Loss of control (LOC) eating in youth is associated cross-sectionally with eating-related and psychosocial distress and is predictive of excessive weight gain. However, few longitudinal studies have examined the psychological impact and persistence of pediatric LOC eating. We administered the Eating Disorder Examination and self-reported measures of depressive and anxiety symptoms to 195 boys and girls (mean age = 10.4 years, SD = 1.5) at baseline and again 4.7 years (SD = 1.2) later to 118 of these youth. Missing data were imputed. Baseline report of LOC was associated with the development of partial- or full-syndrome binge eating disorder (p = .03), even after accounting for the contribution of sex, race, baseline characteristics (age, disordered eating attitudes, and mood symptoms), body mass index growth between baseline and follow-up, and years in study. Half (52.2%; 95% CI [1.15, 6.22]) of children who endorsed experiencing LOC at baseline reported persistence of LOC at follow-up (p = .02). Compared with children who never reported LOC eating or reported LOC only at baseline, those with persistent LOC experienced significantly greater increases in disordered eating attitudes (ps < .001) and depressive symptoms (p = .027) over time. These data suggest that LOC eating in children is a problematic behavior that frequently persists into adolescence and that persistent LOC eating is associated with worsening of emotional distress.
青少年时期的失控性进食与进食相关和心理社会困扰有关，并且可以预测过度体重增加。然而，很少有纵向研究探讨儿科失控性进食的心理影响和持续性。我们对 195 名男孩和女孩（平均年龄=10.4 岁，标准差=1.5）进行了饮食失调检查和自我报告的抑郁和焦虑症状测量，其中 118 名青少年在 4.7 年后（标准差=1.2）再次进行了这些测量。缺失数据采用插补法处理。基线时报告的失控性进食与部分或完全综合征暴食障碍的发展相关（p=.03），即使在考虑了性别、种族、基线特征（年龄、饮食失调态度和情绪症状）、基线和随访之间的体重指数增长以及研究年限的影响后也是如此。一半（52.2%；95%置信区间[1.15，6.22]）在基线时报告经历过失控性进食的儿童在随访时报告持续存在失控性进食（p=.02）。与从未报告过失控性进食或仅在基线时报告过失控性进食的儿童相比，持续存在失控性进食的儿童在饮食失调态度（p<.001）和抑郁症状（p=.027）方面的显著增加。这些数据表明，儿童时期的失控性进食是一种常见的行为问题，经常持续到青春期，并且持续存在的失控性进食与情绪困扰的恶化有关。
