Other specified feeding and eating disorders (OSFED) is a diagnostic category in DSM-5 describing individuals with clinically significant eating behavioral disturbances that do not meet criteria for full-threshold eating disorder diagnoses. OSFED includes five example subgroups: atypical anorexia nervosa, sub-threshold bulimia nervosa, sub-threshold binge-eating disorder, purging disorder, and night eating syndrome. A recent review of OSFED by Dang et al. aims to examine differences between OSFED and full-threshold eating disorders as well as between OSFED and healthy populations but is limited by the lack of clear definitions of OSFED subtypes and methodological differences across studies. Clearer diagnostic definitions for OSFED subtypes are needed. Consideration should also be given to indicators of lifetime history of full-threshold conditions, diagnostic drift, and remission criteria as OSFED categories undergo further study.
其他特定的进食和摄食障碍（OSFED）是 DSM-5 中的一个诊断类别，用于描述那些具有临床显著进食行为障碍但不符合全阈值进食障碍诊断标准的个体。OSFED 包括五个示例亚组：非典型神经性厌食症、阈下神经性贪食症、阈下暴食障碍、清泻性障碍和夜间进食综合征。Dang 等人最近对 OSFED 的综述旨在检查 OSFED 与全阈值进食障碍之间以及 OSFED 与健康人群之间的差异，但受到 OSFED 亚型缺乏明确定义以及研究之间方法学差异的限制。需要为 OSFED 亚型制定更明确的诊断定义。还应考虑全阈值疾病的终身病史、诊断漂移和缓解标准等指标，因为 OSFED 类别将进一步研究。
