Excess mortality by individual and spousal education for recent and long-term widowed

Objectives The loss of a spouse is followed by a dramatic but short-lived increase in the mortality risk of the survivor. Contrary to expectations, several studies have found this increase to be larger among those with high education. Having a spouse with high education is associated with lower mortality which suggests that losing a spouse with high education means the loss of a stronger protective factor than losing a spouse with low education. This may disproportionately affect the high educated because of educational homogamy. Methods We use Swedish total population registers to construct an open cohort of 1,842,487 married individuals aged 60 to 89 during 2007—2016, observing 239,276 transitions into widowhood and 277,946 deaths. We use Poisson regression to estimate relative and absolute mortality risks by own and spousal education among the married, recent, and long-term widows. Results We find an absolute increase in mortality risk, concentrated to the first six months of widowhood across all educational strata. The relative increase in mortality risk is larger in higher educational strata. Losing a spouse with high education is associated with higher excess mortality, which attenuates this difference. Discussion When considering the timing and the absolute level of excess mortality we find that the overall patterns of excess mortality are similar across educational strata. We argue that widowhood has a dramatic impact on health, regardless of education.

Navigating Black Aging: The Biological Consequences of Stress and Depression

Objectives Black persons in the US are more likely to suffer from social inequality. Chronic stress caused by social inequality and racial discrimination results in weathering of the body that causes physiological dysregulation and biological age being higher than chronological age (accelerated aging). Depression has been linked to both racial discrimination and accelerated aging and accelerated aging has been demonstrated to be higher in Black than White persons, on average. However, we know little about accelerated aging across the life course in Black Americans. Methods We used mixed effects growth models to measure biological age acceleration, measured with cardiometabolic markers, over a 20-year period in Black participants of the Coronary Artery Risk Development in Young Adults Study (CARDIA) who were aged 27 - 42 years at analytic baseline. We included an interaction between depressive symptoms and time to determine whether risk of depression was associated with a faster rate of biological aging. Results We found that the rate of biological aging increased over a 20-year span and that those at risk for depression had a faster rate of biological aging than those not at risk. We also found that various social factors were associated with biological age acceleration over time. Discussion Given the known association between perceived racial discrimination and depressive symptoms, we provide a novel instance of the long-term effects of social inequality. Specifically, biological age acceleration, a marker of physiological dysregulation, is associated with time among Black persons and more strongly associated among those with depressive symptoms.

Effects of Stress Exposure Versus Appraisal on Episodic Memory Trajectories: Evidence for Risk and Resilience among Black Older Adults

Objectives Chronic stressors, experienced disproportionately by Black older adults, are a risk factor for memory impairment. Racially patterned stress exposure may contribute to higher rates of Alzheimer’s disease and related dementias (ADRD) among Black older adults compared with Whites, but less is known about the role of stress appraisal. This study examined whether chronic stress exposure mediates racial disparities in memory and whether stress appraisal moderates these associations. Methods Participants included 16,924 older adults (Mage= 67.39, 21% Black) from the 2010 and 2012 waves of the Health and Retirement Study who completed measures of chronic stress exposure (health, financial, housing, relationships, and caregiving) and appraisal. Latent growth curves modeled longitudinal performance on a word list memory task over six years. Results Black older adults reported greater stress exposure than Whites, and greater stress exposure partially mediated Black-White disparities in initial memory (standardized indirect effect=–.002, p=.009). However, Black older adults appraised stressors as less upsetting than Whites. While stress appraisal did not moderate links between stress exposure and memory, appraising stressors as less upsetting was independently associated with better initial memory. Thus, Black-White disparities in initial memory was partially offset by Blacks participants' appraisal of stressors as less upsetting (standardized indirect effect=.002, p=.016). Discussion Reducing chronic stress exposure may reduce racial disparities in ADRD risk. The counteractive effect of stress appraisal on Black-White disparities in episodic memory highlights resilience factors among Black older adults that should be characterized in future research to move beyond deficit models of ADRD inequality.

Measuring Sex and Gender in Aging and Alzheimer’s Research: Results of a National Survey

Objective Differences between men and women are common in published research on aging and Alzheimer’s disease and Alzheimer’s disease and related dementias (AD/ADRD). What do these differences mean? To answer this, rigorous measurement is needed. We investigated current methods for measuring sex/gender in aging and AD/ADRD cohort studies. Method An online survey was sent to NIA-funded Alzheimer’s Disease Research Centers (ADRCs) (n=38) and investigator-initiated cohort studies (n=38) to assess practices around enrollment of men and women and measurement of sex and gender. Results The response rate was 65.8% (n=50). All enrolled men and all but two investigator-initiated studies enrolled women. Most cohorts (43/50) had no documented definitions for categories of “men” or “women”. Over 85% of cohorts relied solely on self-report questions to capture sex/gender data (n=43/50). Issues with administration were also identified (n=7). Discussion Our findings identify gaps in current approaches used to measure sex and gender in aging and AD/ADRD research. We discuss opportunities to bridge these gaps and advance measurement of sex and gender in aging and AD/ADRD research. Changes are needed to ensure inclusion and representation of sociocultural diversity in research samples, and consistency in data collection in aging and AD/ADRD research.

The Paid and Unpaid Working Life Expectancy at 50 in Europe

Objectives Amid growing concerns about the economic implications of population aging and the sustainability of older adults’ working life, unpaid family care work receives less attention despite its direct relevance to population aging. This paper systematically compares the paid and unpaid working life expectancy at age 50 to understand the overlap and trade-off between paid and unpaid work among older European adults. Method Using data from the Survey of Health and Retirement in Europe (SHARE) with the Sullivan method, the paper presents gender differences across 17 countries in life expectancy at age 50 at various paid (employment) and unpaid (caregiving) role configurations. Results When work is defined to include unpaid family caregiving, women and men have similar working life expectancies at age 50, in contrast to prior research. However, its paid and unpaid components are gendered. The results also show that at age 50, women are expected to spend similar number of years providing grandchild care and ADL/IADL care and that most of these years take place after retirement. Discussion The results highlight that the gendered tension between paid and unpaid work persists into older adulthood and needs to be accounted for in working life expectancy measures. The results also underscore the gendered implications of population aging and unpaid work in older adulthood for retirement age policies and strategies for promoting gender equality in later life.
