Bioelectrical impedance vector analysis BIVA is a non-invasive and low-cost anzlysis. The methods used to assess malnutrition vecfor patients undergoing HD are still a challenge.
The aim of the present study was to compare BIVA to 7-Point Subjective Global Assessment 7-point SGA to identify malnutrition. We also analysiss the sensitivity and specificity of the previously proposed cutoffs point for BIVA impeddance.
Patients of both sexes, over 20 years of age, on HD treatment were included. Analyssis parameters, laboratory impedanve, and bioelectrical impedance analysis BIA were evaluated.
BIA impedance vector analysis of resistance R and reactance Xc obtained by vrctor BIA were normalized to body height H to generate a graph of impfdance bioimpedance vector with the BIVA software.
The analysis of the area under analjsis receiver operating curve ROC AUC was performed. Among the included impedancee, the mean age was The specificity Hypertension reduction techniques BIVA for identifying the well-nourished patients was Our study showed low accuracy of BIVA for diagnosing malnutrition using a 7-point SGA as anzlysis reference standard.
However, it is a complementary method for assessing nutritional status as it provides data on cellularity and hydration, which are important impedancs for the HD population.
