Prevalence of malnutrition diagnosed by the GLIM and MNA in older adult outpatients and comparison between the GLIM and MNA energy-protein intake: a cross sectional study.

BACKGROUND The Global Leadership Initiative on Malnutrition (GLIM) published malnutrition identification criteria. The Mini Nutritional Assessment (MNA) is a malnutrition assessment tool commonly used in older adults. The aims of this study were to determine prevalence of malnutrition and the relationship between the GLIM and the MNA long form (MNA-LF) and short form (MNA-SF), and energy-protein intake. MATERIALS & METHODS A total of 252 older adult outpatients (aged 68.0 years, 61% females) were included. Malnutrition was defined according to the GLIM, MNA-LF, and MNA-SF. Food intake was assessed using the 24-hour Dietary Recall. We analyzed the cut-off value on the MNA-LF score, MNA-SF score, and energy-protein intake for GLIM criteria-defined malnutrition severity with receiver operating characteristic (ROC) analysis. RESULTS Malnutrition was present in 32.2%, 12.7%, and 13.1% of patients according to the GLIM criteria, MNA-LF, and MNA-SF, respectively. It was determined that 92.7% and 89.0% of patients based on GLIM criteria had malnutrition with the MNA-LF and MNA-SF, respectively. The daily energy-protein intake was less in patients with malnutrition according to GLIM, as in the MNA-LF and MNA-SF classifications (p < 0.05). For the MNA-LF and MNA-SF score, the cut-off value of 11 and 9 points for severe malnutrition [area under curve (AUC) 0.92, p < 0.001; 0.90, p<0.001], and 22 and 11 points for moderate malnutrition [AUC 0.79, p<0.001; 0.76, p<0.001] were determined. CONCLUSION According to the GLIM criteria, one third of outpatient older adults were malnourished, whereas the prevalence was much lower applying both the MNA-LF and the MNA-SF.
