目的：虽然体重增加与饮食失调（如神经性贪食症和暴食症）之间的关系已经确立，但超重或肥胖与以饮食限制和/或体重减轻为特征的饮食失调（如神经性厌食症（AN））之间的关系尚不清楚。方法：为了解寻求治疗的限制性饮食障碍青少年中超重或肥胖史的患病率，对2007年1月至2013年7月在一家专业饮食障碍诊所就诊的所有9-22岁的新患者进行了一项回顾性队列研究，这些患者被诊断为神经性厌食症或饮食障碍，没有其他特征，以体重减轻和/或饮食限制为特征。结果：179名青少年中，有36.7%的人的身体质量指数（BMI）高于第85百分位。BMI史高于第85百分位的患者在就诊时BMI下降幅度较大（p < 0.0001），就诊前病程较长（p < 0.0001）。身体症状的数量和饮食失调的严重程度没有差异。结论：研究结果表明，有超重或肥胖史的青少年占寻求治疗的限制性饮食失调青少年的很大一部分，强调了青少年的极端体重减轻是不健康的，无论最终体重在理论上是否在健康范围内。因为有超重史的青少年饮食失调需要更长的时间才能被发现，因此他们的预后可能更差。(C) 2015年青少年健康和医学协会。版权所有。
Purpose: Although the relationship between increased body weight and eating disorders such as bulimia nervosa and binge eating disorder is well established, the relationship between overweight or obesity and eating disorders characterized by dietary restriction and/or weight loss such as anorexia nervosa (AN) is less well known.Methods: To understand the prevalence of a history of overweight or obesity among treatment-seeking adolescents with restrictive eating disorders, a retrospective cohort study was conducted on all new patients aged 9-22 years diagnosed with either anorexia nervosa or eating disorder not otherwise specified characterized by weight loss and/or dietary restriction, seen in a specialty eating disorder clinic from January 2007 to July 2013.Results: Of 179 adolescents, 36.7% were found to have a body mass index (BMI) history above the 85th percentile. Patients with a BMI history above the 85th percentile had a larger BMI decrease at presentation (p < .0001) and a longer duration of illness before presentation (p < .0001). There were no differences in the number of physical symptoms or eating disorder severity.Conclusions: Findings suggest that adolescents with a history of overweight or obesity represent a substantial portion of treatment-seeking adolescents with restrictive eating disorders, underscoring that extreme weight loss in adolescents is not healthy, regardless of whether the end weight is theoretically within a healthy range. Because eating disorders in adolescents who have history of overweight take longer to be identified, they consequently may have a poorer prognosis.
