目的了解浙江省中学生体力活动及参加体育课情况,为评价中学生体力活动及学校体育课开展情况提供参考依据。方法采用多阶段随机整群抽样的方法,对纳入研究的浙江省30个县(区)318所初、高中学校495个班级19 542名初一至高三的中学生进行自编问卷调查。结果在过去的7 d中,调查对象体力活动天数达标率为12.30%,男生为15.30%,女生为9.33%,差异有统计学意义(χ2=161.67,P<0.01)。城市学生体力活动天数达标率为12.77%,农村为12.02%,差异无统计学意义(χ2=2.38,P>0.05)。调查对象每周体育课课时达标率为66.23%,其中初中、普通高中和非普通高中达标率分别为50.72%,90.97%和69.21%,差异有统计学意义(χ2=2 555.88,P<0.01)。结论浙江省中学生体力活动天数及体育课课时不足,应引起相关部门重视,并采取相应的措施。
Objective To understand the physical activities of middle school students in Zhejiang Province and to participate in physical education, and to provide a reference for evaluating the physical activity of middle school students and the development of physical education in schools. Methods A total of 318 schools in 30 counties (districts) in Zhejiang Province and 19 542 middle school students in 495 classes from the first to the third high schools in the study were surveyed by using the method of multi-stage random cluster sampling. Results In the past 7 days, the target rate of physical activity reached 12.30%, 15.30% for boys and 9.33% for girls, the difference was statistically significant (χ2 = 161.67, P <0.01). There was no significant difference in the number of days of physical activity among urban students (12.77% in days and 12.02% in rural areas) (χ2 = 2.38, P> 0.05). The compliance rate of subjects in PE class per week was 66.23%, of which the compliance rates were 50.72%, 90.97% and 69.21% respectively in junior high school, senior high school and non-senior high school, with significant difference (χ2 = 2 555.88, P <0.01) . Conclusions The number of days of physical activity and physical education class time for secondary school students in Zhejiang Province are not enough, which should be taken seriously by the relevant departments and relevant measures should be taken.
