 note = {The aim of this study was to determine accuracy of indices of body composition by bioelectrical impedance analysis (BIA). Measurements were performed in 60 normal Japanese volunteers (41 male, 19 female) and in 11 patients with chronic renal failure (7 male, 4 female), aged 25～85 yrs, Resistance was obtained by BIA using a tetrapolar electrode of 500μA and 50kHz current. Weight (Wt), height (Ht), arm circumference and triceps skinfold thickness (TSF) were measured in healthy subjects and twice measured in patients once before and once after dialysis. Lean body mass (LBM) and percentage fat (%BF) were expressed as Ht^2/R and RWt/Ht^2, respectively. Percent ideal body weight (%IBW), body mass index (BMI), body surface area (BSA), weight (BW)^<0.75>, arm muscle circumference (AMC) and arm muscle area (AMA) were calculated from the criterion methods. In healthy subjects, significant correlations were obtained between Ht^2/R and BSA, BW^<0.75>, AMC and AMA, respectively (p<0.01, p<0.01, p<0.01, p<0.01). Significant correlations were found between RW/Ht^2 and %IBW (p<0.05), BMI(p<0.01), and TSF (p<0.01), respectively. There were significant differences in R, Ht^2/R and RW/Ht^2 before and after dialysis (p<0.01, p<0.01, p<0.01). Significant positive correlations were seen between changes in Ht^2/R and both decreases in water (ml) and changes in weight following hemodialysis (p<0.01, p<0.01). The results suggest that the BIA is as reliable a method in determining LBM as anthropometric methods in a healthy Japanese population. The results also suggest that R is sensitive in detecting alternation in TBW. Changes in Ht^2/R are also useful in estimating changes in TBW associated with dialysis.},
