Loss of control (LOC) eating is a salient indicator of eating disorder psychopathology in adolescents and is associated with marked distress. While research has focused on the relevance of episode size, clinical significance of LOC eating frequency has rarely been explored. Therefore, this study aimed at identifying LOC eating prevalence with respect to its recurrence and associated variables in a community-based sample.
Participants were 1,643 adolescents, aged 12-20 years (62.4% female). Based on EDE-Q self-report, participants were categorized as those reporting recurrent (N = 156; 9.5%), nonrecurrent (N = 226; 13.8%), and no LOC eating (N = 1261; 76.7%).
Adolescents with recurrent LOC eating reported clinically relevant and significantly greater eating disorder psychopathology, functional impairment, and distress because of LOC eating, and a significantly higher body mass index (BMI, kg/m(2) ) than adolescents with nonrecurrent and those without LOC eating.
These results underline that LOC eating is a common eating behavior among adolescents in the community associated with clinical characteristics of eating disorders, and could therefore be a risk factor for developing full- or partial-syndrome eating disorders. Further research on the classification of eating disorders in adolescents with LOC eating and severity indicators is warranted.
失控性进食是青少年饮食失调心理病理学的一个显著指标，且与明显的痛苦相关。虽然研究集中在发作规模的相关性上，但失控性进食频率的临床意义很少被探讨。因此，本研究旨在确定基于社区样本的失控性进食患病率及其复发情况和相关变量。
参与者为1643名年龄在12至20岁之间的青少年（女性占62.4%）。根据饮食失调问卷（EDE-Q）自我报告，参与者被分为报告复发性失控性进食者（N = 156；9.5%）、非复发性失控性进食者（N = 226；13.8%）和无失控性进食者（N = 1261；76.7%）。
与非复发性和无失控性进食的青少年相比，复发性失控性进食的青少年报告了临床上相关且明显更严重的饮食失调心理病理学、功能损害以及因失控性进食而产生的痛苦，且体重指数（BMI，kg/m²）显著更高。
这些结果强调，失控性进食是社区青少年中一种常见的饮食行为，与饮食失调的临床特征相关，因此可能是发展为完全或部分综合征饮食失调的一个风险因素。有必要对有失控性进食的青少年饮食失调分类和严重程度指标进行进一步研究。
