越来越多的证据支持睡眠时间短作为体重增加和肥胖的独立风险因素的作用。本研究的目的是探讨欧洲青少年睡眠时间和饮食质量之间的关系。样本包括1522名青少年（年龄12.5-17.5岁），他们参加了欧洲多中心横断面“欧洲青少年营养健康生活方式”研究。睡眠时间是通过自我报告的问卷来估计的。通过两次24小时回忆评估膳食摄入量。青少年膳食质量指数（DQI-AM）用于计算总体膳食质量，考虑膳食平衡，膳食多样性，膳食质量和膳食指数的组成部分。平均睡眠时间>= 9小时被归类为最佳，8至9小时之间被归类为临界不足，
Evidence has grown supporting the role for short sleep duration as an independent risk factor for weight gain and obesity. The purpose of the present study was to examine the relationship between sleep duration and dietary quality in European adolescents. The sample consisted of 1522 adolescents (aged 12.5-17.5 years) participating in the European multi-centre cross-sectional 'Healthy Lifestyle in Europe by Nutrition in Adolescence' study. Sleep duration was estimated by a self-reported questionnaire. Dietary intake was assessed by two 24 h recalls. The Diet Quality Index for Adolescents with Meal index (DQI-AM) was used to calculate overall dietary quality, considering the components dietary equilibrium, dietary diversity, dietary quality and a meal index. An average sleep duration of >= 9 h was classified as optimal, between 8 and 9 h as borderline insufficient and
