초록

Characteristics of the subcutaneous fat distribution and some other anthropometric parameters were studied among 590 contemporary Korean youngsters(298 male and 292 female), randomly selected in Pusan and Kyungju areas.
1) In both male and female, the height and the weight of the body was markedly higher in high school(average age 17.2yrs) than in middle school(average age 14.4yrs) pupils, the difference being significantly greater in the former(17cm in height, 16kg in weight) than in the latter(5cm in height, 5.5kg in weight). However, between the high school pupil and the college student, there were no significant differences in the height and the wetght in both sexes.
2) Likewise, the mena subcutaneous fat thickness was significantly higher in the high school(3.86mm in male, 6.69mm in female) than in the middle school(2.86mm in male, 5.08mm in female) youngsters, but that in the college student(3.77 in male, 5.08 in female) was not higher than that in the high school pupil in both sexes. The absolute value of the mean subcutaneous fat thickness of the female was higher than that of the male by approximately 75% in the middle and high school pupils and 60% in the college students.
3) At all age groups, the local skinfold thickness at trunk and proximal limbs was higher than those at head and distal extremities in both sexes. However, at all regions of the body the skinfold thickness was much higher in the female than in the male, the difference being most significant at the abdomen and thigh.
4) The average surface area/mass ratio among middle school pupils was not significantly different between the male(0.0320m²/kg) and the female(0.0326m²/kg), but those in high school pupils and college students were approximately 4~7% higher in the male than in the female.
5) In all age groups, there was a negative correlation between the surface area/mass ratio and the mean subcutaneous fat thickness. The elevation of the regression line was higher in the female than in the male, especially in the high school and college students, thus at the same subcutaneous fat thickness the BSA/mass ratio was approximately 10% higher in the female than in the male.
These results indicate that in both male and female the increase in height, body weight and subcutaneous fat layer occurs until the high school period, and the higher subcutaneous fat thickness in females as compared to males among modern Korean youngsters is primarily attributed to the reater amount of fat distribution to the trunk and proximal extremities in females, which, in turn, suggest that the tolerance to cold stress is higher in the former than in the latter.
