Patterns and Life Course Determinants of Black-White Disparities in Biological Age Acceleration: A Decomposition Analysis.

Despite the prominence of the weathering hypothesis as a mechanism underlying racialized inequities in morbidity and mortality, the life course social and economic determinants of Black-White disparities in biological aging remain inadequately understood. This study uses data from the Health and Retirement Study (n = 6,782), multivariable regression, and Kitagawa-Blinder-Oaxaca decomposition to assess Black-White disparities across three measures of biological aging: PhenoAge, Klemera-Doubal biological age, and homeostatic dysregulation. It also examines the contributions of racial differences in life course socioeconomic and stress exposures and vulnerability to those exposures to Black-White disparities in biological aging. Across the outcomes, Black individuals exhibited accelerated biological aging relative to White individuals. Decomposition analyses showed that racial differences in life course socioeconomic exposures accounted for roughly 27% to 55% of the racial disparities across the biological aging measures, and racial disparities in psychosocial stress exposure explained 7% to 11%. We found less evidence that heterogeneity in the associations between social exposures and biological aging by race contributed substantially to Black-White disparities in biological aging. Our findings offer new evidence of the role of life course social exposures in generating disparities in biological aging, with implications for understanding age patterns of morbidity and mortality risks.

The Buffering Effect of State Eviction and Foreclosure Policies for Mental Health during the COVID-19 Pandemic in the United States.

The COVID-19 pandemic spurred an economic downturn that may have eroded population mental health, especially for renters and homeowners who experienced financial hardship and were at risk of housing loss. Using household-level data from the Census Bureau's Household Pulse Survey (n = 805,223; August 2020-August 2021) and state-level data on eviction/foreclosure bans, we estimated linear probability models with two-way fixed effects to (1) examine links between COVID-related financial hardship and anxiety/depression and (2) assess whether state eviction/foreclosure bans buffered the detrimental mental health impacts of financial hardship. Findings show that individuals who reported difficulty paying for household expenses and keeping up with rent or mortgage had increased anxiety and depression risks but that state eviction/foreclosure bans weakened these associations. Our findings underscore the importance of state policies in protecting mental health and suggest that heterogeneity in state responses may have contributed to mental health inequities during the pandemic.

Net worth poverty and adult health.

This study broadens the traditional focus on income as the primary measure of economic deprivation by providing the first analysis of wealth deprivation, or net worth poverty (NWP), and adult health. Net worth poverty-having wealth (assets minus debts) less than one-fourth of the federal poverty line-likely exacerbates the negative effects of income poverty (IP). In 2019, one-third of US households were net worth poor, with substantially higher rates among Black (60%) relative to White (25%) households. We estimate longitudinal growth curve (i.e., linear mixed effects) models to test how NWP, IP, and the interaction of the two predict a diverse set of health measures. We also consider whether NWP resulting from either low assets or high debts is more predictive of health outcomes and test for heterogeneous associations by race. Data come from Panel Study of Income Dynamics on 8,962 individuals ages 25 to 64, observed between 2011 and 2019 (n = 26,776). Adjusting for income poverty, net worth poverty, relative to no poverty, was associated with a one-quarter to one-third increase in the likelihood of reporting poor self-rated health, psychological distress, and work limitations. Simultaneously experiencing both NWP and IP was associated with the largest deficits. Both asset-driven (low asset) and debt-driven (high debt) NWP reduced health, but asset-driven NWP had stronger associations (e.g., a 5-percentage point increase of being in poor health, twice that of debt-driven). White, relative to Black, adults exhibited statistically larger associations for psychological distress (4.3 vs 1.1 percentage points) and work limitations (3.7 vs. 1.5 percentage points). White and Black adults who were jointly net worth and income poor exhibited the most disadvantage. Findings underscore how wealth is a critical component of financial deprivation and that wealth deprivation, particularly the lack of assets, merits attention in socioeconomic studies of health inequalities.

Vicarious Exposure to the Criminal Legal System Among Parents and Siblings.

Objective: This study documents life course patterns of vicarious exposure to the criminal legal system among parents and siblings in the United States. Background: The criminal legal system shapes family outcomes in important ways. Still, life course patterns of vicarious exposure to the system-especially to lower-level contacts-among parents and siblings are not well documented. Method: Using longitudinal data from the Panel Study of Income Dynamics, Kaplan-Meier survival curves, and Cox regression models, we estimate cumulative risks of vicarious exposure to arrest, probation, and incarceration among parents (n=3,885 parents; 185,444 person-years) and siblings (n=1,875; 44,766 person-years) and examine disparities by race-ethnicity, gender, and education, and at their intersections. Results: Vicarious exposure to the system is common-but highly unequal-among parents and siblings. Racially minoritized parents and siblings had greater levels and earlier risks of exposure. For example, by age 50, an estimated one in five Black parents experienced having a child incarcerated, a risk about twice as high as White and 50% higher than Latinx parents. By age 26, an estimated six in 10 Black young people with brothers experienced having a brother arrested; more than four in 10 experienced a brother on probation; and more than three in 10 experienced brother incarceration. For many estimates, racialized inequities in risks of vicarious system exposure widened at higher levels of education. Conclusion: These findings provide essential context for understanding the role of the criminal legal system in maintaining and exacerbating family inequality.

Racial Disparities in Mortality During the 1918 Influenza Pandemic in United States Cities.

Against a backdrop of extreme racial health inequality, the 1918 influenza pandemic resulted in a striking reduction of non-White to White influenza and pneumonia mortality disparities in United States cities. We provide the most complete account to date of these reduced racial disparities, showing that they were unexpectedly uniform across cities. Linking data from multiple sources, we then examine potential explanations for this finding, including city-level sociodemographic factors such as segregation, implementation of nonpharmaceutical interventions, racial differences in exposure to the milder spring 1918 "herald wave," and racial differences in early-life influenza exposures, resulting in differential immunological vulnerability to the 1918 flu. While we find little evidence for the first three explanations, we offer suggestive evidence that racial variation in childhood exposure to the 1889-1892 influenza pandemic may have shrunk racial disparities in 1918. We also highlight the possibility that differential behavioral responses to the herald wave may have protected non-White urban populations. By providing a comprehensive description and examination of racial inequality in mortality during the 1918 pandemic, we offer a framework for understanding disparities in infectious disease mortality that considers interactions between the natural histories of particular microbial agents and the social histories of those they infect.

Early life patterns of criminal legal system involvement: Inequalities by race/ethnicity, gender, and parental education.

BACKGROUND: Contacts with the criminal legal system have consequences for a host of outcomes. Still, early life age patterns of system involvement remain to be better understood. OBJECTIVE: We estimate cumulative risks of arrest, probation, and incarceration from childhood through early adulthood and assess disparities by race/ethnicity, gender, and parental education. METHODS: Data come from the Transition to Adulthood Supplement of the Panel Study of Income Dynamics (n = 2,736). We use Kaplan-Meier curves and Cox regression models to estimate cumulative risks of arrest, probation, and incarceration across the early life course and document disparities by race/ethnicity, gender, and parental education, as well as at their intersections. RESULTS: Criminal legal system involvement is common among recent cohorts, but Black and Latinx boys and young men face especially high risks. Among Black men whose highest-educated parent completed high school or less, an estimated six in ten had been arrested, four in ten had experienced probation, and four in ten had been incarcerated by age 26. Among Latinx men whose highest-educated parent completed high school or less, an estimated four in ten had been arrested and one in four had been incarcerated by age 26. Black women also experienced high risks, with an estimated one in four arrested by age 26. CONTRIBUTION: We document early life patterns of criminal legal system involvement among young people who came of age during the expansion of proactive policing and mass incarceration in the United States, providing important context for understanding the role of the system in generating and exacerbating life course inequalities.

Structural Racism and Quantitative Causal Inference: A Life Course Mediation Framework for Decomposing Racial Health Disparities.

Quantitative studies of racial health disparities often use static measures of self-reported race and conventional regression estimators, which critics argue is inconsistent with social-constructivist theories of race, racialization, and racism. We demonstrate an alternative counterfactual approach to explain how multiple racialized systems dynamically shape health over time, examining racial inequities in cardiometabolic risk in the National Longitudinal Study of Adolescent to Adult Health. This framework accounts for the dynamics of time-varying confounding and mediation that is required in operationalizing a "race" variable as part of a social process (racism) rather than a separable, individual characteristic. We decompose the observed disparity into three types of effects: a controlled direct effect ("unobserved racism"), proportions attributable to interaction ("racial discrimination"), and pure indirect effects ("emergent discrimination"). We discuss the limitations of counterfactual approaches while highlighting how they can be combined with critical theories to quantify how interlocking systems produce racial health inequities.

The health impacts of eviction: Evidence from the national longitudinal study of adolescent to adult health.

Eviction represents an urgent social and economic issue in the United States, with nearly two million evictions occurring annually in the U.S. Still, the population health impacts of evictions, as well as the pathways linking eviction to health, are not well documented or understood, particularly among young adults. Using nationally-representative, longitudinal data from the National Longitudinal Study of Adolescent to Adult Health (1994-2008) (n = 9029), the present study uses a combination of analytic methods-including prospective lagged dependent variable regression models, inverse probabilities of treatment weighting, longitudinal first difference models, causal mediation techniques-to comprehensively assess whether and how evictions relate to depressive risk and self-rated health across early adulthood, paying particular attention to the stress-related pathways linking eviction and health. Results provide robust evidence of positive longitudinal associations between eviction and depressive risk, in particular. In the prospective regression models, young adults who experienced recent eviction had more depressive symptoms and worse self-rated health than those who were not evicted, net a host of background characteristics. Using treatment weighting techniques, results showed that young adults who experienced eviction had more depressive symptoms than those who were not evicted (5.921 vs. 4.998 depressive symptoms, p = 0.003). Perceived social stress mediated nearly 18 percent of the associations between eviction and the depressive symptoms (p < 0.001). In the first difference models, young people who experienced eviction between survey waves experienced greater increases in depressive symptoms over time compared to those who were not evicted, net of changes in other indicators of socioeconomic status and residential instability. Taken together, our results suggest that the recent surges in evictions in the U.S. serve as a potent threat to population health during the emerging adult period, with especially devastating consequences for low-income individuals and communities of color.

"Toxic" schools? How school exposures during adolescence influence trajectories of health through young adulthood.

A large body of research identifies the critical role of early-life social contexts such as neighborhoods and households in shaping life course trajectories of health. Less is known about whether and how school characteristics affect individual health and contribute to population health inequality. However, recent scholarship argues that some school environments are so stressful due to high levels of violence, disorder, and poverty that they may be "toxic" to student health, but this hypothesis has not been tested using population data. Integrating insights from the life course perspective and stress process model, we use rich longitudinal data from the National Longitudinal Study of Adolescent to Adult Health (n = 11,382), diverse markers of physiological functioning and psychological well-being, and multilevel regression models to examine whether and how school characteristics shape trajectories of physiological dysregulation and depressive risk from adolescence through early adulthood. Findings reveal that, across multiple measures of physiological functioning and psychological well-being, the social and structural characteristics of schools play an essential role in shaping health risk from adolescence through young adulthood-long after students left school. In particular, indicators of school-level violence and perceptions of safety and school social disconnectedness had especially strong associations with health risk in both the short- and long-term. School socioeconomic composition was also strongly associated with physiological dysregulation in young adulthood, net of individual and neighborhood socioeconomic exposures. Together, findings from this study suggest that school environments can serve as early-life stressors in the lives of young people that unequally shape health trajectories and contribute to broader patterns of health inequality.

Criminal Justice Contacts and Psychophysiological Functioning in Early Adulthood: Health Inequality in the Carceral State.

Despite increased attention to the links between the criminal justice system and health, how criminal justice contacts shape health and contribute to racial health disparities remains to be better understood. Using data from the National Longitudinal Study of Adolescent to Adult Health (N = 5,488) and several analytic techniques-including a quasi-treatment-control design, treatment-weighting procedures, and mediation analyses-this study examines how criminal justice contacts shape inflammatory and depressive risk and contribute to black-white health gaps. Findings revealed that incarceration is associated with increased C-reactive protein and depressive risk, particularly for individuals who experienced long durations of incarceration. Arrests are also associated with mental health, and mediation analyses showed that racial disparities in arrests and incarceration were drivers of black-white gaps in depressive symptoms. Together, this study provides new evidence of the role of the criminal justice system in shaping health and patterning black-white health gaps from adolescence through early adulthood.

Longer-but Harder-Lives?: The Hispanic Health Paradox and the Social Determinants of Racial, Ethnic, and Immigrant-Native Health Disparities from Midlife through Late Life.

Though Hispanics live long lives, whether a "Hispanic paradox" extends to older-age health remains unclear, as do the social processes underlying racial-ethnic and immigrant-native health disparities. Using data from the Health and Retirement Study (2004-2012; N = 6,581), we assess the health of U.S.- and foreign-born Hispanics relative to U.S.-born whites and blacks and examine the socioeconomic, stress, and behavioral pathways contributing to health disparities. Findings indicate higher disability, depressive, metabolic, and inflammatory risk for Hispanics relative to whites and similar health profiles among Hispanics and blacks. We find limited evidence of a healthy immigrant pattern among foreign-born Hispanics. While socioeconomic factors account for Hispanic-white gaps in inflammation, disparities in other outcomes persist after adjustment for socioeconomic status, due in part to group differences in stress exposure. Hispanics may live long lives, but their lives are characterized by more socioeconomic hardship, stress, and health risk than whites and similar health risks as blacks.

Social Relationships, Inflammation, and Cancer Survival.

Background: Social stressors, such as social relationship deficits, have been increasingly linked to chronic disease outcomes, including cancer. However, critical gaps exist in our understanding of the nature and strength of such links, as well as the underlying biological mechanisms relating social relationships to cancer progression and survival.Methods: Utilizing novel questionnaire and biomarker data from the UNC Health Registry/Cancer Survivorship Cohort, this study examines the associations between diverse measures of social support and mortality risk among individuals with cancer (N = 1,004). We further assess the role of multiple serum markers of inflammation, including high-sensitivity C-reactive protein (CRP), IL6, TNFα, and VEGF, as potential mediators in the social relationship-cancer link.Results: The findings revealed that one's appraisal of their social support was associated with cancer mortality, such that individuals reporting higher levels of social support satisfaction had lower mortality risk than individuals reporting lower levels of satisfaction. The amount of support received, on the other hand, was not predictive of cancer survival. We further found evidence that inflammatory processes may undergird the link between social support satisfaction and mortality among individuals with cancer, with individuals reporting higher levels of social support satisfaction having lower levels of CRP, IL6, and TNFα.Conclusions: These results provide new knowledge of the biosocial processes producing population disparities in cancer outcomes.Impact: Our study offers new insights for intervention efforts aimed at promoting social connectedness as a means for improving cancer survival.

Young Adult Risk Factors for Cancer: Obesity, Inflammation, and Sociobehavioral Mechanisms.

INTRODUCTION: The paper assesses social disparities in the burdens of metabolic and inflammatory risks for cancer in the U.S. young adult population and examines psychosocial and behavioral mechanisms in such disparities. METHODS: Using data of 7,889 individuals aged 12-32 years from the National Longitudinal Study of Adolescent to Adult Health from 1994 to 2009, generalized linear models were used to assess the sex, race/ethnicity, and SES differences in the risks of obesity and inflammation, measured by C-reactive protein. Further tests examined the extent to which social isolation, smoking, physical inactivity, alcohol abuse, and illicit drug use explain social differentials in each biomarker outcome. RESULTS: Women, blacks, Hispanics, and socioeconomically disadvantaged groups had higher risks of obesity and elevated C-reactive protein, with the SES gradients being more pronounced in female participants. Health-related behaviors showed large variation across sex, race, and SES strata. After adjusting for these behavioral variables, sex, and race disparities in obesity and excess inflammation in blacks diminished, whereas the adolescent SES disparity in obesity remained. The associations of adolescent and young adult SES disadvantage and inflammation were also explained by behavioral mechanisms. Behavioral factors associated with higher risks of obesity and inflammation differed, with the exception of fast food consumption, a risk factor for both. CONCLUSIONS: This study provides new knowledge of social distribution of early life exposures to physiologic precedents to cancer development later in life with implications for prevention and early intervention of modifiable risky behaviors in adolescents and young adults.
