Objectives: This study aims to establish the effects of ACEs on multimorbidity through sleep quality and investigate whether lifestyle factors (e.g., eating habits and exercise) may influence this relationship among middle-aged and older adults.

Methods: Participants were drawn from a cross-sectional sample of community dwelling older adults (N = 276, 55+) and three waves of data from the Midlife in the United States study (MIDUS, N = 843). We examined the direct and indirect effects of ACEs, sleep quality, and health conditions, as well as the conditional effects of physical activity and eating habits.

Results: Across both samples, sleep quality mediated the relationship between ACEs and chronic health conditions. Moderating effects of unhealthy eating and physical activity differed between samples.

Discussion: Sleep quality is an important pathway connecting ACEs and adult multimorbidity, and health behaviors may provide targets for intervention particularly in older adults.

Objectives: This study examines whether perceived neighborhood characteristics relate to pain outcomes among middle-aged and older adults. Methods: Data were from the Health and Retirement Study (2006-2014; n = 18,814). Perceived neighborhood characteristics were physical disorder, social cohesion, safety, and social ties. We fitted adjusted generalized estimating equation models to evaluate prevalence, incidence, and recovery of moderate-to-severe limiting pain 2 years later. Results: The mean age of our sample was 65.3 years; 54.6% were female and 24.2% reported moderate-to-severe limiting pain at baseline. Positive neighborhood characteristics were associated with low prevalence (e.g., prevalence ratio [PR]: .71 for disorder) and reduced incidence (e.g., PR: .63 for disorder) of moderate-to-severe limiting pain. Positive neighborhood characteristics were associated with a high recovery rate from moderate-to-severe limiting pain (e.g., PR = 1.15 for safety), though the 95% CIs for disorder and cohesion crossed the null. Discussion: Neighborhood characteristics may be important determinants in predicting pain in later life.

Objectives: This longitudinal study tests whether the Big-Five personality traits influence the changes individuals make in self-rated health (SRH) as they adjust their initial level to account for information on concurrent changes in disease burden, activities of daily living (ADLs), and pain. Methods: A bi-variate Latent Growth Curve model was fitted to data to estimate longitudinal associations between SRH and each health measure across up-to-five repeated observations, collected from the year 2006 to 2018 from 13,096 participants in the Health and Retirement Study. Results: Negative longitudinal associations between SRH and all three health reports were significantly stronger for those who are more conscientious. No significant moderation was found for the other four personality traits. Discussion: Compared to the less conscientious, highly conscientious people may assign greater importance to specific health reports when rating and revising their assessments of SRH. This moderating effect was previously tested but not supported.

Objectives: The purpose of this study was to evaluate the psychometric properties of the modified 25-item Resilience Scale (RS-25) in older adults post-hip fracture using Rasch analysis. Methods: This was a descriptive study using baseline data from the Seventh Baltimore Hip Studies (BHS-7). There were 339 hip fracture patients included in this analysis. Results: Findings suggest there was support for reliability of the measure based on person and item separation index. The INFIT and OUTFIT statistics for testing validity were all in the acceptable range indicating that each item on the modified RS-25 fits the appropriate concept. There was no evidence of Differential Item Functioning (DIF) between genders. Conclusions: This study demonstrated evidence that the modified RS-25 is a reliable and valid measure to evaluate resilience among older adults post-hip fracture and therefore can be used in this population in clinical practice and research.

Objectives: The neighborhood environment may be an important determinant of racial/ethnic disparities in cognitive function. To understand how neighborhoods are linked to cognition across racial/ethnic groups, this scoping review organizes research investigating relationships between multiple neighborhood domains and cognitive function in diverse samples of US midlife and older adults. Methods: PubMed/MEDLINE, Web of Science, and CAHL were used to extract quantitative disparities-focused studies (n = 17) that included US adults ages 50+, racial/ethnic minoritized populations, cognitive dependent variable(s), and neighborhood-level independent variable(s) published from January 2010 to October 2021. Results: Studies demonstrate variation within and between racial/ethnic groups in how neighborhood factors are associated with cognition. Economically and socially advantaged neighborhoods were associated with better cognition. Findings were mixed for built and neighborhood composition measures. Discussion: More research with greater racial/ethnic representation is needed to disentangle which aspects of the neighborhood are most salient for specific cognitive function domains across diverse populations.

Objectives: Cognitive aging is a lifelong process with implications for Alzheimer's disease and dementia. This study aims to fill major gaps in research on the natural history of and social disparities in aging-related cognitive decline over the life span. Methods: We conducted integrative data analysis of four large U.S. population-based longitudinal studies of individuals aged 12 to 105 followed over two decades and modeled age trajectories of cognitive function in multiple domains. Results: We found evidence for the onset of cognitive decline in the 4^th decade of life, varying gender differences with age, and persistent disadvantage among non-Hispanic Blacks, Hispanics, and those without college education. We further found improvement in cognitive function across 20^th century birth cohorts but widening social inequalities in more recent cohorts. Discussion: These findings advance an understanding of early life origins of dementia risk and invite future research on strategies for promoting cognitive health for all Americans.

Objectives: The current study based on the Stress Process Model investigated the impact of experiences of domestic violence on mental health as well as resilience against negative mental health outcomes among older adults in U.S. during COVID-19.

Method: Participants included 522 older adults (ages 51-80 and older) living in US at the time of the survey. Path analysis using Mplus was employed. Results:The experience of domestic violence among older adults during the pandemic was positively associated with loneliness and anxiety directly and indirectly. However, resilience acted as a protective factor between the experiences of domestic violence and anxiety. Conclusion: The experience of domestic violence may increase loneliness and anxiety among older adults during challenging times; however, resilience may weaken these negative psychological outcomes both directly and indirectly. Findings and implications are discussed.

Objectives: This study compared the caring self-efficacy between personal care attendants (PCAs) from English-speaking and non-English-speaking countries, controlling for potential sociodemographic and work-related covariates. PCAs' perceptions of their caring self-efficacy were further explored. Methods: An independent samples t-test was used to determine the mean difference in the caring self-efficacy score between the two groups. A multivariate analysis was conducted to adjust for covariates. Thematic analysis was conducted on open-ended responses. Results: The results showed that caring self-efficacy was significantly influenced by whether participants primarily spoke English at home rather than where they were born. Younger age and everyday discrimination experiences were negatively associated with caring self-efficacy. Both groups perceived that inadequate resources and experiencing bullying and discrimination reduced their caring self-efficacy. Discussion: Access to organisational resources and training opportunities and addressing workplace bullying and discrimination against PCAs, particularly younger PCAs and those from non-English-speaking backgrounds, could improve their caring self-efficacy.

Objectives: To investigate the longitudinal association of life space and neighborhood and built environment (NBE) with subjective memory among individuals 65 and older, and the mediating role of depressive symptoms, a major correlate of life space mobility, NBE, and subjective memory. Methods: We examined community-dwelling participants in the Advanced Cognitive Training for Independent and Vital Elderly study (N = 2,622, Mean age = 73.7 years, 24.9% Black) across annual assessments of up to 3 years. Results: Baseline life space and NBE were positively associated with subjective memory, and these associations were partly mediated by depressive symptoms. Over time, higher baseline life space predicted a better subjective memory as one aged. Life space was concurrently associated with subjective memory across time, mediated by concurrent depressive symptoms. Discussion: Potentially modifiable environmental factors such as life space and NBE appear to influence level and change in subjective memory as we age. Interventions supporting movement in our environments may help offset subjective memory problems, a potential early sign of dementia.

Objectives: Advance care planning (ACP) specifies decision-making surrogates and preferences for serious illness or end-of-life medical care. ACP research has largely neglected sexual minority men (SMM), a population that experiences disparities in health care and health status. Methods: We examined formal and informal ACP among SMM ages 40+ in the Multicenter AIDS Cohort Study (N = 1,071). Results: For informal ACP (50%), younger SMM and men with past cardiovascular events had greater odds of planning; single men had lower odds of planning. For formal ACP (39%), SMM with greater socioeconomic status had greater odds of planning; SMM who were younger, of racial/ethnic minority identities, who were single or in a relationship without legal protections, and who lacked a primary care home had lower odds of planning. Discussion: Findings warrant further exploration of both informal and formal planning. More equitable, culturally-humble engagement of SMM may facilitate access, uptake, and person-centered planning.
