Objectives: The present study sought to investigate the influence of advice on decision making in older age, as well as the potential influence of depressive symptoms and age-related differences in the cognitively demanding emotion regulation on advice-taking.

Method: A nonclinical sample (N = 156; 50% female; 47 young: M age = 29.87, standard deviation [SD] = 5.58; 54 middle-aged: M age = 50.91, SD = 7.13; 55 older: M age = 72.51, SD = 5.33) completed a judge-advisor task to measure degree of advice-taking, as well as measures of fluid intelligence, depressive symptoms, confidence, perceived advice accuracy, and emotion regulation.

Results: Age did not influence degree of advice-taking. Greater depressive symptoms were associated with more reliance on advice, but only among individuals who identified as emotion regulators. Interestingly, older age was associated with perceiving advice to be less accurate.

Discussion: The study contributes to the sparse literature on advice-taking in older age. Cognitive and emotional factors influence the degree to which advice is incorporated into decision making in consistent ways across the adult lifespan. A key difference is that older adults take as much advice as younger adults despite perceiving the advice to be less accurate.

Objectives: This study aimed to investigate perceptions of what it means to "age well" and to explore similarities and differences between a Western and non-Western culture (Britain and Java).

Methods: Qualitative interviews explored how Javanese and British older adults defined aging well, establishing the similarities and differences between cultures. Javanese (n = 14) and British (n = 15) adults aged 61-80 (mean age = 68) participated. The data were analyzed using reflexive thematic analysis and organized with NVivo.

Results: Four themes were identified that captured what it means to age well across cultures: (a) good health is a springboard for aging well; (b) holding a positive outlook is a decisive factor in aging well; (c) "having enough" and "feeling safe" provide peace of mind; and (d) spirituality and religiosity provide tranquility. Although both cultures mentioned similar factors, there were variations in the interpretations and emphasis within themes. For example, Javanese participants emphasized the importance of the social environment whereas British participants highlighted the physical environment.

Discussion: Differences between cultures are important for understanding how best to support people as they age. For example, in Java, aging well may be best supported by providing a vibrant social environment. For people in Britain, having a safe and secure physical environment may be more important.

Objectives: Examine racial/ethnic disparities in 30-day readmission and frequent hospitalizations among Medicare beneficiaries with dementia in traditional Medicare (TM) versus Medicare Advantage (MA).

Methods: In this case-control study, we used 2018-2019 TM and MA claims data. Participants included individuals 65+ with 2 years of continuous enrollment, diagnosis of dementia, a minimum of 4 office visits in 2018, and at least 1 hospitalization in 2019, (cases: TM [n = 36,656]; controls: MA [n = 29,366]). We conducted matching based on health-need variables and applied generalized linear models adjusting for demographics, health-related variables, and healthcare encounters.

Results: TM was associated with higher odds of 30-day readmission (OR = 1.07 [CI: 1.02 to 1.12]) and frequent hospitalizations (OR = 1.10 [CI: 1.06 to 1.14]) compared to MA. Hispanic and Black enrollees in TM had higher odds of frequent hospitalizations compared with Hispanic and Black enrollees in MA, respectively (OR = 1.35 [CI: 1.19 to 1.54]) and (OR = 1.26 [CI: 1.13 to 1.40]). MA was associated with lower Hispanic-White and Black-White disparities in frequent hospitalizations by 5.8 (CI: -0.09 to -0.03) and 4.4 percentage points (PP; CI: -0.07 to -0.02), respectively. For 30-day readmission, there was no significant difference between Black enrollees in TM and MA (OR = 1.04 [CI: 0.92 to 1.18]), but Hispanic enrollees in TM had higher odds of readmission than Hispanics in MA (OR = 1.23 [CI: 1.06 to 1.43]). MA was associated with a lower Hispanic-White disparity in readmission by 1.9 PP (CI: -0.004 to -0.01).

Discussion: MA versus TM was associated with lower risks of 30-day readmission and frequent hospitalizations. Moreover, MA substantially reduced Hispanic-White and Black-White disparities in frequent hospitalizations compared with TM.

Background: This study aims to investigate the association and dose-response relationship between depression, dementia, and all-cause mortality based on a national cohort study of older adults in Japan.

Methods: We conducted a longitudinal study of 44,546 participants ≥65 years from 2010-2019 Japanese Gerontological Evaluation Study. The Geriatric Depression Scale-15 was used to assess depressive symptoms and the long-term care insurance was used to assess dementia. Fine-Gray models and Cox proportional hazard models were used to explore the effect of depression severity on the incidence of dementia and all-cause mortality, respectively. Causal mediation analysis were used to explore the extent of association between dementia-mediated depression and all-cause mortality.

Results: We found that both minor and major depressive symptoms were associated with the increased cumulative incidence of dementia and all-cause mortality, especially major depressive symptoms (p < .001). The multivariable-adjusted hazard ratios (HRs) and 95% confidence intervals (CIs) for dementia were 1.25 (1.19-1.32) for minor depressive symptoms and 1.42 (1.30-1.54) for major depressive symptoms in comparison to non-depression; p for trend < .001. The multivariable-adjusted HRs and 95% CIs for all-cause mortality were 1.27 (1.21-1.33) for minor depressive symptoms and 1.51 (1.41-1.62) for major depressive symptoms in comparison to non-depression; p for trend < .001. Depression has a stronger impact on dementia and all-cause mortality among the younger group. In addition, dementia significantly mediated the association between depression and all-cause mortality.

Discussion: Interventions targeting major depression may be an effective strategy for preventing dementia and premature death.

Objective: The 1940 Census is a valuable resource for understanding various aspects of historical populations in the United States. Recently, the National Social Life, Health and Aging Project (NSHAP) integrated 1940 Census data into its extensive dataset, providing researchers with an opportunity to explore new avenues of life course investigation. We leverage the newly-introduced measures of childhood residential environment and evaluate their potential predictive utility in older adult cognitive functioning net of childhood and adulthood characteristics known to be key risk factors for poor cognition.

Method: We analyzed 777 respondents who were children in 1940 (age<17) that have been linked to the 1940 U.S. Census. We used childhood geographic location, homeownership status, household composition, and parental nativity as predictors. Cognitive function was measured using the Montreal Cognitive Assessment.

Results: Regression analysis showed that growing up in an urban area was associated with better cognitive function, while being born in the South was linked to poorer cognitive function, even after controlling for childhood health, parental education, educational attainment, stroke, and smoking status. Additionally, childhood multigenerational household was associated with better cognitive function, and childhood family size was associated with poorer cognitive function. However, these associations became statistically insignificant with the inclusion of educational attainment. We did not find homeownership and parental nativity to be associated with cognitive function.

Discussion: The findings may shed light on the potential long-term effects of childhood circumstances on cognitive aging processes. Implications for current literature and directions for future research are discussed.

Objectives: Personality traits are broadly related to medical conditions, but there is limited research on the association with the risk of arthritis. This multicohort study examines the concurrent and prospective associations between personality traits and arthritis risk.

Methods: Participants (N > 45,000) were mostly middle-aged and older adults from 6 established longitudinal cohorts. Baseline assessments of personality traits, covariates (age, sex, education, race, ethnicity, depressive symptoms, body mass index, and smoking), and arthritis diagnosis were obtained in each sample. Arthritis incidence was assessed over 8-20 years of follow-up.

Results: The meta-analyses identified an association between higher neuroticism and an increased risk of concurrent (odds ratio = 1.20, 95% confidence interval [CI] = 1.16-1.24; p < .001, I2 = 40.27) and incident (hazard ratio = 1.11, 95% CI = 1.08-1.14; p < .001, I2 = 0) arthritis and between higher conscientiousness and a decreased risk of concurrent (odds ratio = 0.88, 95% CI = 0.86-0.90; p < .001, I2 = 0) and incident (hazard ratio = 0.95, 95% CI = 0.92-0.98; p = .002, I2 = 41.27) arthritis. Higher extraversion was linked to lower risk of concurrent (odds ratio = 0.92, 95% CI = 0.88-0.96; p < .001, I2 = 76.09) and incident (hazard ratio = 0.97, 95% CI = 0.95-0.99; p = .018, I2 = 0) arthritis, and openness was related to lower risk of concurrent arthritis (odds ratio = 0.96, 95% CI = 0.93-0.99; p = .006, I2 = 35.86). Agreeableness was unrelated to arthritis. These associations were partially accounted for by depressive symptoms, body mass index, and smoking. There was no consistent evidence of moderation by age or sex.

Discussion: Findings from 6 samples point to low neuroticism and higher conscientiousness as factors that reduce the risk of arthritis.

Objectives: Companions (i.e., friends who spend time together) are important for the well-being of older adults. Senior centers in the United States are places for older adults to participate in group activities and form and maintain companionships. However, differences in mobility and transportation may affect the ability of older adults to leverage senior center activities into actual companionships.

Methods: This social network analysis was conducted to characterize the companionship network among members of a senior center in relation to their life-space mobility and transportation resources. An exponential random graph model was estimated to identify mobility- and transportation-related correlates of the likelihood of a companionship tie among senior center members (N = 42).

Results: Members had an average of 2 companionships with one another (M = 2.2, SD = 2.7). Companionships were more likely for members with greater life-space mobility (p = .009), who attended the senior center more frequently (p = .004), with automobile ownership in their households (p = .034), and who were not transportation cost-burdened (i.e., spent less than 15% of their income on transportation, p = .005). Demographic characteristics, limitations on instrumental activities of daily living, and being at risk for depression were not significantly associated with the likelihood of companionships.

Discussion: These findings extend previous knowledge of the role of life-space mobility and transportation in supporting general social participation for older adults to include the importance of transportation and mobility for having companions within a senior center.

Objectives: Although higher activity diversity is associated with higher well-being at the between-person level, it is unknown whether a day with higher activity diversity is related to higher well-being within persons. Within 24 hr per day, there are a limited number of activities on which individuals could spend their time and energy. Personal resources could influence the expenditure of energy and thus the experience with daily activities. This study examined daily associations between activity diversity and well-being and whether age and self-related health moderated the associations.

Methods: For seven times per day over 2 weeks, 129 retired older adults (Mage = 73.9 years, SDage = 5.6) reported their present activity engagement and positive and negative affect. Daily activity diversity was operationalized as the number of different activity types reported per day. Daily positive and negative affect were assessed as the average of a range of high- and low-arousal affective states. Self-rated health was assessed with an item from the 12-Item Short-Form Health Survey at baseline.

Results: Multilevel models showed that daily activity diversity was unrelated, on average, to daily positive or negative affect at the between- and within-person levels. Daily activity diversity was associated with lower daily positive affect in participants with lower self-rated health, but the Johnson-Neyman regions of significance were outside of the range of observed data.

Discussion: Divergent patterns were observed in the within-person associations between activity diversity and well-being across participants. Results are discussed in the context of time use and well-being in older age.

Objectives: This study aimed to investigate the cognitive functioning of formerly incarcerated older adults compared to their never-incarcerated counterparts, focusing on immediate and delayed verbal recall.

Methods: Data are from 2,003 respondents who participated in the National Longitudinal Study of Adolescent to Adult Health-Parent Study (AHPS; ages 47-82, mean age 62). AHPS participants were administered word recall memory exercises to the parent respondent from the Rey Auditory-Verbal administered Learning Test, including (a) 90-s (immediate or short-term verbal memory), (b) 60-s recall tests (delayed or long-term verbal memory), and (c) combined word recall on the 90-s and 60-s tests.

Results: Adjusting for control variables, respondents who reported prior incarceration had a lower rate of verbal recall on the combined word recall (incidence risk ratio [IRR] = 0.915, 95% confidence interval [CI] = 0.840, 0.997) and immediate word recall (IRR = 0.902, 95% CI = 0.817, 0.996). When restricting the sample to respondents over age 60, prior incarceration was associated with lower combined word recall (IRR = 0.847, 95% CI = 0.752, 0.954), immediate word recall (IRR = 0.857, 95% CI = 0.762, 0.963), and delayed word recall (IRR = 0.834, 95% CI = 0.713, 0.974).

Discussion: This study underscores the adverse impact of prior incarceration on cognitive functioning in the older adult population, emphasizing the need for targeted interventions and support for formerly incarcerated older adults. The results reinforce the importance of addressing the long-term consequences of incarceration, especially as individuals enter older adulthood.

Objectives: Role theory suggests occupying simultaneous family caregiving and employment roles in midlife may exert positive and negative effects on psychological health. However, there is a lack of causal evidence examining the degree to which combinations of these roles influence psychological health at the intersection of gender and racial identity.

Methods: Longitudinal data from the Health and Retirement Study (2004-2018) are used to estimate a series of individual fixed effects models examining combinations of employment status and parental caregiving situation on Center for Epidemiological Studies-Depression Scale (CES-D) depression scores among Black and White men and women aged 50-65. Subsequent models were stratified by intensity of caregiving situation and work schedule.

Results: Individual fixed effects models demonstrate combining work, and parental caregiving is associated with greater depressive symptoms than only working, and with lower depressive symptoms than only caregiving, suggesting that paid employment exerts a protective effect on psychological health whereas parental caregiving may be a risk factor for depressive symptoms in later life. Analyses using an intersectional lens found that combining paid work with parental caregiving exerted a protective effect on CES-D scores among White women and men regardless of participants' intensity of care situation or work schedule. This effect was not present for Black men and women.

Discussion: Accounting for intersectionality is imperative to research on family caregiving, work, and psychological health.
