Özet
Aim: Malnutrition remains a major global health challenge, particularly among older adults, where it contributes to frailty, sarcopenia, and chronic diseases.The Global Leadership Initiative on Malnutrition (GLIM) provides standardized diagnostic criteria to improve early detection.This study aimed to determine the prevalence of malnutrition among community-dwelling older adults using the GLIM criteria and to compare its diagnostic agreement with Mini Nutritional Assessment (MNA) and Geriatric Nutritional Risk index (GNRI). Materials and Methods:This cross-sectional study included 251 older adults aged 65 years or older from a university hospital's geriatric outpatient clinic.Nutritional status was assessed using GLIM, MNA, and GNRI.Anthropometric measures, body composition (as determined by bioelectrical impedance analysis), handgrip strength, and laboratory markers were evaluated.Cognitive and functional assessments were also conducted.Concordance among tools was analyzed using kappa statistics.Results: According to GLIM, 51.2% of participants were malnourished, compared to 42.4% with MNA and 7.1% with GNRI.GLIM identified malnutrition in 12.8% of patients with normal body mass index.Agreement between GLIM and MNA was moderate (p<0.001),while agreement between GLIM and GNRI was weak (p=0.001).Malnutrition was significantly associated with advanced age, female sex, cognitive impairment, and lower physical performance.GLIM showed greater sensitivity in identifying malnutrition and its clinical correlates.Conclusion: GLIM criteria are more sensitive in detecting malnutrition compared to MNA and GNRI, particularly in identifying individuals with subtle nutritional deficits.A multidimensional approach integrating GLIM with cognitive, functional, and body composition assessments is essential for early diagnosis and prevention in geriatric populations.
