研究目的：探讨青少年队列中睡眠时间与能量消耗的关系。（平均年龄17.7 ± 0.4岁）。测量和结果每天24小时食物回忆问卷和腕动计测量睡眠时间被用来测试假设，较短的工作日睡眠时间（< 8小时）与营养摄入量的改变有关。营养参数包括总热量、膳食和零食的热量以及脂肪和碳水化合物的热量摄入比例。与平日平均睡眠8小时或以上的青少年相比，睡眠不足8小时的青少年从脂肪中消耗的热量比例更高（35.9% ± 6.7% vs 33.2% ± 6.9%;平均值± SD; P = 0.004），碳水化合物的热量比例较低（49.6% ± 8.2% vs 53.3% ± 8.3%; P = 0.001）。在调整了潜在的混杂因素后，睡眠时间缩短与平均每天从脂肪消耗的卡路里增加2.2个百分点和平均每天从碳水化合物消耗的卡路里减少3.0个百分点显著相关。在未经调整的分析中，较短的睡眠时间也与2.1倍增加的几率（95%置信区间：1.03，4.44），每天消耗475或更多的kcal从snacks.ConclusionQuantitative措施的大量营养素的摄入量在青少年与客观测量的睡眠时间。睡眠时间短可能会增加肥胖的风险，因为它会导致饮食模式的微小变化，从而累积改变能量平衡。
Study ObjectivesTo investigate the relation between sleep duration and energy consumption in an adolescent cohort.DesignCross-sectional.SettingFree-living environment.ParticipantsTwo hundred forty adolescents (mean age 17.7 ± 0.4 years).Measurements and ResultsDaily 24-hour food-recall questionnaires and wrist-actigraphy measurements of sleep duration were employed to test the hypothesis that shorter weekday sleep duration (< 8 h) is associated with altered nutrient intake. Nutrition parameters included total calories, calories from meals and snacks, and proportions of caloric intake from fat and carbohydrates. Compared with adolescents sleeping 8 or more hours on average on weekdays, those sleeping less than 8 hours consumed a higher proportion of calories from fats (35.9% ± 6.7% vs 33.2% ± 6.9%; mean ± SD; P = 0.004) and a lower proportion of calories from carbohydrates (49.6% ± 8.2% vs 53.3% ± 8.3%; P = 0.001). After adjusting for potential confounders, shorter sleep duration was significantly associated with an average daily increase of calories consumed from fat of 2.2 percentage points and an average daily decrease in percentage of calories from carbohydrates of 3.0 percentage points. In unadjusted analyses, shorter sleep duration was also associated with a 2.1-fold increased odds (95% confidence interval: 1.03, 4.44) of daily consuming 475 or more kcal from snacks.ConclusionQuantitative measures of macronutrient intake in adolescents were associated with objectively measured sleep duration. Short sleep duration may increase obesity risk by causing small changes in eating patterns that cumulatively alter energy balance.
