A study was conducted to assess gender differences of body fat distribution(i.e., total body fat mass, subcutaneous fat mass, and internal fat mass)in a homogeneous group of Japanese children.Body composition was estimated in 141 boys and 139 girls(aged 3縲鰀6 yr)using bioelectrical impedance analysis(BIA).All subjects were apparently healthy.Determinations of impedance were made using a four-terminal impedance analyzer(TR-95 K, Toyo Physical, Inc., Fukuoka).The lean body mass(LBM)was calculated using the equation of Kushuner et al.(1992)and Goran et al.(1993).Total body fat mass(TFM)was calcu...
