Abstract

Objectives. This study examined spousal concordance of physical activity trajectories among middle-aged and older married couples and the influences of recent diseases and functional difficulties on individuals' trajectories and those of their spouses'.Method. Participants included 5,074 married couples aged 50 or older in the Health and Retirement Study in 2004-2010. Participants were categorized into 4 physical activity trajectories (i.e., stable active, adopters, relapsers, and stable sedentary) using confirmatory latent class growth analysis. Individuals' trajectory memberships were predicted by their spouses' memberships, together with recent diseases and functional difficulties of both couple members.Results. In the main, corresponding husbands' trajectories predicted wives' trajectories and vice versa. More functional difficulties predicted higher likelihoods of unfavorable trajectories among individuals but not of their spouses'. Among wives, more recent diseases predicted slightly more physical activity in subsequent data waves but not trajectory memberships.Discussion. Results supported spousal concordance in physical activity trajectories. The negative impact of functional difficulties was considerably contained within individuals. Increases in physical activity after acquiring diseases among wives were small and short lived. More research is needed to understand the underlying processes, which can be used to improve the design of future physical activity interventions directed toward women, men, and couples. © 2013 © The Author 2013.
