摘要:
A CPU (134) of a body composition measuring apparatus (100) drives a navel position indicator (118) so that it emits light. The height of a frame (114) is adjusted so that a beam of light from navel position indicator (118) irradiates the navel of a human subject. Plural sensors (106) are mounted on the frame (114), and each sensor measures a distance from the sensor to a position to be measured, whereby the abdominal width (X) of the human subject is determined. Subsequently, CPU (134) obtains measured values of weight (W) and bioelectrical impedance (Z). CPU (134) then reads an equation for calculating the visceral fat area and estimates the visceral fat area (Y) based on the measured abdominal width (X), weight (W), bioelectrical impedance (Z), and the equation.

摘要:
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.

A CPU (170) of a human subject index estimation apparatus (1) computes a waist circumference based on body weight measured by a weight scale (110) and bioelectric impedance measured by a bioelectric impedance measurement unit (200A), and information such as age and height which was input through input unit (150). The computed waist circumference is stored, along with the information such as age and height, in a third storage unit (140) that is a rewritable non-volatile memory. The CPU (170) displays the waist circumference on display unit (160).
摘要:
An abdomen width determiner determines an abdomen width value of a human subject. A memory stores a correlation between abdomen width values and waist circumferences of human beings. A waist circumference calculator calculates a waist circumference of the human subject on the basis of the abdomen width value determined by the abdomen width determiner and the correlation stored in the memory. The correlation stored in the memory may be expressed by the following regression formula: Y=aX+b where “Y” is a waist circumference of a human being, “X” is an abdomen width value of a human being, and “a” and “b” are constants.
