We estimated and analysised body height and body weight objecting 7,090 students of elementary, middle and high school (male; 3,730, female; 3,360) on the rural area (Ik-San, Wan-Ju, Im-Sil, Kim-Je, Ko-Chang) in Cheon Buk Province. We try to offer the basic data for correct program of counciling accordind to making a regression equtation in order to evaluate standard physique using this data. The results are the followings.
1. Physique Measurement
1) Body height is increased from 7 years old to 19 years old gradually, and the maximum growth age for a year is 11-12 years old (7.1cm) in boys, 9-10 years old (6.6cm) in girls. It appears that female is faster than male about 2 years. It appears that the cross periods of male and female is 9.5-12.5 years old, continues till 3 years.
2) The maximum growth age for a year in body weight is 11-12 years old in boys and girls, growing weight is 5.8kg and the cross periods of male and female continues till 2 years as 10.5-12.5 years old.
2. Regression Analysis on Body Weight to Body Height
1) Relative coefficient of body height and weight exists in the range r=0.629-0.844 in boys, r=0.457-0.800 in girls (P<0.001) according to ages.
2) The periods that regression coefficient make a peak is 12 years old in male (b-0.826), 13 years old in female (b=0.721)
3) According to the result of regression analysis on body weight to body height with age, the most increasing age on weight is 12 years in male (0.0826 kg/cm), and 13 years old in female (0.721 kg/cm) though the growing process.
