"Outside the Skin": The Persistence of Black-White Disparities in U.S. Early-Life Mortality.

Research on Black-White disparities in mortality emphasizes the cumulative pathways through which racism gets "under the skin" to affect health. Yet this framing is less applicable in early life, when death is primarily attributable to external causes rather than cumulative, biological processes. We use mortality data from the National Vital Statistics System Multiple Cause of Death files and population counts from the Surveillance, Epidemiology, and End Result Program to analyze 705,801 deaths among Black and White males and females, ages 15-24. We estimate age-standardized death rates and single-decrement life tables to show how all-cause and cause-specific mortality changed from 1990 to 2016 by race and sex. Despite overall declines in early-life mortality, Black-White disparities remain unchanged across several causes-especially homicide, for which mortality is nearly 20 times as high among Black as among White males. Suicide and drug-related deaths are higher among White youth during this period, yet their impact on life expectancy at birth is less than half that of homicide among Black youth. Critically, early-life disparities are driven by preventable causes of death whose impact occurs "outside the skin," reflecting racial differences in social exposures and experiences that prove harmful for both Black and White adolescents and young adults.

The National Death Index as a Source of Homicide Data: A Methodological Exposition of Promises and Pitfalls for Criminologists.

Criminologists largely rely on national de-identified data sources to study homicide in the United States. The National Death Index (NDI), a comprehensive and well-established database compiled by the National Center for Health Statistics, is an untapped source of homicide data that offers identifiable linkages to other data sources while retaining national coverage. This study's five aims follow. First, we review the data sources in articles published in Homicide Studies over the past decade. Second, we describe the NDI, including its origins, procedures, and uses. Third, we outline the procedures for linking a police gang intelligence database to the NDI. Fourth, we introduce the St. Louis Gang Member-Linked Mortality Files database, which is composed of 3,120 police-identified male gang members in the St. Louis area linked to NDI records. Finally, we report on preliminary cause-of-death findings. We conclude by outlining the benefits and drawbacks of the NDI as a source of homicide data for criminologists.

Exceptional mortality risk among police-identified young black male gang members.

Gang membership is associated with many risky behaviors but is often overlooked as a source of mortality among young Americans. Gang Member-Linked Mortality Files (GM-LMFs) match St. Louis, Missouri gang members listed in a law enforcement gang database to mortality records in the National Death Index. We created three analytic samples composed of black males aged 15-35 years by merging cases of the GM-LMFs with National Vital Statistics System and Census data in years 1993-2016. Mortality rates standardized to the 15-35-year-old 2010 U.S. male population were estimated for all-cause (1477.4, 99% CI = 1451.5-1503.3), homicide (950.1, 99% CI = 932.2-967.9), non-homicide injury (314.0, 99% CI = 308.8-319.2), and non-injury (213.3, 99% CI = 202.3-224.4) deaths in the GM-LMFs. We fitted Poisson rate models to estimate mortality rate ratios (RR) between gang members and demographically-matched comparison groups. Black male gang members in St. Louis were at an elevated mortality risk from all causes of death, and homicides contributed substantially to this risk. Compared to black males in St. Louis, gang members experienced greater relative risk of all-cause (RR = 2.9, 99% CI = 2.4-3.5), homicide (RR = 3.2, 99% CI = 2.5-4.1), and non-homicide injury (RR = 4.0, 99% CI = 2.8-5.8) mortality between 1993 and 2016. Relative risk was greater when compared to black males in St. Louis MSA, Missouri, and the USA. These results identify a key source of excess mortality among young black Americans. Health policies and interventions may be most efficacious when they acknowledge, address, and incorporate information about and target high-risk populations, including gang members, that contribute to relatively high mortality risk in the USA.

Greater mortality variability in the United States in comparison with peer countries.

BACKGROUND: Over the past several decades, US mortality declines have lagged behind other high-income countries. However, scant attention has been devoted to how US mortality variability compares with other countries. OBJECTIVE: We examine trends in mortality and mortality variability in the US and 16 peer countries from 1980 through 2016. METHODS: We employ the Human Mortality Database and demographic techniques - with a focus on patterns in the interquartile (IQR), interdecile (IDR), and intercentile (ICR) ranges of survivorship - to better understand US mortality and mortality variability trends in comparative perspective. RESULTS: Compared to other high-income countries, the US: (1) mortality ranking has slipped for nearly all age groups; (2) is losing its old age mortality advantage; (3) has seen growth in relative age-specific mortality gaps from infancy through midlife; and (4) exhibits greater concentrations of deaths from infancy through adulthood, resulting in much greater mortality variability. CONCLUSIONS: We contribute to calls for renewed attention to the relatively low and lagging US life expectancy. The ICR draws particular attention to the comparatively high US early and midlife mortality. CONTRIBUTION: We find comparatively high variability in US mortality. Further reductions in early and midlife mortality could diminish variability, reduce years of potential life lost, and increase life expectancy. Consistent with previous research, we encourage policymakers to focus on reducing the unacceptably high early and midlife mortality in the US. And we urge researchers to more frequently monitor and track mortality variation in conjunction with mortality rates and life expectancy estimates.

The persistent southern disadvantage in US early life mortality, 1965-2014.

BACKGROUND: Recent studies of US adult mortality demonstrate a growing disadvantage among southern states. Few studies have examined long-term trends and geographic patterns in US early life (ages 1 to 24) mortality, ages at which key risk factors and causes of death are quite different than among adults. OBJECTIVE: This article examines trends and variations in early life mortality rates across US states and census divisions. We assess whether those variations have changed over a 50-year time period and which causes of death contribute to contemporary geographic disparities. METHODS: We calculate all-cause and cause-specific death rates using death certificate data from the Multiple Cause of Death files, combining public-use files from 1965-2004 and restricted data with state geographic identifiers from 2005-2014. State population (denominator) data come from US decennial censuses or intercensal estimates. RESULTS: Results demonstrate a persistent mortality disadvantage for young people (ages 1 to 24) living in southern states over the last 50 years, particularly those located in the East South Central and West South Central divisions. Motor vehicle accidents and homicide by firearm account for most of the contemporary southern disadvantage in US early life mortality. CONTRIBUTION: Our results illustrate that US children and youth living in the southern United States have long suffered from higher levels of mortality than children and youth living in other parts of the country. Our findings also suggest the contemporary southern disadvantage in US early life mortality could potentially be reduced with state-level policies designed to prevent deaths involving motor vehicles and firearms.

Family Socioeconomic Status and Early Life Mortality Risk in the United States.

OBJECTIVES: We examine the association between several dimensions of parental socioeconomic status (SES) and all-cause and cause-specific mortality among children and youth (ages 1-24) in the United States. METHODS: We use Cox proportional hazard models to estimate all-cause and cause-specific mortality risk based on data from the 1998 to 2015 National Health Interview Survey-Linked Mortality Files (NHIS-LMFs), restricted to children and youth ages 1-17 at the time of survey followed through age 24, or the end of the follow-up period in 2015 (N = 377,252). RESULTS: Children and youth in families with lower levels of mother's education, father's education, and/or family income-to-needs ratio exhibit significantly higher all-cause mortality risk compared with children and youth living in higher SES families. For example, compared to children and youth living with mothers who earned college degrees, those living with mothers who have not graduated high school experience 40% higher risk of early life mortality over the follow-up period, due in part to higher mortality risks of unintentional injuries and homicides. Similarly, children/youth whose fathers did not graduate high school experience a 41% higher risk of dying before age 25 compared to those with fathers who completed college. CONCLUSIONS: Today's children and youth experience clear disparities in mortality risk across several dimensions of parental SES. As the U.S. continues to lag behind other high-income countries in health and mortality, more attention and resources should be devoted to improving children's health and well-being, including the family and household contexts in which American children live.

Cigarette Smoking and All-Cause and Cause-Specific Adult Mortality in the United States.

This study illuminates the association between cigarette smoking and adult mortality in the contemporary United States. Recent studies have estimated smoking-attributable mortality using indirect approaches or with sample data that are not nationally representative and that lack key confounders. We use the 1990-2011 National Health Interview Survey Linked Mortality Files to estimate relative risks of all-cause and cause-specific mortality for current and former smokers compared with never smokers. We examine causes of death established as attributable to smoking as well as additional causes that appear to be linked to smoking but have not yet been declared by the U.S. Surgeon General to be caused by smoking. Mortality risk is substantially elevated among smokers for established causes and moderately elevated for additional causes. We also decompose the mortality disadvantage among smokers by cause of death and estimate the number of smoking-attributable deaths for the U.S. adult population ages 35+, net of sociodemographic and behavioral confounders. The elevated risks translate to 481,887 excess deaths per year among current and former smokers compared with never smokers, 14 % to 15 % of which are due to the additional causes. The additional causes of death contribute to the health burden of smoking and should be considered in future studies of smoking-attributable mortality. This study demonstrates that smoking-attributable mortality must remain a top population health priority in the United States and makes several contributions to further underscore the human costs of this tragedy that has ravaged American society for more than a century.

A longitudinal examination of US teen childbearing and smoking risk.

BACKGROUND: Teenage motherhood and smoking have important health implications for youth in the United States and globally, but the link between teen childbearing and subsequent smoking is inadequately understood. The selection of disadvantaged young women into early childbearing and smoking may explain higher smoking levels among teen mothers, but teen motherhood may also shape subsequent smoking through compromised maternal depression or socioeconomic status, and race/ethnicity may condition these processes. OBJECTIVE: This study examines the relationship between US teen childbearing and subsequent daily smoking, accounting for prior smoking and selection processes related to social disadvantage. Analyses investigate whether socioeconomic status and depression in young adulthood explained any relationship between teen childbearing and daily smoking, as well as examining racial/ethnic heterogeneity in these processes. METHODS: Multivariate binary logistic regression analyses employ the National Longitudinal Study of Adolescent to Adult Health (Add Health; N = 7,529). RESULTS: The highest daily smoking prevalence occurred among non-Hispanic White teen mothers, with lower prevalence among Hispanic and non-Hispanic Black teen mothers. Compared to other women, teenage mothers are 2.5 times as likely to smoke daily in young adulthood. Their greater likelihood of daily smoking is due in part to selection and is also mediated by socioeconomic status in ways that differ by race/ethnicity. CONCLUSIONS: The findings suggest that preventing teen pregnancy or ameliorating its socioeconomic consequences may decrease daily smoking in this vulnerable population. Reducing teen smoking, especially during pregnancy, could improve teen, maternal, and infant health and thereby increase US health and longevity. CONTRIBUTION: This study provides new, nationally representative information about selection, mediation, and heterogeneity processes in the relationship between teen childbearing and subsequent smoking.

Postmortem Presence of Drugs and Method of Violent Suicide.

The link between substance use and suicide is well established. However, little research analyzes how substance use is related to the method of suicide. This paper analyzes how specific drugs are associated with method of suicide, a critical topic because drug use bears on the etiology of suicide and may lead to policies aimed at deterring suicide. We use the COVDRS and logistic regression to examine postmortem presence of drugs among 3,389 hanging and firearm suicides in Colorado from 2004-2009. Net of demographic controls, we find that opiates are positively associated with firearms (OR: 1.92, 95% L: 1.27, 95% U: 2.86]) while antidepressants are positively associated with hanging (OR: 1.45, 95% L: 1.04, 95% U: 2.03). For cocaine and opiates, the association between drug use and violent method vary by educational attainment. Importantly, knowledge of the presence and type of specific drug is strongly associated with the method of suicide.

Cognition and Diabetes: Examining Sex Differences Using a Longitudinal Sample of Older Adults.

Objectives: This study aims to investigate sex-based differences in the diabetes status and cognition relationship using a representative sample of older Americans. Methods: Using a sample of 19,190 females and 15,580 males from the Health and Retirement Study, we conduct mixed-effects linear regression analyses to examine sex differences in the association between diabetes and cognition over a 20-year follow-up period among older adults in the United States. Main Findings: Females experience slightly steeper declines in cognition that are further exacerbated by diabetes. At age 65, females without diabetes have significantly higher cognition than males; this gap is eliminated by age 85. Among diabetics, there is no initial sex disparity, but females' cognition becomes significantly lower than males' over the following 20 years. Principal Conclusions: Relative to males, females are particularly susceptible to diabetes-related declines in cognition with increasing age.

The Enduring Association between Education and Mortality: The Role of Widening and Narrowing Disparities.

This paper examines how educational disparities in mortality emerge, grow, decline, and disappear across causes of death in the United States and how these change contribute to the enduring association of education and mortality over time. Focusing on adults age 40-64, we first examine the extent to which disparities in all-cause mortality by education persisted from 1989-2007. We then test the "fundamental cause" prediction that mortality disparities persist, in part, by shifting to new health outcomes over time, most importantly for those causes of death that have increasing mortality rates. To test this hypothesis, we focus in depth on the period from 1999-2007, when all causes of death were coded to the same classification system. The results indicate (a) both substantial widening and narrowing of mortality disparities across causes of death, (b) almost all causes of death that had increasing mortality rates also had widening disparities by education, and (c) the total disparity by education in all-cause mortality would be about 25% smaller today were it not for newly widened or emergent disparities since 1999. These results point to the theoretical and policy importance of identifying the social forces that cause health disparities to widen over time.

Education inequality in mortality: The age and gender specific mediating effects of cigarette smoking.

A debate within the mortality literature centers around the impact of health behaviors on the prospects of disadvantaged groups. Meanwhile, a growing body of work illustrates the social processes that shape changes in smoking levels by socioeconomic status (SES), especially educational attainment. These literatures are merged by examining the mediating effects of cigarette smoking on education gaps in U.S. adult mortality by age and gender. Findings reveal that cigarette smoking is an important mediator of the education-mortality gap for all males and for younger females. In particular, education-mortality gaps for young men narrow considerably when cigarette smoking is accounted for, while older women experienced no reduction in the education-mortality gap with controls for smoking. These results are consistent with diffusion arguments that describe SES differences in smoking adoption by age and gender and provide strong evidence that smoking is an important differentiator of mortality risks by education.

The Relationship Between Education and Pain Among Adults Aged 30-49 in the United States.

Pain is a major health problem among U.S. adults. Surprisingly little, however, is known about educational disparities in pain, especially among the nonelderly. In this study, we analyze disparities in pain across levels of educational attainment. Using data from the 2010 to 2017 National Health Interview Survey among adults aged 30 to 49 (N = 74,051), we estimate logistic regression models of pain prevalence using a dichotomous summary pain index and its 5 constituent pain sites (low back, joint, neck, headache/migraine, and facial/jaw). We find a significant and steep pain gradient: greater levels of educational attainment are associated with less pain, with 2 important exceptions. First, adults with a high-school equivalency diploma (GED) and those with "some college" have significantly higher pain levels than high school graduates despite having an equivalent or higher attainment, respectively. Second, the education-pain gradient is absent for Hispanic adults. After taking into account important covariates including employment, economic resources, health behaviors, physical health conditions, and psychological wellbeing, educational disparities in pain are no longer statistically significant except for the GED and "some college" categories, which still show significantly higher pain levels than high school graduates. We thus document the overall education-pain gradient in most younger U.S. adult populations, and identify groups where pain is higher than expected (certain educational categories) or lower than expected (eg, less-educated Hispanics). Understanding the causes of these anomalous findings could clarify factors shaping pain prevalence and disparities therein. PERSPECTIVE: Over 50% of U.S. adults age 30 to 49 report pain. Overall, more educated Americans report substantially less pain than the less educated. However, adults with a GED and "some college" report more pain than other groups. Understanding the causes could help illuminate the mechanisms through which social factors influence pain.

Maternal Educational Attainment and Child Health in the United States.

PURPOSE: To identify how child health status differs by mother's educational attainment for the overall US population and by race/ethnicity and to assess whether these disparities have changed from 2000 to 2017. DESIGN: Repeated cross-sectional data from the 2000-2017 National Health Interview Survey (NHIS). SETTING: United States. PARTICIPANTS: Children aged 1 to 17 years from a nationally representative sample of the noninstitutionalized US population (N = 199 427). MEASURES: Reported child health status, mother's educational attainment, child's race/ethnicity, and control variables were measured using the NHIS. ANALYSIS: Using logistic regression models, we assessed the relationship between maternal education and child health. Missing data were imputed. RESULTS: Children whose mothers had less than a high school education (odds ratio [OR] = 3.84, 95% confidence interval [CI]: 3.62-4.07), high school diploma or equivalent (OR = 2.57, 95% CI: 2.44-2.70), or some college (OR = 1.90, 95% CI: 1.80-2.00) had worse reported health status compared to children whose mothers graduated college. These associations were strongest among non-Hispanic white children, with significantly (P < .05) smaller associations observed for non-Hispanic black, Mexican origin, and other Hispanic children. The associations were smaller but persisted with inclusion of controls. From 2000 to 2017, child health disparities slightly narrowed or remained stagnant among white, non-Hispanic black, and other Hispanic children but widened for Mexican origin children (P < .05). CONCLUSION: Maternal education disparities in child health are wide and have persisted.

Lung cancer mortality among never-smokers in the United States: estimating smoking-attributable mortality with nationally representative data.

PURPOSE: Lung cancer mortality among never-smokers is an often overlooked yet important cause of adult mortality. Moreover, indirect approaches for estimating smoking-attributable mortality use never-smoker lung cancer death rates to approximate smoking burden. To date, though, most studies using indirect approaches import rates from the Cancer Prevention Study II (CPS-II), which is not representative of the U.S. METHODS: We use the nationally representative 1985-2015 National Health Interview Survey-Linked Mortality Files (NHIS-LMF) to calculate lung cancer death rates among never-smokers aged 50 years or older. We then import rates from NHIS-LMF and CPS-II into the Preston-Glei-Wilmoth indirect method to determine whether smoking-attributable fractions differ. RESULTS: Never-smokers account for 16% of U.S. lung cancer deaths among women and 11% among men. Lung cancer death rates among never-smokers are higher in NHIS-LMF than CPS-II for several age groups. Smoking-attributable fractions of mortality are slightly lower with NHIS-LMF rates (19% of male deaths and 16% of female deaths) than with CPS-II rates (21% of male deaths and 17% of female deaths). CONCLUSIONS: Fractions based on nonrepresentative CPS-II data may modestly overestimate smoking-attributable mortality. Thus, indirect methods should use never-smoker lung cancer death rates from such nationally representative datasets as NHIS-LMF.

Race/ethnicity, maternal educational attainment, and infant mortality in the United States.

This study examines patterns of and explanations for racial/ethnic-education disparities in infant mortality in the United States. Using linked birth and death data (2007-2010), we find that while education-specific infant mortality rates are similar for Mexican Americans and Whites, infants of college-educated African American women experience 3.1 more deaths per 1,000 live births (Rate Ratio = 1.46) than infants of White women with a high school degree or less. The high mortality rates among infants born to African American women of all educational attainment levels are fully accounted for by shorter gestational lengths. Supplementary analyses of data from the National Longitudinal Study of Adolescent to Adult Health show that college-educated African American women exhibit similar socioeconomic, contextual, psychosocial, and health disadvantages as White women with a high school degree or less. Together, these results demonstrate African American-White infant mortality and socioeconomic, health, and contextual disparities within education levels, suggesting the role of life course socioeconomic disadvantage and stress processes in the poorer infant health outcomes of African Americans relative to Whites.

Historical trends in height, weight, and body mass: data from U.S. Major League Baseball players, 1869-1983.

We employ a unique dataset of Major League Baseball (MLB) players - a select, healthy population - to examine trends in height, weight, and body mass in birth cohorts from 1869 to 1983. Over that 115-year time period, U.S. born MLB players have gained, on average, approximately 3 in. (7.6 cm) in height and 27.0 lb (12.2 kg) in weight, which has contributed a 1.6-unit increase in the body mass index. Where comparable data are available, U.S. born MLB players are about 2.0 in. (5.1cm) taller and 20.0 lb (9.1 kg) heavier but substantially less obese than males in the general U.S. population. But both groups exhibit similar height and weight trends; the majority of height and weight gains take place in cohorts that were born prior to World War II, followed by slower gains and occasional declines in height and weight for cohorts born in 1939 and later.

Does the Hispanic health advantage extend to better management of hypertension? The role of socioeconomic status, sociobehavioral factors, and health care access.

Hispanics in the United States (and foreign-born Hispanics in particular) have relatively favorable health given their lower socioeconomic status compared to, for example, non-Hispanic whites. This phenomenon is often called the Hispanic health paradox (HHP). This study examines whether the previously documented HHP in hypertension prevalence extends to its management using clinical and self-reported measures from the 2007-2012 National Health and Nutrition Examination Surveys. Multivariate models adjusting for demographic, socioeconomic, and sociobehavioral characteristics show an advantage among foreign-born Mexicans in hypertension prevalence relative to non-Hispanic whites (adjusted OR = 0.85). However, compared to non-Hispanic whites, foreign-born Mexicans were 38% less likely to receive treatment recommendations and, when advised to undergo treatment, were 60% less likely to adhere to treatment. Adjusting for health care access and utilization dramatically reduces disparities in hypertension control between foreign-born Mexicans and non-Hispanic whites, suggesting that insufficient systematic access to and use of quality health care erodes the HHP and contributes to the deterioration of health throughout the immigrant experience. Without appropriate interventions, particularly in health care access and utilization, poorer hypertension management among foreign-born Mexicans may negatively affect the Hispanic health profile, increase risk of cardiovascular disease-related mortality, and erode the Hispanic health advantage in the future.

Racial disparities in health conditions among prisoners compared with the general population.

This paper compares black-white health disparities among state prisoners to disparities in the noninstitutionalized community to provide a more complete portrait of the nation's heath. We use data from the 2004 Survey of Inmates in State and Federal Correctional Facilities and the 2002 and 2004 National Health and Nutrition Examination Survey for incarcerated and noninstitutionalized adult (aged 18 to 65) men and women, respectively. Health disparities between black and white male prisoners based on self-reported prevalence are similar to disparities in the general population for hypertension and diabetes but significantly reduced for kidney problems and stroke. Health disparities between black and white female prisoners are similar to disparities in the general population for obesity but significantly reduced for hypertension, diabetes, heart problems, kidney problems, and stroke. Our study reveals that prisoners report far worse health profiles than non-prisoners but there is differential health selection into prison for whites and blacks, and population health estimates for adult black men in particular are underreporting the true health burden for U.S. adults. Our findings highlight the importance of incorporating prison populations in demographic and public health analyses.
