うものが開示されている。2. Description of the Related Art Conventionally, body weight has been cited as a parameter of human health as a parameter. In recent years, however, body fat percentage has also been emphasized as one of the health factors. In response to this, various methods and devices for measuring body fat mass have been developed and proposed. For example, Japanese Patent Application Laid-Open No. Sho 62-169023 discloses a method of measuring body fat mass by inputting height, age, and gender, and measuring weight and impedance between body ends. Japanese Patent Publication No. 57-500900 discloses that an ultrasonic pulse wave is transmitted behind an animal to detect a wave (reception wave) reflected from a boundary between a fat layer and a muscle layer, and a time period from transmission to reception. The thickness of the fat layer is measured by measuring the thickness of the fat layer. Furthermore, Japanese Unexamined Patent Publication No.
In Japanese Patent No. 87139, subcutaneous fat is measured using ultrasound for each part of the human body, and a body fat estimated value for each part is calculated by multiplying by a cross-sectional area coefficient and a volume fat mass estimation coefficient of each part, and integrated. A method for estimating the amount of body fat is disclosed.

が既知なことから、脂肪の厚さが測定される。Next, in step 5, using the ultrasonic probe 20 or the skin hold caliper 20A,
The abdominal subcutaneous fat thickness is measured. In this case, the measurement of the abdominal subcutaneous fat thickness by the ultrasonic probe 20 is performed by A-mo.
Perform with de. The measurement data of abdominal subcutaneous fat thickness by the ultrasonic probe 20 or the skin hold caliper 20A is sent to a control circuit in the main body housing 10 or 10A. The measurement data by the skin hold caliper 20A may be read by the subject and input by the data input switch of the input unit 12A. Here, the A-mode subcutaneous fat thickness measurement will be described. A high-frequency ultrasonic wave is emitted from the ultrasonic probe 20 and the wave incident on the body surface is generated by the fat layer and the peritoneum or the fat layer and the muscle. The light is reflected at the interface with the layer and returns to the probe 20 again. Therefore, by measuring the time from the incidence to the return of the reflected wave, the thickness of fat is measured because the sound speed of fat is known.

b is obtained from the following equation using an actually measured value. b = {(XX [average]) · (YY [average])} / Σ
｛(XX [average] 2 ｝ a = Y [average] −b · X [average] The regression line illustrated in FIG. 8 is for a 25-year-old man,
It is known that such a regression line slightly differs depending on personal parameters such as gender, age, and height. Therefore, by performing correction based on such personal parameters, more accurate estimation of fat area can be performed. A. (2) Calculation of abdominal subcutaneous fat (cut) area The abdominal subcutaneous fat area is determined from the correlation between abdominal sebum thickness or abdominal sebum thickness × waist (see FIG. 10).

ができる。Abdominal radius = waist / (2π) Subcutaneous fat area = abdominal radius 2 × π− (abdominal radius−abdominal sebum thickness) 2 × π Further, the abdominal sebum thickness is sufficiently larger than the abdominal circumference (waist). Because of its small size, the subcutaneous fat area can be expressed as:

肥満とされている。Then, since the actual human body is not a perfect circle, there is a gap between the actually measured value and the estimated value, but there is a regression indicating the correlation between the above estimated value of the subcutaneous fat area and the actually measured value. The line is almost a straight line, and it is possible to estimate the abdominal subcutaneous fat area by measuring the waist and the sebum thickness. A. (3) Calculation of abdominal visceral fat area The abdominal visceral fat area is determined by subtracting the abdominal subcutaneous fat area from the abdominal total fat area. A. (4) Calculation of abdominal visceral fat area / abdominal subcutaneous fat area (1) Calculation of abdominal visceral fat area The abdominal visceral fat area is determined from the correlation with the waist (FIG. 9).
reference). B. (2) Calculation of Abdominal Subcutaneous Fat Area The abdominal subcutaneous fat area is determined from the correlation with the sebum thickness or waist × abdominal sebum thickness (see FIG. 10). B. (3) Calculation of abdominal visceral fat area / abdominal subcutaneous fat area Next, the criteria for determining visceral fat will be described.
It is said that visceral fat obesity is more influential than subcutaneous fat obesity as an influencing factor for lifestyle-related diseases such as diabetes. Therefore, as a boundary between the two, a subcutaneous fat area and a visceral fat area are obtained from a cross-sectional image of the navel portion by CT scan or MRI, and if visceral fat area / subcutaneous fat area is 0.4 or more, visceral fat obesity, 0 If it is less than 0.4, it is regarded as subcutaneous fat type obesity.
