Previous research revealed that people who did not meet full DSM-IV criteria for anorexia nervosa (AN), bulimia nervosa (BN), or binge-eating disorder (BED) but met criteria for eating disorder not otherwise specified (EDNOS) display high levels of psychiatric and physical morbidity commensurate with full criteria eating disorders. The DSM-5 introduced significant changes to eating disorder diagnostic criteria, so the present study aimed to determine whether the revised diagnostic criteria better distinguish between full criteria eating disorders, and other specified feeding or eating disorder (OSFED) and unspecified feeding or eating disorder (UFED). We present a series of meta-analyses comparing eating pathology, general psychopathology, and physical health impairments among those with AN, BN, and BED, compared to those with OSFED or UFED (n = 69 eligible studies). Results showed significantly more eating pathology in OSFED compared to AN, no difference in general psychopathology, and greater physical health impairments in AN. BN had greater eating pathology and general psychopathology than OSFED, but OSFED showed more physical health impairments. No differences were found between BN and purging disorder or low-frequency BN, or between BED and OSFED. Findings highlight the clinical severity of OSFED and suggest the DSM-5 criteria may not appropriately account for these presentations.

先前的研究表明，不符合 DSM-IV 神经性厌食症 (AN)、神经性贪食症 (BN) 或暴食症 (BED) 标准但符合未另行规定的进食障碍 (EDNOS) 标准的人表现出高水平与完全标准饮食失调相称的精神和身体发病率。DSM-5 对进食障碍诊断标准进行了重大更改，因此本研究旨在确定修订后的诊断标准是否能更好地区分完整标准进食障碍、其他特定的进食或进食障碍 (OSFED) 和未特定的进食或进食障碍 ( UFED）。我们提出了一系列荟萃分析，比较患有 AN、BN 和 BED 的人与患有 OSFED 或 UFED 的人的饮食病理学、一般精神病理学和身体健康障碍（n  = 69 项符合条件的研究）。结果显示，与 AN 相比，OSFED 的饮食病理明显更多，一般精神病理学没有差异，AN 的身体健康损害更大。BN 比 OSFED 有更多的饮食病理和一般精神病理学，但 OSFED 表现出更多的身体健康障碍。BN 和清除障碍或低频 BN 之间，或 BED 和 OSFED 之间没有发现差异。调查结果突出了 OSFED 的临床严重性，并表明 DSM-5 标准可能无法恰当地解释这些表现。
