Race-ethnicity and health trajectories: tests of three hypotheses across multiple groups and health outcomes

'Ain't I a Nurse', implementing a digital illustration of resistance when challenging anti-Black racism in nursing education

Since the COVID-19 pandemic, ongoing reports have highlighted the urgency of addressing anti-Black racism within Canada's healthcare system. The paucity of research within a Canadian context has created growing concerns among Millennials and Generation Zs for healthcare to address growing health disparities and health inequities that are attributed to institutional and structural racism. Recognizing the paradigm shift that has occurred because of the pandemic and the sleuth of racial killings, the nursing classroom has witnessed a change and a need for nursing education to be relevant for the cohort of nursing students who are seeking answers. The scarcity of nursing literature addressing diverse forms of learning demonstrates the need for nursing education to explore new ways of being diverse, inclusive and innovative when teaching intergenerationally. In this paper, the author challenges nurse educators to revisit the student-educator relationship by introducing critical digital pedagogy to dismantle anti-Black racism and promote student-educator engagement for transformative learning to occur. As an educator, the author implements the use of digital illustration as a tool of resistance for students and educators to assess, engage, act and reflect on creating change within nursing education. Using Black feminist thought and culturally responsive learning, the author introduces an arts-based approach through the innovative design of an illustration, titled, 'Ain't I a Nurse. Combining historical stories with contemporary socio-political experiences, the author demonstrates how students and educators can enter a cognitive learning experience where they can connect mentally and emotionally, and in so doing re-envision and recreate a new world that centralizes equity, diversity and inclusivity through critical discourses. Through the illustration anti-Black racism is challenged and anti-Black racism resistance is discovered as an antidote in dismantling anti-Black racism within nursing education.

Racial-ethnic differences in the associations between functional disabilities and subsequent depression among community-dwelling midlife and older adults in the US

BACKGROUND

The intersection of race/ethnicity with disability is a critical dimension of mental health outcomes in later ages that remains under-investigated.

OBJECTIVE

We examined the role of race-ethnicity in moderating the associations between functional disabilities and subsequent depression among Americans 51 and older and stratified into the two age-groups of midlife (51-64) and older adults (≥65).

METHODS

Using a nationally representative sample of community-dwelling Americans (≥51; n = 7475) in the 2016-2018 Health and Retirement Study, we conducted bivariate and multivariable regression analyses. Racial-ethnic groups included non-Hispanic (NH) Black, Hispanic, and NH White and a binary (0/1) outcome defined subsequent depression in 2018. The total number of difficulties on the Nagi, Lawton, and Katz disability scales represented baseline (2016) functional disabilities with a secondary four-level (no/mild/severe with assistance/severe without assistance) disability indicator incorporated to examine the role of assistance with daily living.

RESULTS

Across age-groups, subsequent depression was significantly more prevalent among NH Whites with functional disabilities compared to counterparts reporting no disabilities. Compared to NH Black and Hispanic counterparts, midlife NH Whites were three times more likely to report subsequent depression with each unit increase in the functional disability score, after adjusting for covariates. However, we observed no such racial-ethnic differences among older adults. Among the 51+ severe with no assistance group, adjusted odds of subsequent depression among NH Whites was 2.5 times higher than minority counterparts.

CONCLUSION

Health programs and environmental adaptations supporting functional care needs in later ages could be beneficial for improving mental health of adults with disabilities.

The long-term consequences of school suspension and expulsion on depressive symptoms

Exposure to exclusionary discipline has been tied to several deleterious outcomes in adulthood, including contact with the criminal legal system. While this work provides interesting insight into the long-term consequences tied to this form of school punishment, few have attempted to consider whether and how, exclusionary discipline practices, in particular, school suspension and expulsion shape mental health patterning over the life course. Using panel data from the National Longitudinal Study of Adolescent to Adult Health, we contribute to this body of literature by examining whether exposure to school suspension or expulsion shapes depressive symptom trajectories from adolescence to adulthood. Results from our mixed-effects linear growth curve models demonstrate both forms of exclusionary discipline play a significant role in depressive symptom trajectories. We find suspended and expelled youth exhibit significantly higher depressive symptoms in adolescence when compared to their counterparts with no history of suspension or expulsion. Results also show age variation in depressive symptom trajectories by history of exposure to exclusionary discipline. Specifically, results show the depressive symptoms gap between disciplined and non-disciplined youth slightly dissipates as youth age into early adulthood, but as individuals begin to transition out of this stage of the life course, the gap in depressive symptoms widens substantially. Results carry implications for how punitive disciplinary practices in schools shape mental health from adolescence to adulthood.

Structural disadvantages to the kin network from intergenerational racial health inequities

This article utilizes the Panel Study of Income Dynamics to demonstrate how disadvantages in healthy life expectancies accumulated across generations create disparate kin structures among African American families in the United States. The analysis quantifies the overlap in parents' healthy years with their adult children's healthy life expectancies and examines how much the overlap coincides with the adult children's childrearing years. Non-Hispanic Black adults experienced parental illness and death sooner than non-Hispanic White adults, and their parents' poor health coincided longer with their own health declines. Non-Hispanic White adults, on the other hand, enjoyed more years in good health with two healthy parents. The intergenerational accumulation of unequal healthy life expectancies directly translated into unequal kin structures for the subsequent third generation. Race inequities in the intergenerational kin structure and health were greater among women than among men, and non-Hispanic Black women spent the most years raising children in poor health with unhealthy or deceased parents. Disparities in the intergenerational tempos of fertility, mortality, and morbidity are building profound structural racial inequities within a fundamental social institution-the family.

Racial/Ethnic Disparities in HRQoL and Associated Risk Factors in Colorectal Cancer Survivors: With a Focus on Social Determinants of Health (SDOH)

PURPOSE

This study aimed to understand how health-related quality of life (HRQoL) differs by race/ethnicity in colorectal (CRC) survivors. We aimed to 1) examine racial/ethnic disparities in HRQoL, and 2) explore the roles of social determinants of health (SDOH) risk factors for HRQoL differ by racial/ethnic groups.

METHODS

In 2,492 adult CRC survivors using Behavioral Risk Factor Surveillance System (BRFSS) survey data (from 2014 to 2021, excluding 2015 due to the absence of CRC data), we used the Centers for Disease Control and Prevention (CDC) HRQoL measure, categorized into "better" and "poor." Multivariate logistic regressions with prevalence risk (PR) were employed for our primary analyses.

RESULTS

Compared with non-Hispanic Whites (NHW), non-Hispanic Blacks (NHB) (PR = 0.61, p = .045) and Hispanics (PR = 0.32, p < .001) reported worse HRQoL in adjusted models. In adjusted models, unemployed/retired and low-income levels were common risk factors for worse HRQoL across all comparison groups (NHW, NHB, non-Hispanic other races, and Hispanics). Other SDOH associated with worse HRQoL include divorced/widowed/never married marital status (non-Hispanic other races and Hispanics), living in rural areas (NHW and NHB), and low education levels (NHB and Hispanics). Marital status, education, and employment status significantly interacted with race/ethnicity, with the strongest interaction between Hispanics and education (PR = 2.45, p = .045) in adjusted models.

CONCLUSION

These findings highlight the need for culturally tailored interventions targeting modifiable factors (e.g., social and financial supports, health literacy), specifically for socially vulnerable CRC survivors, to address the disparities in HRQoL among different racial/ethnic groups.

Drinking patterns among US men and women: Racial and ethnic differences from adolescence to early midlife

BACKGROUND

Drinking patterns among young adult men and women in the United States have been understudied, especially among racial and ethnic groups such as Asian Americans and Hispanics. Because alcohol-related racial and ethnic health disparities persist or increase in midlife, identifying peak ages of hazardous drinking could help to reduce disparities.

METHODS

We used the National Longitudinal Study of Adolescent to Adult Health to examine: (1) past 12-month heavy episodic drinking (HED) and total alcohol volume consumption among non-Hispanic White (NHW), Black, Hispanic, and Asian men and women from ages 12 through 41, and (2) age-varying associations of race and ethnicity with drinking. Hispanic and Asian ethnic groups were disaggregated by historical drinking patterns. Time-varying effect models accounted for major demographic confounders.

RESULTS

NHW men and women experienced elevated drinking rates in their early 20s, with a second elevation in their 30s. Black men and women did not have elevated drinking until their 30s. Among Hispanic men and women, peak drinking periods varied by gender and subgroup drinking pattern. Peak HED and total consumption emerged in the early 30s for Asian men, while peak HED occurred in the early 20s for Asian women. Drinking at certain ages for some racial and ethnic minoritized men and women did not differ from that in their NHW counterparts.

CONCLUSIONS

Age periods during which subgroups in the U.S. population experience elevated alcohol consumption vary by ethnicity and gender. Recognition of these group differences could enhance our understanding of intervention timing.

Employment support for Black people with long-term health conditions: a systematic narrative review of UK studies

BACKGROUND

Black people in the United Kingdom disproportionately acquire long-term health conditions and are marginalised from the labour market compared with other groups. These conditions interact and reinforce high rates of unemployment among Black people with long-term health conditions.

AIMS

To examine the efficacy, and experience, of employment support interventions in meeting the needs of Black service users in Britain.

METHODS

A systematic literature search was conducted focusing on peer-reviewed literature featuring samples drawn from the United Kingdom.

RESULTS

The literature search revealed a paucity of articles that include analysis of Black people's outcomes or experiences. Six articles met the selection criteria of the review, of which five focused on mental health impairments. No firm conclusions could be drawn from the systematic review; however, the evidence suggests that Black people are less likely than their White counterparts to secure competitive employment and that Individual Placement and Support (IPS) may be less effective for Black participants.

CONCLUSIONS

We argue for a greater focus on ethnic differences in employment support outcomes with an emphasis on how such services may remediate racial differences in employment outcomes. We conclude by foregrounding how structural racism may explain the dearth of empirical evidence in this review.

Racial/ethnic/gender-Based Differences in Health Trajectories Among American Older Adults: 10-Year Longitudinal Evidence from the Health and Retirement Study

Health disparity by race/ethnicity or gender has been well-documented. However, few researchers have examined health outcomes based on the intersection of individuals' race, ethnicity, and gender or investigated various health dimensions. Guided by an intersectionality framework, this study explores racial/ethnic/gender-based differences in trajectories of multiple health outcomes over a ten-year period among American older adults. Longitudinal data from the Health and Retirement Study (2004-2014) were used (N = 16,654). Older adults (65+) were stratified into six mutually-exclusive groups based on their race, ethnicity, and gender: Non-Hispanic (NH) White Men, NH White Women, NH Black Men, NH Black Women, Hispanic Men, and Hispanic Women. Growth curve models examined the trajectories of three health measures, including cognitive function, physical function limitations (i.e. activities of daily living and instrumental activities of daily living), and depressive symptoms. NH White men and women reported significantly better outcomes in cognition and physical function trajectories than racial/ethnic minority groups. Women in all racial/ethnic groups had more depressive symptoms but better cognition than men. Hispanic women reported the most depressive symptoms. Hispanic women and NH Black women had the worst physical function limitations. NH Black men/women were the most disadvantaged in cognition. Racial/ethnic/gender-based differences were stable over time in all health trajectories. Study findings highlight the utility of an intersectional framework in understanding how multiple social identities intersect to generate protective and/or risk effects on cognitive, mental, and physical health. Multilevel intervention strategies are warranted to reduce the persistent health inequity gap.

Involuntary delayed retirement and mental health of older adults

OBJECTIVE

This study examined the association of multiple mental health measures with involuntary delayed retirement (IDR) in working older adults (≥ 65 years) in the USA.

METHODS

Data were derived from the Health and Retirement Study, focusing on two combined waves of working older adults in 2010 and 2012. IDR was measured as the desire to stop working but the inability to do so due to financial constraints. In addition, mental health outcomes included depression, anxiety, anger-in, and anger-out. Using Stata 16.0, primary analyses were conducted for descriptive statistics and multivariable logistic regression. The odds ratios were reported with 95% confidence intervals (CIs).

RESULTS

Older adults who reported IDR were more likely to have depression (OR = 3.20, CI = 1.03-9.88), anxiety (OR = 2.12, CI = 1.00-5.18), and anger-in (OR = 1.71, CI = 1.12-2.60) compared to those who did not report IDR. However, IDR was not significantly associated with anger-out in older adults who worked past the traditional retirement age.

CONCLUSION

The findings suggest that IDR is likely to act as a stressor and affects the mental health of older adults aged 65 and more. Policymakers should pay more attention to helping older adults maintain positive mental health even if they are required to work past retirement age.

Income-Related Inequalities in Physical and Cognitive Health Domains Over the Later Life Course: Longitudinal Evidence From the U.S. (1992-2016)

This study aims to investigate changes in the income-health gradient over the later life course. We test the age-as-leveler, the cumulative advantage/disadvantage, and the persistent inequality pattern for physical and cognitive health domains, and analyze whether these patterns are gendered. We used HRS data (1992-2016) and Poisson growth curve models to predict multimorbidity (33,860 participants) as an indicator of physical health and memory (25,291 participants) as an indicator of cognitive health. We disentangled the within-participant from the between-participant effects. For multimorbidity, the income-health gradient weakened as individuals aged; whereas for memory, the income-health gradient strengthened as individuals aged. The cumulative advantage/disadvantage of higher/lower income on memory may be more pronounced among women than men. Findings were confirmed by sensitivity analyses. Findings suggest that the support for the age-as-leveler or cumulative advantage/disadvantage pattern may depend on health domains and the effect strength may depend on gender.

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.

Race and sex differences in the longitudinal changes in multidimensional self-reported sleep health characteristics in aging older adults

OBJECTIVES

We examined within-individual changes in self-reported sleep health as community-dwelling older adults age as well as potential differences in these changes by self-reported sex and racial identity.

METHODS

Participants were from the United States and enrolled in the Rush Memory and Aging Project, Minority Aging Research Study, or Religious Orders Study (N = 3539, 20% Black, 75% female, mean 78years [range 65-103]), and they received annual, in-person clinical evaluations (median 5 visits [range 1-27]). A sleep health composite score measured the number of poor sleep characteristics among satisfaction, daytime sleepiness, efficiency, and duration. Mixed effects models estimated associations of age, race, sex, and their interactions on the composite and individual sleep measures, accounting for key confounders.

RESULTS

As they aged, Black participants shifted from reporting two poor sleep characteristics to one poor sleep characteristic, while White participants shifted from one poor characteristic to two. Regardless of age, sex, and race, participants reported that they "often" felt satisfied with their sleep and "sometimes" had trouble staying asleep. Females over age 85 and males of all ages reported the most daytime sleepiness, and older White participants (>age 90) reported the most difficulty falling asleep.

CONCLUSIONS

Although self-reported sleep characteristics were typically stable across age, identifying race and sex differences in self-reported sleep health can help guide future research to understand the mechanisms that underlie these differences.

Racial and Ethnic Trajectories of Sleep Disturbances: Variations by Age and Cohort

BACKGROUND

The racial and ethnic differences in trajectories of sleep disturbances in later life are crucial for addressing health disparities, but are not well understood. This study examines (a) how trajectories of sleep disturbances vary by race and ethnicity and birth cohort and (b) whether social and health risk factors explain such variations.

METHODS

The study uses longitudinal data from the 2002-2018 Health and Retirement Study (N = 21 963) and the multilevel growth curve model to assess trajectories of sleep disturbances and their variations across 6 cohorts of White, Black, and Hispanic older adults. Sleep disturbances are measured using a modified Jenkins Sleep Scale.

RESULTS

Without controls, sleep disturbances increased with aging for all racial and ethnic groups, but more rapidly among minorities, particularly younger cohorts of Hispanic older adults. When controlling for social and health risks, sleep disturbances did not change with aging for Whites and Blacks and increased for younger cohorts of Hispanics. Cohort effects were observed among White older adults, with higher sleep disturbances in younger cohorts. Importantly, the racial and ethnic disparities in age and cohort effects were not fully explained by social and health risks. Of the symptoms, the most salient racial and ethnic disparities were found in "waking up at night" and "not feeling rested."

CONCLUSIONS

Findings reveal several differences by race and ethnicity and birth cohort in trajectories of sleep disturbances. Efforts should be made to improve sleep health for older adults as they age, especially for younger cohorts of Blacks and Hispanics.

Advancing methods for the biodemography of aging within social contexts

Several social dimensions including social integration, status, early-life adversity, and their interactions across the life course can predict health, reproduction, and mortality in humans. Accordingly, the social environment plays a fundamental role in the emergence of phenotypes driving the evolution of aging. Recent work placing human social gradients on a biological continuum with other species provides a useful evolutionary context for aging questions, but there is still a need for a unified evolutionary framework linking health and aging within social contexts. Here, we summarize current challenges to understand the role of the social environment in human life courses. Next, we review recent advances in comparative biodemography and propose a biodemographic perspective to address socially driven health phenotype distributions and their evolutionary consequences using a nonhuman primate population. This new comparative approach uses evolutionary demography to address the joint dynamics of populations, social dimensions, phenotypes, and life history parameters. The long-term goal is to advance our understanding of the link between individual social environments, population-level outcomes, and the evolution of aging.

Education and age trajectories of chronic conditions: Are tests of the cumulative advantage and disadvantage hypothesis biased by underreporting?

OBJECTIVE

This study examined the impact of underreporting on tests of the cumulative advantage and disadvantage hypothesis (CAD), which predicts age-related increases in health disparities between individuals with higher and lower education.

METHODS

Using the English Longitudinal Study of Ageing (ELSA), we identified underreporting by comparing self-reported hypertension and diabetes with biomedically measured hypertension (systolic blood pressure≥140 mm Hg and/or diastolic blood pressure≥90 mm Hg) and diabetes (fasting glucose level≥7 mmol/l and/or HbA1c≥6.5%). In a sample of 11,859 respondents aged 50 to 85 (54% women, 97% White), we assessed the associations between underreporting and the main analytic constructs in tests of the CAD (education, age, sex, and cohort).

RESULTS

The results showed that self-reported measures underestimated the prevalence of hypertension and diabetes. Underreporting showed weak to moderate associations with the main constructs in tests of the CAD, being more pronounced in individuals with lower education, in older age, in more recent cohorts, and among men. When correcting for underreporting using biomedical measures, the overall prevalence of hypertension and diabetes increased substantially, but education differences in age trajectories of both conditions remained similar.

CONCLUSIONS

Underreporting affected conclusions about the prevalence of hypertension and diabetes, but it did not affect conclusions about the CAD hypothesis for either condition.

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.

Everyday perceptions of safety and racial disparities in hair cortisol concentration

OBJECTIVE

Black-White disparities in physiological stress during adolescence are increasingly evident but remain incompletely understood. We examine the role of real-time perceptions of safety in the context of everyday routines to gain insight into the sources of observed adolescent racial differences in chronic stress as measured by hair cortisol concentration (HCC).

METHOD

We combined social survey, ecological momentary assessment (EMA), and hair cortisol data on 690 Black and White youth ages 11-17 from wave 1 of the Adolescent Health and Development in Context (AHDC) study to investigate racial differences in physiological stress. Individual-level, reliability-adjusted measures of perceived unsafety outside the home were drawn from a week-long smartphone-based EMA and tested for association with hair cortisol concentration.

RESULTS

We observed a statistically significant interaction (p < .05) between race and perceptions of unsafety. For Black youth, perceived unsafety was associated with higher HCC (p < .05). We observed no evidence of an association between perceptions of safety and expected HCC for White youth. For youth who perceive their out-of-home activity locations to be consistently safe, the racial difference in expected HCC was not statistically significant. At the high end of perceived unsafety, however, Black-White differences in HCC were pronounced (0.75 standard deviations at the 95th percentile on perceived unsafety; p < .001).

DISCUSSION

These findings call attention to the role of everyday perceptions of safety across non-home routine activity contexts in explaining race differences in chronic stress as assessed by hair cortisol concentrations. Future research may benefit from data on in situ experiences to capture disparities in psychological and physiological stress.

Racial inequality in functional trajectories between Black and White U.S. veterans

BACKGROUND

Racial inequality in functional trajectories has been well documented in the U.S. civilian population but has not been explored among Veterans. Our objectives were to: (1) assess how functional trajectories differed for Black and White Veterans aged ≥50 and (2) explore how socioeconomic, psychosocial, and health-related factors altered the relationship between race and function.

METHODS

We conducted a prospective, longitudinal analysis using the 2006-2016 Health and Retirement Study. The study cohort included 3700 Veterans who self-identified as Black or White, responded to baseline psychosocial questionnaires, and were community-dwelling on first observation. We used stepwise and stratified linear mixed effects models of biannually assessed functional limitations. The outcome measure was as a count of functional limitations. Race was measured as respondent self-identification as Black or White. Demographic measures included gender and age. Socioeconomic resources included partnership status, education, income, and wealth. Psychosocial stressors included exposure to day-to-day and major discrimination, traumatic life events, stressful life events, and financial strain. Health measures included chronic and mental health diagnoses, smoking, rurality, and use of Veterans Affairs services.

RESULTS

Black Veterans developed functional limitations at earlier ages and experienced faster functional decline than White Veterans between the ages of 50 and 70, with convergence occurring at age 85. Once we accounted for economic resources and psychosocial stressors in multivariable analyses, the association between race and the number of functional limitations was no longer statistically significant. Lower wealth, greater financial strain, and traumatic life events were significantly associated with functional decline.

CONCLUSIONS

Health systems should consider how to track Veterans' function earlier in the life course to ensure that Black Veterans are able to get timely access to services that may slow premature functional decline. Providers may benefit from training about the role of economic resources and psychosocial stressors in physical health outcomes.

The impact of hearing loss on trajectories of depressive symptoms in married couples

Hearing loss is a prevalent chronic stressor among older adults and is associated with numerous adverse health outcomes. The life course principle of linked lives highlights that an individual's stressors can impact the health and well-being of others; however, there are limited large-scale studies examining hearing loss within marital dyads. Using 11 waves (1998-2018) of the Health and Retirement Study (n = 4881 couples), we estimate age-based mixed models to examine how 1) one's own hearing, 2) one's spouse's hearing, or 3) both spouses' hearing influence changes in depressive symptoms. For men, their wives' hearing loss, their own hearing loss, and both spouses having hearing loss are associated with increased depressive symptoms. For women, their own hearing loss and both spouses having hearing loss are associated with increased depressive symptoms, but their husbands' hearing loss is not. The connections between hearing loss and depressive symptoms within couples are a dynamic process that unfolds differently by gender over time.

Association of Gulf War Illness with Characteristics in Deployed vs. Non-Deployed Gulf War Era Veterans in the Cooperative Studies Program 2006/Million Veteran Program 029 Cohort: A Cross-Sectional Analysis

Gulf War Illness (GWI), a chronic multisymptom illness with a complex and uncertain etiology and pathophysiology, is highly prevalent among veterans deployed to the 1990-1991 GW. We examined how GWI phenotypes varied by demographic and military characteristics among GW-era veterans. Data were from the VA's Cooperative Studies Program 2006/Million Veteran Program (MVP) 029 cohort, Genomics of GWI. From June 2018 to March 2019, 109,976 MVP enrollees (out of a total of over 676,000) were contacted to participate in the 1990-1991 GW-era Survey. Of 109,976 eligible participants, 45,169 (41.1%) responded to the 2018-2019 survey, 35,902 respondents met study inclusion criteria, 13,107 deployed to the GW theater. GWI phenotypes were derived from Kansas (KS) and Centers for Disease Control and Prevention (CDC) GWI definitions: (a) KS Symptoms (KS Sym+), (b) KS GWI (met symptom criteria and without exclusionary health conditions) [KS GWI: Sym+/Dx-], (c) CDC GWI and (d) CDC GWI Severe. The prevalence of each phenotype was 67.1% KS Sym+, 21.5% KS Sym+/Dx-, 81.1% CDC GWI, and 18.6% CDC GWI severe. These findings affirm the persistent presence of GWI among GW veterans providing a foundation for further exploration of biological and environmental underpinnings of this condition.

Healthy aging and late-life depression in Europe: Does migration matter?

Background

There is limited research examining the impact of risk and protective factors on late-life depression using large population-based datasets, particularly those examining differences among older migrants and non-migrants in Europe countries. Thus, the first aim was to analyze differences between migrants and non-migrants regarding socioeconomic status, depression, multimorbidity, healthy aging, and lifestyle behaviors. The second aim was to examine the impact of healthy aging on late-life depression in older migrants compared to their counterparts without a history of international migration in extensive and harmonized data from different population-based cohort studies.

Materials and methods

We analyzed cross-sectional, predominantly nationally representative, community-based data from European participants in the Aging Trajectories of Health: Longitudinal Opportunities and Synergies (ATHLOS) cohort. The descriptive analyses included sociodemographic variables, somatic comorbidities, multimorbidity, healthy aging, and lifestyle behaviors according to migration status. The effects of these variables on late-life depression were examined in a multivariate logistic regression model, including migration status and years since migration as predictors.

Results

Data of 122,571 individuals aged ≥ 50 years were analyzed, of which 11,799 (9.60%) were migrants. The descriptive analyses indicated that compared to non-migrants, migrants showed a higher prevalence of diabetes (25.6%), hypertension (38.0%), coronary artery disease (49.4%), stroke (4.9%), and depression (31.1%). Healthy aging was also better in non-migrants (51.7; SD = 9.7) than in migrants (39.6; SD = 18.2). The results of the logistic regression showed that migration status [OR = 1.231 (CIs: 0.914-1.547)] and increased number of years since migration in the host country [OR = 0.003 (CIs: 0.001-0.005)] were associated with greater levels of depressive symptoms. Concerning health variables, multimorbidity was associated with higher levels of depressive symptoms [OR = 0.244 (CIs: 0.211-0.278)], whereas better healthy aging was associated with fewer depressive symptoms [OR = -0.100 (CIs: -0.102 to -0.098)]. The interaction between migration and healthy aging status was also significant [OR. = -0.019 (CIs: -0.025 to -0.014)].

Conclusion

Migrants reported higher risks for worse health outcomes compared to non-migrants. Significantly, worse healthy aging was associated with a greater risk of depressive symptoms in migrants than in non-migrants. Shedding light on migration and aging processes is essential for promoting a cross-cultural understanding of late-life depression in Europe.

Predictors of alcohol screening quality in a US general population sample and subgroups of heavy drinkers

Alcohol screening is one of the most cost-effective clinical preventive services and important for intervening in the development of alcohol problems. We examine predictors of the quality of alcohol screening, approximated by alcohol quantity screening, which is a prerequisite for appropriate counseling, and compare conventional regression approach with Classification and Regression Trees (CART). Data come from the 2020 National Alcohol Survey, a population survey of US adults aged 18 years and over. Analyses focus on those reporting any alcohol screening at all (N = 989). The primary outcome was whether a healthcare profession had ever asked how much they drink, which is necessary to identify heavy drinking. We examined 12 potential predictors of alcohol quantity: gender, age, race and ethnicity, education, marital status, having a usual source of primary care, insurance, and health conditions. Analyses were replicated in heavy episodic drinking (HED) and high intensity drinking (HID) subgroups, both warranting alcohol counseling. Logistic regression results show that having diabetes and not having a college degree predict missed alcohol quantity screening in the sample overall, and younger age predicts missed alcohol quantity screening in the HED/HID subgroups. CART identified Black and Hispanic respondents who had not attended college at high risk of missed screening for heavy drinking in the overall sample, and those with public insurance at high risk of missed screening for heavy drinking in the HED/HID subgroups. The quality of alcohol screening needs improvement in general, and to avoid unintended disparities in alcohol-related health services.

Neighbourhood deprivation and intersectional inequalities in biomarkers of healthy ageing in England

While social and spatial determinants of biomarkers have been reported, no previous study has examined both together within an intersectional perspective. We present a novel extension of quantitative intersectional analyses using cross-classified multilevel models to explore how intersectional positions and neighbourhood deprivation are associated with biomarkers, using baseline UK Biobank data (collected from 2006 to 2010). Our results suggest intersectional inequalities in biomarkers of healthy ageing are mostly established by age 40-49, but different intersections show different relationships with deprivation. Our study suggests that certain biosocial pathways are more strongly implicated in how neighbourhoods and intersectional positions affect healthy ageing than others.

Assessing the Validity of Self-rated Health Across Ethnic Groups: Implications for Health Disparities Research

OBJECTIVES

This study examines the association between morbidity (i.e., chronic health conditions) and self-rated health (SRH) with the aim of testing the within-group and across-group validity of SRH across nine ethnic groups: non-Latinx White, Mexican, Puerto Rican, Cuban, African American, Afro-Caribbean, Chinese, Filipino, and Vietnamese Americans. In addition, we assess whether acculturation (i.e., nativity, years of US residency, language of interview) and health-related factors (e.g., mental disorder) account for ethnic distinctions in SRH.

DESIGN

Data are from the National Survey of American Life (NSAL) and the National Latino and Asian American Study (NLAAS) (N = 8338). Weighted proportions and means for SRH and chronic conditions are reported. Ordered logistic regression analysis is used to determine ethnic group patterns in SRH.

RESULTS

Despite evidence of within-group validity of SRH for each ethnic group, our results seriously challenge the across-group validity of SRH. For example, Chinese and Vietnamese respondents report lower SRH despite having fewer chronic conditions relative to non-Latinx Whites. Moreover, Mexican Americans report fewer chronic health problems but lower SRH compared to non-Latinx Whites. Acculturation factors (e.g., language of interview) partially explain the Mexican-White difference in SRH. Among Chinese Americans, completing an interview in English is associated with higher SRH relative to those who completed an interview in Chinese.

CONCLUSION

These findings have implications for health disparities research that uses SRH as the dependent measure. Studies that compare the health profiles of diverse ethnic groups should use the SRH measure with caution, as SRH does not align with ethnic patterns of morbidity.

The Association Between Educational Attainment and Mortality: Examining Absolute and Relative Effects by Race/Ethnicity

OBJECTIVES

To determine whether the association between educational attainment and mortality varies by race/ethnicity on the absolute and relative scales, including among understudied races/ethnicities.

METHODS

Data were obtained from the US National Longitudinal Mortality Study (1983-1984). Hazard models for adults aged ≥25 years (n=725,756) with race/ethnicity by educational interaction terms were used to test relative interaction; linear binomial models were used to test for absolute interaction.

RESULTS

For the most part, educational gradients in mortality did not differ across race/ethnicity on the multiplicative scale. Conversely, additive interactions appear to be significant. Blacks gained more in terms of reduced mortality rates for each additional year of schooling. The educational gradient in Whites is also notable as the lowest educated Whites have similar absolute numbers of expected deaths as Blacks similarly educated. At higher levels of education, Whites gain substantially in terms of longer longevity. The educational gradient in Asians, Hispanics, and Native Americans is narrower compared to both Whites and Blacks.

CONCLUSIONS

The association between educational attainment and mortality does not function uniformly across race/ethnicity.

Associations Between Midlife Functional Limitations and Self-Reported Health and Cognitive Status: Results from the 1998-2016 Health and Retirement Study

BACKGROUND

Life-course approaches to identify and help improve modifiable risk factors, particularly in midlife, may mitigate cognitive aging.

OBJECTIVE

We examined how midlife self-rated physical functioning and health may predict cognitive health in older age.

METHODS

We used data from the Health and Retirement Study (1998-2016; unweighted-N = 4,685). We used survey multinomial logistic regression and latent growth curve models to examine how midlife (age 50-64 years) activities of daily living (ADL), physical function, and self-reported health affect cognitive trajectories and cognitive impairment not dementia (CIND) and dementia status 18 years later. Then, we tested for sex and racial/ethnic modifications.

RESULTS

After covariates-adjustment, worse instrumental ADL (IADL) functioning, mobility, and self-reported health were associated with both CIND and dementia. Hispanics were more likely to meet criteria for dementia than non-Hispanic Whites given increasing IADL impairment.

CONCLUSION

Midlife health, activities limitations, and difficulties with mobility are predictive of dementia in later life. Hispanics may be more susceptible to dementia in the presence of midlife IADLs. Assessing midlife physical function and general health with brief questionnaires may be useful for predicting cognitive impairment and dementia in later life.

Is the Black-White mental health paradox consistent across age, gender, and psychiatric disorders?

OBJECTIVES

The Black-White mental health epidemiological paradox (i.e. Black Americans' lower or similar rates of mental disorder relative to Whites) characterizes the literature on race and mental health. Yet, research has generally paid less attention to how such findings may vary across other social statuses that shape mental health. This study assessed whether the Black-White paradox is consistent across gender, age groups, and psychiatric disorders, including lifetime mood, anxiety, and substance use disorders.

METHOD

We used data from the National Comorbidity Survey-Replication (NCS-R) and National Survey of American Life (NSAL), 2001-2003 (N = 4,591 African Americans; 6,668 non-Hispanic Whites). Psychiatric disorders were measured with the World Mental Health Survey Initiative version of the WHO Composite International Diagnostic Interview (WMH-CIDI). Binary logistic regression models were conducted to assess racial patterns of lifetime mental disorders across age and gender. Wald tests were performed to assess age and gender group differences in Black-White patterns of mental disorder.

RESULTS

The Black-White mental health paradox generally extends across lifetime mood, anxiety, and substance use disorders and is consistent across age and gender groups. One exception is middle-aged (45-64 years) Black men, who had higher odds of lifetime substance use disorder relative to their White male middle-aged peers. This difference is no longer statistically significant after accounting for education and employment. We also found more similarity in mental disorders between older Blacks and Whites relative to their younger counterparts, suggesting that Black-White mental health differences are most pronounced among younger age groups.

CONCLUSION

Our findings contribute to the broader literature on the Black-White mental health paradox by demonstrating that this epidemiological pattern persists across various mental disorder types and, at times, depends on age group and gender. Given that Black-Whte differences are less pronounced among older adults, future research should consider the ways life course theory might inform our understanding of the paradox. Findings also suggest that substance use services are critical to address the needs of middle-aged Black men of lower socioeconomic status who are disproportionately affected by substance use disorder, yet have relatively lower mental health care utilization rates.

Health Patterns among Migrant and Non-Migrant Middle- and Older-Aged Individuals in Europe-Analyses Based on Share 2004-2017

INTRODUCTION

European populations are becoming older and more diverse. Little is known about the health differences between the migrant and non-migrant elderly in Europe. The aim of this paper was to analyse changes in the health patterns of middle- and older-aged migrant and non-migrant populations in Europe from 2004 to 2017, with a specific focus on differences in age and gender. We analysed changes in the health patterns of older migrants and non-migrants in European countries from 2004 to 2017.

METHOD

Based on data from the Survey of Health, Ageing and Retirement in Europe (6 waves; 2004-2017; n = 233,117) we analysed three health indicators (physical functioning, depressive symptoms, and self-rated health). Logistic regression models for complex samples were calculated. Interaction terms (wave * migrant * gender * age) were used to analyse gender and age differences and the change over time.

RESULTS

Middle- and older-aged migrants in Europe showed significantly higher rates of depressive symptoms, lower self-rated health, and a higher proportion of limitations on general activities compared to non-migrants. However, different time trends were observed. An increasing health gap was identified in the physical functioning of older males. Narrowing health gaps over time were observed in women.

DISCUSSION

An increasing health gap in physical functioning in men is evidence of cumulative disadvantage. In women, evidence points towards the hypothesis of aging-as-leveler. These different results highlight the need for specific interventions focused on healthy ageing in elderly migrant men.

Racial Differences in Early Parental Death, Midlife Life Problems, and Relationship Strain With Adult Children

OBJECTIVES

Black Americans typically experience the death of a parent earlier in the life course than do non-Hispanic Whites, and early parental death is known to hinder subsequent relationship outcomes. Whether early parental death may contribute to racial differences in midlife family relationships and the role midlife adults' current life problems play remain unexplored.

METHOD

Using multilevel modeling, we examined how timing of parental death is associated with relationship strain with adult children and whether the association differs by midlife adults' life problems in Black (n = 166) and non-Hispanic White (n = 467) families from the Family Exchanges Study.

RESULTS

Losing a parent in childhood was associated with more relationship strain with adult children for Black midlife adults, but not for their non-Hispanic White counterparts. Among the bereaved, earlier timing of parental death was associated with more relationship strain with adult children only for Black midlife adults. In both bereaved and nonbereaved sample, participants' recent physical-emotional problems exacerbated the link between timing of parental death and relationship strain with adult children for Black midlife adults.

DISCUSSION

Experiencing the death of a parent in the early life course can be an added structural disadvantage that imposes unique challenges for Black Americans in midlife. Policies and programs aimed at supporting bereaved children may benefit relationships with their own children later in life, and addressing physical-emotional problems in midlife may be a viable intervention point for those midlife adults who experienced the death of a parent in the early life course.

Black-White disparities in women's physical health: The role of socioeconomic status and racism-related stressors

Black women have elevated rates of multiple physical illnesses and conditions when compared to White women - disparities that are only partially explained by socioeconomic status (SES). Consequently, scholars have called for renewed attention to the significance of racism-related stress in explaining Black-White disparities in women's physical health. Drawing on the biopsychosocial model of racism as a stressor and the intersectionality perspective, this study examines the extent to which SES and racism-related stressors - i.e., discrimination, criminalization, and adverse neighborhood conditions - account for disparities in self-rated physical health and chronic health conditions between Black and White women. Results indicate that Black women have lower SES and report greater exposure to racism-related stressors across all domains. Moreover, I find that SES and racism-related stressors jointly account for more than 90% of the Black-White disparity in women's self-rated physical health and almost 50% of the Black-White disparity in chronic health conditions. Theoretical and policy implications of these findings are discussed.

Black-White racial health disparities in inflammation and physical health: Cumulative stress, social isolation, and health behaviors

Black Americans have vastly increased odds and earlier onsets of stress- and age-related disease compared to White Americans. However, what contributes to these racial health disparities remains poorly understood. Using a sample of 1577 older adults (32.7% Black; ages 55-65 at baseline), we examined whether stress, health behaviors, social isolation, and inflammation are associated with racial disparities in self-reported physical health. A latent cumulative stress factor and unique stress-domain specific factors were modeled by applying bifactor confirmatory analysis to assessments across the lifespan (i.e., childhood maltreatment, trauma exposure, discrimination, stressful life events, and indices of socioeconomic status). Physical health, health behavior, and social isolation were assessed using self-report. Interleukin-6 (IL-6) and C-reactive protein (CRP) were assayed from morning fasting serum samples; a z-scored inflammation index was formed across these 2 cytokines. A parallel serial mediational model tested whether race (i.e., Black/White) is indirectly associated with health through the following 3 independent pathways: (1) cumulative stress to preventative health behaviors (e.g., healthy eating) to inflammation, (2) cumulative stress to risky health behaviors (e.g., substance use) to inflammation; and (3) cumulative stress to social isolation to inflammation. There were significant indirect effects between race and self-reported physical health through cumulative stress, preventative health behaviors, and inflammation (B = -0.02, 95% CI: -0.05, -0.01). Specifically, Black Americans were exposed to greater cumulative stress, which was associated with reduced engagement in preventative health behaviors, which was, in turn, associated with greater inflammation and reduced physical health. A unique SES factor also indirectly linked race to physical health through preventative health behaviors. Cumulative stress exposure and unique aspects of socioeconomic status are indirectly associated with Black-White racial health disparities through behavioral (i.e., preventative health behavior) and biological (i.e., inflammation) factors. Culturally responsive evidence-based interventions that enhance engagement in preventative health behaviors are needed to directly confront health disparities. Ultimately, large scale anti-racist public policies that reduce cumulative stress burden (e.g., a living wage, universal healthcare) may best attenuate racial health disparities.

The association of workplace health education with smoking-related behaviour and unequal gains by job position in China: ABWMC programme findings

Background

Although the Chinese government has introduced a series of regulations to promote tobacco-related health education in workplaces, their implementation has been far from satisfactory. The aim of the present study was to explore the association of company-level tobacco-related health education and employee smoking behaviour.

Methods

Data from the 2018 Asia Best Workplace Mainland China programme were used to address these aims. This was a cross-sectional study that included 14,195 employees from 79 companies in mainland China. Spearman correlation tests were used to examine unadjusted correlations between the study variables, and binary logistic regression was used for multivariable analysis. The dependent variables included smoking-related variables or health information-seeking behaviour. The explanatory variable was the company-level tobacco-related health education.

Results

Tobacco-related health education was associated with better smoking harm awareness (OR = 2.23; 95% CI = 1.94–2.56), lower second-hand smoke exposure (OR = 0.73; 95% CI = 0.66–0.81), better perception of the workplace environment (OR = 2.04; 95% CI = 1.84–2.26) and positive health information-seeking behaviour (OR = 2.07; 95% CI = 1.86–2.30). Job position interacted with health education, suggesting that the positive association of health education was lower for general employees than employees who held an administrative position.

Conclusions

Tobacco-related health education is not only associated with lower SHS exposure but also related to more positive environmental perceptions and health attitudes, and these effects are significant for higher-ranking employees. Policy makers should recognize and reduce these potential health disparities.

Deaths, Disparities, and Cumulative (Dis)Advantage: How Social Inequities Produce an Impairment Paradox in Later Life

BACKGROUND

Research on health across the life course consistently documents widening racial and socioeconomic disparities from childhood through adulthood, followed by stabilization or convergence in later life. This pattern appears to contradict expectations set by cumulative (dis)advantage (CAD) theory. Informed by the punctuated equilibrium perspective, we examine the relationship between midlife health and subsequent health change and mortality and consider the impact of earlier socioeconomic exposures on observed disparities.

METHODS

Using the Health and Retirement Study, we characterize the functional impairment histories of a nationally-representative sample of 8,464 older adults between 1994-2016. We employ non-parametric and discrete outcome multinomial logistic regression to examine the competing risks of mortality, health change, and attrition.

RESULTS

Exposures to disadvantages are associated with poorer functional health in midlife and mortality. However, a higher number of functional limitations in midlife is negatively associated with the accumulation of subsequent limitations for white men and women and for Black women. The impact of educational attainment, occupation, wealth, and marriage on later life health differs across race and gender groups.

CONCLUSIONS

Observed stability or convergence in later-life functional health disparities is not a departure from the dynamics posited by CAD, but rather a result of the differential impact of racial and socioeconomic inequities on mortality and health at older ages. Higher exposure to disadvantages and a lower protective impact of advantageous exposures lead to higher mortality among Black Americans, a pattern which masks persistent health inequities later in life.

Life-course trajectories of body mass index from adolescence to old age: Racial and educational disparities

No research exists on how body mass index (BMI) changes with age over the full life span and social disparities therein. This study aims to fill the gap using an innovative life-course research design and analytic methods to model BMI trajectories from early adolescence to old age across 20th-century birth cohorts and test sociodemographic variation in such trajectories. We conducted the pooled integrative data analysis (IDA) to combine data from four national population-based NIH longitudinal cohort studies that collectively cover multiple stages of the life course (Add Health, MIDUS, ACL, and HRS) and estimate mixed-effects models of age trajectories of BMI for men and women. We examined associations of BMI trajectories with birth cohort, race/ethnicity, parental education, and adult educational attainment. We found higher mean levels of and larger increases in BMI with age across more recent birth cohorts as compared with earlier-born cohorts. Black and Hispanic excesses in BMI compared with Whites were present early in life and persisted at all ages, and, in the case of Black-White disparities, were of larger magnitude for more recent cohorts. Higher parental and adulthood educational attainment were associated with lower levels of BMI at all ages. Women with college-educated parents also experienced less cohort increase in mean BMI. Both race and education disparities in BMI trajectories were larger for women compared with men.

Why Have Sleep Problems in Later-Midlife Grown Following the Great Recession? A Comparative Cohort Analysis

OBJECTIVES

This research compares three cohorts of individuals in their fifth decade of life and examines whether sleep problems are greater in cohorts following the Great Recession. We argue that these differences will occur because postrecession cohorts are exposed to more economic burdens that harm sleep. We also suggest that postrecession exposure to economic burdens will be amplified among women, leading to greater cross-cohort differences in sleep problems.

METHOD

Data were derived from the Health and Retirement Study, focusing on cohort surveys starting in 2004, 2010, and 2016 (N = 12,129). Structural equation models compared cohorts in latent levels of sleep problems and also examined whether economic burdens mediated cohort differences. Interactions tested whether cohort differences varied between men and women.

RESULTS

The 2010 and 2016 cohorts had higher mean levels of sleep problems than the 2004 cohort. Greater postrecession exposure to economic burdens largely explained inter-cohort change in sleep problems, with this pattern stronger among women.

DISCUSSION

Americans are approaching their senior years increasingly burdened by economic stressors that incur sleep problems. Practitioners and aging researchers should be prepared to address deleterious health consequences created by heightened sleep impairments.

Life Course Stressors and Functional Limitations in Later Life among White, Black, and Hispanic Adults: Deleterious, Hardening, or Benign?

OBJECTIVES

Although striking racial and ethnic disparities in health are manifest during later life, they may be rooted in early-life exposures. Drawing from cumulative inequality theory, we investigate whether life course stressors are associated with risk of later life functional limitations and whether this relationship differs by race and ethnicity.

METHODS

We utilize longitudinal data from the Health and Retirement Study to test whether child and adult stressors predict trajectories of the occurrence and severity of functional limitations among a diverse sample of older adults.

RESULTS

Child and adult stressors are associated with greater occurrence and severity of functional limitations during later life. Mediation analyses reveal the indirect influence of child stressors via adult stressors on occurrence and severity of functional limitations; however, the indirect effects are slightly stronger for Black and Hispanic adults than their White counterparts.

DISCUSSION

Child stressors, in and of themselves, do not increase functional limitations among Black and Hispanic people but are associated with greater adult stress exposure, predisposing them to more functional limitations. Results suggest that childhood stressors are associated with distinct social pathways to functional limitations among Black, White, and Hispanic older adults.

Cumulative Inequality at the End of Life?: Racial Disparities in Impairment in the Time Before Death

OBJECTIVES

Drawing from cumulative inequality (CI) theory, the current study examined racial disparities in impairment as individuals approached death to determine whether proposed mechanisms hypothesized to fuel or diminish racial disparities at late ages were at work at the end of individualized life spans.

METHOD

Black-white disparities were analyzed among decedents using latent growth curves based on the data from the North Carolina Established Populations for Epidemiologic Studies of the Elderly (EPESE) (N = 1,926).

RESULTS

Consistent with previous literature, racial inequalities in functional disparities diminish at late ages. However, significant black-white disparities emerge as older adults approach death, exponentially increasing within the 2 years immediately preceding death. Further, these disparities are not fully mediated by socioeconomic status.

DISCUSSION

The results confirm that CI in health outcomes is observable in late life among individual life spans, suggesting the years surrounding death may be a particularly vulnerable period for health inequality. Future research should examine how advantaged statuses translate to increased access to health-related resources that aid in maintaining greater functional independence until the last stage of life.

The Roles of Marital Dissolution and Subsequent Repartnering on Loneliness in Later Life

OBJECTIVES

Loneliness in later life is associated with poorer health and higher risk of mortality. Our study assesses whether gray divorced adults report higher levels of loneliness than the widowed and whether social support or repartnership offset loneliness.

METHOD

Using data from the 2010 and 2012 Health and Retirement Study, we estimated ordinary least squares regression models for women (n = 2,362) and men (n = 1,127) to examine differences in loneliness by dissolution pathway (i.e., divorce versus widowhood), accounting for social support and repartnership.

RESULTS

Divorced men were lonelier than their widowed counterparts. Although social support reduced loneliness among men, the difference between the divorced and widowed persisted. Repartnership assuaged men's loneliness and reduced the variation between divorced and widowed men. Among women, the results did not reveal differences in loneliness for the divorced and widowed although social support and repartnership linked to less loneliness.

DISCUSSION

Later-life marital dissolutions increasingly occur through divorce rather than spousal death. Some older adults go on to form new partnerships. Our findings demonstrate the importance of gerontological research widening the lens beyond widowhood to consider the ramifications of later-life divorce and repartnership for well-being.

Allostatic Load Among U.S.- and Foreign-Born Whites, Blacks, and Latinx

INTRODUCTION

The objective of this study is to examine how allostatic load, a multidimensional measure of the body's cumulative response to stressors experienced throughout the life course, has changed over time and by age among U.S.- and foreign-born Whites, Blacks, and Latinx.

METHODS

Data were from 26,818 adult participants in the 2005-2018 National Health and Nutrition Examination Survey, a national repeated cross-sectional study. Allostatic load was measured based on 10 indicators of cardiovascular, metabolic, and immunologic risk. The analyses were conducted in March 2020.

RESULTS

Allostatic load increased over time across all groups. The difference between the first and last survey cycle was greatest among U.S.-born Black women (from 2.74 in 2005-2006 to 3.02 in 2017-2018), U.S.-born Latino men (from 2.69 to 3.09) and foreign-born Latino men (from 2.58 to 2.87). Aging gradients in allostatic load were steepest among foreign-born Blacks of both genders and foreign-born Latina women and flattest among U.S.-born and foreign-born Whites.

CONCLUSIONS

Chronic exposure to stressors leads to an erosion of health that is particularly severe among foreign-born Blacks and Latinx. Policies should seek to reduce exposure to structural and environmental risks and to ensure equitable opportunities to achieve optimal health among racial/ethnic minorities and immigrants.

Inter-Individual Variability in Trajectories of Functional Limitations by Race/Gender

OBJECTIVE

Several theories emphasize that systematic interindividual divergence is a key feature of cohort aging and evidence for accumulative social inequality over the life course. While many have documented widening health gaps with age between subgroups, such divergence is only one aspect of the broader social inequality based on race and gender. This article examines patterns of interindividual variability in trajectories of functional limitations within each race/gender.

METHODS

Using data from the Health and Retirement Study (HRS)'s HRS cohort (born 1931-1941), I estimate growth curves of functional limitations with Level 2 heteroscedasticity, allowing interindividual variability to differ across 4 groups: white men, black men, white women, and black women. I examine race/gender differences in the age-based pattern of interindividual variability using an interquartile range of estimated individual trajectories.

RESULTS

Black men, white women, and black women have greater interindividual variability in functional limitations than do white men. Interindividual variability increases systematically with age at similar rates for all groups but black women.

DISCUSSION

Functional limitations become more heterogeneous with age for the entire cohort and for white men, white women, and black men. Future research should identify life-course processes that generate the race and gender patterning of interindividual variability in late-life health.

Putting cumulative (dis)advantages in context: Comparing the role of educational inequality in later-life functional health trajectories in England and Germany

BACKGROUND

The cumulative (dis)advantage (CAD) perspective more and more is examined in a comparative way, to highlight the role of context in generating inequality over the life course. This study adds to this field of research by examining trajectories of activities of daily living (ADL) in later life by educational level in a country comparison of England and Germany, emphasizing differing institutional conditions.

METHOD

Data used are the English Longitudinal Study of Ageing (ELSA; 11,352 individuals) and the German subsample of the Survey of Health and Retirement in Europe (SHARE; 5,573 individuals). Using population averaged Poisson panel regression models, 12-year trajectories of six birth cohorts are investigated, covering the age range of 50 to 90 years.

RESULTS

Respondents in England have a higher level of limitations at age 50, and more limited increases over age than in Germany. An educational gradient exists in both countries at age 50. Notably, the educational gradient increases for more recently born cohorts, but declines with increasing age in England, while in Germany educational differences increase for more recently born cohort only.

DISCUSSION

The current study indicates that CAD processes between educational groups are context sensitive. While England showed convergence of disparities with increasing age, in Germany no differential development was found.

The Relationship Between Childhood Circumstances and Late Life Physical and Mental Health: The Role of Adult Socioeconomic Status

OBJECTIVES

Socioeconomic status and health in childhood are linked to health outcomes in later life. Health outcomes may also be shaped by socioeconomic circumstances in adulthood and later life. This paper examined the relationship between childhood conditions and later life health and tested whether this relationship was mediated by later life economic living standards.

METHODS

Data from a longitudinal study of aging was combined with retrospective life history data from 787 participants from the New Zealand Health, Work and Retirement Study.

RESULTS

Significant relationships were found between childhood conditions and later life health. These relationships were mediated by economic living standards in older age, but the partial direct effect of childhood conditions on health found in early older age became fully meditated 10 years later.

CONCLUSION

While childhood circumstances are part of this complex relationship, socioeconomic conditions in later life are vital to ensuring ongoing health into older age.

Budgetary Consequences of High Medical Spending Across Age and Social Status: Evidence from the Consumer Expenditure Surveys

BACKGROUND AND OBJECTIVES

This study examines high medical spending among younger, midlife, and older households.

RESEARCH DESIGN AND METHODS

We investigate high medical spending using data from the 2010 through March 2018 Consumer Expenditures Surveys (n = 92,951). We classify and describe high medical spenders relative to others within three age groups (household heads age 25-44, 45-64, and 65+) using finite mixture models and multinomial logistic regression, respectively. We then use hierarchical linear models to estimate the effects of high medical spending on nonmedical spending.

RESULTS

Among younger households, high medical spending is positively associated with higher education and increased spending on housing and food. Among older households, high medical spending is associated with lower education and decreased nonmedical spending.

DISCUSSION AND IMPLICATIONS

Earlier in the life course, high medical spending is more likely to indicate an investment in future household well-being, while at older ages, high medical spending is likely to indicate medical consumption.

Alcohol-Related Disparities Among Women: Evidence and Potential Explanations

Although research on alcohol-related disparities among women is a highly understudied area, evidence shows that racial/ethnic minority women, sexual minority women, and women of low socioeconomic status (based on education, income, or residence in disadvantaged neighborhoods) are more likely to experience alcohol-related problems. These problems include alcohol use disorder, particularly after young adulthood, and certain alcohol-related health, morbidity, and mortality outcomes. In some cases, disparities may reflect differences in alcohol consumption, but in other cases such disparities appear to occur despite similar and possibly lower levels of consumption among the affected groups. To understand alcohol-related disparities among women, several factors should be considered. These include age; the duration of heavy drinking over the life course; the widening disparity in cumulative socioeconomic disadvantage and health in middle adulthood; social status; sociocultural context; genetic factors that affect alcohol metabolism; and access to and quality of alcohol treatment services and health care. To inform the development of interventions that might mitigate disparities among women, research is needed to identify the factors and mechanisms that contribute most to a group's elevated risk for a given alcohol-related problem.

Joint trajectories of cognition and gait speed in Mexican American and European American older adults: The San Antonio longitudinal study of aging

OBJECTIVES

Cognitive decline and gait speed slowing are independent predictors of disability and mortality. While both factors increase in prevalence with advancing age, little is known about their combined patterns of change. The study goal was to identify joint trajectories of cognition and gait speed within an aging bi-ethnic cohort of Mexican Americans and European Americans.

METHODS/DESIGN

Participants included 182 Mexican Americans and 188 European Americans, ages 65 to 74, who were followed over a mean of 9.5 years. Cognition was assessed with the mini-mental state examination and gait speed was examined with a timed 10-ft walk. Joint trajectory classes of cognition and gait speed were identified with latent growth mixture modeling. Odd-ratios assessed predictors for trajectory classes.

RESULTS

Three latent trajectory classes were identified: (a) relatively stable cognition and gait (termed stable cognition and gait class, 65.4%); (b) deteriorating cognition and gait (termed cognitive and physical vulnerability class, 22.2%); (c) stable cognition and deteriorating gait (termed physical vulnerability class, 12.4%). The odds of classification in the cognitive and physical vulnerability class vs stable cognition and gait class was associated with Mexican American ethnicity (OR = 3.771, P = .016), age (OR = 1.186, P = .017), income (OR = 0.828, P = .029), education (OR = 0.703, P < .001), and diabetes (OR = 4.547, P = .010). The odds of classification in the physical vulnerability class was associated with female sex (OR = 6.481, P = .004) and body mass index (OR = 1.118, P = .025).

CONCLUSIONS

The trajectories of cognition and gait speed were generally parallel, suggesting the two domains may act synergistically to shape important health outcomes. Socioeconomic disparities and Mexican American ethnicity independently conferred risk for accelerated decline.
