Abstract
Depressive symptoms are commonly experienced by older adults experiencing cognitive decline or dementia symptoms. Research is sparse in understanding modifiable drivers of depression among older adults with or without dementia. The current study examines the interplay between insomnia, physical activity, and depressive symptoms among cognitively impaired individuals without dementia. We performed a hierarchical regression analysis to investigate these relationships using the Health and Retirement Study (n=1208). Depressive symptoms and insomnia are based on the self-report, and a negative binomial model to evaluate these relationships with incidence rate ratios (IRRs) and 95% confidence intervals examined this interaction. Holding everything else constant, we found that the level of insomnia is positively associated with the level of depressive symptoms in older adults. The results of the interaction terms suggest that the relationship between insomnia and depressive symptoms varies by physical activity but not gender.
