Loss of Control Eating Disorder (LOC-ED) has been proposed as a diagnostic category for children 6-12years with binge-type eating. However, characteristics of youth with LOC-ED have not been examined. We tested the hypothesis that the proposed criteria for LOC-ED would identify children with greater adiposity, more disordered eating attitudes, and greater mood disturbance than those without LOC-ED. Participants were 251 youth (10.29years±1.54, 53.8% female, 57.8% White, 35.5% Black, 2.0% Asian, 4.8% Hispanic, 53.0% overweight). Youth were interviewed regarding eating attitudes and behaviors, completed questionnaires to assess general psychopathology, and underwent measurements of body fat mass. Using previously proposed criteria for LOC-ED, children were classified as LOC-ED (n=19), LOC in the absence of the full disorder (subLOC, n=33), and youth not reporting LOC (noLOC, n=199). LOC-ED youth had higher BMIz (p=0.001) and adiposity (p=0.003) and reported greater disordered eating concerns (p<0.001) compared to noLOC youth. Compared to subLOC youth, LOC-ED youth had non-significantly higher BMIz (p=0.11), and significantly higher adiposity (p=0.04) and disordered eating attitudes (p=0.02). SubLOC youth had greater disordered eating concerns (p<0.001) and BMIz (p=0.03) but did not differ in adiposity (p=0.33) compared to noLOC youth. These preliminary data suggest that LOC-ED youth are elevated on disordered eating cognitions and anthropometric measures compared to youth without LOC-ED. Longitudinal studies are needed to determine if those with LOC-ED are at particularly increased risk for progression of disordered eating and excess weight gain.
失控性饮食失调（LOC-ED）已被提议作为6至12岁有暴饮暴食型饮食行为儿童的一个诊断类别。然而，患有LOC-ED的青少年的特征尚未得到研究。我们检验了这样一个假设：LOC-ED的拟议标准将识别出比没有LOC-ED的儿童有更高肥胖程度、更紊乱的饮食态度和更严重情绪障碍的儿童。参与者为251名青少年（年龄10.29岁±1.54，53.8%为女性，57.8%为白人，35.5%为黑人，2.0%为亚洲人，4.8%为西班牙裔，53.0%超重）。就饮食态度和行为对青少年进行了访谈，完成了评估一般精神病理学的问卷，并进行了身体脂肪量测量。根据先前提出的LOC-ED标准，将儿童分为LOC-ED组（n = 19）、存在部分症状但未达到完全紊乱的LOC组（亚LOC组，n = 33）和未报告有LOC的青少年组（无LOC组，n = 199）。与无LOC组青少年相比，LOC-ED组青少年的BMIz更高（p = 0.001）、肥胖程度更高（p = 0.003），且报告有更紊乱的饮食问题（p < 0.001）。与亚LOC组青少年相比，LOC-ED组青少年的BMIz略高（p = 0.11），肥胖程度显著更高（p = 0.04），饮食态度紊乱程度更高（p = 0.02）。与无LOC组青少年相比，亚LOC组青少年有更紊乱的饮食问题（p < 0.001）和更高的BMIz（p = 0.03），但肥胖程度无差异（p = 0.33）。这些初步数据表明，与没有LOC-ED的青少年相比，LOC-ED组青少年在饮食认知紊乱和人体测量指标方面更为突出。需要进行纵向研究以确定患有LOC-ED的青少年是否在饮食紊乱和体重过度增加方面有特别高的进展风险。
