Metabolic/bariatric surgery (MBS) is the most effective treatment for obesity, yet many factors influence successful individual weight loss. Among those are a variety of health behaviors that are assessed in the process of presurgical psychological evaluations, including eating pathology and sleep disturbance (both of which are relatively common among surgical candidates).
This study aims to examine the relationship between sleep, binge eating, and night eating behaviors among individuals seeking MBS.

Patients (N = 311) seeking presurgical psychological evaluations for bariatric surgery completed self-report measures. Of these, 83.0% were females and 70.7% of those with ethnicity data identified as White. Average body mass index (BMI) in the sample was 46.5 (standard deviation [SD] = 8.02). Correlations between variables were calculated and examination of the indirect effect of sleep disturbance on night eating as mediated by binge eating was conducted.
Sleep disturbance, binge eating, and night eating were significantly associated (b = .22-.45). Mediation analysis yielded a significant indirect effect, indicating that binge eating propensity explains the relationship between impaired sleep and night eating symptoms (b = .09, standard error [SE] = .03, confidence interval [CI]: .04-.18).
The observed relationship between sleep disturbance, night eating, and binge eating among bariatric candidates provides implications for future research and treatment approaches. Specifically, additional attention to sleep disturbance in the presurgical assessment process and consideration of sleep hygiene as a potential target for intervention may facilitate improvements in overall health, adjustment, and sustained weight loss.
代谢/减重手术（MBS）是治疗肥胖症最有效的方法，但许多因素会影响个体成功减肥。其中包括在术前心理评估过程中评估的各种健康行为，包括饮食失调和睡眠障碍（这两者在手术候选人中都比较常见）。
本研究旨在研究寻求 MBS 的个体中睡眠、暴食和夜间进食行为之间的关系。

接受减重手术术前心理评估的患者（N=311）完成了自我报告量表。其中，83.0%为女性，70.7%有民族数据的患者被认定为白人。样本的平均身体质量指数（BMI）为 46.5（标准差[SD]=8.02）。计算了变量之间的相关性，并对睡眠障碍通过暴食行为对夜间进食的间接影响进行了检验。
睡眠障碍、暴食和夜间进食行为显著相关（b=0.22-0.45）。中介分析产生了显著的间接效应，表明暴食倾向解释了睡眠受损与夜间进食症状之间的关系（b=0.09，标准误[SE]=0.03，置信区间[CI]：0.04-0.18）。
在接受减重手术的候选人中观察到的睡眠障碍、夜间进食和暴食之间的关系为未来的研究和治疗方法提供了启示。具体而言，在术前评估过程中额外关注睡眠障碍，并考虑将睡眠卫生作为潜在的干预目标，可能会改善整体健康、调整和持续的体重减轻。
