同一被験者の体組成を生体インピーダンス法（BIA法）と二重エネルギーX線吸収法（DXA法）で測定し，四肢，体幹部および全身について体脂肪率，体脂肪量，推定筋肉量，重量を求めた。全身の体脂肪率，体脂肪量，重量（体重）の平均値は比較的近い値が得られた。二つの測定法の測定値は有意な相関があったが，四肢に比べて体幹部，全身で高い相関が認められた。体幹部や全身のように測定対象範囲が広い場合にはBIA法は体組成測定に有用な方法であることがわかった。

We measured body component indexes of the same participants using bioelectrical impedance analysis (BIA) and dual energy X-ray absorptiometry (DXA). Body fat percentage, fat mass, lean mass and weight were obtained for upper and lower extremities, trunk and whole body. Mean values of body fat percentage, fat mass and weight for whole body obtained by using two methods were in comparatively close agreement. Measured values of BIA and DXA correlated significantly for all regions. Values of the correlation coefficient for trunk and whole body were higher than those of extremities. BIA is a useful method for broad regions such as trunk or whole body.
