Abstract

The purpose of this study was to evaluate the relationship between obesity and dental caries in young children. The subjects were 769 children aged 3 to 6 years, in Iksan, Korea. Body mass index (BMI) and decayed and filled primary teeth (dft) were recorded. Children were classified into four groups (underweight, normal, obese at risk, and obese) according to their BMI percentile. The data of 754 participants, excluding 15 underweight children, were analyzed. The mean dft index was 3.39. There were no significant differences in the number of caries according to gender. The dft index increased significantly with age, with a sharp increase between ages 4 and 5. Children in the obese at risk and obese groups had more caries than those in the normal group. However, there were no statistically significant differences in dft index values between BMI-categorized groups except in 3-year-olds. These findings suggest that there is no significant connection between obesity and dental caries in primary teeth.

본 연구는 3-6세 어린이의 비만과 치아우식 사이의 관련성을 알아보고자 하였다. 익산시 소재의 어린이집과 유치원 아동 769명을 대상으로 우식경험유치지수(dft index)를 조사하고, 신장과 체중을 측정하여 체질량지수(body mass index)를 계산하였다. 표준성장도표의 체질량지수 백분위수를 이용하여 저체중, 정상, 비만위험, 비만의 4개 군으로 분류하였고, 저체중인 15명을 제외한 754명을 대상으로 분석하였다. 평균 dft index는 3.39였고, 남녀간의 유의한 차이는 없었다. 연령에 따라 dft index는 증가하였으며, 4세에서 5세에서 증가폭이 가장 컸다. 비만위험군과 비만군은 정상군보다 더 많은 우식경험률을 보였다. 그러나 3세 집단을 제외한 모든 연령군에서 정상, 비만위험, 비만 집단간의 통계적으로 유의한 차이를 보이지 않았다. 결론적으로 비만과 유치열의 우식경험에는 유의한 관련성이 없음을 알 수 있었다.
