[Fat distribution in Japanese women. Part 2. Fat thickness of extremities and classification of fat distribution of whole body].
The first object of this paper was to follow the previous paper in clarifying the characteristics of the fat distribution on the extremities. The subcutaneous fat thickness was measured at 64 points on the upper extremity and on 129 points on the lower extremity. The difference of the fat distribution between obese subjects and lean subjects was mainly observed on the back of the upper arm and the thigh. The second object of this paper was to clarify the characteristics of the fat distribution on both the trunk and the extremities and to study the factors which contribute to the fat distribution of the whole body. Average subcutaneous fat thickness over the body was 7.8 mm, and the standard deviation was 1.2 mm. Types of fat distribution of the whole body were classified by principal component analysis of average fat thickness in the 8 regions. The first component was the size factor which expressed the amount of fat on the whole body. The second component showed the contrast of fat distribution in the lower extremities and in the breast, abdomen, back and arms. These two components accounted for 90.79% of the variance of fat distribution. Measuring points, which showed high correlation coefficient with the average fat thickness of the whole body, were abdomen, subscapular, back, thigh and side breast.
