Description

For the purpose of planning girls' clothes, longitudinal physical growth of 40 girls born in 1948 and 1949 were studied for 9 years after their entrance to primary school. The main results are : <BR>1. Treating longitudinally the data, the peak velocity is 8.7 cm at age 11.30 in stature, 5.4 cm at age 11.03 in lower limb length, and 4.1 cm at age 11.45 in upper limb length. The sequence of the maximum adolescent growth spurt of these items is lower limb length at first, stature and upper limb length.<BR>2. Comparing with the cross-sectionally treated results of the same group, the greater velocity per year at peak is obtained in the longitudinally treated results. The differences are 2.0 cm in stature, 1.3 cm in lower limb length and 1.1 cm in upper limb length.<BR>3. The average age of menarche is 11.26 for 38 girls, i. e. 1.38 year later the age at peak velocity of stature.
