The purpose of the present report was to reveal the physical characteristics and to discuss the relation between body fat and medical parameters. Measurements of height, weight and skinfold thickness were carried out on 1004 adults (481 males and 523 females), living in Yonaguni island. Body fat (%Fat) was estimated from skinfold thickness according to the Nagamine's method. Mean height of Yonaguni islanders was similar to the other Japanese. groups, but that or younger islanders were lower than both that of' urbanites in Fukuoka and that of Japanese. These results imply that the socil-economical levels of Yonaguni island has not reached the average level of Japan. Mean body weight was heavier than that of the other Japanese groups. However, mean skinfold thickness and %Fat were smaller than those or the other Japanese groups. 25.8 % of the male and 27.5 % of the female belonged to obesity by the modified Broca's method but to normal %Fat by the skinfold method, although only 1.1 % of the male and 3.9 % of the female belonged to obesity by the skinfold method but normal weight by the modified Broca's method. These results suggest that the heavier body weight of Yonaguni islanders depends on the increase of lean body mass but not of fatty mass. The correlation between %Fat and medical parameters was as follows ; %Fat showed the significant correlation both total cholesterol and systolic blood pressure, and a reversed correlation with HDL cholesterol in both sexes. %Fat of the group with ischemic findings in electrocardiogram was significantly higher than that of the group without those abnormaliies in the male, but such relation was not recognized in the female. Otherwise, in the male with hypertension, diabetes and other Internal diseases, %Fat was significantly higher than in the male without such diseases, and was significantly lower in the male with anemia. In the female, only the group with hypertension showed significantly higher %Fat compared with the group without any diseases. These results support the reported data in the city, in which the increase of body weight gave rise to the abnormal medical parameters.
