Abstract

Purpose: The purpose of this study is to clarify the traits of differences supposed as secular differences in physical growth between samples of children and youth in 1999 and 2005, and to identify the need of children and youth for health promotion. Methods: Two samples of different cohort were selected. The first one was consisted of 231 boys and 346 girls in 1999. And the other was consisted of 171 boys and 400 girls in 2005. Then the longitudinal growth distance data were collected from their cumulative health examination records. Results: The 2005 were larger in growth distances of stature, body weight, sitting height, and chest girth a at all ages from 6 to 16 in both boys and girls, so it could be concluded that a certain positive shift in growth process appeared in such a short duration. The 2005 were larger in growth velocity before peak age and also after peak age in body weight, but only in the term after peak age significant secular differences were found in stature for both sexes. As far as the growth distance concerned, the 2005 boys were ahead of the 1999 boys from 0.28-1.02 years and the 2005 girls from 0.32 to 0.81 years. In growth distance. Only in peak velocity, significant secular change was recognized in both sexes, any positive evidences of appearance of secular change were not found in peal age. In such derived physical indices as BMI, body weight index, sitting height index, and chest girth index, obvious evidences of secular change appearance were found.

연구목적: 본 연구는 1999년과 2005년의 다른 코호트에 있는 아동과 청소년 집단의 신체발육 특징을 비교분석함으로써 한국 아동과 청소년 신체발육의 단기적 시대변화를 파악하고자 하였다. 연구방법: 1999년 서울시 고등학교에 재학한 16세 남학생 231명, 여학생 346명과 2005년 서울시 고등학교에 재학한 16세 남학생 171명과 여학생 400명을 대상으로 이들의 건강검사 기록을 통해 종단적 신체발육자료를 수집하여 비교분석하였다. 연구결과: 주요 연구결과는 다음과 같다. 첫째, 남학생과 여학생 6세에서 16세까지의 모든 학생들의 2005년도 신장, 체중, 좌고, 흉위가 1999년에 비하여 더 컸다. 따라서 비교적 짧은 기간 동안에도 발육과정에 긍정적인 변화가 있음을 알 수 있었다. 둘째, 체중의 발육속도는 peak age이전이나 이후 모두 2005년이 컸으나, 신장은 peak age 이후에만 유의하게 컸다. 셋째, 2005년의 남학생들은 1999년에 비하여 신장은 평균 0.28년, 체중은 1.02년, 좌고는 0.39년, 흉위는 0.93년 앞서 있는 것으로 나타났다. 여학생의 경우, 신장은 0.81년, 체중은 0.76, 좌고는 0.32, 흉위는 0.57년 2005년이 앞서있었다. 즉, 2005년의 남학생들은 1999년에 비해 0.28-1.02년, 여학생들은 0.32-0.81년 발육이 앞서 있었다. 넷째, peak velocity에서만 남학생, 여학생 모두 유의한 시대적 변화가 있었고, peak age에서는 시대적 변화가 발견되지 않았다. 다섯째, BMI, 체중, 좌고, 흉위관련 지표에서 시대적 변화가 발견되었다. 특히 남학생의 경우는 체중, BMI, 흉위 관련지표에서, 여학생은 체중, 좌고에서 2005년과 1999년 간 유의한 차이가 발견되었다.
