Associations between sleep and the body mass index (BMI) and overweight status of children and adolescents were estimated using longitudinal data from a nationally representative sample of 2,281 children aged 3-12 years at baseline. Controlling for baseline BMI, children who slept less, went to bed later, or got up earlier at the time of the first assessment had higher BMIs 5 years later and were more likely to be overweight. Child age moderated the relationship between bedtime and BMI. In addition, the study reports nationally representative data on the sleep habits of American children aged 3-18 years. This study underscores the likely importance of sleep on children's physical health and suggests that sleep is important for understanding childhood weight problems.
利用来自全国代表性样本的纵向数据，对2281名3至12岁儿童在基线时的睡眠与体重指数（BMI）及超重状况之间的关联进行了评估。在控制基线BMI的情况下，首次评估时睡眠时间较少、上床睡觉较晚或起床较早的儿童，5年后BMI较高，且更有可能超重。儿童年龄对就寝时间与BMI之间的关系有调节作用。此外，该研究报告了美国3至18岁儿童睡眠习惯的全国代表性数据。这项研究强调了睡眠对儿童身体健康可能具有的重要性，并表明睡眠对于理解儿童期体重问题很重要。
