The relationship between nutrition screenings and nutritional status determined by malnutrition in hemodialysis patients

Abstract

Objective: It is aimed to evaluate the relationship of food consumptions, biochemical blood parameters, and some anthropometrics with the screening tests using in the nutritional status of hemodialysis patients with end stage renal failure.

Materials and Methods: The survey were conducted with 110 hemodialysis patients who hospitalized at the Nephrology Clinic in Akdeniz University Hospital. The routine biochemical blood parameters of the patients were analyzed and their anthropometric measurements were performed. The food consumptions were recorded by the dietician and Nutritional Risk Screening 2002 (NRS 2002), Malnutrition Universal Screening Tool (MUST) and Subjective Global Assessment (SGA)has screening tests using were performed.

Results: The average age of the patients participating in the study was 55 ± 19 years. In MUST, 42.7% of the patients were at high risk, 18.2% of them at moderate risk by malnutrition. Statistically significant relationship was also negatively determined between body weight, dry weight, BMI, the waist circumference, and MUST and SGA (p<0.05). A negatively significant relationship was statistically found among albumin, creatinine, hemoglobin and calcium readouts by NRS2002, among albumin, BUN, calcium and phosphorus readouts by MUST, among albumin, hemoglobin and calcium readouts by SGA (p<0.05).

Conclusion: It was observed that the dialysis patients could not get the advised nutritional quantities, thence malnutrition progressed. It is concluded that anthropometric measurements are more concordant with MUST and the biochemical symptoms with NRS2002, and therefore both must be taken into consideration in the assessment of nutritional status correctly of the end-stage renal patients undergoing hemodialysis.
