目的 了解乌鲁木齐市中学生睡眠状况及其与超重肥胖的相关性,为有效控制中学生超重肥胖提供支持。方法 2016年3-4月在乌鲁木齐市20所中学以班级为单位随机抽取8 242名中学生进行睡眠状况等方面的调查,并分析与超重肥胖之间的关系。结果 乌鲁木齐市中学生睡眠质量得分为(4.97±2.48)分;睡眠质量问题检出率为28.44%,男生(26.36%)低于女生(30.43%),差异有统计学意义(χ2＝16.66,P＜0.01)。中学生平均睡眠时间为(8.18±1.16)h/d,睡眠不足的检出率为48.24%。中学生超重肥胖率为15.47%,其中男生高于女生,城市高于乡村,初中高于高中,差异均有统计学意义(χ2＝191.04、11.21、44.36,P＜0.01)。多元回归分析表明,中学生性别、年龄、睡眠时间与体重指数(BMI)之间存在相关性(P＜0.05),睡眠时间与BMI呈现负相关关系,年龄与BMI呈现正相关关系。Logistic回归分析表明,中学男生睡眠时间不足是导致超重肥胖的危险因素(OR=1.23, 95%CI:1.04~1.47,P=0.02),未发现睡眠质量问题与超重肥胖存在统计学关联,亦未发现女生睡眠时间和质量问题与超重肥胖存在关联。结论 中学生睡眠时间与BMI之间存在密切联系,男生睡眠不足可能是导致超重肥胖的危险因素。
Abstract
Objective To understand the sleep status of middle school students in Urumqi and its correlation with overweight and obesity, in order to provide support for effective control of overweight and obesity in middle school students. Methods A total of 8 242 middle school students from 20 secondary schools in Urumqi were randomly selected to investigate their sleep status from March to April 2016, and their relationship with overweight and obesity was analyzed. Results The sleep quality score of middle school students in Urumqi was 4.97±2.48; The detection rate of sleep quality problems was 28.44%, and it was significantly lower in boys (26.36%) than that in girls (30.43%) (χ2=16.66, P<0.01).The average sleep time of middle school students was (8.18±1.16) h/d, and the detection rate of sleep insufficiency was 48.24%.The overweight/obesity rate of middle school students was 15.47%, and it was significantly higher in boys, urban areas, junior high schools (χ2=191.04,11.21,44.36, P<0.01).Multiple regression analysis showed that gender, age, sleep time were related to body mass index (BMI) in secondary students (P<0.05).Sleep time was negatively correlated with BMI, while age was positively correlated with BMI.Logistic regression analysis showed that sleep time insufficiency in middle school boys was a risk factor for overweight and obesity (OR=1.23, 95%CI:1.04-1.47,P=0.02), boys′ sleep quality was not found correlated with overweight and obesity.Meanwhile, there was no statistical relationship between sleep quality and overweight and obesity in girls. Conclusions There is a close relationship between sleep time and BMI in middle school students.Insufficient sleep of boys may be a risk factor for overweight and obesity.
