Orlando—Patients with end-stage renal disease (ESRD) are at risk for impaired nutritional status. Ragda Barakat and colleagues in Israel recently conducted a cross-sectional study designed to evaluate dietary intake and quality, nutritional status, and indicators of ESRD in a cohort of patients on maintenance hemodialysis. The researchers reported study results during a poster session at the NFK Spring Clinical Meetings in a poster titled Nutritional Status, Dietary Intake and Quality among Chronic Hemodialysis Patients.
The study cohort included 74 patients on chronic hemodialysis. Twenty-four-hour dietary recalls were collected for 3 days: the day prior to, the day of dialysis, and the day following dialysis. The protein catabolic rate and the Subjective Global Assessment (SGA) were gathered.
Mean caloric intake was 1683.9 calories per day, a nearly 20% deviation from guideline recommendations for hemodialysis patients. Among macronutrients, carbohydrates were the major deviation from the guidelines. Study participants consumed 25% less carbohydrates than the recommended intake for patients on hemodialysis.
Mean energy intake was highest on the day of the dialysis session (1766 calories/day), and lowest on the day after dialysis (1651.5 calories/day). There was a correlation between the protein catabolic rate and urea values (P=.004), the urea reduction ratio (P=.019), and the KT/v (P=.023). There was no correlation between the protein catabolic rate and diet and nutritional status. SGA calculations demonstrated that 71% of patients were well nourished, 23.4% were borderline nourished, and only 1.4% were undernourished.
“We showed differences in the dietary intake of hemodialysis patients between the days of the week that warrant further studies. Based on our findings, future intervention studies may focus on the day after dialysis,” the researchers said.
