This study sought to document self-reported binge eating in a large sample of severely obese children and to examine the impact of binge eating on changes in percent overweight among children randomized to family-based behavioral treatment (intervention) versus control (usual care).
As part of a larger randomized controlled trial, 192 children aged 8-12 years (M=10.2, s.d.=1.2) with a mean body mass index (BMI) percentile of 99.2 (s.d.=0.7) completed assessments at baseline and 6-, 12-, and 18 months post-randomization. A parent or guardian also participated. Child psychological symptoms, including binge eating, were measured before randomization using self-report questionnaires. Child height and weight were measured at baseline, 6-, 12-, and 18 months. The primary study outcome was percent overweight (that is, percent over median BMI for age and sex).
Twenty-two children (11.5%) endorsed binge eating at baseline (Binge Eating Group). Children in the Binge Eating Group were younger and had more depressive, anxiety, and eating disorder symptoms, and lower self-esteem than children in the rest of the sample (No Binge Eating Group). There also were differences between the Binge Eating and No Binge Eating groups with respect to the short-term effects of treatment group assignment on change in percent overweight during the study. Specifically, improvements in percent overweight in the intervention condition relative to usual care were documented in the No Binge Eating Group only. Among children in the Binge Eating Group, those assigned to intervention showed a 2.6% increase in percent overweight, on average, at the completion of acute treatment as compared to an 8.5% decrease among children without binge eating. However, these effects were not maintained during follow-up.
Results of this study suggest the importance of considering binge eating in the development of weight management programs for severely obese youth.
本研究旨在记录大量严重肥胖儿童的自我报告暴食行为，并探讨暴食行为对随机分配至家庭为基础的行为治疗（干预组）与对照组（常规护理）的儿童超重百分比变化的影响。
作为一项更大的随机对照试验的一部分，192 名 8-12 岁（M=10.2，s.d.=1.2）的儿童参与了研究，他们的平均体重指数（BMI）百分位数为 99.2（s.d.=0.7），并在随机分组后 6、12 和 18 个月完成评估。一位家长或监护人也参与了研究。在随机分组前，使用自我报告问卷评估儿童的心理症状，包括暴食行为。在基线、6、12 和 18 个月时测量儿童的身高和体重。主要研究结果是超重百分比（即年龄和性别中位数 BMI 以上的百分比）。
22 名儿童（11.5%）在基线时报告有暴食行为（暴食组）。与其余样本相比，暴食组的儿童年龄更小，抑郁、焦虑和饮食障碍症状更多，自尊心更低（无暴食组）。在治疗组对研究期间超重百分比变化的短期影响方面，暴食组和无暴食组之间也存在差异。具体而言，在无暴食组中，干预组的超重百分比改善相对常规护理有所改善。在暴食组中，与无暴食的儿童相比，干预组的儿童在急性治疗结束时平均超重百分比增加了 2.6%，而无暴食的儿童平均超重百分比减少了 8.5%。然而，这些效果在随访期间并未持续。
本研究结果表明，在为严重肥胖青少年制定体重管理计划时，考虑暴食行为是很重要的。
