BackgroundPsychological disorders and cognitive impairment frequently co-occur in older adults, posing challenges to healthy aging. This study aimed to examine the association between late-life psychological disorders and the risk of developing cognitive impairment.MethodsProspective study analyzed data from 28,706 older adults enrolled in the Taipei City Older Adults Health Examination (2012-2016), among whom 10.3% developed cognitive impairment during follow-up. Psychological disorders were assessed using the five-item Brief Symptom Rating Scale (BSRS-5), and cognitive impairment was evaluated with the Ascertain Dementia eight-item Questionnaire (AD-8). Cox proportional hazards models were applied to estimate the associations.ResultsPsychological disorder severity exhibited a dose-response relationship with cognitive impairment risk. Compared to participants without disorders, those with mild, moderate, and severe symptoms had 2.47-, 3.99-, and 8.60-fold increased risks of cognitive impairment, respectively.ConclusionEarly identification and targeted interventions for psychological disorders may mitigate the risk of cognitive decline and promote healthy aging.

ObjectiveThis study evaluated the effectiveness of a novel multidimensional group intervention aimed at enhancing subjective cognitive and psychosocial functioning in community-dwelling older adults.MethodsSixty cognitively healthy adults aged 65-75 were randomly assigned to an experimental or control group. The 10-week intervention integrated five components: memory compensation, problem solving, emotion regulation, mindfulness, and locus of control. Validated self-report measures were collected at pre-test, post-test, and 12-week follow-up.ResultsMixed repeated measures MANOVA and ANOVA revealed significant improvements in the experimental group across all targeted domains compared to the control group (p < .001). Gains were sustained at follow-up.DiscussionThis structured, skills-based program significantly enhanced perceived cognitive and emotional functioning in healthy older adults. Its emphasis on real-life application and personal agency supports its use in community-based aging interventions. Trial Registration: Neuroage Study (NCT01481246).

BackgroundThe well-known disablement process has been conceptualized as a series of transitions between progressive states of functional decline. We studied joint patterns of change within disablement states defined as walking speed, grip strength, and self-reported disability.Methods1702 participants aged 65 and over were included from the Longitudinal Aging Study Amsterdam, spanning seven waves over 20 years (1996-2016). Group-based multi-trajectory modeling yielded trajectory clusters (TCs) of different patterns of change, further characterized by baseline sociodemographic characteristics, physical and cognitive health, and survival rate.ResultsFive TCs were identified, distinguished by increasing baseline age. Walking speed and disability showed generally concomitant trajectories. Women had poorer trajectories in grip strength than men, but not in walking speed and disability. Poor physical health distinguished especially the poorest, and cognitive impairment distinguished especially the one-before-poorest from the better TCs.DiscussionThe findings suggest that the disablement states are not generally distinct or sequential.

Objectives: To examine the reciprocal associations between walking performance, physical activity (PA), and perceived autonomy in outdoor mobility in 322 older adults. Methods: At baseline and four years later, a 6-min walk test assessed walking performance. A thigh-mounted accelerometer monitored relative PA (acceleration exceeding the individual's preferred walking intensity on the walk test) and absolute MVPA (acceleration exceeding 3 METs) in free-living. Autonomy in outdoor mobility was self-reported using the IPA subscale. Cross-lagged panel model was used for analyses. Results: Higher relative PA at baseline predicted better walking performance four years later and vice versa (p < .05). Baseline MVPA did not predict subsequent walking performance, but better initial walking performance predicted higher subsequent MVPA (p < .001). In both models, only walking performance predicted perceived autonomy at follow-up (p < .05). Discussion: Accumulating enough PA of a sufficient relative intensity can maintain good walking performance, which in turn helps to maintain perceived autonomy in mobility.

Objective: This study tries to investigate the association between two measures of poverty (subjective poverty and material deprivation) with depression and its underlying mechanism(s). Method: A total sample of 28,723 older adults aged 60 years and above was included from the Longitudinal Aging Study in India. Multivariable logistic regression models were used to estimate the association between poverty measures and depression after adjustment of control variables. The Karlson-Holm-Breen (KHB) method was used for mediation analysis to assess the indirect effect of functional, behavioral, and psycho-social factors between poverty measures and depression. Results: The findings suggested that "subjective poverty" has a significantly stronger impact on depression in comparison to material deprivation. Further, functional and psycho-social factors have significantly mediated the relationship between subjective poverty, material deprivation, and depression but are not favorable for behavioral components. Discussion: We believe that policymakers should reconsider the mental health aspects of poverty to promote healthy aging in India.

Objectives: To examine the relationship between children's educational attainment and the risk of food insecurity among older parents and to determine if this relationship varies by the sex and residence of the children. Methods: This study utilized data from the Longitudinal Ageing Survey in India (LASI, 2017-18), comprising 25,914 individuals aged 60+ with at least one living child. Logistic regression, interaction analysis, and propensity score matching were employed to achieve the study's objectives. Results: Having a child with higher education (undergraduate or above) was associated with a 35% reduction in the odds of parents experiencing food insecurity. This negative relationship was significant for both sons' and daughters' education, with daughters' education having higher effect size. Conclusion: In a country like India, characterized by a weak welfare system but a strong collectivist family culture, children's education may play an important role in ensuring older parents' food security.

Objective: The aim of this study was to examine a continuum of grandparenting intensity and its association with physical activity using three perspectives: grandparents are active, the more constraints perspective, and the selection bias perspective. Method: We use 2014 data from the Health and Retirement Study (HRS), a nationally-representative panel study of the US population over the age of 50 and their spouses (n = 17,851). Results: We found that greater grandparenting intensity was inversely associated with physical activity, providing support for both the more constraints perspective and the selection bias perspective. Discussion: We discuss the implications of inequality in which the most advantaged with physical activity are those who were either not grandparents, or grandparents who provided less care.

ObjectivesWe investigated whether functional social support-the degree to which one perceives support is available when needed-is associated with executive function, a key cognitive domain for everyday functioning and adaptation to change.MethodsAnalyses (n = 23,491) utilized cross-sectional data from the Comprehensive cohort of the Canadian Longitudinal Study on Aging (CLSA), a population-based study of community-dwelling adults aged 45-85 years. Executive function was assessed by neurocognitive battery. Perceived social support was measured using the 19-item Medical Outcomes Study-Social Support Survey. Logistic regression models were adjusted for sociodemographic, health, and social covariates.ResultsPositive social interactions as well as affectionate and emotional/informational functional social support were positively associated with executive function.DiscussionSocial support plays an important role in cognitive health. Diversifying social programming beyond tangible social support to target other subtypes of support may help preserve executive function in middle-aged and older adults.

Objectives: To examine the prevalence and predictors of healthy aging among community-dwelling older adults living in Bahir Dar, Ethiopia. Methods: A community-based cross-sectional study included older adults aged 60 and above (n = 845; M_age = 71 years; 56.4% females). Poisson regression estimated the Relative Risk (RR) of factors associated with healthy aging status. Results: 36.7% of respondents were classified as healthy agers. Factors associated with an increased likelihood of healthy aging included reporting not being lonely, adequate nutrition, no multimorbidity, good self-rated health, financial independence, and engaging in at least 1 hour of moderate physical activity per week. Discussion: The proportion of healthy agers in this study was substantially lower compared to developed countries but comparable to the prevalence reported in similar developing nations. Enhancing physical activity, ensuring proper nutrition, interventions to foster social participation engagement, and networking, and managing chronic diseases were identified as promising strategies to promote healthy aging.

Objectives (1) To investigate longitudinal associations between grip strength (GS) and cognition over 4 years in European older adults, (2) to examine differences in temporal associations between men and women and between levels of physical activity, (3) to explore in each year 2015 and 2019 associations between GS quartiles and cognitive performance, and (4) to explore longitudinal associations between GS quartiles (year 2015) and cognitive performance (year 2019). Methods: 25,281 individuals (14,200 women) from 17 European countries aged ≥50 years responded to waves 6th and 8th of the SHARE project. We analyzed GS, a general cognition index, and physical activity level. Results: Panel analyses revealed a bidirectional relationship over 4 years between GS and cognition, with differences between sex, as well as between participants with moderate-to-vigorous and low physical activity levels. Conclusion: Women and participants with low physical activity were more likely to experience cognitive performance deficits 4 years later.
