Atypical anorexia nervosa (atypical AN) appears to be a heterogeneous disorder under the current diagnostic system. Though the body mass index (BMI) cutoff point of 18.5 kg/m is a criterion that distinguishes atypical AN from AN, the cutoff may not be universally applicable as the norms for BMI vary and can be affected by several factors, including cross-country differences and social determinants. It is unfortunate that we do not yet have reliable or widely available criteria other than BMI for the diagnosis of atypical AN. Additional relevant markers of atypical AN are needed in future diagnostic systems.
在当前诊断体系下，非典型神经性厌食症（非典型AN）似乎是一种异质性疾病。尽管体重指数（BMI）18.5kg/m²的切点是区分非典型AN与AN的一个标准，但由于BMI的标准存在差异且会受到多种因素影响，包括国家间差异和社会决定因素，该切点可能并非普遍适用。遗憾的是，除BMI外，我们尚无可靠或广泛可用的标准来诊断非典型AN。未来的诊断体系需要非典型AN的其他相关标志物。
