Abstract
OBJECTIVE: Weight stigma is associated with impaired health, attributed in part to reductions in health-promoting behaviors. This review analyzed evidence of the association between weight stigma and physical activity (PA) in adults and youth. METHODS: Three databases were searched for terms related to weight stigma and PA. Eligible studies reported the quantitative association between at least one measure of weight stigma and one behavioral measure of PA. RESULTS: A total of 38 studies met eligibility criteria. Of the 29 studies of adults, 3 used objective PA measures, and 79% used an observational, cross-sectional design. Findings of the relationship between weight stigma and PA were mixed. Everyday weight discrimination and internalizing weight stigma were associated with reduced PA in most studies. Several studies found indirect, and not direct, effects of weight stigma on PA when analyses included other individual-level factors. In the nine studies of youth, two used objective PA measures, all were observational, and only one study was longitudinal. Most youth studies found a relationship between weight-based teasing and reduced PA. CONCLUSIONS: Weight teasing, everyday discrimination, and internalization were associated with reduced PA. However, associations were inconsistent and often indirect. Future studies should include objective PA measures with larger samples and longitudinal assessments.
