Abstract: ObjectivesGreater neighborhood cohesion is associated with better cognitive function in adulthood and may serve as a protective factor against cognitive impairment and decline. We build on prior work by examining the effects of perceived neighborhood cohesion across the life course on level and change in cognitive function in adulthood.MethodsUtilizing longitudinal data from the Health and Retirement Study (1998–2016) and its Life History Mail Survey, we leveraged data from 3,599 study participants (baseline age: 51–89) who participated in up to 10 waves. Respondents provided retrospective ratings of neighborhood cohesion at childhood (age 10), young adulthood (age at the first full-time job), early midlife (age 40), and concurrently at baseline (i.e., late midlife/adulthood); they completed the modified version of the Telephone Interview for Cognitive Status. We fit a univariate latent growth curve model of change in cognitive function across waves and tested whether neighborhood cohesion during each recollected life stage predicted level and change in cognitive function.ResultsGreater neighborhood cohesion during childhood and late midlife/adulthood each predicted higher cognitive function at baseline but not the rate of cognitive decline. The final model showed that greater neighborhood cohesion in childhood and in late midlife/adulthood remained significantly associated with higher baseline cognitive function, even after accounting for one another.DiscussionFindings provide insight into life-course neighborhood contextual influences on cognitive aging. Our results emphasize the need for more research to understand the life-course dynamics between neighborhood environments and cognitive aging.
