This cross-sectional study examined whether and to what extent physical activity (PA) mediated the effect of chronic pain on physical frailty in a sample of predominantly older Latinx adults. Study participants were 118 community-dwelling older adults in southwest United States. Physical frailty was measured by a summary score of physical function tests. Pain severity and pain interference were measured by the Brief Pain Inventory. PA levels were defined as meeting the PA recommendation by 7-day accelerometry. Pain outcomes and PA were associated with physical frailty, respectively. Hierarchical regression analysis revealed that PA mediated the relationship between pain severity and physical frailty. However, no mediation effect of PA was found in the relationship between pain interference and physical frailty scores. Higher levels of PA buffered the negative effect of pain severity on physical frailty. Future studies should pay attention to PA promotion to prevent the negative consequences of frailty in older minority adults.
