Association of nutritional status and diet quality in hemodialysis patients

Abstract

Variety and adequacy of food intake as well as dietary pattern affect nutritional status of hemodialysis (HD) patient's. The aim of this study was to investigate the quality of diet and nutritional status in HD patients and to find out the relationships among the variables. We assessed nutritional status and diet quality of 63 HD patients (age: 55.3 ± 11.9 yrs; men/women ratio: 49.2%/50.8%) using Subjective Global Assessment (SGA) and 3‐day diet recall methods, respectively. Patient's daily energy intake (DEI) and protein intake (DPI) were 21.9 ± 6.7 kcal/BW/day and 0.9 ± 0.3 g/BW/day, respectively. About 70% of HD patients appeared to have lower daily energy and protein intake compared to recommended amount. More than 50% of HD patients had lower intake of vitamin C, B1, B2, niacin, folate, calcium, and zinc below75% of Dietary recommended intakes. Nutrient intakes per 1,000kcal indicated that HD patients had diets that were lower in nutrient density for Vitamin C, B1, B2, folate, and calcium. There was significant positive correlation between DEI and SGA scores (r=0.3, p<0.05). DQI‐I was significantly correlated with DEI, DPI and lean body mass (kg) (r=0.5, p<0.01; r=0.4, p<0.01; r=0.3, p<0.05, respectively). As increased in disease severity measured by End‐Stage Renal Disease Severity Index (ESRD‐SI), FVS score decreased (r=−0.3, p<0.05). The results of this study indicate that HD patients in Korea consumed less calories, protein, vitamin C, B1, B2, folate, and calcium than recommended amount for each nutrient for HD patients. This study also confirmed that nutritional status and disease severity were significantly correlated with dietary quality.Grant Funding Source: ASN
