As the incidence of chronic diseases such as diabetes and hypertension increases, complications such as decreased renal function are also increasing in many patients. Nutritional management in hemodialysis patients is a very important factor for prognosis and quality of life. The purpose of this study was to investigate the differences in nutritional status and dietary management according to hemodialysis duration. A total of 145 patients were divided into 4 groups according to hemodialysis duration: less 1 year (D1), 1–5 years (D2), and above 5 years (D3). The rates of protein-energy wasting were 31.1% in D1 group, 49.5% in D2 group, and 47.6% in D3 group. However, there was no significant difference between the 3 groups. Nutrient intake analysis showed that protein, iron, and vitamin C were significantly lower in the D3 group than in the D1 group. Protein intake in all 3 groups was insufficient compared to the recommended dietary amount for dialysis patients. The most difficult aspect in dietary management was cooking with low sodium. In the D3 group, which had the longest duration of dialysis, the practice of diet therapy and self-perceived need for nutrition education was lowest. Observations of nutritional status are necessary to maintain the health status of dialysis patients. In addition, education plans should be prepared to mediate the nutrient intakes and identify the patient's difficulties and provide practical help.

This study set out to evaluate the impact of personalized nutritional counseling (PNC) on the nutritional status of hemodialysis (HD) patients. This was an intervention study for 10 months at 2 hospitals. Anthropometric, biochemical, dietary, and body composition parameters were measured at baseline and after 3 and 6 months of PNC. A total of 42 patients (23 men and 19 women) were included. Intake of dietary protein, serum albumin, and cholesterol levels had increased significantly from baseline to month 6 (p < 0.05). Among the bioelectrical impedance analysis (BIA) parameters, both the body cell mass (BCM) and the fat free mass (FFM) had significantly reduced at month 3 compared to baseline (p < 0.05). However, there was no difference between baseline and month 6. We assessed the nutritional status of the subjects using the malnutrition inflammation score (MIS), and divided them into an adequately nourished (AN) and a malnourished (MN) group at baseline. In the subgroup analysis, serum levels of albumin and cholesterol had increased significantly, particularly from baseline to month 6 in the MN group (p < 0.05). This study suggests that consecutive PNC contributed to the improvement of the protein intake, serum levels of albumin, cholesterol and to the delay of muscle wasting, which could also have a positive impact on the nutritional status, particularly in malnourished patients receiving HD treatment.

Poor diet quality is one of strong predictors of subsequent increased mortality in hemodialysis patients. To determine diet quality and to define major problems contributing to poor diet quality in hemodialysis patients, a cross-sectional study was conducted between June 2009 and October 2010. Sixty-three hemodialysis patients (31 men, 32 women; aged 55.3 ± 11.9 years) in stable condition were recruited from the Artificial Kidney Center in Kyung Hee University, Seoul, Korea. Three-day diet records were obtained for dietary assessment. Mean adequacy ratio (MAR) is the average of the ratio of intakes to Dietary Reference Intakes (DRI) for 12 nutrients. Index of nutritional quality (INQ) was determined as the nutritional density per 1,000 kcal of calories. Overall diet quality was evaluated using the Diet Quality Index-International (DQI-I). Statistics were used to determine diet quality, comparing dietary intake to DRI. Dietary calories (21.9 ± 6.7 kcal/kg/day) and protein (0.9 ± 0.3 g/kg/day) were found insufficient in the participants. The overall intake of 12 nutrients appeared to be also inadequate (0.66 ± 0.15), but INQs of overall nutrients, except for folate (0.6) and calcium (0.8), were found relatively adequate (INQ ≥ 1). As a result of diet quality assessment using DQI-I, dietary imbalance and inadequacy were found to be the most problematic in hemodialysis patients. This study suggests that the main reason for insufficient intake of essential nutrients is insufficient calorie intake. Hemodialysis patients should be encouraged to use various food sources to meet their energy requirements as well as satisfy overall balance and nutrient adequacy.
