China Nutrition Fundamental Data 2020

For the diagnosis of malnutrition, we adopted the Global Leadership Initiative on Malnutrition (GLIM) scheme based on three phenotypic criteria (non-volitional weight loss, low body mass index, and reduced muscle mass) and two etiologic criteria (reduced food intake or assimilation, and inflammation or disease burden). To diagnose malnutrition at least one phenotypic criterion and one etiologic criterion should be present in patients with nutritional risk.
