Binge eating has been associated with increased hunger, suggesting a role for impaired appetite regulation. Ecological momentary assessment (EMA) is ideally suited to examine whether hunger is a precipitant of binge eating but results from such studies have not been systematically reviewed. This study provides a meta-analysis of EMA studies that have examined hunger as an antecedent of binge eating.
Electronic database and manual searches produced seven EMA studies with N = 180 participants. Meta-analyses were conducted to compare: (1) pre-binge eating hunger to average ratings of hunger, and (2) pre-binge eating hunger to hunger before regular eating.
Across studies, hunger was significantly greater before binge eating compared with average hunger ratings, but was significantly lower before binge eating compared with before other eating episodes.
Excessive hunger does not appear to be a precipitant of binge eating because higher levels of hunger are observed before regular eating episodes. However, lower hunger before food consumption may contribute to the experience of a particular eating episode as a binge.
暴食与饥饿感增加有关，这表明食欲调节受损。 生态瞬时评估（EMA）非常适合检查饥饿是否是暴食的诱因，但此类研究的结果尚未得到系统审查。 本研究对检查饥饿作为暴食前因的 EMA 研究进行了荟萃分析。
电子数据库和手动搜索共产生了七项 EMA 研究，共有 180 名参与者。 进行了荟萃分析以比较：（1）暴食前的饥饿与平均饥饿评分，以及（2）暴食前的饥饿与正常进食前的饥饿。
在所有研究中，暴食前的饥饿感明显高于平均饥饿感，但明显低于暴食前的其他进食时间点。
过度饥饿似乎不是暴食的诱因，因为在正常进食时间点前观察到更高水平的饥饿感。 然而，进食前的饥饿感降低可能导致特定进食时间点被体验为暴食。
