Abstract :
Introduction: Malnutrition is one of the most common causes of mortality and morbidity in dialysis patients. This study aimed to evaluate the correlation between nutritional indices and hemodialysis adequacy. Material & Methods: This descriptive cross-sectional study was performed on 257 patients undergoing chronic hemodialysis in 6 dialysis centers in Zanjan province, Iran. Patients were selected by convenience sampling. Blood samples were examined in a single laboratory. Anthropometric indices included BMI, TSF, MAC and MAMC. Data were analyzed using descriptive statistics, t-test, and Spearman correlation coeffi cient with SPSS software version 22. Results: The nutritional indices in hemodialysis patients were in an acceptable range. The mean BMI of patients was 23.38±4.11 kg/m2. The mean serum albumin index was 4.18±0.91 g/dl. Serum total protein index was 7.2±1.11 mg/dL. In 90.3 of patients the creatinine (Cr) was 12 mg/dL. The arm circumference (MAC) index was between 60-90 percent of normal. Mid-arm muscle circumference (MAMC) in 50 of the patients was between 60-90 of normal. The skinfold thickness of the triceps (TSF) was 9.33±4.52 mm. BMI had negative correlation with kt/v (r=-0.17, P=0.005) and URR (r=-0.15, P=0.01). There was a positive correlation between protein index and URR (r=0.14, P=0.02). Conclusion: Some nutritional indices in hemodialysis patients are related to dialysis adequacy. This fi nding shows the need for careful monitoring of patients nutritional status between dialysis sessions. The fi ndings of the study on the nutritional status and adequacy of dialysis indicate the proper planning of dialysis centers with skilled professionals and the existence of up-to-date technology.
