Nighttime eating has been associated with obesity, inflammation, and poor nutritional intake, yet correlates of this behavior are understudied in pediatric populations and among adolescents in particular. The current study examines modifiable factors related to nighttime eating, including sleep parameters and regulatory abilities-as well as the interplay between these constructs-in adolescents. A total of 223 adolescents (M = 15.32 years, 52.9 % female, 15.7 % classified as overweight, 21.1 % had obesity) wore ActiGraph devices to measure sleep and were instructed to complete three 24-h dietary recall measures over a two-week period. Participants also completed self-report measures of executive function. Greater variability in sleep duration was consistently associated with higher average calorie, sugar, and fat consumption after 8, 9, and 10 PM. The main effect of global executive function on all nighttime eating measures was nonsignificant, and executive function did not moderate relationships between sleep parameters and nighttime eating measures. Since adolescents' eating habits may set the stage for lifelong dietary practices, efforts to ensure consistent sleep duration may reduce risk for nighttime eating in this nutritionally vulnerable population.
夜间进食与肥胖、炎症和营养摄入不良有关，但这种行为的相关性在儿科人群中研究不足，尤其是在青少年中。本研究探讨了与夜间进食相关的可改变因素，包括睡眠参数和调节能力，以及这些结构之间的相互作用在青少年中的关系。共有 223 名青少年（M=15.32 岁，52.9%为女性，15.7%被归类为超重，21.1%肥胖）佩戴了 ActiGraph 设备来测量睡眠，并被指示在两周内完成三次 24 小时饮食回忆测量。参与者还完成了执行功能的自我报告测量。睡眠时间的变异性越大，晚上 8 点、9 点和 10 点以后的平均卡路里、糖和脂肪摄入量就越高。总体执行功能对所有夜间进食测量的主要影响均不显著，执行功能也不能调节睡眠参数和夜间进食测量之间的关系。由于青少年的饮食习惯可能为终生的饮食实践奠定基础，因此，努力确保一致的睡眠时间可能会降低这个营养脆弱人群夜间进食的风险。
