摘要
目的探讨广东省青少年睡眠时间、运动情况与超重肥胖的关系,为青少年体重管理提供参考。方法采用随机整群抽样方法,抽取广东省深圳市、阳江市、清远市3 020名初中和高中学生为研究对象,采用青少年身心健康问卷调查睡眠时间、运动等情况,测量研究对象的身高、体重,并计算体质量指数(BMI)。结果广东省青少年学生超重肥胖的发生率为11.49%,初中生超重肥胖发生率为13.18%,高中生为9.54%;初中生和高中生每天睡眠时间<8 h的比例分别为74.83%和94.23%;初中生参加充足(≥3次/周)大强度和小强度运动的比例分别为32.61%和29.02%,高中生分别为18.52%和18.87%,差异有统计学意义(χ2值分别为77.523,42.063,P值均<0.05)。单因素分析显示,高中生每天睡眠时间<8 h的学生超重肥胖发生率为9.99%,高于睡眠充足的学生(2.47%)。多因素分析显示,在调整性别、运动、城乡、父母文化程度、是否独生等因素以后,睡眠时间<8 h/d仍是高中生超重肥胖的独立危险因素(OR=2.77,95%CI=1.34~5.75),运动情况与青少年超重肥胖无相关性。结论睡眠不足为高中生超重肥胖发生的独立危险因素,是否参与运动与青少年超重/肥胖的发生无相关。
Objective To assess the prevalence of overweight/obesity, and its association with sleep duration and physical activities, so as to provide evidences for weight management. Methods Cluster sampling method was employed to select 3 020 students from middle and high schools from Shenzhen, Yangjiang, Qingyuan in Guangdong Province to participate a school-based cross-sectional study with self-reported questionnaires on sleep duration, exercise. And they were investigated about weight and height to analyze their BMI. Results The prevalence of overweight/obesity was 11.49% （ 13.18% in junior school students, 9.54% in senior school students）, about 94.23% of the senior school students obtain less than 8 hours of sleep per day, while 74.83% of the junior school student gets less than 8 hours of daily sleep; The rate of participation of adequate high intensity exercise and small intensity exercise were 32.61% and 29.02% among junior school students, while 18.52% and 18.87% among senior school students. The differences were of statistical significance（ P〈0.05）. Univariate analysis showed that the prevalence rate of obesity/o- besity was higher among those who sleep less than 8 hour a day than those who sleep enough among senior high school students. Multivariate analysis showed that after adjusting for socio-demographic variables, physical activity and gender, the odds ratio （OR） for overweight/obesity comparing sleeping 〈8 hours with ≥ 8 hours was 2.77 （95%CI= 1.34-5.75） among senior school student. There was no significant association between physical activity and overweight/obesity in adolescents. Conclusion Short of sleep is the single risk factor of overweight and obesity among senior school students, while physical activity may not associated with overweight and obesity among junior and senior school students.
