Objective:To explore the effects and intrinsic associations of perceived exercise benefits and barriers on physical activity in primary and secondary school students,and to provide a reference basis for enhancing physical activity and reducing sedentary behavior in primary and secondary school students.Methods:In this study,618 students in grades 4～6 of primary school and 1047 students in grades 1～3 of secondary school were randomly selected to investigate the physical activity level,length of sedentary behavior,and perceived levels of exercise barriers and obstacles of primary and secondary school students;the chi-square test was used to compare the differences in the physical activity levels of different genders and school ages,and the t-test was used to compare the differences in the perceptions of the benefits of exercise among primary and secondary school students.Linear regression analysis was performed to reveal the associations.Results:The overall physical activity level of the surveyed students was low,with 66.5%of female students in low-intensity physical activity levels much higher than 46.9%of male students(X2=71.29,P＜0.001);68.6%of secondary school students in low-intensity physical activity level was much higher than 36.1%of primary school students,and 56.0%of primary school students were in moderate-intensity physical activity level much higher than 29.0%of secondary school students(X2=29.0%,P＜0.001);the number of secondary school students in low-intensity physical activity level was much higher than that of primary school students(P＜0.001).29.0%(X2=171.75,P＜0.001).Perceived benefits and barriers to exercise scores were higher for male than female students in primary and secondary schools,and secondary school students scores were higher than primary school students,which were significantly different(P＜0.001).The preventive health and life promotion dimensions of the exercise benefits and barriers perception were significantly associated with the sedentary behavior of male students in primary and secondary schools,and social interaction was significantly associated with the sedentary behavior of female students(P＜0.001);life promotion and social interaction were significantly associated with the level of medium-and high-intensity physical activity of primary and secondary school students,respectively(P＜0.001).Conclusion:The overall physical activity level of the investigated students is seriously insufficient;the cognitive level of the benefits and obstacles of exercise among the investigated primary and secondary school students is higher for boys than for girls;the cognitive level of the benefits of exercise is higher for secondary school students than for primary school students,and the positive cognitive level does not directly promote the improvement of physical activity level;social interaction and time expenditure are the factors influencing the sedentary behaviors of primary and secondary school students,and the preventive health care and life promotion have a greater influence on the sedentary behaviors of boys.Preventive health care and life promotion have a greater impact on the sedentary behavior of male students,while social interaction has a greater impact on the sedentary behavior of female students.
