The research used data from the Health and Retirement Study (2008–2020) for adults 60 years or older, with a sample of 7836 individuals. The data was analyzed using a generalized estimating equation (GEE) model to evaluate the impact of the independent variables on depression. The results showed that factors such as sex, age, and subjective economic level were found to have a significant correlation with depression among the elderly. Additionally, loneliness was found to have a positive correlation with depression, while aging satisfaction and life purpose were found to have an inverse association with depression in older adults. This study suggests that having a positive outlook on life and aging is crucial in preventing depression in older adults. %B International Journal of Mental Health and Addiction %P 1-13 %G eng %R 10.1007/s11469-023-01184-x %0 Web Page %D 2022 %T UMich is the top-funded institution in social science research in the U.S. Take a look at some of these projects. %A Zhu, Jingqi %K Institute for Social Research %K longitudinal study %K minority representation %B Research %I The Michigan Daily %G eng %U https://www.michigandaily.com/research/umich-is-the-top-funded-institution-in-social-science-research-in-the-u-s-take-a-look-at-some-of-these-projects/ %0 Journal Article %J Journal of Statistical Research %D 2020 %T MARGINAL MODELS FOR LONGITUDINAL COUNT DATA WITH DROPOUTS %A Zubair, Seema %A Sinha, Sanjoy K. %K Count data %K Generalized estimating equation %K longitudinal study %K Missing response %K Weighted generalized estimating equation %X In this article, we investigate marginal models for analyzing incomplete longitudinal count data with dropouts. Specifically, we explore commonly used generalized estimating equations and weighted generalized estimating equations for fitting log-linear models to count data in the presence of monotone missing responses. A series of simulations were carried out to examine the finite-sample properties of the estimators in the presence of both correctly specified and misspecified dropout mechanisms.

People age differently, and there is a need to disentangle whether healthy-ageing pathways can be shaped by cohort effects. This study aims to analyse trends in health status in two large nationally representative samples of older adults from England and the USA. METHODS: The sample comprised 55 684 participants from the first seven waves of the English Longitudinal Study of Ageing (ELSA), and the first 11 waves of the Health and Retirement Study (HRS). A common latent health score based on Bayesian multilevel item response theory was used. Two Bayesian mixed-effects multilevel models were used to assess cohort effects on health in ELSA and HRS separately, controlling for the effect of household wealth and educational attainment. RESULTS: Similar ageing trends were found in ELSA (β = -0.311; p < 0.001) and HRS (β = -0.393; p < 0.001). The level of education moderated the life-course effect on health in both ELSA (β = -0.082; p < 0.05) and HRS (β = -0.084; p < 0.05). A birth-year effect was found for those belonging to the highest quintiles of household wealth in both ELSA (β = 0.125; p < 0.001) and HRS (β = 0.170; p < 0.001). CONCLUSIONS: Health inequalities have increased in recent cohorts, with the wealthiest participants presenting a better health status in both the USA and English populations. Actions to promote health in the ageing population should consider the increasing inequality scenario, not only by applying highly effective interventions, but also by making them accessible to all members of society. © The Author(s) 2019; all rights reserved.

However, little is known about the link between smoking and change in personality. Therefore, the present study examined whether current cigarette smoking and smoking cessation are associated with personality change across adulthood. Participants (n = 15,572) aged from 20 to 92 years were drawn from five longitudinal cohorts with follow-ups that ranged from 4 to 20 years. Compared to non-smokers, current smokers were more likely to increase on neuroticism and to decline on extraversion, openness, agreeableness and conscientiousness over time. Compared to the persistent smokers, those who quit had a steeper decline in agreeableness. Cigarette smoking is related to detrimental personality changes across adulthood, and the pattern was not improved by smoking cessation. %B Journal of Research in Personality %V 81 %P 187 - 194 %G eng %U http://www.sciencedirect.com/science/article/pii/S0092656618300825 %9 Journal %R doi.org/10.1016/j.jrp.2019.06.006 %0 Journal Article %J Generations %D 2019 %T Extended work lives and the rediscovery of the 'disadvantaged' older worker %A Lain, D. %A Phillipson, C. %K Aging %K Article %K Education %K England %K human %K human experiment %K longitudinal study %K Pension %K Qualitative Research %K worker %X Disadvantaged older workers are virtually invisible in policy debates about extended working lives. It is important to “rediscover” these workers, who are greater in number than is assumed, according to analyses of the English Longitudinal Study of Ageing and the U.S. Health and Retirement Study. Qualitative research with hospitality workers in England reveals the negative effects of expecting people to work beyond traditional retirement ages when they have low levels of health and education and struggle to continue working in physically demanding jobs. Policy solutions could help reduce this problem.
