The association between MNA and PG-SGA malnutrition assessment and the quality of life among hemodialysis patients

Abstract

BackgroundThe simple nutritional assessment tools by Mini Nutritional Assessment (MNA) and Patient Generated Subjective Global Assessment (PG – SGA) was proposed to affect the Quality of Life (QOL) in hemodialysis patients. However, currently, no evidence assessed the potency of MNA and PG - SGA for predicting the QOL in hemodialysis patients. ObjectiveTo assess the potential implication of MNA and PG-SGA nutritional tools and the QOL among hemodialysis patients. MethodsA cross - sectional study was performed in Universitas Muhammadiyah Malang Hospital, Malang, Indonesia. A validated Kidney Disease Quality of Life – 36™ (KDQOL – 36™) instrument was used to assess the QOL. The nutritional status was assessed using MNA and PG - SGA checklist. The association between nutritional status and QOL was determined by using multiple logistic regression. ResultsA total of 96 hemodialysis patients was enrolled in our study. Of them, good QOL was observed in 75 patients (78.12%). We found that hemodialysis patients with higher MNA score and lower PG - SGA score was associated with good QOL. We also found that normal MNA nutritional status was associated with good QOL. Moreover, we also found that the score of MNA ≥23.75 and PG - SGA score ≤3,5 were associated with good QOL. ConclusionMNA and PG-SGA nutritional assessment tools are the important indicator in predicting the QOL in hemodialysis patients.
