The author surveyed, besides serum cholesterol level as means of epidemiological study of cardiovascular diseases, distribution of fat deposits (skin-fold thickness) in the body as an index of nutritional state, and compared, between urban and rural rcg ions, changes by age and sex in the latter. Out of the fat deposits at 31 sites of the body of essential hypertensive patients, which were given in Chef irst report, 13 pairs of the right and left symmetrical positions do not show any significant difference between each pair (0.3mm, p>0.05). In search for definitive tendency, fat deposits in total 18 sites 13 on the right side and 5 on the median line were reexamined. 1) In general, fat deposit is thicker in the middle and lower gluteal regions, in upper 1/3 between the navel and pubis, and in the middle between the xiphoid and navel. 2) Fat deposits show nearly the same distribution in both sexes either in Tokyo or in Hirai. Males of 4049 years have most approximate patterns in both regions, but the mean valves are generally higher in Tokyo. Conversely females give higher means in Hirai, especially in abdominal fat deposit ; with regard to the distribution pattern, relative thoracic fat deposit is greater in females of Tokyo. 3) Change by age in Fat deposit was examined in both sexes and both regions with the value in 40-49 years taken as the standard. a) In males In Tokyo, fat deposits in the lumbar region are thin in each age group. In the other regions fat deposits are varying in different age groups. In 5059 years, fat deposit is thin at sites, in 6069 years at 2 sites, and 7079 years at 6 sites. In Hirai, fat deposits are thin in all the abdominal regions except the lumbar in two age groups of 50-59 and 60-69 years in contrast with the results of the Tokyo group. Fat deposit is thin at 11 sites in 50-59 years, at 8 sites in 60-69 years, and at 5 sites in 70-79 years. b) In female In the Tokyo group, fat deposits in 50-59 and 60-69 years are not significantly different from the standard almost in any region. In 70-79 years, fat deposits are decreased in the Upper 1/3 of the tensor side of the upper arm, on the back, breast and gluteal region. The Hirai group showed a similar tendency to the Tokyo group in 50-59 and 60-69 years. In 60-69 years, however, similar, significant decrease is seen in gluteal region, and in 70-79 years fat deposits are low in all the regions except the middle between the navel and rib. Thus it can be said that fat deposit begins to decrease in the gluteal region in 60-69 years, and becoms abruptly smaller in 70-79 years.
