Measurements by use of a conventional caliper process require skills and experiences. Further, since different pregnant women gain and keep fats in their bodies in different ways, results of measurements of their body fats vary. To overcome the inconvenience, there is provided a system for measuring a percent body fat or a total body fat by a bioelectrical impedance method, which comprises first input means, second input means and computation means, wherein personal data of a patient such as a height and a body weight is input into the first input means, a weight of a fetal part is input into the second input means, and the computation means computes a percent body fat or a total body fat by subtracting the body weight input into the second input means from the body weight input into the first input means.

A body weighing machine (100) is provided with a distance measuring sensor (30) at the central position (C) of a base plate unit (50). A CPU (10) measures the body weight of a human subject. The CPU (10) then drives the distance measuring sensor (30) to measure a distance (Dm) between the sensor and a floor surface and determines whether a minimum distance (D) between the base plate unit (50) and the floor surface is zero. The CPU (10) displays via a display unit (15) a message indicating that an error has occurred in a case in which the minimum distance (D) is zero, and otherwise displays the measured body weight on the display unit (15).

A sleep evaluation device (1) has a sensor unit (2) that constantly detects body movements of a human subject on bedding, and has a determiner that, based on results of detection, determines a sleep state and an aroused state of the human subject. The determiner quantifies results of detection of the sensor unit into N number of body movement data (where, N is a positive integral number satisfying N ≥ 2) and obtains, based on G number of standard deviations for each of G groups (in which G is an integral number satisfying 2 ≤ G N ) dividing N number of body movement data and for each body movement data and gs ( gs G ) number of standard deviations selected therefrom, L number of average value of standard deviations (where L is an integral number satisfying 2 ≤ L ≤ G ). The determination of a sleep state and an aroused state of the human subject is based on G number of standard deviations and L number of average values of standard deviations.
