Abstract Objective Malnutrition is common in inflammatory bowel disease (IBD) patients. The Global Leadership Initiative on Malnutrition (GLIM) was proposed to assess the severity and characteristics of malnutrition. Thus, we aimed to use the latest consensus on the diagnosis of malnutrition, GLIM criteria, to evaluate the malnutrition in IBD patients. Methods We performed a retrospective cohort study of 73 adult IBD patients (48 Crohn's disease (CD) and 25 ulcerative colitis (UC)). Demographic data, clinical characteristics, and nutrition status defined by Nutritional Risk Screening 2002 (NRS 2002) and GLIM criteria were recorded at enrollment. Results According to the GLIM criteria, 43 (58.90%) patients were identified with malnutrition, and the incidence of mild to moderate malnutrition and severe malnutrition was 28.77% (21 / 73) and 30.14% (22 / 73), respectively. The severity of malnutrition in IBD patients increased with the cumulative number of phenotypic criteria they met (P Conclusion The prevalence of malnutrition according to the GLIM criteria is high in non-surgical IBD patients, and as the degree of malnutrition worsens, more phenotypes and etiological types appear. The phenotypic and etiologic characteristics of GLIM are different in CD and UC patients.
