BACKGROUND
Inconsistent sleep patterns may promote excess weight gain by increasing food cravings and loss-of-control (LOC)-eating; however, these relationships have not been elucidated in youth.
OBJECTIVE
We tested whether sleep duration and timing were associated with food cravings and LOC-eating.
METHOD
For 14 days, youths wore actigraphy monitors to assess sleep and reported severity of food cravings and LOC-eating using ecological momentary assessment. Generalized linear mixed models tested the associations between weekly and nightly shifts in facets of sleep (i.e., duration, onset, midpoint, and waketime) and next-day food cravings and LOC-eating. Models were re-run adjusting for relevant covariates (e.g., age, sex, adiposity).
RESULTS
Among 48 youths (12.88 ± 2.69 years, 68.8% female, 33.3% with overweight/obesity), neither weekly nor nightly facets of sleep were significantly associated with food cravings (ps = 0.08-0.93). Youths with shorter weekly sleep duration (est. ß = -0.31, p = 0.004), earlier weekly midpoints (est. ß = -0.47, p = 0.010) and later weekly waketimes (est. ß = 0.49, p = 0.010) reported greater LOC-eating severity; findings persisted in adjusted models.
CONCLUSIONS
In youth, weekly, but not nightly, shifts in multiple facets of sleep were associated with LOC-eating severity; associations were not significant for food cravings. Sleep should be assessed as a potentially modifiable target in paediatric LOC-eating and obesity prevention programs.
背景
不规律的睡眠模式可能会通过增加食物渴望和失控（LOC）进食来促进体重增加；然而，这些关系在年轻人中尚未得到阐明。
目的
我们测试了睡眠时间和时间是否与食物渴望和 LOC 进食有关。
方法
在 14 天内，青少年佩戴活动监测器以评估睡眠，并使用生态瞬时评估报告食物渴望和 LOC 进食的严重程度。广义线性混合模型测试了睡眠各个方面（即持续时间、开始时间、中点和醒来时间）的每周和每晚变化与次日食物渴望和 LOC 进食之间的关联。模型在调整了相关协变量（例如年龄、性别、肥胖程度）后重新运行。
结果
在 48 名青少年（12.88±2.69 岁，68.8%为女性，33.3%超重/肥胖）中，每周和每晚的睡眠方面都与食物渴望没有显著关联（p 值=0.08-0.93）。每周睡眠持续时间较短的青少年（估计ß=-0.31，p=0.004）、每周中点较早（估计ß=-0.47，p=0.010）和每周醒来时间较晚（估计ß=0.49，p=0.010）的青少年报告的 LOC 进食严重程度更高；这些发现在调整后的模型中仍然存在。
结论
在青少年中，每周而非每晚的睡眠多个方面的变化与 LOC 进食严重程度相关；与食物渴望无关。在儿科 LOC 进食和肥胖预防计划中，应将睡眠评估为一个潜在的可改变的目标。
