APPLICATION OF BIOIMPEDANCE ANALYSIS FOR ESTIMATING BODY-COMPOSITION IN PREPUBERTAL CHILDREN INFECTED WITH HUMAN-IMMUNODEFICIENCY-VIRUS TYPE-1

The purpose of this study was to evaluate the performance of bioimpeda nce analysis (BIA) in the prediction of total body wafer and fat free mass with the use of standard equations in assessing 20 prepubertal ch ildren infected with human immunodeficiency virus (HIV). Total body wa ter was measured by means of deuterium oxide dilution, fat free mass b y means of total body dual X-ray absorptiometry, and BIA with a bioele ctrical impedance analyzer, The use of standard prediction equations r esulted in substantial error, Regression equations using height and BI A resistance for estimating total body wafer and fat free mass were de veloped and appear to improve accuracy for prediction, This study sugg ests that total body water and fat free mass can be estimated in child ren with HN by means of BIA equations specifically developed for use w ith this group of children.
