江西省大学生超重肥胖睡眠时间现状及其相关性

Prevalence and associations of overweight obesity and sleep duration among university students in Jiangxi Province

目的了解江西省大学生超重肥胖、睡眠时间现状及二者相关性,为制定大学生超重肥胖防控措施提供依据。方法2019年9—10月,采用分层随机整群抽样法对江西省11个设区市2605名大学生进行体格检查和问卷调查。结果江西省大学生超重肥胖、肥胖检出率分别为13.0%,3.6%。男生超重肥胖和肥胖检出率(20.8%,6.0%)均高于女生(8.4%,2.1%)(χ^(2)值分别为82.34,25.79,P值均<0.01)。不同经济片区中,超重肥胖、肥胖检出率均以好片区最高(15.8%,5.6%),其次分别为差片区(13.6%,10.3%)和中片区(3.6%,2.0%),差异均有统计学意义(χ^(2)值分别为11.57,14.62,P值均<0.01)。大学生平均睡眠时间为(7.48±1.26)h/d,睡眠充足、不足及过量率分别为69.1%,17.6%,13.3%。男生平均睡眠时间[(7.61±1.46)h/d]高于女生[(7.41±1.11)h/d](t=4.00,P<0.01);睡眠不足率(15.6%)低于女生(18.8%),睡眠过量率(16.1%)高于女生(11.6%),差异有统计学意义(χ^(2)=12.83,P<0.01)。多因素Logistic回归分析结果显示,睡眠不足者超重肥胖、肥胖的风险分别是睡眠充足者的1.41倍和1.69倍(P值均<0.05)。结论江西省大学生超重肥胖问题严重,睡眠不足问题堪忧,且睡眠不足是江西省大学生超重肥胖的相关因素。应保证学生正常睡眠时间,降低超重肥胖的发生风险。

Objective To investigate prevalence of overweight,obesity and sleep duration and its associations among university students in Jiangxi Province,and to provide the basis for developing strategies for prevention and treatment of overweight and obesity among university students.Methods Using the stratified random cluster sampling,2605 university students in 11 districts of Jiangxi Province were investigated with physical examination and questionnaire survey during September to October in 2019.Results The detection rates of overweight-obesity,obesity of university students in Jiangxi Province were 13.0%and 3.6%,respectively.The detection rates of overweight-obesity,obesity of boys(20.8%,6.0%)were higher than girls(8.4%,2.1%)(χ^(2)=82.34,25.79,P<0.01).Significant differences were found in prevalence of overweight-obesity and obesity by economic areas,with highest overweight-obesity in high economic area(15.8%),followed by moderate(13.6%)and poor economicareas(10.3%),and highest obesity in high economic areas(5.6%),followed by poor(3.6%)and moderate economic areas(2.1%)(χ^(2)=11.57,14.62,P<0.01).The average sleep duration was(7.48±1.26)h/d.The rates of adequate sleep,insufficient sleep and excessive sleep were 69.1%,17.6%and 13.3%,respectively.The average sleep time of boys[(7.61±1.46)h/d]was more than that of girls[(7.41±1.11)h/d](t=4.00,P<0.01).The rate of insufficient sleep of boys(15.6%)was lower than that of girls(18.8%),the rate of insufficient sleep of boys(16.1%)was higher than that of girls(11.6%),and the differences were statistically significant(χ^(2)=12.38,P<0.01).The results of multivariate Logistic regression analysis showed that the risk of overweight and obesity,obesity in those with insufficient sleep was 1.41 times and 1.69 times that in those with sufficient sleep,respectively(P<0.05).Conclusion The problem of overweight and obesity of university students in Jiangxi Province is serious,and the problem of insufficient sleep is worrying,and insufficient sleep is a related factor for overweight and obesity among university students in Jiangxi Province.They should develop good sleep habits and ensure normal sleep time to reduce the risk of overweight and obesity.
