Abstract

|
|
A study on 4,609, (Boys: 2,563, Girls: 2,046) primary, middle and high school students in an urban area (Won Joo City) was conducted for assessing their physical growth, development, human body ;,surface area, body volume and a correlation and equation between body weight and body volume from April 1 to April 20, z1978, and the following results were obtained.
1. Physical Growth and Development.
a) Maximum growth was seen during the period from 10 to 15 years of age.
b) The maximum annual growth rates were as follows:
Body height: Boys-6.92cm from 15 to 16 years of age.
Girls-8.17cm from 10 to 11.
Body weight: Boys-5.7kg from 13 to 14
Girls-4.5kg from 12 to 13.
c) The greatest individual differences in growth and development were observed during 1114 years of age.
d) The standards of growth of rescent urban Korean students show much improved than that of 1967.
2. Body volume
Rapid growth, in terms of body volumes measured with both boys and girls of various ages, which is described by a straight line on a growth curve, has been observed among both of sexes in the age 6^´16, as in the case of body weight.
3. The Correlation between body weight and body volume
The correlation coefficients between body weight and body volume are indicative of highly correlated condition as follows; 6 year old; r=+0.997 (P<0.001) in male and r= +0.998 (p<0.001) in female.
