Abstract
24 h movement behaviors, specifically physical activity (PA), sedentary behavior, and
sleep, play a crucial role in the prevention and intervention of childhood obesity. This study aimed
to examine the association of 24 h movement behaviors with weight status and body composition
among Chinese primary school children. Using a random stratified sampling, 978 eligible participants
(9.1 ± 1.4 years, 53.2% boys) were recruited from 1 May to 15 July 2021. Demographics included
children’s age, gender, grade, parents’ education level, and household income. Movement behaviors
were measured by validated self-reported scales. Weight status and body composition (percent of
body fat, PBF; fat-free mass, FFM; skeletal muscle mass, SMM) were measured objectively. Results
indicated that participants who were younger, boys, and at lower grade showed higher guidelines
adherence. PA was inversely associated with PBF, while screen time (ST) was positively associated
with overweight/obesity risk and FFM. Sleep showed no association with any health indicators.
Meeting the behavioral guidelines was associated with better weight status and lower PBF, yet not
with FFM and SMM. Interventions to improve the Children’s weight status and PBF should involve
enhancing their overall movement behaviors and considering their demographic differences. More
research on examining the association of movement guidelines adherence with body composition
indicators is needed.
