Abstract

A body composition management apparatus for a pregnant woman which measures body fat or body water by a bioelectrical impedance method is provided. The apparatus comprises: first input means, second input means, measurement means, first computation means, and second computation means, wherein the first input means inputs personal data of a pregnant woman such as a body height and a body weight, the second input means inputs the gestational weeks, the measurement means measures the bioelectrical impedance of the pregnant woman, the first computation means computes a body fat mass or a total body water from the personal data and the impedance, and the second computation means computes a body fat mass or total body water in a non-pregnant state from the computed body fat mass or total body water and the amount of an increase in body weight from the non-pregnant state.

Claims

1. A body composition management apparatus for a pregnant woman which measures body fat or body water by a bioelectrical impedance method, the apparatus comprising:

first input means,

second input means,

measurement means,

first computation means, and

second computation means,

wherein

the first input means inputs personal data of a pregnant woman such as a body height and a body weight,

the second input means inputs the gestational weeks,

the measurement means measures the bioelectrical impedance of the pregnant woman,

the first computation means computes a body fat mass or a total body water from the personal data and the bioelectrical impedance, and

the second computation means computes a body fat mass or total body water in a non-pregnant state from the computed body fat mass or total body water and the amount of an increase in body weight from the non-pregnant state.

2. The apparatus of claim 1, wherein the second input means takes in an expected date of birth so as to determine the gestational weeks.

3. The apparatus of claim 1, which prepares health management data from a change in the body fat mass or total body water between the non-pregnant state and the time of the measurement.
