Özet

OBJECTIVES: Aging is characterized by appetite loss and cachexia, i.e., factors that contribute to malnutrition. An inflammation marker, neutrophil-to-lymphocyte ratio (NLR), is a significant prognostic predictor of many geriatric syndromes. We aim to determine the association between NLR and malnutrition. METHODS: We designed a retrospective study on hospitalized patients in the geriatric unit of a university hospital between January 2019 and January 2021. Demographic data, chronic diseases, history of smoking, length of hospital stay, number of drugs, laboratory and further examinations, and comprehensive geriatric assessment scores were recorded from the hospital data system. The nutritional status of the patients was evaluated using the mini-nutritional assessment (MNA) questionnaire.RESULTS: Of the 220 patients, 121 (55 %) were female, and the mean age was 77.9 & PLUSMN; 7.3 years. According to the MNA, 60 % (n = 132) were malnourished or at risk of malnutrition. As many as 47.3 % (n = 104) of the patients had depressive symptoms, and 41.4 % (n = 91) were cognitively impaired. The mean age (79.3 & PLUSMN; 7.3), NLR, and GDS scores were significantly higher, and MMSE scores were significantly lower in malnourished patients or in those at risk of malnutrition as compared to patients with normal nutritional status. We showed that NLR (OR: 1.248; 95% CI: 1.066-1.461; p = 0.006), age (OR: 1.056; 95% CI: 1.005-1.109; p = 0.031), depressive symptoms (OR: 1.225; 95% CI: 1.096-1.369; p < 0.001), and cognitive impairment (OR: 0.829; 95% CI: 0.739-0.931; p = 0.002) were independently associated with malnutrition. ROC curve showed that the optimum cut-off value to predict malnutrition risk was NLR > 4.5, with a sensitivity of 37.9 %, specificity of 85.2 %, negative predictive value of 47.8 %, and positive predictive value of 79.4 %.CONCLUSION: NLR, age, depressive symptoms, and cognitive impairment were independently associated risk factors for malnutrition. NLR may be a useful nutritional marker for evaluating the nutritional status of hospitalized geriatric patients (Tab. 4, Fig. 1, Ref. 28). Text in PDF www.elis.sk
