Isotemporal Substitution Effect of 24-h Movement Behaviors on Well-Being, Cognition, and BMI Among Older Adults.

ABSTRACT: Background: This study investigated the interdependent relationships among older adults' daily engagement in physical activity (PA), sedentary time (ST), sleep, and their well-being, cognition, and body mass index (BMI). Method: Forty healthy older adults (31 females; Mean [age] = 70.8 ± 5.58) were included in the analysis. Participants wore a Fitbit tracker for an average of 23 h a day, five days a week, over six months. The Fitbit device tracked lightly active time, active time, ST, and sleep durations. Quality of life and cognitive flexibility were assessed using validated instruments. BMI was calculated using participants' self-reported height and weight. A compositional analysis (CODA) investigated the codependent associations among these variables and model time realloc
