Results: The PAL was 2.49, SD was 437 minutes per day, MH abnormal rate was 27.9% among Chinese adolescents .The PAL of junior high school students is higher than that of high school students, and the PAL of graduates is lower than that of non-graduates. The MHL of junior high school students gradually decreased with the increase of grade, and the MHL of senior high school students gradually increased with the increase of grade.
Conclusion:The PAL is low, MH problems are serious, and sleep time deprived was severely among Chinese adolescents. The model of PA promote MH for adolescents is established, GSE and SD play an incomplete mediating role in the indirect effect of PA in promoting MH. It was found that SD played a mediating effect in the model of PA promote MH for adolescents etc.
