The effects of physical exercise, parent-child interaction and peer relationship on adolescent depression: an empirical nalysis based on CEPS data

Currently, depression is the predominant mental illness impacting adolescents, causing severe damage to their overall health. Engaging in physical exercise can not only aid in restoring adolescent physical well-being but also function as a strategy to prevent depression and lower suicide rates. Drawing upon data from the China Education Panel Survey (CEPS) conducted between 2014 and 2015, this study delves into the effects of physical exercise on alleviating depressive symptoms among adolescent students and explores the underlying mechanisms through the lens of parent-child interactions and peer relationships. The mediation effect tests indicate that physical exercise can mitigate adolescent depression by reinforcing parent-child bonds and improving peer connections. Parents and educational institutions should judiciously plan the time for adolescents to engage in both academic pursuits and physical activities, and they should encourage greater participation in sports among adolescents through various means, thereby maximizing the beneficial role of physical exercise in ameliorating adolescent depression.
