Composition of time in movement behaviors and weight change in Latinx, Black and white participants.

ABSTRACT:

Background

The relationship between time-use behaviors and prospective weight change is poorly understood.

Methods

A subset of Cancer Prevention Study-3 participants (n = 549, 58% women, 66% non-Latinx white) self-reported weight in 2015 and 2018 and completed an accelerometer protocol for seven days. Sedentary time, sleep, light, moderate, and vigorous intensity physical activity (PA) were treated as a compositional variable and multiple linear regression was used to examine associations between activity composition and weight change stratified by sex and race/ethnicity. Compositional isotemporal substitution analysis was used to quantify change in weight associated with reallocating 30 min./day.

Results

Activity composition was associated with weight change among wo
