Abstract
The thickness of the hypodermic fatty layer was measured on 183 subjects of junior high school boys and girls in Tokyo. The measurement was taken from 36 different points of the body and the interrelationship between the thickness and the body type was examined. Body type was divided into 4 groups ; thin, standard, fatty and very fatty.
1. The thickness of the hypodermic adipose tissue was thicker in order of body types from very fatty to thin, but was seen few difference between the thin type and the standard type on boys.
2. The increasing rate of the thickness of hypodermic fatty layer in 4 body types was remarkable on the circumference of navel by standard type, on the anterior part of trunk, proximal anterior part of upper extremity and upper posterior part of trunk by fatty type, and on the breast, anterior part of trunk and proximal part of upper extremity by very fatty type respectively on boys. On the other hand, it of girl was remarkable on the thinner part of hypodermic fatty layer in body and was remarkable around the hip by very fatty type.
3. The distribution of the subcutaneous adipose tissue on the very fatty type was remarkable on the upper half of body by boy and on the lower half of body by girl respectively.
4. Concerning the hypodermic adipose tissue of junior high school boys and girls in Tokyo, it can be said that the distribution pattern, sex-difference and age-related changes are resemble to them in other district of Japan but the thickness is larger than its in Okinawa.
5. From the thickness of the hypodermic fatty layer, thin type was equivalent to those of below 119 of Rohrer's index on both sexes, standard type to 120-139 on boys and to 120-129 on girls, fatty type to 140-149 on boys and to 130-149 on girls, and very fatty type to more than 150 on both sexes.
