Rationale: Global Leadership Initiative on Malnutrition (GLIM) uses combination of different phenotypic and etiologic criteria to identify malnutrition in patients. Very few studies have analysed the major contributing factors that determines prevalence of malnutrition using GLIM criteria. Hence, the aim of this study was to calculate 6 different combinations of GLIM criteria and determine the factor that majorly contributes to identification of malnutrition.

Methods: A study was conducted in 1223 (531 females) patients with mean age of 58.0±16.5 years from a tertiary care hospital. Phenotypic criteria included: weight loss (WL), low body mass index (BMI), low calf circumference (CC) whereas etiological criteria included low food intake (FI) and high C-reactive protein (CRP). GLIM criteria were determined as GLIM 1: WL + low FI; GLIM 2: WL + high CRP; GLIM 3: low BMI + low FI, GLIM 4: low BMI + high CRP; GLIM 5: low CC + low FI; GLIM 6: low CC + high CRP; GLIM 7 (overall): WL and/or low BMI and/or low CC + low FI and/or high CRP.

Results: Based on GLIM criteria, 21.5% were normal, 60.9% had mild to moderate malnutrition and 17.6% had severe malnutrition. Based on various etiologic and phenotype combinations, prevalence of malnutrition was 10.7%, 11.9%, 9.9%, 11.7%, 44.1% and 51.5% for GLIM 1, GLIM 2, GLIM 3, GLIM 4, GLIM 5 and GLIM 6 respectively. Overall prevalence of malnutrition for GLIM 7 was 62.3%. Highest prevalence of malnutrition was observed in GLIM 5 and GLIM 6 based on etiological factor combinations with low calf circumference.

Conclusion: Calf-circumference which is the surrogate marker for low muscle mass has the maximum impact on identification of malnutrition using GLIM criteria. It is thus essential to include muscle mass in the identification of malnutrition for patients admitted in hospital.
