Analysis on Influencing Factors of Adolescents’ Physical Activity from the Perspective of Social Cognitive Theory

Abstract: Objective: To make a systematic review and meta-analysis of the literature on the influencing factors of adolescent physical activity from the perspective of social cognitive theory (SCT) model. Methods: the databases at home and abroad were searched, and 18 literatures meeting the requirements were included. The effect quantities were combined by Stata 15.0 software and analyzed by subgroup. Results: (1) SCT model could predict physical activity in a moderate degree (R2 = 17%, P < 0.01, z = 7.59). (2) Meta-analysis of the literature including self-efficacy, barrier self-efficacy, social support and social status showed that these factors were significantly correlated with physical activity (N ≥ 75%). (3) Influenced by different regions, gender and statistical methods, there are heterogeneity among the research results. Conclusion: SCT model can predict adolescent physical activity to a moderate extent; self efficacy, barriers self-efficacy, social support and social status are the key indicators to predict physical activity; affected by different regions, gender and cultural environment, the prediction results of SCT model on adolescent physical activity are different
