摘要/Abstract

摘要： 【目的】研究上海青春前期儿童睡眠时间与体脂指标的相关性,为改善儿童睡眠质量与肥胖的发展提供依据。【方法】采用分层整群随机抽样方法,抽取上海市10所小学的五年级学生1 588名进行社会经济状况、睡眠问卷调查以及体格测量,测量指标包括身高、体重、腰围、臀围以及皮下脂肪等,并进一步计算体质指数(body mass index,BMI)及BMI和腰围的Z值,腰围/身高比和体脂百分比。被选儿童中,男童的比例为52.08%(827名),年龄(10.82±0.39)(9.42~14.08)岁。【结果】肥胖的发生率为11.9% (男生15.0%,女生 8.5%,P<0.001)。在校正了肥胖的高危因素后,与睡眠时间≥10 h的儿童相比,睡眠时间不足9 h的儿童有显著较高的BMI、BMI Z值,腰围,腰围Z值,腰围/身高比及体脂百分比(P<0.05)。【结论】青春前期儿童睡眠时间不足与体脂指标显著相关。采取措施改善儿童的睡眠状况可能有助于遏止肥胖迅速发展。

Abstract: 【Objective】 To investigate the association between sleep duration and adiposity among Chinese preadolescents. 【Methods】 Totally 1 588 fifth-grade students were sampled by stratified cluster random sampling from 10 primary schools of Shanghai.Socioeconomic status and sleep duration were from parental or self reported questionnaires.Height,weight,body mass index (BMI),waist circumference,Z scores of BMI and waist circumference,waist -height ratio and body fat percentage were assessed.Among children participated,boys accounted for 52.08 %( 827).The mean age o f the sample was 10.82±0.39 years old (9.42~14.08). 【Results】 The prevalence of obesity overall was 11.9% (boys 15.0%,girls 8.5%,P<0.001).Compared with those who slept ≥10 h,those who slept < 9 hours had a significantly higher BMI,BMI Z score,waist,waist Z score,waist/height ratio and body fat percentage after adjusting for potential confounders. 【Conclusion】 Short sleep duration was significantly associated with higher adiposity indices in Chinese adolescents,suggesting this may be a modifiable risk factor for adiposity.
