【摘要】：目的探索上海市中小学生体力活动、静态行为时间与近视患病率的相关性,为学生近视的防控工作提供参考。方法采用多层整群抽样的方法,抽取上海市中心城区和郊区共8个行政区16所中小学,对入选学校的9 583名中小学生开展问卷调查收集体力活动、静态行为时间等变量,并进行视力检查。分别用单因素和多因素方法分析学生身体活动时间与近视患病率的关联。结果上海市中小学生近视患病率为47.2%,平均每天中等到高强度体力活动(moderate and rigorous physical activity,MVPA)时间为0.57 h(0.25~1.14 h),平均每天总静态时间为5.77 h(2.50~8.00 h),其中做作业时间为2.00 h(1.50~3.00 h),看电视时间为0.50 h(0.33~1.00 h),玩电脑/电子游戏时间为0.33 h(0.00~1.00 h)。经多因素Logistic回归分析,在校正了性别、年龄、父母近视的影响后,做作业时间长是学生近视患病率的危险因素,做作业时间每增加1 h,学生患近视的风险增加9.5%(OR=1.095,95%CI=1.043~1.150)。MVPA达1 h则是学生近视患病率的保护因素,每天MVPA达1 h的学生,其患近视的风险小于每天MVPA不足1 h的学生(OR=0.823,95%CI=0.735~0.921)。结论做作业时间长是上海市中小学生近视患病率的危险因素,而MVPA达1 h则是保护因素,应鼓励中小学生多参加户外体力活动预防近视。
[Abstract]:Objective to explore the correlation between physical activity, static behavior time and myopia prevalence among primary and middle school students in Shanghai, and to provide reference for prevention and control of myopia. Methods Sixteen primary and secondary schools in 8 districts in the city center and suburb of Shanghai were sampled by multi-layer cluster sampling. A questionnaire survey was conducted among 9 583 primary and middle school students to collect variables such as physical activity, static behavior time and so on. The visual acuity was examined. Univariate and multivariate methods were used to analyze the correlation between physical activity time and myopia prevalence. Results the prevalence rate of myopia in primary and middle school students in Shanghai was 47.2, and the average daily (moderate and rigorous physical activity time was 0.57 h (0.251.14 h), the average total static time was 5.77 h (2.50 卤8.00 h), and the homework time was 2.00 h (1.50 ~ 3.00 h),). 0. 50 h (0. 33 1. 00 h),) playing computer / video games 0. 33 h (0. 00 / 1. 00 h).) By multivariate logistic regression analysis, after adjusting for the influence of sex, age and parents' myopia, long homework time was the risk factor of students' myopia. The risk of myopia was increased by 9.5% (OR1.095%). The risk of myopia of students with MVPA of 1 hour was lower than that of students with MVPA less than 1 hour per day (OR0.82395CI0.7351.21). The risk of myopia was increased by 9.5% (OR0.82395CI0.7351.150), and the risk of myopia of students with MVPA of 1 hour per day was lower than that of students with MVPA less than 1 hour per day (OR0.82395CI0.7351.150). Conclusion long homework time is a risk factor for myopia prevalence of primary and middle school students in Shanghai, while MVPA for 1 hour is a protective factor. It is necessary to encourage primary and middle school students to participate in outdoor physical activities to prevent myopia.
