The purpose of this study was to examine the estimate precision for body composition calculation for fat free mass (FFM) using underwater weighing (UWW), deuterium dilution technique (DDT), and dual energy X-ray absorptiometry (DXA) in Japanese children. The subjects of this study were 21 healthy Japanese children (boys: n=8; girls: n=13) from 6 to 15 years old. There were no significant differences among each mean values of FFM estimated by UWW, DDT and DXA. Significant correlation was found in both boys and girls between UWW and DDT (boys: r=0.997, girls: r=0.989), between DDT and DXA (boys: r=0.988, girls: r=0.985) and between UWW and DXA (boys: r=0.996, girls: r=0.977). We conclude that UWW, DDT and DXA have close correlations in the estimation of FFM for Japanese children.
