ABSTRACT=To investigate and analyse the situation and relationship between adolescent physical activity and self-assessment of health to provide a reference for adolescent physical activity research. Methods: A questionnaire was used to investigate the physical activity and self-rated health of 1804 adolescents aged 14 ~ 18 years. Results: There was a significant relationship between adolescents' physical activity and self-rated health. The coefficient was 0.109 (P < 0.01) in urban areas and 0.127 (P < 0.01) in rural areas. At the same time, it was found that when family income was used as the intermediary variable between physical activity and self-rated health, the intermediary effect was 0.12 (P < 0.01), and the intermediary effect accounted for 25.97%. Conclusion: Adolescent obesity, physical activity, smoking, well-being and physical activity can affect adolescents' self-rated health status. At the same time, it is also found that adolescents' family income is an intermediary variable between physical activity and self-rated health. Suggestions: (1) increase the methods of sports venues, sports organizations and sports activities, improve the possibility of teenagers participating in physical activities, and improve teenagers' self-rated health; (2) There is a large gap between the physical activity and self-rated health of urban and rural adolescents. Increase the guidance of physical activity of adolescents in rural areas and promote the balance of self-rated health of urban and rural adolescents. (3) Family income is the intermediary variable of teenagers' physical activities and self-rated health. Reducing family expenditure through financial transfer payments or reducing taxes and fees can increase the level of teenagers' physical and mental health.
