Differences in Social Determinants of Health Underlie Racial/Ethnic Disparities in Psychological Health and Well-Being: Study of 11,143 Older Adults.

OBJECTIVE: The authors sought to determine the impact of selected social determinants of health (SDoH) on psychological health and well-being (defined as depression, cognition, and self-rated health) among Black and Hispanic/Latinx adults relative to White adults 51-89 years of age. METHODS: Disparities in depressive symptomatology, cognition, and self-rated health were measured among 2,306 non-Hispanic/Latinx Black, 1,593 Hispanic/Latinx, and 7,244 non-Hispanic/Latinx White adults who participated in the Health and Retirement Study (N=11,143). Blinder-Oaxaca decomposition was used to examine whether differences in selected SDoH explained a larger share of the disparities than age, sex, measures of health, health behaviors, and health care utilization. Selected SDoH included education, parental education, number of years worked, marital status, veteran status, geographic residence, nativity status, income, and insurance coverage. RESULTS: Black and Hispanic/Latinx adults reported worse depressive symptomatology, cognition, and self-rated health than White adults. Selected SDoH were associated with a larger proportion of the Black-White disparities in depressive symptomatology (51%), cognition (39%), and self-rated health (37%) than were age, sex, measures of health, health behaviors, and health care utilization. SDoH were associated with a larger proportion of the Hispanic/Latinx-White disparity in cognition (76%) and self-rated health (75%), but age and physical health correlated with the disparity in depressive symptomatology (28%). Education, parental education, years worked, income, and insurance parity were SDoH associated with these disparities. CONCLUSIONS: Differences in SDoH underlie racial/ethnic disparities in depression, cognition, and self-rated health among older adults. Education, income, number of years worked, and insurance parity are key SDoH.

Black Older Adults in the Age of Biomarkers, Physical Functioning, and Genomics: Heterogeneity, Community Engagement, and Bioethics.

There are persistent disparities in all-cause mortality between Blacks and Whites in the United States. Black Americans also carry the greatest burden of morbidity from different diseases of aging including heart disease, stroke, hypertension, type 2 diabetes, and certain types of cancer. Health disparities research, and particularly race/ethnic comparison studies of physical health and aging, have consistently positioned Black health in frameworks of disadvantage, suggesting that regardless of the outcome, Black people are in worse states of health and well-being relative to Whites. Yet, extensive evidence suggests that there is significant within-group variability in the aging process among Black older adults. The use of biological, physical performance, and genomic data in survey settings offer new tools and insights to interrogate heterogeneity in Black health. This chapter examines indicators of biological, physical performance, and genetic markers of aging among a national sample of Black Americans ages 54+ years with the aim of addressing two questions about heterogeneity among Black older adults: (a) How do these measures vary by age and gender among Black older adults? (b) Which indicators predict health and mortality among Black older adults? The results indicate that biological, physical performance, and genomic measures of health, generally, have more variation than simple yes or no measures of a disease, condition, or diagnosis among Black older adults, providing counternarratives to the disadvantage frameworks that dominate characterizations of Black health and aging. However, bioethical challenges limit the utility of biomarkers, physical performance, and genomics measures for Black populations.

"What Doesn't Kill You, Makes You Stronger": Psychosocial Resources and the Mental Health of Black Older Adults.

A robust body of research has shown that Black Americans are less likely than Whites to have psychiatric disorders despite the social and economic disadvantage and systemic racism that they face. This mental health paradox has been demonstrated across all ages of the life course, including older adulthood. One of the prevailing explanations for the lower prevalence of psychiatric disorders among Blacks pertains to the influence of psychosocial resources on mental health. Psychosocial resources can directly or indirectly support mental health through physiological and psychological pathways. They can also mitigate the adverse effects of social stressors of discrimination and other stressors on psychological distress and mental illness. Black older adults may particularly benefit from psychosocial resources because they have had a lifetime of experiencing and overcoming adversity. Although this cycle of stress adaptation can wear away at the physical body, it may facilitate mental health resilience. In this chapter, we review research on the relationship between psychosocial resources and mental health. The chapter begins with a brief review of the Black-White mental health paradox and the mechanisms through which psychosocial resources operate to influence mental health. We then review research on intrapersonal, interpersonal, and community-level psychosocial resources that are particularly salient for Black Americans. Throughout the chapter we highlight research specifically focused on Black older adults and discuss the cultural relevance of each resource to their mental health and psychological functioning.

Measuring More Than Exposure: Does Stress Appraisal Matter for Black-White Differences in Anxiety and Depressive Symptoms Among Older Adults?

BACKGROUND AND OBJECTIVES: Prior research and theory suggest that exposure to objectively stressful events contributes to mental health disparities. Yet, blacks report higher cumulative stress exposure than whites but lower levels of common psychiatric disorders. In order to understand why blacks bear disproportionate stress exposure but similar or better mental health relative to whites, we need to consider race differences in not only stress exposure, but also stress appraisal-how upsetting stress exposures are perceived to be. RESEARCH DESIGN AND METHODS: We examine whether race differences in the number of reported chronic stressors across 5 domains (health, financial, residential, relationship, and caregiving) and their appraised stressfulness explain black-white differences in anxiety and depressive symptoms. Data come from 6019 adults aged older than 52 from the 2006 Health and Retirement Study. RESULTS: Older blacks in this sample experience greater exposure to chronic stressors but appraise stressors as less upsetting relative to whites. In fully adjusted models, stress exposure is related to higher levels of anxiety and depressive symptoms, and perceiving stress as upsetting is associated with higher symptomology for whites and blacks. We also find that blacks report greater anxiety symptoms but fewer depressive symptoms with more stress exposure relative to whites. Stress appraisal partially explains race differences in the association between stress exposure and anxiety symptoms and fully explains race differences in the association between exposure and depressive symptoms. DISCUSSION AND IMPLICATIONS: The relationship between race, chronic stress exposure, and mental health is mediated by stress appraisal. Stress appraisal provides insight on important pathways contributing to black-white mental health disparities in older adulthood.

When Is Hope Enough? Hopefulness, Discrimination and Racial/Ethnic Disparities in Allostatic Load.

Hopefulness is associated with better health and may be integral for stress adaptation and resilience. Limited research has prospectively examined whether hopefulness protects against physiological dysregulation or does so similarly for U.S. whites, blacks and Hispanics. We examined the association between baseline hopefulness and future allostatic load using data from the Health and Retirement Study (n = 8,486) and assessed differences in this association by race/ethnicity and experiences of discrimination. Four items measured hopefulness and allostatic load was a count of seven biomarkers for which a respondent's measured value was considered high-risk for disease. A dichotomous variable assessed whether respondents experienced at least one major act of discrimination in their lifetime. We used Poisson regression to examine the association between hopefulness and allostatic load and included a multiplicative interaction term to test racial/ethnic differences in this association. Subsequent analyses were stratified by race/ethnicity and tested the interaction between hopefulness and discrimination within each racial/ethnic group. Hopefulness was associated with lower allostatic load scores, but its effects varied significantly by race/ethnicity. Race-stratified analyses suggested that hopefulness was protective among whites and not associated with allostatic load among Hispanics irrespective of experiencing discrimination. Hopefulness was associated with lower allostatic load among blacks reporting discrimination but associated with higher allostatic load among those who did not. Findings suggest that hopefulness plays differing roles for older whites, blacks and Hispanics and, for blacks, its protective effects on physiological dysregulation are intricately tied to their experiences of discrimination.

Disentangling the Stress Process: Race/Ethnic Differences in the Exposure and Appraisal of Chronic Stressors Among Older Adults.

OBJECTIVES: Exposure to stressors is differentially distributed by race/ethnicity with minority groups reporting a higher stress burden than their white counterparts. However, to really understand the extent to which some groups bear a disproportionate stress burden, we need to consider race/ethnic differences in stress appraisal, specifically how upsetting stressors may be, in addition to stress exposure. We examine racial/ethnic differences in both the number of reported chronic stressors across five domains (health, financial, residential, relationship, and caregiving) and their appraised stressfulness among a diverse sample of older adults. METHOD: Data come from 6,567 adults ages 52+ from the 2006 Health and Retirement Study. RESULTS: Results show older blacks, U.S. and foreign-born Hispanics report more chronic stress exposure than whites and are two to three times as likely to experience financial strain and housing-related stress. Socioeconomic factors fully explain the Hispanic-white difference in stress exposure, but black-white differences remain. Despite experiencing a greater number of stressors, blacks and U.S.-born Hispanics are less likely to be upset by exposure to stressors than whites. U.S.-born Hispanics are less upset by relationship-based stressors specifically, while blacks are less upset across all stress domains in fully-adjusted models. Foreign-born Hispanics are only less upset by caregiving strain. DISCUSSION: The distinction between exposure and appraisal-based measures of stress may shed light on important pathways that differentially contribute to race/ethnic physical and mental health disparities.

Do gender and racial/ethnic disparities in sleep duration emerge in early adulthood? Evidence from a longitudinal study of U.S. adults.

OBJECTIVE: Gender and racial/ethnic disparities in sleep duration are well documented among the U.S. adult population, but we know little about how these disparities are shaped during the early course of adult life, a period marked by substantial changes in social roles that can influence time for sleep. METHODS: Prospective data was used from the National Longitudinal Survey of Youth 1997 (NLSY97), a U.S.-based representative sample of persons born between 1980 and 1984, who were first interviewed in 1997. Sleep duration was assessed in 2002, 2007/2008, 2009, 2010, and 2011. Random-coefficient models were estimated to examine gender and racial/ethnic disparities in trajectories of sleep duration across early adulthood as a function of educational experiences, employment, and family relationships. RESULTS: Sleep duration declined during early adulthood. Women reported shorter sleep than men from age 18 to 22, but slept longer than men by age 28. Black Young adults reported sleep durations similar to those of White young adults until age 24, after which blacks slept less than whites. Educational experiences and employment characteristics reduced gender and racial/ethnic disparities, but family relationships exacerbated them. CONCLUSION: This study is the first to establish the emergence of gender and racial/ethnic disparities in sleep duration during early adulthood.
