Effect of physical activity, diet, and self-efficacy on physical function in older adults

Katlynn Mathis, University of Rhode Island

Abstract

Background: Many older adults (OA) demonstrate decreased physical function (PF) which may lead to disability. Increased physical activity (PA), eating a healthful diet, and maintaining higher self-efficacy (SE) each improve PF in older adults, but few studies have examined if the combination of these three variables have an additive effect on PF. Additionally, few longitudinal studies have assessed the change in PF in relation to the changes in PA, diet, and SE. Purpose: The purpose of this study was to determine: (a) the relationship between PF and PA levels, fruit and vegetable intake (F&V), and exercise SE; (b) the percentage of variance in PF that is explained by PA levels, F&V intake, and exercise SE; and (c) if changes in PA levels, F&V intake, and exercise SE are related to changes in PF in community-dwelling OA.
