研究目的：为了研究睡眠和饮食摄入量之间的关系，在青少年使用实验性睡眠限制protocol.Design：随机交叉睡眠限制-扩展paradigm。设置：睡眠获得和监测在家里，饮食测量在办公室访问。参与者：41个典型的发展青少年年龄14-16岁。干预措施：为期3周的方案包括一个旨在稳定昼夜节律的基线周，随后随机连续5晚限制睡眠（周一至周五在床上睡6.5小时）与健康睡眠时间（卧床10小时），2晚洗脱期，5晚交叉期。测量：通过活动记录仪监测睡眠，青少年在每个实验条件下完成经过验证的24小时饮食回忆访谈。配对样本t检验检查了关键常量营养素消费条件和饮食类别选择之间的差异。与健康的睡眠条件相比，睡眠受限的青少年饮食的特点是血糖指数和血糖负荷较高，热量和碳水化合物的趋势更多，脂肪或蛋白质的消耗没有差异。探索性分析显示，在睡眠限制比健康sleep.Conclusions：慢性睡眠限制在青春期的消费显着更多的甜点和糖果似乎会导致增加消费的食物与高血糖指数，特别是甜点/糖果。青春期常见的慢性睡眠限制可能会导致饮食行为的改变，从而增加肥胖和相关发病率的风险。
Study Objective: To examine the relationship between sleep and dietary intake in adolescents using an experimental sleep restriction protocol.Design: Randomized crossover sleep restriction-extension paradigm.Setting: Sleep obtained and monitored at home, diet measured during an office visit.Participants: Forty-one typically developing adolescents age 14-16 years.Interventions: The 3-week protocol consisting of a baseline week designed to stabilize the circadian rhythm, followed randomly by 5 consecutive nights of sleep restriction (6.5 hours in bed Monday-Friday) versus healthy sleep duration (10 hours in bed), a 2-night washout period, and a 5-night crossover period.Measurements: Sleep was monitored via actigraphy and teens completed validated 24-hour diet recall interviews following each experimental condition.Results: Paired-sample t-tests examined differences between conditions for consumption of key macronutrients and choices from dietary categories. Compared with the healthy sleep condition, sleep-restricted adolescents' diets were characterized by higher glycemic index and glycemic load and a trend toward more calories and carbohydrates, with no differences in fat or protein consumption. Exploratory analyses revealed the consumption of significantly more desserts and sweets during sleep restriction than healthy sleep.Conclusions: Chronic sleep restriction during adolescence appears to cause increased consumption of foods with a high glycemic index, particularly desserts/sweets. The chronic sleep restriction common in adolescence may cause changes in dietary behaviors that increase risk of obesity and associated morbidity.
