Problems solved by technology

In these measurements, no difference was seen in the electrophysiological properties between visceral fat and subcutaneous fat, so it was planned to measure only visceral fat by the mutual positional relationship of specific configured electrode pairs, but the problem is that the amount of subcutaneous fat affects the impedance value, the result is to affect the measurement accuracy

Embodiment Construction

[0039] Next, embodiments and examples of the present invention will be described.

[0040] FIG. 1 is a block diagram showing a schematic configuration of a visceral fat calculation device 1 according to an embodiment of the present invention.

[0041] The visceral fat calculation device 1 includes a control / calculation unit 2 , a measurement current generator 3 , electrode switching circuits 4A and 4B, electrode groups 41 to 48 , a voltage measurement unit 5 , an input unit 6 , a display unit 7 , and an output unit 8 .

[0042] The control / calculation unit 2 sends control signals to the measurement current generation unit 3 , the input unit 6 , the display unit 7 , and the output unit 8 to control the measurement operation of the visceral fat calculation device. In addition, the control / calculation unit receives the input of the subject information from the input unit 6, and stores it in a not-shown RAM (memory unit for the subject information). In addition, the information s...

Abstract

A visceral fat area of a subject is calculated based on an equation using as variables a sex of the subject, and an electric impedance ratio between the longitudinal width of the abdomen and the transversal width of the abdomen of the subject. As an example of the equation, let the visceral fat area (cm2) be VFA and the longitudinal-transversal impedance ratio of the abdomen be R1, then VFA=a1+b1xR1 (where a1 and b1 are constants). A visceral fat area of the subject is also calculated based on an equation using abdomen circumference as an additional variable. As an example of the equation, let the abdomen circumference (cm) be W and the longitudinal-transversal impedance ratio of the abdomen be R4, then VFA=Wx(a4+b4xR4)+c4 (where a4, b4 and c4 are constants) or VFA=W2x(alpha4+beta4xR4)+gamma4 (where alpha4, beta4 and gamma4 are constants). The calculated visceral fat area is compared with the reference value, and the comparison results are outputted. In the same manner, visceral fat weight and visceral fat volume can be calculated.

Description

technical field [0001] The present invention relates to a visceral fat calculation method and its device with the function of calculating the area of ​​visceral fat at the high position of the abdominal umbilical cord according to the biological impedance. Background technique [0002] In recent years, the increase in the obese population has also pointed out the importance of health management, and the degree of concern for obesity has also increased. Among them, it is known that visceral fat is closely related to the incidence risk of lifestyle-related diseases seen clinically, and interest in simple and accurate measurement of visceral fat is rapidly increasing. [0003] Regarding the simple visceral fat calculation method and its device in the past, the most used is the bioimpedance method, such as in JP-P11-123182, JP-2000-175875, JP-2001-286452, JP-2002 - Publication No. 315730 discloses a technique for measuring impedance by arbitrarily arranging a plurality of elect...
