肥胖仍然是一个主要的公共卫生问题。在青少年中，关于肥胖与睡眠时间之间关系的研究有限。我们假设青少年平均睡眠时间少于6小时与肥胖有关。数据来自国家青少年健康纵向研究（ADD健康）;对90，000名年龄在12 - 18岁之间的青少年的调查;调查分几波进行。我们研究的样本人群为13，568人。采用加权多元logistic回归确定第II波肥胖与睡眠持续时间之间的关系，调整了每周不吃早餐≥ 2次;种族、性别、父母收入、TV ≥ 2小时/天、抑郁和第I波肥胖。在第一波，平均年龄15.96±0.11岁;平均睡眠时间7.91±0.04。10.6%和11.2%的青少年分别在波I和波II时肥胖。校正分析表明，波I睡眠时间缩短对波II肥胖的预测作用不显著（p<0.218），纵向上，波I抑郁和TV ≥ 2小时/天与波II肥胖的风险较高相关。抑郁青少年肥胖的可能性几乎是正常青少年的2倍（OR=1.84，95%CI =1.25-2.72），每天看电视≥ 2小时的青少年肥胖的可能性增加37%（OR=1.37，95%CI =1.09-1.72），环境因素包括每天看电视≥ 2小时和抑郁与肥胖显著相关，睡眠时间缩短与肥胖无关。未来需要对青少年进行纵向研究，以确定看电视的时间是否会直接影响睡眠模式，并最终影响肥胖。
Obesity continues to be a major public health issue. In adolescents, there are limited studies on the relationship between obesity and sleep duration. We hypothesied that average sleep duration of less than 6 hours in adolescents was associated with obesity. Data was from the National Longitudinal Study of Adolescent Health (ADD Health); survey of 90,000 youths, ages 12 – 18 years; surveyed in several waves. The sample population for our study was 13,568. Weighted multiple logistic regression was used to identify relationship between obesity at Wave II and sleep duration, having adjusted for skipping breakfast ≥ 2/week; race, gender, parental income, TV ≥ 2hrs/day, depression, and obesity at Wave I. At Wave I, mean age 15.96±0.11 yrs; mean sleep hours 7.91±0.04. 10.6% and 11.2% of adolescents were obese at Waves I and II, respectively. Adjusted analyses suggest that effect of shortened sleep duration in Wave I was not significantly predictive of obesity in Wave II (p<0.218).Longitudinally, depression and TV ≥ 2hrs/day at Wave I was associated with higher risk of obesity at Wave II in adjusted analyses. Depressed adolescents were almost twice as likely to be obese (OR=1.84, 95% CI=1.25–2.72); adolescents who watched TV ≥ 2hrs/day were 37% more likely to be obese (OR=1.37, 95% CI=1.09–1.72).Environmental factors including TV ≥ 2hrs/day and depression were significantly associated with obesity; shortened sleep duration was not. Future longitudinal studies in adolescents are needed to determine whether timing of television watching directly influences sleep patterns, and ultimately obesity.
