ObjectiveThe purpose of this study was to examine the association between weight gain and eating disorder (ED) symptoms among adults receiving treatment for atypical anorexia nervosa (AAN), to determine whether those who had a higher percent of expected body weight (%EBW) at discharge exhibited lower ED symptoms than those who gained less weight, and to compare this group to a matched sample of patients with anorexia nervosa (AN).MethodParticipants were 96 adults receiving treatment at an ED treatment facility between December 2020 and May 2023. The Eating Disorder Examination‐Questionnaire (EDE‐Q) was completed at admission and discharge, and %EBW was obtained at admission and discharge.ResultsAll EDE‐Q subscale scores improved from admission to discharge for patients with AAN and patients with AN. Neither %EBW at discharge nor weight gain were associated with EDE‐Q subscale scores for those with AAN. For patients with AN, %EBW at discharge and weight gain were associated with EDE‐Q Restraint at discharge.ConclusionsWeight restoring to a higher level and gaining more weight were not associated with EDE‐Q scores at discharge for AAN. Further research is needed to determine how weight restoration using intensive treatment settings affects remission and recovery in patients with AAN.

非典型神经性厌食症患者的体重增加和饮食失调症状

目的本研究的目的是检查接受非典型神经性厌食症 (AAN) 治疗的成年人体重增加与饮食失调 (ED) 症状之间的关系，以确定那些在治疗时预期体重百分比 (%EBW) 是否较高的患者与体重增加较少的患者相比，出院的患者表现出较低的 ED 症状，并将该组与神经性厌食症 (AN) 患者的匹配样本进行比较。方法参与者是 2020 年 12 月至 2023 年 5 月期间在 ED 治疗机构接受治疗的 96 名成年人。在入院和出院时完成疾病检查问卷 (EDE-Q)，并在入院和出院时获得 %EBW。 结果 AAN 患者和 AN 患者从入院到出院，所有 EDE-Q 分量表评分均有所改善。对于 AAN 患者，出院时 %EBW 和体重增加均与 EDE-Q 子量表评分无关。对于 AN 患者，出院时 %EBW 和体重增加与出院时 EDE-Q 限制相关。结论 体重恢复到较高水平和体重增加与 AAN 出院时 EDE-Q 评分无关。需要进一步的研究来确定使用强化治疗设置的体重恢复如何影响 AAN 患者的缓解和恢复。
