In an effort to evaluate the physical growth of children, the author conducted surveys for the past five years from 1971 to 1975 for 1, 297 children registered at Well ´Baby Clinic of Maigok Clinic, Thangjunmyon, Asan-kun, Chungnam province. The average values of the children´s height, weight, head and chest circumference were measured and analyzed in comparison with the Korean standard values prepared by the authorities concerned as follows.
1. Height
At the age of zero month, the average male children´s height was 50. 1cm, the female 50.0:m, while at the 24 months, the male 84.4cm and the female 80.9cm, respectively. The variation, compared with the Korean standard value, showed 1.0-2.0cm in male and 1. 5-2. 5cm in female. Bat the variation was not significant after 18 months in both sexes.
2. Weight
At the age of zero month, the average male children´s weight was 3.34kg and female 3. 27kg, and at the age of 24 months, male 11. 36kg, female 10. 86kg, respectively. The variation, compared with the Korean standard value, was greatest in 1 month. The growth pattern, after 5 months in male and 21 months in female, was faster than the average Korean standard pattern. Statistically, the variation was not significant after 5 months in male and 8 n onths in female.
3. Head circumference
At the age of zero month, the male children´s head circumference was 34.3cm in vale arc! 33. 7cm in female. The variation, in comparison with the Korean standard, was greatest in 1-2 months in both sexes. The gap showed a gradual decrease and the growth pattern of the male children after 12 months was faster than those of the Korean standard. But in the case of the female children, however, the growth pattern was slower and the variation became lessened. Statistically, the variation, in comparison with the Korean standard, was not significant after 12 months in both sexes.
4. Chest circumference
At the ale of zero month, the male children´s chest circumference was 33. 3cm and female 33. 0:m, while at the age of 24 months, male 50. 4cm and female 49. 2cm, respectively. From birth to 15 months, the growth pattern was slower than that of the Korean standard. Statistically, the variation was not significant after 12 months in male and 15 months in female.
5. As a whole, the growth pattern of the male children at the age of zero month was similar
to the Korean standard, while, the female children showed °rather slower patterns.At the age of 1 month, the growth pattern of both sexes showed retardation and then apprcached the Korean standard on the gradual basis. After the age of 12-18 months, the variation was not significant.
