Objective: To study the status of physical activities and its influencing factors among parents of primary and secondary school students, to provide basis for improving students' parents physical activities.
Methods: A total of 12 501 parents ofprimary and secondary school students from Shenyang, Guangzhou, Chengdu and Wuhan were selected by stratified random cluster sampling. They completed a self-designed questionnaire that was derived from International Physical Activity Questionnaire( IPAQ). Logistic regression model was used to analyze the influence of region, stage of school, gender, age, education level, occupation and economic level on physical activities among parents of primary and secondary school students.
Results: The rate of students' parents with insufficient physical activity was 58. 3%, and the rate of students' parents spending2 h and more on sedentary activities per day was 55. 7%. Logistic regression analysis showed that compared with primary school students ' parents, the risk of insufficient physical activity and spending 2 h and more on sedentary activities of junior and senior middle school students' parents were decreased( the risk of insufficient physical activity:ORjunior( 95% CI) = 0. 796( 0. 728-0. 869), ORsenior( 95% CI) = 0. 746( 0. 683-0. 815); the risk of spending 2 h and more on sedentary activities: ORjunior( 95% CI) =0. 823( 0. 750-0. 904), ORsenior( 95% CI) = 0. 788( 0. 712-0. 872)). Compared with students' parents with primary school education, the risk of insufficient physical activity and spending 2 h and more on sedentary activities of parents with junior college or above education were increased( the risk of insufficient physical activity: OR( 95% CI) = 1. 288( 1. 107-1. 497); the risk of spending 2 h and more on sedentary activities: OR( 95%CI) = 1. 303( 1. 120-1. 515)). Compared with housework/unemployed/retirees, the risk of insufficient physical activity and spending 2 h and more on sedentary activities of agricultural/equipment operators were decreased( the risk of insufficient physical activity:OR( 95% CI) = 0. 755( 0. 634-0. 899); the risk of spending 2 h and more on sedentary activities: OR( 95% CI) = 0. 731( 0. 617-0. 867)).
Conclusion: The rate of insufficient physical activity and spending 2 h and more on sedentary activities among students' parents were relatively higher. The influencing factors on physical activity level and sedentary activity time were region, stage of school, education level and occupation. Specific interventions should be developed for different people.
