Interactive Effects of Chronic Health Conditions and Financial Hardship on Episodic Memory among Older Blacks: Findings from the Health and Retirement Study

Childhood and Adulthood Trauma Associate With Cognitive Aging Among Black and White Older Adults

Sociocontextual factors powerfully shape risk for age-related cognitive impairment, including excess risk burdening medically underserved populations. Lifecourse adversity associates with cognitive aging, but harms are likely mitigable. Understanding population-salient relationships and sensitive periods for exposure is crucial for targeting clinical interventions.

OBJECTIVE

The authors examined childhood and adulthood traumatic events in relation to cognition among Black and White older adults in the Health and Retirement Study (HRS).

PARTICIPANTS

Participants (N = 13,952) aged 55+ had complete lifetime trauma and cognitive testing data at the 2006/08, 2010/12, and/or 2014/16 waves.

MEASURES

Trauma indices comprised childhood and adulthood event counts. Outcomes included baseline performance and trajectories on the Telephone Interview for Cognitive Status.

DESIGN

Main and nonlinear trauma effects were modeled via linear regression, and overall contributions assessed with omnibus likelihood ratio tests.

RESULTS

Black participants (N = 2,345) reported marginally lower adulthood trauma exposure than White participants (N = 11,607) with no other exposure differentials observed. In White participants only, greater childhood trauma exposure predicted worse baseline cognition but slower change over time. Across race, adulthood trauma robustly associated with baseline cognition. Relationships were frequently nonlinear: low but nonzero trauma predicted highest cognitive scores, with much poorer cognition observed as trauma exposure increased. Relationships between adulthood trauma and trajectory were limited to the White sample.

CONCLUSION

Traumatic experiences, particularly in adulthood, may impact late-life cognitive health if not addressed. Findings highlight foci for clinical researchers and providers: adverse life events as a source of cognitive risk, and identification of community-specific resources that buffer behavioral, physical, and mental health sequelae of previous and incident trauma.

Everyday Discrimination, Neighborhood Perceptions, and Incidence of Activity Limitations Among Middle-Aged and Older African Americans

OBJECTIVES

This study aims to examine the relationship between everyday discrimination, neighborhood perceptions, and the incidence of daily activity limitations (i.e., activities of daily living [ADL] and instrumental activities of daily living [IADL]) among middle-aged and older African Americans. This study also examines whether neighborhood perceptions moderate the association between discrimination and the incidence of daily activity limitations.

METHODS

Data were from the 2006 to 2016 waves of the Health and Retirement Study. African Americans aged 50 or older free of ADL limitations (N = 1,934) and IADL limitations (N = 2,007) at baseline were selected. Cox proportional hazards regression models were performed to test the study aims. Multiple imputations were applied to handle missing data.

RESULTS

One-unit increase in everyday discrimination was associated with a 25% (p < .05) higher risk of ADL limitation onset. Perceived neighborhood social cohesion and physical disadvantage moderated the association between discrimination and IADL limitation onset.

DISCUSSION

Everyday discrimination represents a significant stressor that negatively affects older African Americans' performance of daily activities. Community-level efforts that improve neighborhood perceptions are needed to alleviate the negative effects of discrimination on the incidence of activity limitations.

Examining Racial Disparities in Historical Change of Mental and Physical Health Across Midlife and Old Age in the United States

OBJECTIVES

To examine whether racial disparities are narrowing or widening with historical time among U.S. middle-aged and older adults, and test the extent to which educational attainment moderates racial disparities over historical time.

METHODS

Multilevel models were applied to longitudinal data on middle-aged (ages 40-65) and older adults (ages 66 and older) from the Health and Retirement Study. Historical change was indexed as cohort or birth year. The outcomes of focus were depressive symptoms, episodic memory, health conditions, functional limitations, and self-rated health.

RESULTS

Results revealed a differential pattern of racial disparities in historical change between midlife and old age. Across midlife and old age, on average, Blacks and Hispanics reported poorer levels of mental and physical health, compared with Whites. In midlife, racial disparities narrowed with historical time; later-born cohorts of Hispanics but not Whites reported fewer depressive symptoms than their earlier-born peers. Likewise, historical improvements in health were stronger among Hispanics and Blacks than Whites. Conversely, in old age, later-born cohorts across race consistently showed historical improvements in each of the outcomes examined. Regarding educational attainment, we observed little consistent evidence that health-promoting effects of educational attainment differ across race and cohort. Examining questions about heterogeneity, results revealed that in midlife and old age there was greater heterogeneity between race across each of the outcomes.

DISCUSSION

Our discussion elaborates on reasons behind the documented racial differences in historical changes among U.S. middle-aged and older adults, and how the protective role of education is changing over time.

Examining the Association of Pain and Financial Hardship Among Older Men by Race in the United States

Pain associated with financial hardship among older men varies by race. The purpose of this study was to examine the association of financial hardship with the presence of pain in men 50 years and older by race. Using the Health and Retirement Study (HRS) 2010 wave, bivariate and multivariate logistic regression models were used to assess the association between four financial hardship indicators and total financial hardship as a composite score, and the presence of pain by race. Among White men, the association between the presence of pain and hardship controlling for demographic factors was statistically significant across four indicators and one composite score: ongoing financial hardship (OR = 1.29, 95% CI [1.02, 1.64]), food insecurity (OR = 2.55, 95% CI [1.51, 4.31]), taking less medication due to cost (OR = 2.12, 95% CI [1.40, 3.22]), difficulty paying bills (OR = 1.36, 95% CI [1.07, 1.73]), and total financial hardship (OR = 1.27, 95% CI [1.12, 1.44]). Among African American men, the association between the presence of pain and taking less medication due to cost (OR = 2.99, 95% CI [1.31, 6.85]) was significant. With increasing comorbidities among older adults, particularly African Americans, it is imperative to fully understand the mechanisms of this underexplored area in both the pain and financial hardship literature.
