目的：评估参与“魁北克健康”项目的儿童睡眠时间短与肥胖相关变量之间的关系。设计：横断面研究。研究对象：选取魁北克省三河市小学5 - 10岁的422名儿童（男211名，女211名）参与本研究。测量方法：测量体重、身高、腰围。根据每个年龄段的体重指数（BMI），这些儿童被分为正常、体重不足、超重和肥胖。通过电话向孩子的父母发放了一份详尽的调查问卷。结果：男生超重/肥胖比例为20.0%，女生为24.0%。与报告每天睡眠12-13小时的儿童相比，在调整年龄、性别和其他风险因素后，睡眠时间为10.5-11.5小时的儿童超重/肥胖的调整优势比为1.42(95%置信区间1.09-1.98)，睡眠时间为8-10小时的儿童超重/肥胖的调整优势比为3.45（95%置信区间2.61-4.67）。父母肥胖、父母教育水平低、家庭总收入低、长时间看电视、玩电子游戏或使用电脑、缺乏母乳喂养和缺乏体育锻炼也与儿童超重/肥胖显著相关。此外，我们观察到睡眠时间与男孩体重（-0.33,P < 0.01）、BMI （-0.12, P < 0.01）和腰围（-0.24,P < 0.01）之间存在显著的负相关。结论：睡眠时间与儿童超重/肥胖风险呈负相关。需要进行纵向研究以确认这些变量之间的潜在因果关系。
Objective: To assess the relationship between short sleep duration and obesity-related variables in children involved in the 'Quebec en Forme' Project.Design: Cross-sectional study.Subjects: A total of 422 children (211 boys and 211 girls) aged between 5 and 10 years from primary schools in the City of Trois-Rivieres (Quebec) were selected to participate in this study.Measurements: Body weight, height and waist circumference were measured. The children were classified as normal, underweight, overweight or obese, according to body mass index (BMI) per age. An exhaustive questionnaire was administered by telephone to the parents of children.Results: The percentage of overweight/obesity was 20.0% in boys and 24.0% in girls. When compared to children reporting 12-13 h of sleep per day, the adjusted odds ratio for childhood overweight/obesity was 1.42 (95% confidence interval 1.09-1.98) for those with 10.5-11.5 h of sleep and 3.45 (2.61-4.67) for those with 8-10 h of sleep after adjustment for age, sex, and other risk factors. Parental obesity, low parental educational level, low total family income, long hours of TV watching, playing videogames or computer utilization, absence of breastfeeding and physical inactivity were also significantly associated with childhood overweight/obesity. In addition, we observed a significant negative association adjusted for age between sleep duration and body weight (-0.33, P < 0.01), BMI (-0.12, P < 0.01) and waist circumference (-0.24, P < 0.01) in boys.Conclusion: An inverse association was observed between sleep duration and the risk to develop childhood overweight/obesity. Longitudinal research will be required to confirm a potential link of causality between these variables.
