국교 5년생의 성장발달에 관한 조사 연구 II. BMI 에 따른 저체중과 과체중의 요인분석

Study population was described at the previously published paper(23). Body Mass Index of 10751, 5th grade students from nation-wide were calculated . From this distribution lowest 10% and highest 10% were selected as group 1 and group 5, respectively. In this paper, between group 1 and group 5 anthropometric data, demographic data and other health related factors were compared. 1) Using Japanese criteria for obesity, the prevalence for obesity at 5 th grade was 5.8% at nation wide and 7.8% at urban area. 2) The proportion of students who skipped breakfasts everyday was 5.8% of whole student surveyed and 8.4% for group 5. The proportion of students who took medicine for health was 29.4% for group and 22.5% for group 5. 3) The students who are at group 5 had larger height and weight velocity than other groups. Group 5 had large increase of BMI by increasing grade, but group 1 had almost no change. 4) In physical fitness examination, group 3 who mean BMI was in the highest class than other groups 5 was in low class.

전보$^{23)}$에서 조사된 전국의 5학년생 10,751명의 BMI를 기준으로 하위 10%(1군)와 상위 10%(5군) 두군 간의 요인들을 비교 분석하였다. 1) 일본의 기준을 적용할 때 전국 5학년생의 5.8%, 도시지역의 7.8%가 비만에 해당하였다. 2) 거의 매일 아침을 먹지 않는 아동이 5.9%였으며 5군에서는는 8.4%로 매우 높았다. 1군에서는 29.4%, 5군에서는 22.5%가 건강을 위한 약제를 복용하였다. 3)5학년 때 BMI가 높은 군은 1학년 때 부터 연간키 성장폭이 컸으며 몸무게는 이런 경행이 더욱 두드러졌다. 5군은 학년이 올라가면서 BMI 값이 상당히 증가하였으나 1군은 변화가 거의 없었다. 4) 체력장 성적은 평균 집단인 3군에서 가장 좋았으며 5군에서 매우 낮았다.
