Abstract
1) Measurements of 900 school children in Fukushima City were made in July, 1966. The growth of their chest, waist and hip was investigated.
2) Hip growth with age is the largest among these three, next ranks chest, and the growth of waist is slowest. The maximum annual gain is observed with the boys in 7 th-8 th grade and girls in 5 th-6 th grade. Boys surpass girls in waist girth and girls excel in hip girth for all ages. No great difference exists in chest girth.
3) The value of depth/breadth increases gradually with age in chest, and gradually decreases in waist and hip chest thickens, and waist and hip broaden. The difference between waist girth and chest girth and also waist girth and hip girth become large, especially with girls. This, together with the change in the shape of chest, gradually constitutes the obvious sexual distinction.
4) The correlation of waist and hip girths to stature and that to chest girth are rather high (higher in the latter), because the examinees are children of growing ages.
