The early-career speakers utilize data from the Carolina African American Twins Study of Aging (CAATSA), Health and Retirement Study (HRS), and Panel Study of Income Dynamics (PSID) and apply advanced analysis methods. Presentations consider the influence of education, early adult and midlife neighborhood poverty, and pre-retirement work contexts in cognitive aging. Early-life education is well-known as a predictor of dementia. Johnson expands this research by revealing a unique role for education beyond zygosity and socio-environmental factors. Kalousová examines the relevance to late life cognition of early-to-late life residential contexts characterized by neighborhood poverty. Using sequence analysis, she identifies distinct patterns of exposure to neighborhood disadvantage over time. Cumulative exposures to areas with limited resources increased the likelihood of late-life cognitive impairment. Retirement from the workforce often contributes to increased stress, loneliness, and reduced cognitive engagement. Kayser, Xiang, and Smith apply cross-wave dynamic change models to HRS multi-wave data to disentangle bidirectional associations between changes in cognition and loneliness after retirement. They report that over the longer-term both cognitive decline and loneliness increase. Working longer and different retirement trajectories may mitigate cognitive decline. Oh used sequence analysis to identify six work-related trajectories prior to retirement. He finds that working longer and engaging in so-called “encore” careers reduce the probability of later-life dementia. The session concludes with an integrative discussion by Carr of the implications of these studies for future research and policy.","cbCaijBd43DlQWxz","https://ap.wps.com/l/cbCaijBd43DlQWxz","pdf",372948,"English","# Symposium 3175 (Session 3175)\n## Research aims and data sources\n## Education, neighborhood poverty, and work context effects\n## Sequence and dynamic change model findings\n## Retirement, loneliness, and cognitive trajectories\n## Integrative discussion and implications","[{\"question\":\"What research topics does Symposium 3175 cover?\",\"answer\":\"It examines how early-life and midlife contexts, including education, neighborhood poverty, and pre-retirement work conditions, relate to later-life cognition and dementia risk.\"},{\"question\":\"Which datasets are used in the symposium presentations?\",\"answer\":\"Speakers use data from the Carolina African American Twins Study of Aging (CAATSA), the Health and Retirement Study (HRS), and the Panel Study of Income Dynamics (PSID).\"},{\"question\":\"How do the studies link retirement to cognition and loneliness?\",\"answer\":\"Cross-wave dynamic change models suggest that over the longer term, both cognitive decline and loneliness increase after retirement, and working longer or following different retirement trajectories may mitigate cognitive decline.\"}]","COGNITIVE AGING AND DEMENTIA RESEARCH: EXPANDING HORIZONS ON SOCIAL AND ENVIRONMENTAL CONTEXTS - Session 3175 - Symposium | PDF",1790641480]
