暴饮暴食在肥胖的成年人中很常见。《精神疾病诊断和统计手册》描述了暴饮暴食的5个指标(比平时吃得更快；吃到不舒服的饱为止；在身体不饿的情况下大量进食；由于对自己的进食量感到尴尬而独自进食；以及暴饮暴食后对自己感到厌恶、沮丧或非常内疚)，但它们的有效性尚不清楚。我们通过生态瞬时评估，在50名肥胖成年人中检验了这5个指标与暴饮暴食和非暴饮暴食之间的初步联系。广义线性模型显示，与非暴饮期相比，自我报告的暴饮期与发作前较低的饥饿感(p=.004)、较高的发作后饱腹感(p<；.001)、在进食前报告中度到极度羞愧的可能性更大(p<；.001)，以及在进食后报告中度到极端厌恶、抑郁和/或内疚的可能性更大(p<；.001)，但与进食速度比平时更快无关(p<；.85)。结果支持大多数暴饮暴食指标的有效性，尽管快速进食标准的实用性值得怀疑。未来的研究应该检查在暴饮暴食干预中修改这些指标是否会减少失控和/或暴饮暴食的发生。
Binge-eating is common in adults with obesity. The Diagnostic and Statistical Manual for Psychiatric Disorders describes 5 indicators of binge-eating (eating more rapidly than usual; eating until uncomfortably full; eating large amounts of food when not physically hungry; eating alone due to embarrassment over how much one is eating; and feeling disgusted with oneself, depressed, or very guilty after overeating), but their validity is unclear. We examined preliminary associations between the 5 indicators and binge versus non-binge episodes among 50 adults with obesity via ecological momentary assessment. Generalized linear models revealed that, relative to non-binge episodes, self-reported binge episodes were associated with lower pre-episode hunger (p=.004), higher post-episode fullness (p<.001), a greater likelihood of reporting moderate to extreme shame prior to eating in conjunction with eating alone (p<.001), and a greater likelihood of reporting moderate to extreme disgust, depression, and/or guilt after eating (p<.001), but not with eating more rapidly than usual (p=.85). Results support the validity of most binge-eating indicators, although the utility of the rapid eating criterion is questionable. Future research should examine whether modifying these indicators in binge-eating interventions would reduce the occurrence of loss of control and/or overeating.
