肥胖在美国和其他发达国家已经达到了流行病的程度，尤其是在青少年中。如果能够确定除饮食和体育活动等传统因素外导致肥胖的其他因素并采取行动，就可以对公众健康产生重大影响。本研究调查了低睡眠质量和肥胖之间是否存在联系，研究对象是三种族、横断面样本（n = 383），包括11-16岁的男性和女性青少年。睡眠质量表示为两个变量，即总睡眠时间和通过24小时腕动仪获得的睡眠干扰时间。身体脂肪百分比和身体质量指数（BMI）一起被用来定义肥胖。在描述睡眠与肥胖发生关系的模型中，考虑了人口统计学和行为混杂因素的潜在影响。肥胖青少年睡眠少于非肥胖青少年（P < 0.01）。每少睡一个小时，肥胖的几率就增加80%。睡眠障碍与肥胖无直接关系，但影响身体活动水平（P < 0.01）。睡眠障碍每增加一小时，白天的体力活动就会减少3%。上述观察结果独立于潜在的混杂变量。青少年睡眠不足和睡眠质量差可能是预防儿童肥胖的重要因素。点。j .的嗡嗡声。生物学报，2002,14:762-768。(C) 2002 Wiley-Liss, Inc。
Obesity has reached epidemic proportions in the U.S. and more developed countries, particularly so among adolescents. A substantial impact on public health could be achieved if other factors causing obesity besides the conventional ones of diet and physical activity could be identified and acted upon. The present study investigates whether there is a link between low sleep quality and obesity in a tri-ethnic, cross-sectional sample (n = 383) of male and female adolescents ages 11-16 years old (Heartfelt Study). Sleep quality was expressed as two variables, total sleep time and sleep disturbance time obtained by 24-hour wrist actigraphy. Percent body fat and body mass index (BMI) were used together to define obesity. The potential influence of demographic and behavioral confounders were considered in models that described the relation of sleep to obesity occurrence. Obese adolescents experienced less sleep than nonobese adolescents (P < 0.01). For each hour of lost sleep, the odds of obesity increased by 80%. Sleep disturbance was not directly related to obesity in the sample, but influenced physical activity level (P < 0.01). Daytime physical activity diminished by 3% for every hour increase in sleep disturbance. The above observations were independent of potential confounding variables. Inadequate and poor sleep quality in adolescents may be important factors to consider in the prevention of childhood obesity. Am. J. Hum. Biol. 14:762-768, 2002. (C) 2002 Wiley-Liss, Inc.
