    Abstract:
    This study aimed to evaluate the relationship between psychosocial variables (peer support, parental support, autonomous motivation, and controlled motivation), availability of physical activity resources in a neighborhood environment, and out-of-school moderate to vigorous physical activity (MVPA) among Chinese adolescents. The questionnaire of Family Life, Activity, Sun, Health, and Eating (FLASHE) Study was used to collect information on demographics, socioeconomic status, psychosocial variables, available physical activity resources in the neighborhood environment, and minutes of out-of-school MVPA. ANOVA analysis and multiple regression analysis were performed. The mean age of the 3833 adolescents included in our analysis was 14.7 years old (SD = 1.7). Peer support (b = 9.35, 95% CI: 7.55-11.15), autonomous motivation (b = 6.46, 95% CI: 4.09-8.82), parental support (b = 3.90, 95% CI: 1.75-6.07), and availability of physical activity resources in neighborhood environment (b = 3.18, 95% CI: 1.99-4.36) were significantly associated with out-of-school MVPA (p < 0.05). Controlled motivation was insignificantly related to minutes of out-of-school MVPA. Boys spent more time on out-of-school MVPA than girls (p < 0.001) and had a high level of peer support, parental support, and motivation (p < 0.05). Our findings suggest that interventions targeting the out-of-school MVPA among Chinese adolescents should focus on the psychosocial variables and neighborhood environment.
