To review literature on night eating syndrome (NES) and body mass index (BMI, kg/m) published in the last 5 years.
Since December, 2013, 11 studies examined the association between NES and BMI. Five of these studies reported a positive relationship, five showed no relationship, and one produced mixed findings. Emotional eating and age were moderators. Twelve studies examined whether there was a difference in BMI between those with and without NES with only five of these finding differences. A primary weakness of the recent literature base is that it is almost entirely cross-sectional. Recent findings regarding the relationship between NES and BMI are mixed. Future research should examine the relationship between these variables longitudinally and continue to examine moderating variables that explain why some individuals manifest excess weight with NES and others do not.
回顾过去 5 年中关于夜间进食综合征（NES）和体重指数（BMI，kg/m）的文献。
自 2013 年 12 月以来，已有 11 项研究检查了 NES 与 BMI 之间的关联。其中 5 项研究报告存在正相关，5 项研究表明无关系，1 项研究结果混杂。情绪性进食和年龄是调节因素。有 12 项研究检查了患有和不患有 NES 的个体之间 BMI 是否存在差异，其中只有 5 项研究发现存在差异。最近文献基础的一个主要弱点是，它几乎完全是横断面的。关于 NES 和 BMI 之间关系的最新发现是混杂的。未来的研究应该纵向检查这些变量之间的关系，并继续检查解释为什么一些个体表现出 NES 伴发超重而另一些个体没有的调节变量。
