PROBLEM TO BE SOLVED: To obtain accurate body composition information on the abdomen by using the shape of the abdomen.SOLUTION: The body composition measuring device includes: a width obtaining part 11A for obtaining the vertical width and lateral width of the abdomen of a subject in a supine position a deformation degree obtaining part 122 for obtaining the degree of deformation of the shape of the abdomen of the subject lying in a supine position from an oval shape defined by the obtained vertical width and lateral width of the abdomen and an information obtaining part 124 for obtaining body composition information of the abdomen of the subject. The information obtaining part obtains the body composition information of the abdomen of the subject by using biological impedances of the abdomen of the subject and a coefficient based on the obtained degree of deformation.COPYRIGHT: (C)2013,JPO&INPIT【課題】腹部形状を用いて精度よく腹部の体組成情報を取得する。【解決手段】被測定者の仰臥位における腹部の縦幅と横幅とを取得するための幅取得部11Aと、取得される腹部の縦幅と横幅とで規定される楕円形状からの、被測定者の仰臥位における腹部形状の変形度を取得するための変形度取得部122と、被測定者の腹部の体組成情報を取得するための情報取得部124と、を備える。情報取得部は、被測定者の腹部の生体インピーダンスと、取得された変形度に従う係数とを用いて、被測定者の腹部の体組成情報を取得する。【選択図】図3
