Description
Introduction
The effects of replacing sedentary time with light or moderate- to vigorous-intensity physical activity on frailty are not well known.
Aim
To examine the mutually independent associations of sedentary time (ST), light-intensity physical activity (LPA), and moderate- to vigorous-intensity physical activity (MVPA) with frailty status in older adults.
Methods
A total of 628 people aged ≥65 years from the Toledo Study of Healthy Aging (TSHA) participated in this cross-sectional study. Frailty was measured using the Frailty Trait Scale. Hip-worn accelerometers were used to capture objective measurements of ST, LPA, and MVPA. Linear regression and isotemporal substitution analyses were used to examine associations of ST, LPA, and MVPA with frailty status. Analyses were also stratified by comorbidity.
Results
In single and partition models, LPA and MVPA were negatively associated with frailty. Time in sedentary …
