This study tries to show the physical growth patterns and various adolescent characteristics by using longitu-dinal data for the height, weight, chest girth and sitting height of 1,132 high school students in Seoul. And this study also tries to show what influencing factors on the physical growth of this aged population.
The followings are the results.
1. The boys have their peak velocity of height when they are 12~43 years old. And the girls have when they are 10~11 0years old. Peak´ velocity of weight for boys is at the age of 13~14. And for girls is at the age of ll~1 2. Peak velocity of chest girth for boys is at the age of 12~13. And for girls is at the age of 11-x12. Peak velocity of sitting height for boys is at the age of 13-14, And for girls is at the age of 11~13. So girls of this period grow more rapidly by around two years than boys.
2. The menarche of girls begins at the age of 12:4. So it begins 1.4 year before peak height ´velocity period.
3. Of life behavior boy’s contingency coefficient between essential time and height and weight is .5150 and .479 5, that between studying time and height and weight are .3344 and .2912(In case of girls is .4735, .4321, .324 7,3134).
