Abstract
Depression in adolescents is a major public health disorder. The relationship between physical activity and risk of depression in adolescents was examined using three waves of data from the China Family Panel Studies in 2020. The risk of depression was significantly higher among adolescents who reported lower frequency and shorter duration of physical exercise than those who reported physical exercise more frequently and for a longer duration. The risk of depression was significantly higher among adolescents who reported intense physical exercise than those who reported little or no intense physical exercise. The amount of time spent on housework by adolescents is inversely associated with depression. These results provide somewhat stronger evidence for an activity–depression link than previous studies and suggest a differential role for different types of physical activity, such as exercise and housework. The overall model predicting depression in adolescents (LR chi-squared = 95.974, p < 0.001, Nagelkerke R-square = 0.183) was statistically significant. To effectively control depression in adolescents, the government, schools and parents need to act together to guide adolescents towards participation in appropriate physical activities. The appropriate level of physical activity is for adolescents to experience breathing, rapid heartbeat, and slight perspiration.
Highlights
The depression rate among adolescents has been on the rise, and “silent killers” are targeting adolescents [2]
Gender, education level, type of residence, and city type were probably not associated with adolescent depression
The results of this study show that physical exercise has a positive effect on reducing depression in adolescents, which is different from previous studies showing that the effects of exercise on depression relief are “moderate at best” or statistically insignificant [12–14]
Summary
Depression is a mood disorder with the highest incidence of psychological problems in adolescents, with significant and persistent depression as the main clinical feature [1]. Adolescents, as a high-level reserve talent echelon in society, have received active attention from society for their mental health issues. The depression rate among adolescents has been on the rise, and “silent killers” are targeting adolescents [2]. The prevention and treatment of depression in adolescents is a matter of urgency. Adolescence is a critical stage for developing healthy habits [3]. In 2021, the Chinese Ministry of Education began to include depression screening in the context of students’ health checkups. More work is needed to truly keep “silent killers” away from adolescents
