目的探讨12-18岁正常体重和超重/肥胖青少年的睡眠时间、食物相关抑制控制和食物奖励之间的关系。体重状况对睡眠、抑制控制和食物奖励之间的关联的潜在调节作用也进行了研究。方法对32名正常体重青少年和32名超重/肥胖青少年（12-18岁）进行研究。参与者每晚在床上睡5小时（限制性睡眠）或每晚在床上睡9小时（习惯性睡眠），持续5个晚上，实验期间隔3周。参与者在每个研究阶段的第六天完成了与食物相关的抑制控制任务和评估食物奖励的问卷。结果重复测量的方差分析显示，青少年表现更差的食物相关的抑制控制任务，并提高了食物奖励睡眠限制。与体重正常的青少年相比，超重/肥胖的青少年表现出更高的食物奖励;体重对食物相关的抑制控制没有主要影响。睡眠状况和体重状况对食物奖励有显著的相互作用，体重正常的青少年在睡眠限制后表现出更高的食物奖励。超重/肥胖的青少年表现出一贯的高食物奖励，睡眠时间没有影响。结论：当睡眠受到限制时，青少年表现出更高的食物奖励，并且抑制对食物图像的优势反应的能力较低。体重正常的青少年经历急性睡眠限制可能会认为食物相对于正常睡眠更有益。
Objective This experimental study evaluated associations between sleep duration, food-related inhibitory control, and food reward in adolescents aged 12-18 with normal weight and overweight/obesity. The potential moderating effect of weight status on the associations between sleep, inhibitory control, and food reward was also examined. Methods Thirty-two adolescents with normal weight and 32 adolescents with overweight/obesity (ages 12-18) participated in this study. Participants spent 5 hr in bed per night (restricted sleep) or 9 hr in bed per night (habitual sleep) for five nights with experimental periods separated by 3 weeks. Participants completed a food-related inhibitory control task and a questionnaire assessing food reward on the sixth day of each study phase. Results Repeated measures analyses of variance revealed that adolescents performed more poorly on a food-related inhibitory control task and had heightened food reward following sleep restriction. Adolescents with overweight/obesity demonstrated heightened food reward compared with adolescents with normal weight; there was no main effect of weight on food-related inhibitory control. There was a significant interaction between sleep condition and weight status on food reward, with adolescents with normal weight demonstrating heightened food reward following sleep restriction. Adolescents with overweight/obesity showed consistently high food reward with no effect of sleep duration. Conclusions When sleep restricted, adolescents demonstrated heightened food reward and were less able to inhibit prepotent responses to food images. Adolescents with normal weight who experience acute sleep restriction may perceive foods to be more rewarding relative to normal sleep.
