Background and Objective: Protein-energy malnutrition (PEM) is one of the most prevalent problem in renal patients that can decrease quality of life and increase mortality in these patients. The aim of this study was to compere three different methods of nutritional assessment for evaluation the nutritional status of these patients.
Subjects and Methods: In this study, 30 pediatric patients with chronic kidney disease (6 to 20 years) with GFR=15-60 ml/min/1.72m2 were selected and compared with 30 healthy control subjects. Nutritional assessment was made by use of subjective global assessment (SGA), measuring serum albumin, pre-albumin, IGF-I and body composition analysis performed by bioelectric impedance analysis (BIA) method. The data were analyzed using SPSS software, normally distributed variables were expressed as mean ± Standard Deviation (SD) and were compared by Independent Student’s t-test. means were considered significantly different at P<0.05.
Results: Based on SGA score none of CKD patients had severe malnutrition. Mean albumin and IGF-1 level, were significantly lower in CKD children. BIA results showed patients with CKD had significantly lower dry lean weight, body cell mass, body mass index and basal metabolic rate.
Conclusion: The result of present study showed BIA compared with SGA and biochemical factors is more effective in early detection of malnutrition in CKD children. Therefore this study suggests that BIA can be an attractive clinical tool to detect malnutrition in CKD.
