Objectives:In the current study we used an integrated approach to late midlife sexuality. Using a biopsychosocial approach combined with spillover/crossover theory, we examined various common biological (feeling rested and physical intimacy), psychological (positive and negative mood), and social (giving and receiving support) daily processes linked with actor and partner daily physical intimacy.Methods:Data from 191 late midlife, heterosexual, White, couples (97% married, 3% cohabiting) across 14 days were used to examine our hypotheses. Participants had attended some college and about half lived in an urban area.Results:Results from dyadic logistic multilevel models suggest that even when accounting for all covariates, physical activity, positive mood, and both giving and receiving partner support were associated with an increased likelihood of daily physical intimacy. Differences in these associations were found for women compared to men.Discussion:Physical intimacy in late midlife is likely encouraged from a number of factors. Using simplistic designs may inhibit our understanding of important sexual interactions. When compared to health factors, relational factors appear to be more connected to physical intimacy. Physicians, therapists, and community educators can encourage late midlife couples to pay attention to the support they give and receive which may provide an important environment for sexual interactions.
