Insufficient sleep is widespread among adolescents and has consequences that extend far beyond hampering day-to-day functioning. It may influence eating and physical activity patterns and be an important determinant of adolescent overweight/obesity status. We assessed how self-reported sleep duration on school nights was associated with weight-related behaviors (eating, diet, and physical activity) and overweight/obesity at the baseline wave (ninth grade year) of the START study ( = 2134). Fifteen percent of our sample reported optimal sleep duration (8.5-10.0 hours); nonwhites, participants of lower socioeconomic status, and girls were at greater risk for insufficient sleep. Suboptimal sleep was associated with various poor weight-related behaviors such as increased sugar-sweetened beverage consumption, decreased vegetable consumption, and decreased breakfast eating ( < 0.001). Fewer hours of sleep were also associated with less physical activity and an increased likelihood of obesity ( = 0.02 for both associations). The influence of adolescent sleep insufficiency on diet and activity could impact childhood obesity and following chronic disease risk especially if lack of sleep sets the stage for enduring, lifelong, poor, weight-related behavior patterns.
青少年普遍存在睡眠不足的问题，其影响不仅局限于日常功能障碍。它可能会影响饮食和身体活动模式，是青少年超重/肥胖状况的一个重要决定因素。我们评估了在 START 研究的基线波（九年级）中，自我报告的上学日夜间睡眠时间与与体重相关的行为（饮食、饮食和身体活动）和超重/肥胖之间的关系（n=2134）。我们的样本中有 15%的人报告了最佳睡眠时间（8.5-10.0 小时）；非白种人、社会经济地位较低的参与者和女孩更容易出现睡眠不足的情况。睡眠不足与各种不良的体重相关行为有关，例如增加含糖饮料的摄入、减少蔬菜的摄入和减少早餐的摄入（<0.001）。睡眠时间较少也与身体活动减少和肥胖的可能性增加有关（与这两种关联的关联均为=0.02）。青少年睡眠不足对饮食和活动的影响可能会影响儿童肥胖和随后的慢性疾病风险，尤其是如果睡眠不足为持久的、终身的、不良的、与体重相关的行为模式奠定了基础。
