An abdomen width determiner determines an abdomen width of a subject. A shape index calculator calculates a shape index corresponding to a cross-sectional shape of an abdomen of the subject. An obesity evaluator evaluates whether an obesity degree of the subject is high or low. An obesity index calculator calculates an obesity index corresponding to the abdomen width using a first equation if the obesity evaluator evaluates that the obesity degree is low, and calculates an obesity index corresponding to the abdomen width and the shape index using a second equation different from the first equation if the obesity evaluator evaluates that the obesity degree is high.

An abdominal impedance measurement apparatus includes a plurality of electrodes for measuring an abdominal impedance of a human subject, and includes an electrode supporting member for supporting the electrodes in such a manner that the electrodes protrude from the electrode supporting member. The electrode supporting member includes a plurality of segments aligned in a direction, the electrodes being respectively mounted on different segments, neighboring segments being connected rotatably with each other. The electrode supporting member further includes rotation-angle restricting parts for restricting relative rotation-angles between neighboring segments.

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 &#x201c;a&#x201d; and &#x201c;b&#x201d; are constants.

In a load transfer mechanism which transfers load to a load cell that constitutes a Roberval mechanism, a load transfer member has at least an area right above a load cell mounting section in the top surface thereof as a concave surface area formed to be lower than the remaining area of the top surface thereof so that it does not contact a cover member. Thus, if the barycentric position of the load of an object to be weighed placed on the cover member, regardless of whether the load is concentrated load or divided load, the load transfer mechanism can reduce the difference of the influence of deflection of the load transfer member or moment imposed on the load, transfer given load to the load cell through the load transfer member and decrease a span error produced by the load position of an object to be weighed.
