Emerging prospective evidence from mixed samples, mostly covering short-term follow-up periods, suggests that childhood loss of control (LOC) eating predicts significant impairment in mental and physical health. This study sought to investigate the natural course of childhood LOC eating over the long term and in relation to binge-eating disorder (BED) diagnosis, psychopathology, and body weight trajectory in the community.
A total of 60 children (8-13 years) with LOC eating within the past 3 months and 60 demographically matched children without LOC history were assessed with the Eating Disorder Examination adapted for Children and self-report questionnaires over a 5.5 year follow-up period. Missing data were imputed.
Over follow-up, 38.3% of children showed persistent LOC eating, and 28.3% revealed an onset of LOC eating. Persistent LOC eating significantly predicted onset of partial-/full-syndrome BED at follow-up. Negative prognostic effects on eating disorder psychopathology, depressive symptoms, and body mass index were nonsignificant.
The results indicate a moderate stability of LOC eating over the long term. LOC eating, especially if stable, was suggested as a variable risk factor of clinically relevant eating disturbances. In contrast, a prognostic value for psychopathology and body mass index was not confirmed.
混合样本中出现的新的前瞻性证据，主要涵盖短期随访期，表明儿童时期的失控性进食（LOC）会显著影响心理健康和身体健康。本研究旨在调查儿童时期 LOC 进食在长期内的自然发展过程，以及与暴食障碍（BED）诊断、精神病理学和体重轨迹的关系。
共有 60 名在过去 3 个月内存在 LOC 进食的儿童（8-13 岁）和 60 名无 LOC 进食史的年龄匹配儿童接受了儿童饮食障碍检查和自我报告问卷的评估，随访期为 5.5 年。缺失数据采用插补法进行处理。
在随访期间，38.3%的儿童表现出持续的 LOC 进食，28.3%的儿童出现了 LOC 进食的发作。持续的 LOC 进食显著预测了随访时部分/完全综合征 BED 的发作。对饮食障碍精神病理学、抑郁症状和体重指数的负向预后作用无统计学意义。
研究结果表明 LOC 进食在长期内具有中等稳定性。LOC 进食，特别是如果持续存在，被认为是临床相关进食障碍的一个可变风险因素。相比之下，精神病理学和体重指数的预后价值并未得到证实。
