Specific characteristics of sleep (e.g., duration, quality, and fatigue) are positively associated with (ED) behaviors, specifically binge eating (BE) potentially through decreased self-regulation and increased appetite. However, prior work has been largely cross-sectional and has not examined temporal relationships between sleep characteristics and next-day ED behaviors. Thus, the present study examined daily relationships between sleep and ED behaviors among individuals with binge-spectrum EDs.
Participants (N = 96) completed 7 daily ecological momentary assessment (EMA) surveys over 7-14 days; morning surveys assessed sleep characteristics and 6 randomly timed surveys each day captured ED behaviors. Analyses examined within-subject and between-subject effects of sleep quality, duration, and fatigue on BE, compensatory purging behaviors, and maladaptive exercise.
Within-subject sleep quality was significantly negatively associated with engagement in maladaptive exercise later that day. Additionally, between-subject sleep duration was significantly negatively associated with engagement in compensatory purging behaviors.
Within- and between-subjects associations between sleep quality and duration and compensatory behavior engagement indicate that sleep plays an important role in ED behaviors. Future research should incorporate sensor-based measurement of sleep and examine how specific facets of sleep impact BE and treatment response.

睡眠的特定特征（如持续时间、质量和疲劳程度）与进食障碍（ED）行为呈正相关，特别是暴饮暴食（BE），这可能是通过自我调节能力下降和食欲增加实现的。然而，先前的研究大多是横断面研究，并未考察睡眠特征与次日进食障碍行为之间的时间关系。因此，本研究考察了患有暴食谱系进食障碍的个体中睡眠与进食障碍行为之间的每日关系。
参与者（N = 96）在7至14天内完成了7次每日生态瞬时评估（EMA）调查；早晨的调查评估睡眠特征，每天6次随机定时调查记录进食障碍行为。分析考察了睡眠质量、持续时间和疲劳程度对暴饮暴食、代偿性清除行为和适应不良运动的个体内效应和个体间效应。
个体内睡眠质量与当天晚些时候的适应不良运动显著负相关。此外，个体间睡眠持续时间与代偿性清除行为显著负相关。
睡眠质量和持续时间与代偿行为之间的个体内和个体间关联表明，睡眠在进食障碍行为中起重要作用。未来的研究应纳入基于传感器的睡眠测量，并考察睡眠的特定方面如何影响暴饮暴食和治疗反应。
