Abstract

As reported in the previous paper, the growth of the stature in urban boys and girls was superior in all ages to that in rural subjects . This report deals with skeletal age determined by X ray films of the left hand in 116 urban and 226 rural boys and girls aged from 6 to 15. Films of the subjects were referred to the Japanese standard films of bone development arranged by Dr. Inoue. There was no difference of skeletal age between urban and rural subjects although the stature of the former was superior to that of the latter by 3-10 cm. This facts means that rural boys and girls are equally maturated in the bone compared with urban subjects in spite of shorter stature of the former. Therefore, rural subjects may not be expected to be tall adults. Skeletal maturation is considered to be less influenced by postnatal environment compared with the physique and physical fitness .
