Abstract

Background/Aims: Obesity is a rising problem in industrialized countries. Numerous epidemiologic studies have shown a positive association between obesity and colorectal polyps. There are few studies investigating the association between colorectal adenomatous polyps and body fat composition in Korea. We tried to examine the relationship between body fatness and colorectal adenomatous polyps in health check-up subjects in Korea. Methods: Six thousand seven hundred and six routine health check-up subjects, who visited our hospital between March 2002 and April 2005 and underwent distal colon examimation with sigmoidoscopy, were enrolled in this study. Among them, colonoscopy was done in 860 patients to evaluate the entire colon. We tried to reveal the relationship between body mass index (BMI) and size, location, number and histopathological type of polyps. BMI was used as an indicator of obesity. Results: The mean value of BMI in total polyp-free group (23.8±2.9) was not different from that of the polyp group (24.5±2.8, p=0.09). The frequency of rectosigmoid polyps in obese patients (20.4%) was higher than that in non-obese patients (16.0%, p＜0.05). The frequency of adenomatous polyp was not different between obese and non-obese group. Number of polyps (≥4) correlated well with obesity. Moreover, age and triglyceride level in patients with colonic adenoma were significantly higher than in patients without colonic adenom. Conclusions: This study shows that obesity is not associated with colonic adenomatous polyp in Korean population. However, we observed that obesity may be associated with rectosigmoid colon polyps. Furthermore, age and triglyceride level might be the risk factors of colonic adenomatous polyps in Korean population.

목적: 대장암은 생활환경과 식생활의 변화와 더불어 최근 암 발생률, 사망률 모두 증가하고 있다. 이번 연구에서 대장암의 전구 병소로 잘 알려진 선종용종과 체질량지수를 이용한 비만과의 연관성에 대해 알아보고 대장 용종의 수, 크기, 조직 분류와 생화학검사 수치들을 비교하였다. 대상 및 방법: 2002년 3월부터 2005년 4월까지 분당서울대병원의 건강증진센터를 방문한 검진자에서 에스자결장경 검사를 시행했던 환자 6,706명과 이 중 대장내시경을 시행한 860명을 후향으로 분석했다. 체질량지수가 25 이상인 군을 비만군, 25 미만인 군을 대조군으로 정하였다. 이외의 변수로는 성별, 연령, 콜레스테롤, 중성지방, 당화혈색소, 고밀도지질단백, CRP 등이 있으며 이들과 함께 대장 용종의 육안 및 조직병리분류, 용종의 해부학 분포, 크기와 수 등을 체질량지수와 비교하였다. 결과: 대상 환자의 평균 연령은 51.1±10.5세 였으며 연령분포는 18세에서부터 83세 사이였다. 남녀 비는 1.1:1이었다. 선종 빈도는 정상군 16.0%과 비만군 20.4%로 유의한 차이를 보였다. 대장내시경을 시행한 860명을 용종군과 대조군으로 나누어 비교하였을 때 대장 용종의 유무에 따른 체질량지수의 평균은 대조군에서 23.9±2.8, 용종군에서 24.3±2.8로 차이를 보이지 않았고 용종 크기에 따른 체질량지수 차이도 없었다. 체질량지수에 따른 대장 선종 빈도는 정상군에서 32.5%였으며 비만군에서는 38.5%로 차이를 보이지 않았으며, 관상선종군과 융모선종군의 체질량지수의 평균치는 각각 24.3±2.7, 24.4±3.1로 통계적인 유의성은 없었다. 그러나 대장내시경 검사에서 선종 수가 4개 이상으로 증가하는 경우 체질량지수와 유의한 관계를 보였다. 이 외에 연령, 중성지방은 대장 용종의 유무에 따라 의미있는 차이를 보였다. 결론: 대장 선종 유무에 따른 체질량지수의 차이는 관찰되지 않았으나 대장 선종 수가 증가할수록 체질량지수의 차이가 있었으며 연령, 중성지방 등도 대장 선종 발생의 위험요소일 수 있음을 확인하였다.
