Night eating syndrome is marked by substantial evening or nocturnal food intake, insomnia, morning anorexia, and depressed mood. Night eating severity has been positively associated with body mass index (BMI), binge eating frequency, and emotional eating tendencies. We conducted an online questionnaire study among students (N=729) and explored possible interactive effects between those variables. Night eating severity, binge eating frequency, BMI and emotional eating were all positively correlated with each other. Regression analyses showed that night eating severity was particularly related to more frequent binge episodes and higher BMI at high levels of emotional eating but unrelated to those variables at low levels of emotional eating. Thus, eating as a means of emotion regulation appears to be an important moderator of the relationship between night eating and both binge eating and BMI.
夜间进食综合征的特征是大量在傍晚或夜间进食、失眠、早晨厌食和情绪低落。夜间进食严重程度与体重指数（BMI）、暴食频率和情绪性进食倾向呈正相关。我们对学生（N=729）进行了在线问卷调查研究，并探讨了这些变量之间可能存在的交互作用。夜间进食严重程度、暴食频率、BMI 和情绪性进食彼此之间呈正相关。回归分析显示，夜间进食严重程度与更频繁的暴食发作和更高的 BMI 显著相关，但与情绪性进食水平较低时的这些变量无关。因此，进食作为一种情绪调节手段似乎是夜间进食与暴食和 BMI 之间关系的一个重要调节因素。
