For the measurement on the fat content in primary and middle school students was conducted on a total of 810 students (male 458, female 352), from 6 to 15 years of age.
The subjects were all students in the Young Yoo Island, Young Yoo Myun, Bu Chun Kun, Gyunggi-Do total body fat amount was measurement by skin fold thickness with a skin-fold caliper (manufactured by Cambridge Scientific Industrial Inc. U.S.A) at four sites of the body, and it was calculated by Keys and Brozek´sl2), Nam´s36), and Kim´s26)37) regression equation.
As a result of this survey, the following conclusions were obtained.
1. At the same age skin-fold thickness on all sites were greater in girls than boys.
2. The mean value of skin-fold thickness: The average value of the whole body´s as well as from four parks (scapular, abdominal, lumbar, upper arm) of the body are much lower than the students in urban but similar to those of students from rural area.
3. By the regression equation of the body fat weight: The students nutritional condions are as follows: Fat weight (kg), fat free weight (kg), fat weight/total body mass (%), fat free weight/tota 1 body mass (%), fat weight/Fat free weight (%), as well as on the whole of the student´s nutritional condions are much lower than the student´s in urban.
