A body index apparatus (100) has a measurer for measuring, at plural measurement points, the distance indicating the width of abdomen (11) of a human subject (10) who lies on a reference plane (S) in the supine position. The distances from these measurement points to the reference plane (S) are different from one another. The measurement points are included in a plane (G) intersecting the reference plane (S) and are positioned so that the maximum width of the abdomen (11) in the plane (G) is between a measurement point that is the closest to the reference plane (S) and a measurement point that is the most distant from the reference plane (S). The body index apparatus (100) estimates an obesity index by calculation using the value of the ratio of the first distance to the second distance that is a distance at a predetermined measurement point, the first distance indicating the maximum width of plural distances measured at the plural measurement points. |
