Abstract

In order to assess the physical growth and development of primary school children in the Seoul Metropolitan area, I surveyed and tabulated the height, weight, chestgirth and sitting height of sixth grades in Seoul.
The survey sample was 3.386 children out of 7.201 eleven years-olds at 12 schools, including both public and private, in Seoul. I obtained the following results.
1. Height:
Body height development was devided as follows. The best was at private schools, reflecting a good home and adequate nutrition. The next was A class public school then B and C class in descending order.
From 6 years old boys and girls at neatly the same rate on a straight line pattern. The fastest growth occured at ages 10 to 11. In this term, girls began to grow taster than boys. The lines for boys and girls crossing. The rate of body growth was found tobe the same for Korea and Japan.
2. Weight:
As with height the average weight of pupils in private school was found to be greater than in public school.
Public schools ranked in descending order of A, B and C. From 6 years old weight increased gradually in a straight line development, with girls beginning to surpass boys at age 10 or 11 as with height. Both boys and girls gained weight at an accelated at this age. The comparison with Japanese children is similar, as with height.
3. Chest girth:
Little difference was discernible between public and private school and between boys and girls in the rate of growth of chestgirth. There was no crossing point in the rate between boys and girls.
Korean children were found to have slightly greater than Japanese children of the same age. The height rate of growth occured in the ages six to eleven.
4. Sitting height:
A comparison of the sitting of sixth grades produced exactly the same result as with body height. Children in private schools outranked those in public schools, which varied in descending order from A to C. Growth accelerated at the age 10 to 11, at which time girls grew faster than boys.
5. Relative body weight:
Relative body weight of private schools was better than public schools and developed in a straight line. The crossing point of boys and girls appeared at ages 10 and 11. at which point girls surpassed boys. Children living in better conditions outranked others.
6. Relative chestgirth:
Children in the out skirts of the city were best in relative chestgirth. Near to downtown, smaller and fatter bodies prevailed. The number of children with relatively narrow chests decreased from ages 6 to 11.
7. Relative Sitting Height:
Relative sitting height was greater in the outskirts than in the downtown area.
The opposite of relative weight was greater in outskirts area than in downtown. The best pettern for both boys and girls was at age six, becoming worse at late ages.
8.?? Index:
This feature is prevalent in the outskirts of the city. It is considered that this feature is due to the small and fat body type which prevailed downtown.
Boys as well as girls decreased from 6years old and the smallest occurance was among 11 years olds.
9. Kaup Index:
Higher downtown, decreasing toward the outskirts. The Kaup Index increased with age. For boys and girls´ age 6 to 11. it was under 2.0.
10. Boys and girls increase through all ages, were under 90 which was a sign of undernourishiment. The condition improved with better living conditions.
