背景：睡眠不足以及高能量食品和含糖饮料 (SSB) 的摄入量增加都被认为是导致超重和肥胖患病率增加的因素。 目的：评估客观测量的睡眠时间（平均和每日变异性）以及家长报告的睡眠问题是否与提出的 8-11 岁儿童超重和肥胖的饮食风险因素独立相关。 设计：在这项横断面研究中，数据通过客观测量（体动记录仪）对 676 名表面健康的丹麦儿童进行了 8 个晚上的睡眠持续时间和睡眠持续时间的日常变异性测量，并由家长填写了儿童睡眠习惯问卷 (CSHQ)。使用基于网络的食物记录连续7天记录饮食。获取空腹血样以测量血浆瘦素和生长素释放肽水平。 结果：睡眠时间（每晚小时）与饮食能量密度 (ED) (β = -0.32 kJ g(-1))、添加糖 (β = -1.50 E%) 和 SSB (β = -1.07 E%) 呈负相关（所有 P
BACKGROUND: Lack of sleep and increased consumption of energy-dense foods and sugar-sweetened beverages (SSBs) have all been suggested as factors contributing to the increased prevalence of overweight and obesity.OBJECTIVE: To evaluate whether objectively measured sleep duration (average and day-to-day variability) as well as parent-reported sleep problems are independently associated with proposed dietary risk factors for overweight and obesity in 8-11-year-old children.DESIGN: In this cross-sectional study, data on sleep duration and day-to-day variability in sleep duration were measured in 676 Danish, apparently healthy children by an objective measure (actigraphy) for 8 nights, and the Children's Sleep Habits Questionnaire (CSHQ) was filled out by the parents. Diet was recorded using a web-based food record for 7 consecutive days. Fasting blood samples were obtained for measurements of plasma leptin and ghrelin levels.RESULTS: Sleep duration (h per night) was negatively associated with energy density (ED) of the diet (beta = -0.32 kJ g(-1)), added sugar (beta = -1.50 E%) and SSBs (beta = -1.07 E%) (all P
