Abstract

The purpose of this study was to evaluate the relationship between Body Mass Index (BMI) and dental caries by considering related factors in Korean children and adolescents. A total of 2,874 children, aged from 2 to 18, who participated in the Korea National Health and Nutrition Examination Survey 2013 - 2015 were included. BMI ($kg/m^2$) was calculated, and participants were categorized into 4 groups using age and gender specific criteria. Decayed and filled teeth index were obtained. There were statistically significant differences in DMFT index between overweight group and other groups (p < 0.01). Underweight group showed the highest mean DMFT index compared to other groups. These findings suggest that children in obesity and underweight group tend to have more caries than normal group in this study.

2013년부터 2015년까지의 국민건강영양조사 6기의 자료 중 신체계측, 구강검사, 건강 설문조사를 시행한 2 - 18세의 소아청소년 2,874명을 2017 소아청소년 성장도표의 기준을 사용하여 체질량지수(Body mass index, BMI) 따른 4그룹으로 나누었다 : 비만그룹, 과체중그룹, 정상체중그룹, 저체중그룹. 각 그룹 간 우식치아수(dt, DT), 우식경험치아수(dft, DMFT)의 평균을 비교한 결과 비만그룹과 저체중그룹은 정상체중그룹보다 우식치아수와 우식경험치아수 모두에서 평균이 높았다. 과체중그룹은 우식치아수와 우식경험치아수의 평균값이 가장 낮았으며 다른 그룹과 유의한 차이를 보였다.
