Eating Disorder Not Otherwise Specified (EDNOS) constitute the most common eating disorder among those seeking treatment at eating disorder facilities; they are even more common among persons with eating disorders the community. This study compares the impact of applying the revised diagnostic criteria proposed by the DSM-5 workgroup, and the broad categories for the diagnosis of eating disorders (BCD-ED) proposed by Walsh and Sysko on the prevalence of EDNOS.
In two nationwide epidemiological studies the prevalence of eating disorders among female high school (n = 2,028) and university students (n = 1,020) was examined using DSM-IV criteria. We used a two-stage design, administering a questionnaire in the first stage and an interview in the second stage.
In the combined samples 118 cases of eating disorders (DSM-IV) were detected, of which 86 were diagnosed as EDNOS (72.9%). Application of the DSM-5 criteria reduced the number of EDNOS cases to 60 (50.8%) or to 52 (44%), when using a BMI <18.5 as cutoff for "significantly low weight" criterion in AN; with the use of BCD-ED criteria, only 5 (4.2%) cases of EDNOS remained.
Proposed criteria set for DSM-5 substantially reduce the number of EDNOS cases. However, the BCD-ED scheme further reduces its proportion, almost eliminating it.
未在其他地方特别指明的饮食失调症（EDNOS）是在饮食失调症治疗机构中寻求治疗的最常见的饮食失调症；它们在社区中患有饮食失调症的人中更为常见。本研究比较了应用 DSM-5 工作组提出的修订诊断标准和 Walsh 和 Sysko 提出的用于诊断饮食失调症的广泛类别（BCD-ED）对 EDNOS 患病率的影响。
在两项全国性的流行病学研究中，使用 DSM-IV 标准检查了女性高中（n=2028）和大学生（n=1020）的饮食失调症患病率。我们使用了两阶段设计，在第一阶段进行问卷调查，在第二阶段进行访谈。
在合并样本中，共检测到 118 例饮食失调症（DSM-IV）病例，其中 86 例被诊断为 EDNOS（72.9%）。应用 DSM-5 标准将 EDNOS 病例数减少至 60 例（50.8%）或 52 例（44%），当使用 BMI<18.5 作为 AN 中“明显低体重”标准的截止值时；使用 BCD-ED 标准，仅剩下 5 例（4.2%）EDNOS 病例。
为 DSM-5 提出的标准集大大减少了 EDNOS 病例数。然而，BCD-ED 方案进一步降低了其比例，几乎将其消除。
