged 5-11, sociodemographic patterns in vaccination rates were similar. Parental vaccination status was the strongest predictor of children's vaccination status. Vaccination rates for children aged 5-17 ranged from 49.6% in Atlanta, Georgia to 82.6% in San Francisco, California. Conclusion and Global Health Implications: Ethnic minorities, socioeconomically-disadvantaged children, uninsured children, and children of parents without COVID-19 vaccination or with COVID-19 diagnoses had significantly lower vaccination rates. Equitable vaccination coverage among children and adolescents is critical to reducing inequities in COVID-19 health outcomes in the US and globally.

Perinatal Acetaminophen Exposure and Childhood Attention-Deficit/Hyperactivity Disorder (ADHD): Exploring the Role of Umbilical Cord Plasma Metabolites in Oxidative Stress Pathways.

Oxidative stress mechanisms may explain associations between perinatal acetaminophen exposure and childhood attention-deficit hyperactivity disorder (ADHD). We investigated whether the changes in umbilical cord plasma amino acids needed to synthesize the antioxidant glutathione and in the oxidative stress biomarker 8-hydroxy-deoxyguanosine may explain the association between cord plasma acetaminophen and ADHD in the Boston Birth Cohort (BBC). Mother-child dyads were followed at the Boston Medical Center between 1998 and 2018. Cord plasma analytes were measured from archived samples collected at birth. Physician diagnoses of childhood ADHD were obtained from medical records. The final sample consisted of 568 participants (child mean age [SD]: 9.3 [3.5] years, 315 (52.8%) male, 248 (43.7%) ADHD, 320 (56.3%) neurotypical development). Cord unmetabolized acetaminophen was positively correlated with methionine (R = 0.33, p < 0.001), serine (R = 0.30, p < 0.001), glycine (R = 0.34, p < 0.001), and glutamate (R = 0.16, p < 0.001). Children with cord acetaminophen levels >50th percentile appeared to have higher risk of ADHD for each increase in cord 8-hydroxy-deoxyguanosine level. Adjusting for covariates, increasing cord methionine, glycine, serine, and 8-hydroxy-deoxyguanosine were associated with significantly higher odds for childhood ADHD. Cord methionine statistically mediated 22.1% (natural indirect effect logOR = 0.167, SE = 0.071, p = 0.019) and glycine mediated 22.0% (natural indirect effect logOR = 0.166, SE = 0.078, p = 0.032) of the association between cord acetaminophen >50th percentile with ADHD. Our findings provide some clues, but additional investigation into oxidative stress pathways and the association of acetaminophen exposure and childhood ADHD is warranted.

Global Ranking of COVID-19-Related Mortality by Country using a Novel Pandemic Efficiency Index (PEI).

The world is currently witnessing a dramatic disruption of everyday life owing to the rapid progression of the coronavirus disease 2019 (COVID-19) pandemic. As the pandemic evolves, there is an urgent need to better understand its epidemiology, characterize its potential impact, and identify mitigatory strategies to avert pandemic-related mortality. There is a need for a tool or algorithm to evaluate the extent to which public health policy and/or economic preparedness measures are effectively averting COVID-19 related mortality. We present a simple and yet practical epidemiological tool, the Pandemic Efficiency Index (PEI), that can be utilized globally to test the relative efficiency of measures put in place to avert death resulting from COVID-19 infection. Using the PEI and current COVID-19-related mortality, we determined that so far Germany demonstrates the highest PEI (5.1) among countries with more than 5,000 recorded cases of the infection, indicating high quality measures instituted by the country to avert death during the pandemic. Italy and France currently have the lowest COVID-19-related PEIs. Epidemics and pandemics come and go, but local, national, and global abilities to determine the efficiency of their efforts in averting deaths is critical.

Social Determinants of Health Associated with Mental Health Among U.S. Mothers with Children Aged 0-5 Years.

Background: Maternal mental illness is a significant public health problem during the perinatal period and beyond. Little is known about how social determinants of health (SDOH) affect maternal mental health. Materials and Methods: We used cross-sectional data from the 2016 to 2017 National Survey of Children's Health with 19,127 mothers of a nationally representative sample of U.S. children aged 0-5. We estimated the prevalence of poor reported mental health (reported as "fair"/"poor") among mothers with children aged 0-5 by SDOH. Multivariable logistic regression was used to examine factors associated with poor maternal mental health. Results: Approximately 4.5% of mothers with children aged 0-5 reported having poor mental health in 2016-2017. Postadjustment and mothers' poor mental health were significantly associated with age (adjusted odds ratio [AOR]: 18-20 years: 2.77, 95% confidence interval [CI]: 1.35-5.67; 21-24 years AOR: 2.14, 95% CI: 1.22-3.73, and 30-34 years AOR: 1.97, 95% CI: 1.13-3.43), U.S.-born status (AOR: 2.31, 95% CI: 1.48-3.63), poor physical health (AOR: 8.69, 95% CI: 5.81-13.02), having a child with a special health care need (AOR: 1.65, 95% CI: 1.03-2.64), experiencing food insecurity (afford enough food, yet, unhealthy [AOR: 2.74, 95% CI: 1.59-4.70] and sometimes/often not afford enough food [AOR: 3.20, 95% CI: 1.76-5.84]), and low social capital (AOR: 1.97, 95% CI: 1.04-3.73). Conclusion: Mothers with children aged 0-5 who had poor physical health and experienced food insecurity were at the greatest risk for poor mental health. Integrated perinatal and behavioral health models, screening, and referrals may help identify and treat mothers experiencing these issues.

Maternal and Child Health Bureau's Autism Research Program.

OBJECTIVES: To provide an overview and quantitatively demonstrate the reach of the Health Resources and Services Administration's Maternal and Child Health Bureau autism research program. METHODS: We reviewed program reports and internal data from 59 autism research grantees. The US federal Interagency Autism Coordinating Committee's strategic plan questions were used as a framework to highlight the contributions of the autism research program in advancing the field. RESULTS: The autism research program grantees advance research in several ways. Grantees have strengthened the evidence for autism interventions by conducting 89 studies at 79 distinct research sites. A total of 212 708 participants have enrolled in autism research program studies and 361 researchers have contributed to furthering autism research. The program addresses topics that align with the majority of the Interagency Autism Coordinating Committee's priority topic areas, including advancements in treatments and interventions, services and supports, and identifying risk factors. Grantee products include 387 peer-reviewed publications, 19 tools, and 13 practice guidelines for improving care and intervention practices. CONCLUSIONS: The autism research program has contributed to medical advances in research, leveraged innovative training platforms to provide specialized training, and provided access to health services through research-based screening and diagnostic procedures. Autism research program studies have contributed to the development of evidence-based practice guidelines, informed policy guidelines, and quality improvement efforts to bolster advancements in the field. Although disparities still exist, the Health Resources and Services Administration's Maternal and Child Health Bureau can reduce gaps in screening and diagnosis by targeting interventions to underserved populations including minority and rural communities.

Current and Emerging Issues in Global Health: An Introduction to Special Journal Collection.

We are thrilled to present this special collection of articles entitled "Current and Emerging Issues in Global Health." This special collection pursued three main goals. First, the collection presents an opportunity for innovation. Second, it presents an opportunity to engage the field and community around a common theme. Finally, the collection provides a reality-check for the journal editors to support the field in evaluating the extent to which we have collectively attempted to confront the global maternal and child health (MCH) issues of our time regardless of where in the world we live. Unique to this special collection is the geographical spread of the article submissions. We have articles and contributions from researchers and research groups from three continents in a single edition: Africa, Asia and North America, making the articles opportunities for cross-fertilization of ideas across the global North and South. Public health is passing through a seismic transformation. Whether at the global, national, state, and local levels, disease outbreaks, patient demographics, and health technology have changed the global health landscape in a way never imagined. Our hope is that papers in this special collection will spark new ideas for invention, improved patient care, and transform population health.

Association of Cord Plasma Biomarkers of In Utero Acetaminophen Exposure With Risk of Attention-Deficit/Hyperactivity Disorder and Autism Spectrum Disorder in Childhood.

Importance: Prior studies have raised concern about maternal acetaminophen use during pregnancy and increased risk of attention-deficit/hyperactivity disorder (ADHD) and autism spectrum disorder (ASD) in their children; however, most studies have relied on maternal self-report. Objective: To examine the prospective associations between cord plasma acetaminophen metabolites and physician-diagnosed ADHD, ASD, both ADHD and ASD, and developmental disabilities (DDs) in childhood. Design, Setting, and Participants: This prospective cohort study analyzed 996 mother-infant dyads, a subset of the Boston Birth Cohort, who were enrolled at birth and followed up prospectively at the Boston Medical Center from October 1, 1998, to June 30, 2018. Exposures: Three cord acetaminophen metabolites (unchanged acetaminophen, acetaminophen glucuronide, and 3-[N-acetyl-l-cystein-S-yl]-acetaminophen) were measured in archived cord plasma samples collected at birth. Main Outcomes and Measures: Physician-diagnosed ADHD, ASD, and other DDs as documented in the child's medical records. Results: Of 996 participants (mean [SD] age, 9.8 [3.9] years; 548 [55.0%] male), the final sample included 257 children (25.8%) with ADHD only, 66 (6.6%) with ASD only, 42 (4.2%) with both ADHD and ASD, 304 (30.5%) with other DDs, and 327 (32.8%) who were neurotypical. Unchanged acetaminophen levels were detectable in all cord plasma samples. Compared with being in the first tertile, being in the second and third tertiles of cord acetaminophen burden was associated with higher odds of ADHD diagnosis (odds ratio [OR] for second tertile, 2.26; 95% CI, 1.40-3.69; OR for third tertile, 2.86; 95% CI, 1.77-4.67) and ASD diagnosis (OR for second tertile, 2.14; 95% CI, 0.93-5.13; OR for third tertile, 3.62; 95% CI, 1.62-8.60). Sensitivity analyses and subgroup analyses found consistent associations between acetaminophen buden and ADHD and acetaminophen burden and ASD across strata of potential confounders, including maternal indication, substance use, preterm birth, and child age and sex, for which point estimates for the ORs vary from 2.3 to 3.5 for ADHD and 1.6 to 4.1 for ASD. Conclusions and Relevance: Cord biomarkers of fetal exposure to acetaminophen were associated with significantly increased risk of childhood ADHD and ASD in a dose-response fashion. Our findings support previous studies regarding the association between prenatal and perinatal acetaminophen exposure and childhood neurodevelopmental risk and warrant additional investigations.

Father's Health Status and Inequalities in Physical and Mental Health of U.S. Children: A Population-Based Study.

Introduction: Father-and-child-health risk relationship is poorly studied and understood. We examine the impact of father's physical and mental health status and sociodemographic characteristics on the physical and mental outcomes of U.S. children 0-17 years of age. Methods: The 2011-2012 National Survey of Children's Health (N=75,879) was analyzed to estimate prevalence and odds of poor physical and mental health among children according to father's physical and mental health status and sociodemographic characteristics. Results: Overall, 3.2% of U.S. children had poor physical health; and 6.0% of U.S. children had emotional or behavioral problems. The adjusted odds of having poor overall health was 3.1 times higher among children of fathers with poor overall health. Children of fathers with poor mental health had 2.6 times higher adjusted odds of having poor mental health. Discussion: Results underscore the significant role of fathers in the physical and mental well-being of children. Engaging fathers in child health may provide a potential opportunity to reduce mental and emotional health problems among children.

Association Between Maternal Exposure to Lead, Maternal Folate Status, and Intergenerational Risk of Childhood Overweight and Obesity.

Importance: The first pediatric lead screening typically occurs at 1-year well-child care visits. However, data on the extent of maternal lead exposure and its long-term consequences for child health are lacking. Objective: To investigate the associations between maternal red blood cell (RBC) lead levels and intergenerational risk of overweight or obesity (OWO) and whether adequate maternal folate status is associated with a reduction in OWO risk. Design, Setting, and Participants: Prospective birth cohort study. The analysis was conducted from July 14, 2018, to August 2, 2019, at Johns Hopkins Bloomberg School of Public Health. This study included 1442 mother-child pairs recruited at birth from October 27, 2002, to October 10, 2013, and followed up prospectively at Boston Medical Center. Main Outcomes and Measures: Child body mass index (BMI) z score, calculated according to US national reference data, and OWO, defined as BMI at or exceeding the 85th percentile for age and sex. Maternal RBC lead levels and plasma folate levels were measured in samples obtained 24 to 72 hours after delivery; child whole-blood lead level was obtained from the first pediatric lead screening. Results: The mean (SD) age of mothers and children was 28.6 (6.5) years and 8.1 (3.1) years, respectively; 50.1% of children were boys. The median maternal RBC lead level and plasma folate level were 2.5 (interquartile range [IQR], 1.7-3.8) µg/dL and 32.2 (IQR, 22.1-44.4) nmol/L, respectively. The median child whole-blood lead level and child BMI z score were 1.4 (IQR, 1.4-2.0) µg/dL and 0.78 (IQR, -0.08 to 1.71), respectively. Maternal RBC lead level was associated with child OWO risk in a dose-response fashion, with an odds ratio (OR) of 1.65 (95% CI, 1.18-2.32) for high maternal RBC lead level (≥5.0 µg/dL) compared with low maternal RBC lead level (<2.0 µg/dL). Child OWO was highest among children of OWO mothers with high RBC lead levels (adjusted OR, 4.24; 95% CI, 2.64-6.82) compared with children of non-OWO mothers with low RBC lead levels. Children of OWO mothers with high RBC lead levels had 41% lower OWO risk (OR, 0.59; 95% CI, 0.36-0.95; P = .03) if their mothers had adequate plasma folate levels (≥20.4 nmol/L) compared with their counterparts. Conclusions and Relevance: In this sample of a US urban population, findings suggest that maternal elevated lead exposure was associated with increased risk of intergenerational OWO independent of postnatal blood lead levels. Adequate maternal folate status appeared to be associated with lower OWO risk. If confirmed by additional studies, these findings have implications for prenatal lead screening and management to minimize adverse health consequences on children.

Prenatal Risk Factors and Perinatal and Postnatal Outcomes Associated With Maternal Opioid Exposure in an Urban, Low-Income, Multiethnic US Population.

Importance: The opioid epidemic increasingly affects pregnant women and developing fetuses, resulting in high rates of neonatal abstinence syndrome. However, longitudinal studies that prospectively observe newborns with neonatal abstinence syndrome or with maternal opioid use and examine their long-term physical and neurodevelopmental outcomes are lacking. Objective: To examine prenatal risk factors associated with maternal opioid use during pregnancy and the short-term and long-term health consequences on their children. Design, Setting, and Participants: This cohort study analyzed data from the Boston Birth Cohort, an urban, low-income, multiethnic cohort that enrolled mother-newborn pairs at birth at Boston Medical Center (Boston, Massachusetts) starting in 1998, and a subset of children were prospectively observed at Boston Medical Center pediatric primary care and subspecialty clinics from birth to age 21 years. Data analysis began in June 2018 and was completed in May 2019. Exposures: In utero opioid exposure was defined as maternal self-reported opioid use and/or clinical diagnosis of neonatal abstinence syndrome. Main Outcomes and Measures: Pregnancy outcomes, postnatal child physical health, and major neurodevelopmental disabilities, documented in maternal and child medical records. Results: This study included 8509 Boston Birth Cohort mother-newborn pairs for prenatal and perinatal analyses. Of those, 3153 children continued to receive pediatric care at Boston Medical Center and were included in assessing postnatal outcomes. Overall, 454 of the 8509 children (5.3%) in the Boston Birth Cohort had in utero opioid exposure. At birth, opioid exposure was associated with higher risks of fetal growth restriction (odds ratio [OR], 1.87; 95% CI, 1.41-2.47) and preterm birth (OR, 1.49; 95% CI, 1.19-1.86). Opioid exposure was associated with increased risks of lack of expected physiological development (OR, 1.80; 95% CI, 1.17-2.79) and conduct disorder/emotional disturbance (OR, 2.13; 95% CI, 1.20-3.77) among preschool-aged children. In school-aged children, opioid exposure was associated with a higher risk of attention-deficit/hyperactivity disorder (OR, 2.55; 95% CI, 1.42-4.57). Conclusions and Relevance: In this sample of urban, high-risk, low-income mother-child pairs, in utero opioid exposure was significantly associated with adverse short-term and long-term outcomes across developmental stages, including higher rates of physical and neurodevelopmental disorders in affected children. Efforts to prevent the opioid epidemic and mitigate its health consequences would benefit from more intergenerational research.

Mentoring, Bullying, and Educational Outcomes Among US School-Aged Children 6-17 Years.

BACKGROUND: Ensuring the optimum development of all children and their attainment of age-appropriate educational outcomes is of great interest to public health researchers and professionals. Bullying and mentoring have opposite effects on child development and educational attainment. Mentoring exerts protective effects on youths against risky behaviors; however, the protective effects of community-oriented natural or informal mentoring on educational outcomes and bullying are largely underexplored. We examine associations between mentoring, bullying, and educational outcomes among US school-aged children 6-17 years. METHODS: We analyzed the 2011-2012 National Survey of Children's Health (N = 65,593) to estimate prevalence and odds of repeating a grade in school, lower school engagement, and bullying perpetration according to mentoring receipt and sociodemographic characteristics. RESULTS: Overall, 5.4% of US school-aged children without a mentor perpetrated bullying against other children; 11.4% repeated more than one grade in school; and 23.0% had low school engagement. Children without mentors had 2.1 and 1.3 times higher adjusted odds, respectively, of bullying other children and low school engagement than those with mentors. Proportion of children who bullied others or repeated grades was higher among minority children. CONCLUSIONS: Findings indicate that mentoring may be a pathway for providing programs that prevent bullying and improve educational outcomes among school-aged children.

Ebola Virus Disease Epidemic: What Can the World Learn and Not Learn from West Africa?

With over 4,500 deaths and counting, and new cases identified in two developed countries that are struggling and faltering in their handling of the epidemic, the 2014 Ebola Virus Disease (EVD) epidemic is unlike any of its kind ever encountered. The ability of some poor, resource-limited, developing countries in sub-Saharan Africa to efficiently handle the epidemic within their shores provides some lessons learned for the global health community. Among others, the 2014 EVD epidemic teaches us that it is time to put the "P" back in public and population health around the world. The global health community must support a sustainable strategy to mitigate Ebola virus and other epidemics both within and outside their shores, even after the cameras are gone. Ebola virus must not be called the disease of the poor and developing world.

Global Inequalities in Youth Mortality, 2007-2012.

OBJECTIVES: There is limited cross-national research on youth mortality. We examined age-and gender-variations in all-cause mortality among youth aged 15-34 years across 52 countries. METHODS: Using the 2014 WHO mortality database, mortality rates for all countries were computed for the latest available year between 2007 and 2012. Rates, rate ratios, and ordinary least squares (OLS) and Poisson regression were used to analyze international variation in mortality. RESULTS: Mortality rates among youth aged 15-34 years varied from a low of 28.4 deaths per 100,000 population for Hong Kong to a high of 250.6 for Russia and 619.1 for South Africa. For men aged 15-34, Singapore and Hong Kong had the lowest mortality rates (≈40 per 100,000), compared with South Africa and Russia with rates of 589.7 and 383.3, respectively. Global patterns in mortality among women were similar. Youth aged 15-24 in South Africa had 14 times higher mortality and those in the Philippines, Mexico, Russia, Colombia, and Brazil had 5-7 times higher mortality than those in Hong Kong. Youth aged 25-34 in Russia and South Africa had, respectively, 10 and 29 times higher mortality than their counterparts in Hong Kong. United States (US) had the 12th highest mortality rate among youth aged 15-24 and the 13th highest rate among youth aged 25-34. Overall, the US youth had 2-3 times higher rates of mortality than their counterparts in many industrialized countries including Hong Kong, Singapore, Netherlands, Switzerland, Germany, Norway, and Sweden. Income inequality, unemployment rate, and human development explained 50-66% of the global variance in youth mortality. Compared to the countries with low unemployment and income inequality and high human development levels, countries with high unemployment and income inequality and low human development had, respectively, 343%, 213%, and 205% higher risks of youth mortality. CONCLUSIONS AND GLOBAL HEALTH IMPLICATIONS: Marked international disparities in youth all-cause mortality largely reflect differences in violence and injury deaths and in such risk factors as unemployment, income inequality, human development, and alcohol consumption. The US ranks in the upper quartile of all-cause mortality, with youth in Canada and many western industrialized countries showing signifi cantly lower mortality risks than the US youth.

Overcoming Challenges in Conducting Clinical Trials in Minority Populations: Identifying and Testing What Works.

Participation in clinical trials is one of the greatest gifts that humanity can give to the fields of medicine and public health. Clinical trials are central in public health's mission to advance drug discovery. The enrollment and retention of participants, especially minority populations, is one of the most practical challenges of successfully implementing a clinical trial. In spite of these challenges, there are many reasons why a broader public participation in clinical trials is critical. The ability to generalize the scientific findings and the principles of equity, justice, and beneficence require an equitable distribution of the risks, benefits, and burdens of research for all classes and groups of people. A new methodology article published in this journal presents a promising framework for addressing minority recruitment and retention using what is known and using it innovatively to address a difficult problem facing clinical trials and public health. The innovative application of what is known in addressing a challenging problem, as this article presents, is worth the reading of all those interested in scientifically rigorous and ethically sound clinical trials that substantially comprise of diverse populations.

Widening Socioeconomic and Racial Disparities in Cardiovascular Disease Mortality in the United States, 1969-2013.

OBJECTIVES: This study examined trends and socioeconomic and racial/ethnic disparities in cardiovascular disease (CVD) mortality in the United States between 1969 and 2013. METHODS: National vital statistics data and the National Longitudinal Mortality Study were used to estimate racial/ethnic and area- and individual-level socioeconomic disparities in CVD mortality over time. Rate ratios and log-linear regression were used to model mortality trends and differentials. RESULTS: Between 1969 and 2013, CVD mortality rates decreased by 2.66% per year for whites and 2.12% for blacks. Racial disparities and socioeconomic gradients in CVD mortality increased substantially during the study period. In 2013, blacks had 30% higher CVD mortality than whites and 113% higher mortality than Asians/Pacific Islanders. Compared to those in the most affluent group, individuals in the most deprived area group had 11% higher CVD mortality in 1969 but 40% higher mortality in 2007-2011. Education, income, and occupation were inversely associated with CVD mortality in both men and women. Men and women with low education and incomes had 46-76% higher CVD mortality risks than their counterparts with high education and income levels. Men in clerical, service, farming, craft, repair, construction, and transport occupations, and manual laborers had 30-58% higher CVD mortality risks than those employed in executive and managerial occupations. CONCLUSIONS AND GLOBAL HEALTH IMPLICATIONS: Socioeconomic and racial disparities in CVD mortality are marked and have increased over time because of faster declines in mortality among the affluent and majority populations. Disparities in CVD mortality may reflect inequalities in the social environment, behavioral risk factors such as smoking, obesity, physical inactivity, disease prevalence, and healthcare access and treatment. With rising prevalence of many chronic disease risk factors, the global burden of cardiovascular diseases is expected to increase further, particularly in low- and middle-income countries where over 80% of all CVD deaths occur.

Increasing Area Deprivation and Socioeconomic Inequalities in Heart Disease, Stroke, and Cardiovascular Disease Mortality Among Working Age Populations, United States, 1969-2011.

OBJECTIVES: We examined the extent to which area- and individual-level socioeconomic inequalities in cardiovascular-disease (CVD), heart disease, and stroke mortality among United States men and women aged 25-64 years changed between 1969 and 2011. METHODS: National vital statistics data and the National Longitudinal Mortality Study were used to estimate area- and individual-level socioeconomic gradients in mortality over time. Rate ratios and log-linear and Cox regression were used to model mortality trends and differentials. RESULTS: Area socioeconomic gradients in mortality from CVD, heart disease, and stroke increased substantially during the study period. Compared to those in the most affluent group, individuals in the most deprived area group had, respectively 35%, 29%, and 73% higher CVD, heart disease, and stroke mortality in 1969, but 120-121% higher mortality in 2007-2011. Gradients were steeper for women than for men. Education, income, and occupation were inversely associated with CVD, heart disease, and stroke mortality, with individual-level socioeconomic gradients being steeper during 1990-2002 than in 1979-1989. Individuals with low education and incomes had 2.7 to 3.7 times higher CVD, heart disease, and stroke mortality risks than their counterparts with high education and income levels. CONCLUSIONS AND GLOBAL HEALTH IMPLICATIONS: Although mortality declined for all US groups during 1969-2011, socioeconomic disparities in mortality from CVD, heart disease and stroke remained marked and increased over time because of faster declines in mortality among higher socioeconomic groups. Widening disparities in mortality may reflect increasing temporal areal inequalities in living conditions, behavioral risk factors such as smoking, obesity and physical inactivity, and access to and use of health services. With social inequalities and prevalence of smoking, obesity, and physical inactivity on the rise, most segments of the working-age population in low- and middle-income countries will likely experience increased cardiovascular-disease burden in terms of higher morbidity and mortality rates.

Widening Geographical Disparities in Cardiovascular Disease Mortality in the United States, 1969-2011.

OBJECTIVES: This study examined trends in geographical disparities in cardiovascular-disease (CVD) mortality in the United States between 1969 and 2011. METHODS: National vital statistics data and the National Longitudinal Mortality Study were used to estimate regional, state, and county-level disparities in CVD mortality over time. Log-linear, weighted least squares, and Cox regression were used to analyze mortality trends and differentials. RESULTS: During 1969-2011, CVD mortality rates declined fastest in New England and Mid-Atlantic regions and slowest in the Southeast and Southwestern regions. In 1969, the mortality rate was 9% higher in the Southeast than in New England, but the differential increased to 48% in 2011. In 2011, Southeastern states, Mississippi and Alabama, had the highest CVD mortality rates, nearly twice the rates for Minnesota and Hawaii. Controlling for individual-level covariates reduced state differentials. State- and county-level differentials in CVD mortality rates widened over time as geographical disparity in CVD mortality increased by 50% between 1969 and 2011. Area deprivation, smoking, obesity, physical inactivity, diabetes prevalence, urbanization, lack of health insurance, and lower access to primary medical care were all significant predictors of county-level CVD mortality rates and accounted for 52.7% of the county variance. CONCLUSIONS AND GLOBAL HEALTH IMPLICATIONS: Although CVD mortality has declined for all geographical areas in the United States, geographical disparity has widened over time as certain regions and states, particularly those in the South, have lagged behind in mortality reduction. Geographical disparities in CVD mortality reflect inequalities in socioeconomic conditions and behavioral risk factors. With the global CVD burden on the rise, monitoring geographical disparities, particularly in low- and middle-income countries, could indicate the extent to which reductions in CVD mortality are achievable and may help identify effective policy strategies for CVD prevention and control.

Exclusive Breastfeeding and Under-Five Mortality, 2006-2014: A Cross-National Analysis of 57 Low- and-Middle Income Countries.

BACKGROUND: Few studies have examined the long-term, cross-national, and population-level impacts of exclusive breastfeeding on major global child health indicators. We investigated the overall and independent associations between exclusive breastfeeding and under-five mortality in 57 low- and-middle-income countries. METHODS: Data were obtained from the latest World Health Organization, United Nations, and United Nations Children's Fund databases for 57 low- and middle-income countries covering the periods 2006-2014. Multivariate linear regression was used to estimate the effects of exclusive breastfeeding on under-five mortality after adjusting for differences in socioeconomic, demographic, and health-related factors. RESULTS: In multivariate models, exclusive breastfeeding was independently associated with under-five mortality after adjusting for sociodemographic and health systems-related factors. A 10 percentage-points increase in exclusive breastfeeding was associated with a reduction of 5 child deaths per 1,000 live births. A one-unit increase in Human Development Index was associated with a decrease of 231 under-five child deaths per 1,000 live births. A $100 increase in per capita health care expenditure was associated with a decrease of 2 child deaths per 1,000 live births. One unit increase in physician density was associated with 2.8 units decrease in the under-five mortality rate. CONCLUSIONS AND GLOBAL HEALTH IMPLICATIONS: Population-level health system and socioeconomic factors exert considerable effect on the association between exclusive breastfeeding and under-five mortality. Given that the health policy and socioeconomic indicators shown to influence exclusive breastfeeding and under-five mortality are modifiable, policy makers could potentially target specific policies and programs to address national-level deficiencies in these sectors to reduce under-five mortality in their countries.

Geographic, Racial/Ethnic, and Sociodemographic Disparities in Parent-Reported Receipt of Family-Centered Care among US Children.

This study examined geographic, racial/ethnic, and sociodemographic disparities in parental reporting of receipt of family-centered care (FCC) and its components among US children aged 0-17 years. We used the 2011-2012 National Survey of Children's Health to estimate the prevalence and odds of not receiving FCC by covariates. Based on parent report, 33.4% of US children did not receive FCC. Children in Arizona, Mississippi, Nevada, California, New Jersey, Virginia, Florida, and New York had at least 1.51 times higher adjusted odds of not receiving FCC than children in Vermont. Non-Hispanic Black and Hispanic children had 2.11 and 1.58 times higher odds, respectively, of not receiving FCC than non-Hispanic White children. Children from non-English-speaking households had 2.23 and 2.35 times higher adjusted odds of not receiving FCC overall and their doctors not spending enough time in their care than children from English-speaking households, respectively. Children from low-education and low-income households had a higher likelihood of not receiving FCC. The clustering of children who did not receive FCC and its components in several Southern and Western US states, as well as children from poor, uninsured, and publicly insured and of minority background, is a cause for concern in the face of federal policies to reduce health care disparities.
