Abstract

This study explored the impact of physical activity on the physical health of children and adolescents, to verify the direct relationship between physical activity and physical health, and to explore the mediating role of parental support for physical activity. Method: This study conducted a large-scale survey of 12,857 primary and secondary school students aged 818 in 6 provinces (autonomous regions and municipalities) in China, including Shanghai, Chongqing, Shandong, Fujian, Anhui, and Inner Mongolia. was measured using the "Physical Activity Questionnaire-Children (PAQ-CN)" and was divided into three groups based on classification rules: high physical activity level (PAQ > 3) and moderate physical activity level (2 < PAQ ≤ 3), and low physical activity level (PAQ ≤ 2). The "Adolescent Sedentary Activity Questionnaire-Children" (ASAQ-CN) was used to measure students' overall sedentary activity time in the past 7 days (excluding learning time in cultural classes). Parent Physical Activity Support the Activity Support Scale Multiple Groups (ACTS-CN) was used to measure and calculate the scores of parents' cognitive attitudes and supportive behaviors towards their children's physical activity. The chi-square test was used to observe whether there was a significant association between the indexes and physical health of children and adolescents, and then the degree and direction of the influence of each factor on physical health were analyzed according to the OR the binary logistic regression modeltepwise regressiwas used to test the mediating effect of parental support on the relationship between physical activity and physical health. 1) There is a positive correlation between physical activity level and physical health (Bmedium=0.257Bhigh=0.549). Adolescents with moderate and high levels of physical activity have a 29.4% and 73.1% higher rate of excellent physical health than those with low activity levels (ORmedium=1.294, ORhigh=1.731), respectively. 2) Sitting for more than 4 hours overall lowers the rate of excellence (R4-6h=67.4%, R6-8h=64.7%, R8-10h=55.8%). 3) The mediating effect of maternal support between physical activity and physical health is 0.19, while that of paternal support is 0.138. 1) Improving physical activity levels can effectively promote the physical health of children and adolescents. 2) More than 4 hours poorer the physical health. 3) Parental support is an important mediating factor in promoting adolescents' participation in physical activity and improving physical health.
