Aim: The purpose of this study was to test validity of bioelectrical impedance (BIA) analysis in the nutritional assessment among patients with receiving hemodialysis. Method: This study which was cross-sectional was conducted with 166 patients with hemodialysis at the hemodialysis units in two state hospital and a private hospital. The data were collected by means of patient information form, Malnutrition Inflammation Score (MIS) and Body Composition Analyzer. Descriptive, t test, Mann-Whitney U, chi-square, Wilcoxon, ROC analysis and logistic regresyon analysis were used in statistical analysis. Results: The average ages of patients were 51.57±13.01 (21-66) years. Of the patients, 53.6% were male. Mean body mass index (BMI) was 24.4±4.98 kg/m2 of whom (%54.8) were well-nourished. Male patients had higher albumin, muscule mass, and BMI than female patients and these values were statistical difference in according to gender. A significant difference was found to hemoglobin, albümin, iron binding, tanita fat ratio, fat mass, and BMI between the well-nourished and malnourished patients. The findings of logistic regretion analysis among MIS and BIA parameters shown that performance of BIA was statistical significantly. Conclusion: The results of study indicated that bioelectrical impedance analysis was shown to identify the most suitable BIA parameters for predicting presence of malnutrition. It could be suggested that BIA method may use for assess to nutritional status among patients receiving hemodialysis.
