Assessment of nutritional status in maintenance hemodialysis patients: A multicenter cross-sectional study in Iran.

Abstract

Protein-energy wasting (PEW) is common in hemodialysis patients and is linked with a high rate of morbidity and mortality. Regarding importance of nutrition in these patients, a recent study was administered to evaluate the nutritional status of hemodialysis patients. In this cross-sectional study 540 HD patients from 15 dialysis centers were evaluated. The nutritional status of the patients was determined by Subjective Global Assessment (SGA), Dialysis Malnutrition Score (DMS), and Malnutrition Inflammation Score (MIS). Their dietary intakes were assessed using a Food Frequency Questionnaire (FFQ). Based on DMS, 66.7% of HD patients were well nourished and the prevalence of mild-to-moderate and severe PEW were 32.4% and 0.9% in HD patients, respectively. Based on MIS, 65.2% of HD patients were well nourished and the prevalence of mild-to-moderate and severe PEW was 34.0%. The prevalence of mild-to-moderate and severe malnutrition based on SGA was 35.0% and 1.1%, respectively. Energy and protein intake in 85.6% and 80.6% of patients respectively were less than the minimum recommended amount. HD patients are at risk of malnutrition and in this regard training the patient, periodic assessment of nutritional status, and referring them to a dietitian seems necessary.
