The classification for underweight adults, defined as a body mass index (BMI; <18.5 kg/m²) by the World Health Organization (WHO), has been consistent globally with respect to populations. Although the WHO has recognized that body composition and health risks differ according to ethnicity by offering adjusted BMI cut-offs for overweight and obesity (23-24.9 kg/m² for overweight and ≥25 kg/m² for obesity) in Asian-populations, the underweight threshold has strangely not been modified. Because there is evidence of unique physiological and metabolic profiles of Asian populations the applicability of this uniformity to Asian populations remains as an important question.
世界卫生组织（WHO）将体重不足的成年人定义为身体质量指数（BMI；<18.5 kg/m²），全球范围内对人群的这一分类标准是一致的。尽管WHO已经认识到，根据种族不同，身体成分和健康风险存在差异，因此针对亚洲人群提供了超重和肥胖的BMI调整临界值（超重为23-24.9 kg/m²，肥胖为≥25 kg/m²），但奇怪的是，体重不足的临界值并未修改。由于有证据表明亚洲人群具有独特的生理和代谢特征，这种统一标准对亚洲人群的适用性仍然是一个重要问题。
