abstract="The objectives were to clarify whether the relationship between physical performance and frailty was independently and jointly mediated by movement behaviors and body  composition. We analyzed 871 older adults (476 women) from The Toledo Study for  Healthy Aging. Skeletal muscle index (SMI) and fat index (FI) were determined using  bone densitometry. Sedentary time (ST) and moderate-to-vigorous physical activity  (MVPA) were assessed using accelerometry. The Frailty Trait Scale and The Short  Physical Performance Battery (SPPB) were used to evaluate frailty and physical  performance, respectively. Simple and multiple mediation analyses were carried out  to determine the role of movement behaviors and body composition, adjusted for  potential confounders. ST and MVPA acted independently as mediators in the  relationship between SPPB and frailty (0.06% for ST and 16.89% for MVPA). FI also  acted as an independent mediator in the same relationship (36.47%), while the  mediation role of SMI was not significant. MVPA and FI both acted jointly as  mediators in this previous relationship explaining 58.15% of the model. Our data  support the fact that interventions should simultaneously encourage the promotion of  MVPA and strategies to decrease the FI in order to prevent or treat frailty through  physical performance improvement.<p /> <p>Language: en</p>",
