Adolescents' Physical Activity and the Association With Perceived Social Support of Parents and Peers in Indonesia.

This study examined the trends of adolescents' physical activity (PA) and its association with parental and peer support, based on the Indonesia Global School-Based Health Survey. Between 2007 and 2015, prevalence of PA in adolescents declined from 24.4% to 16.5%. Prevalence of active transportation (AT) decreased from 47.2% to 32.3%. Prevalence of sedentary leisure behavior (SLB) declined from 33.6% to 27.2%. Girls' SLB was inversely associated with parental supervision SLB in 2007 (odds ratio [OR] = 0.49; 95% CI = 0.30-0.80) and in 2015 (adjusted OR [AOR] = 0.55; 95% CI = 0.43-0.71), and so was boys' SLB in 2015 (OR = 0.75; 95% CI = 0.59-0.95). Boys' AT was inversely associated with peer support in 2015 (OR = 0.73; 95% CI = 0.59-0.91). Parental control was associated with PA in girls (OR = 1.71; 95% CI = 1.23-2.37), in boys (OR = 1.65; 95% CI = 1.07-2.54), and with SLB among girls in 2015 (OR = 1.28; 95% CI = 1.11-1.47). Hence, adolescents' PA was associated with perceived social support.
