目的了解新疆和田地区维吾尔族中小学生超重、肥胖现状及其与睡眠时间的关系,为促进维吾尔族中小学生健康成长提供支持。方法采用随机整群抽样的方法,在新疆和田地区抽取30所中小学校180个班级的7 118名维吾尔族学生,进行身高、体重、睡眠时间的测试,并对结果进行统计分析。结果新疆和田地区维吾尔族在校中小学生的超重率为11.14%,肥胖率为5.61%。维吾尔族男生超重、肥胖检出率为15.46%,7.11%,女生为6.24%,3.90%,差异均有统计学意义(χ~2值分别为152.23,34.51,P值均<0.01)。维吾尔族中小学生不同年龄段超重和肥胖率相比较差异均有统计学意义(χ~2值分别为56.03,114.25,P值均<0.01)。维吾尔族中小学生每天锻炼时间≥1 h的学生占14.99%;每天看电视≥2 h的占11.90%;睡眠不足学生报告率为92.40%。睡眠不足学生超重检出率为11.46%,睡眠充足学生超重检出率为7.21%,差异有统计学意义(χ~2=9.14,P<0.01)。Logistic回归分析显示,睡眠不足维吾尔族中小学生的超重风险是睡眠充足者的1.96倍。结论睡眠不足是维吾尔族中小学生超重的危险因素。应通过改善睡眠状况干预维吾尔族中小学生的体重。
Objective To understand the prevalence of overweight and obesity among Uighur primary and secondary school students in Hetian area and their relationship with sleep time and to provide support for the healthy growth of Uighur primary and secondary school students. Methods A total of 7 118 Uyghur students of 180 classes from 30 primary and secondary schools in Hetian were enrolled in this study. The results of height, weight and sleep time were tested and the results were statistically analyzed. Results The overweight rate of primary and secondary school students in Uygur in Hetian was 11.14% and the obesity rate was 5.61%. The prevalence of overweight and obesity among Uyghur boys was 15.46% and 7.11% respectively, while girls were 6.24% and 3.90%, respectively (all χ ~ 2 values were 152.23 and 34.51, P <0.01 respectively). There were significant differences in the overweight and obesity rates among Uyghur primary and secondary school students at different ages (χ ~ 2 values were 56.03 and 114.25, P <0.01 respectively). Uyghur primary and secondary school students exercise more than 1 h per day accounted for 14.99% of students; every day watching TV ≥ 2 h accounted for 11.90%; lack of sleep students reported rate of 92.40%. The detection rate of overweight was 11.46% for those who did not get enough sleep, and 7.21% for those who had adequate sleep. The difference was statistically significant (χ ~ 2 = 9.14, P <0.01). Logistic regression analysis showed that the risk of overweight among primary and secondary school students who lack sleep was 1.96 times that of those with adequate sleep. Conclusion Insufficient sleep is a risk factor for overweight school students in Uighur. Intervention should be made by Uighur schoolchildren by improving their sleep quality.
