Abstract

In this study, physical growth and development were compared between Korean and Japanese youth and children ranging in age 6 to 14 years old. Longitudinal data were collected from the samples of both countries, which were comparable in socio-economical conditions. Korean sample was extracted from Seoul and Japanese from Tokyo. Stature, sitting height, body weight and chest girth were chosen as the variables to investigate the physical growth and development.
In general, Japanese boys and girls were larger in physique than the Korean until 6∼7 years old ; before growth spurt started, but thereafter, the Korean tended to be almost equal in body linearity to the Japanese and to be larger in body bulk than the Japanese.
For the peak velocity age, the korean boys were younger in sitting height and chest girth than the Japanese, and the Korean girls were younger in stature, body weight and sitting height. Thus, as long as compared in peak velocity age, the Korean were considered matured earlier than the Japanese. Then, the samples were classified into three maturation groups in reference with peak velocity age, and these maturation gorups were compared in physical growth between both countries. The significant differences were recognized between three maturation groups in both countreis. Then, the relative growth of body weight, sitting height, chest girth to stature, and that of chest girth to body weight were investigated.
