A lack of diversity in Alzheimer's (AD) and dementia research is an important barrier to identifying strategies for prevention and treatment. Research suggests media coverage of AD/dementia research will familiarize people with the issue and motivate them to place more importance in the issue in general. This study explores how news media may inform groups that are under-represented in AD/dementia through coverage of the issue. A national survey identified the media outlets that were most often consumed and used for health information within target populations. Transcripts from these media outlets were content analyzed to examine AD/dementia coverage. The timeframe included the months before and after the US FDA's approval of the drug Aduhelm and the controversy surrounding it. Results highlight differences in under-represented groups' media consumption patterns and coverage of AD/dementia and indicates a failure to inform about an event that may have widespread effect on Medicare and AD/dementia research.

This study employs a holistic, cluster-based approach to comprehensively examine how daily activity patterns in mid- and later life vary by urban or rural residence and between men and women in China. Employing national time use data, activity patterns and variations by residence and gender were analyzed through sequence analysis, hierarchical clustering, and multinomial logistic regression models. It reveals six activity patterns among urban Chinese individuals, while their rural counterparts exhibit a similar yet distinct set of patterns, highlighting the structural characteristics of time and emphasizing the contrasting differences between rural and urban contexts. Moreover, this study uncovers notable gender disparities, with men more likely to be in paid labor and leisure-oriented clusters, while women tend towards clusters characterized by childcare and household responsibilities. This research provides a time-based perspective that contributes to understanding social stratification in China by examining the structural and heterogeneous nature of daily activities.

Despite the concerted effort to study neighborhoods and their effects, there has been less attention paid to the direct accounts of these processes from residents themselves. This study explores the narratives of older African American women who have aged in place within urban neighborhoods from childhood through later life. Data is utilized from six years of ethnographic observations within two community centers located in Cleveland, Ohio and in-depth, life history interviews with 12 African American women (Mean Age: 72.5). Inductive thematic analysis revealed three themes. These include perceptions related to 1) institutional decline, 2) changes in safety and crime and, 3) changes in neighborhood population. The women's narratives highlight that change is deeply personal. Their perceptions of decline were connected to their biography and how the decline disrupted and re-shaped their daily routines. Studying perceptions of decline is important for better understanding personal experiences of place for under-represented older adults.

This study examines whether age-related cognitive decline varies by race/ethnicity and how edentulism moderates these effects. Data from the Health and Retirement Study (2006-2020), including 23,669 respondents aged 51 and above across 189,352 person-wave observations were analyzed. Of all respondents, 13.4% were edentulous at baseline, with 65.4% identified as non-Hispanic White, 20.5% non-Hispanic Black, and 14.18% Hispanic. Results from linear mixed-effect models indicated that compared to non-Hispanic Whites, Hispanic and non-Hispanic Black participants exhibited lower baseline cognition scores but slower cognitive decline with age. For edentulous Hispanic participants, this slower rate of decline was attenuated by 0.03 units per year (95% CI: -0.06, -0.01, p = .049). The findings highlighted the need for targeted interventions and policies to improve oral health, particularly for Hispanic populations. Addressing oral health disparities could help mitigate cognitive decline in this group and reduce cognitive health disparities across racial/ethnic groups.

The current study examines cohort (i.e., Generation X, Baby Boomers, and Silent Generation) and gender differences in the stability of Mexican-origin family caregivers over time. The data comes from Mexican-origin caregivers to community-dwelling older adults living in the west and southwestern United States from the Caregiving Supplement to the Hispanic Established Populations for the Epidemiologic Study of the Elderly (2010/11-2016). Multinomial logistic regressions with interaction and predicted probabilities demonstrate that female caregivers are more consistent in their caregiving role over male caregivers in every cohort over the two time points (RRR = 0.67; 95% CI = [0.01-0.38]). Among men, predicted probabilities indicate more caregivers from Baby Boomer (.17) and Generation X (0.12) cohorts remain in the caregiver role compared to Silent Generation (.07). The findings suggest that gendered expectations may be changing as male caregivers increase in their provision of family care. Future research should consider generational diversity in Hispanic caregiving experience.

Using data from Wave 5 (2018) of the Mexican Health and Aging Study, this research examines the implications of six social leisure activities for cognition among married and unmarried men and women in Mexico, while considering their physical health and depressive symptoms. The findings reveal some marital status and gender differences and similarities. This study indicates that church attendance and volunteering might be related to poorer cognition, whereas a training course, club participation, board games, and remote communication can provide cognitive benefits. Despite poor vision, poor hearing, and functional limitations, a training course, board games, and remote communication might be associated with better cognition. Yet, in case of poor hearing and depressive symptoms, volunteering, club participation, and board games might be linked to poorer cognition. The insights from this study can help develop intervention programs for improving later-life cognitive functioning through social leisure participation, particularly among individuals with deteriorating health.

Objectives: This study investigates the longitudinal association between spousal caregiving types and cognitive trajectories among middle-aged and older Chinese adults, with a focus on gender differences. Method: Data from the China Health and Retirement Longitudinal Study (CHARLS) (2011-2018) were analyzed, covering 4568 couples aged 45 and above. Caregiving types were Activities of Daily Living (ADLs) caregiving, Instrumental Activities of Daily Living (IADLs) caregiving, and both ADLs/IADLs caregiving. Cognitive function was assessed using tests of memory, orientation, numeric ability, and visuospatial ability. Latent growth curve modeling was used to examine associations between caregiving types and cognitive trajectories. Results: Spouses who only provided IADLs caregiving had slower cognitive decline compared to those who did not provide caregiving, regardless of gender. However, those who provided ADLs caregiving had faster cognitive decline compared to non-caregivers, especially in women. Discussion: These findings highlight the importance of caregiving types as well as the gendered effects of caregiving on cognitive trajectories.

The death of a family member is one of the life's most emotionally distressing experiences, yet its impact on self-perceptions of aging remains understudied. This study examines the relationship between the death of a family member and self-perceptions of aging among middle-aged and older adults using data from the 2014-2016 Health and Retirement Study (n = 11,416). Four types of family death (father death, mother death, spousal death, and child death) were analyzed. Linear regression models with Generalized Estimating Equations were estimated to examine the association between the death of a family member and self-perceptions of aging, as well as the moderation effect of gender. Results indicated that the death of a mother or a spouse is associated with less positive self-perceptions of aging compared to those not bereaved. No significant gender differences were observed in the association between the death of a family member and self-perceptions of aging. Interventions and support are necessary to help the bereaved navigate the bereavement process and maintain a positive outlook on aging in the face of loss.
