Ashdown-Franks G, et al. - Via analyzing data from the Global School-based Student Health Survey, researchers examined the link between sedentary behavior (SB) and obesity in 116,762 adolescents (aged 12-15 years) from 41 low- and middle-income countries. The overall prevalence of obesity was 4%, and the prevalence of ≥ 3 hours/day of SB was 26%. Obesity and SB prevalence were lowest in low-income countries and highest in upper-middle-income countries. Overall, increased odds of obesity in adolescence were related to being sedentary for ≥ 3 hours/day.
