Background: Colon cancer is believed to develop from colon polyps. Early detection of colon polyps and identification of risk factors will decrease theprevalence of colon cancer. The purpose of this study was to determine whether age, body mass index (BMI), and dyslipidemia are risk factors for thedevelopment of colon polyps. Methods: In this study, we included 2,477 patients who underwent colonoscopic examinations and BMI measurements, including waist circumference,between January 2016 and December 2018 at the health promotion center of Dongsuwon Hospital in Suwon. We analyzed the relationshipsbetween the risk factors and colon polyp formation by using an age-adjusted multiple regression analysis. Results: The prevalence of colon polyps was 14.3% (n=353) and was significantly higher in the older age group (P<0.05). No association was foundbetween the risk of colon polyp formation and the levels of total cholesterol and low-density lipoprotein. However, high-density lipoprotein leveland BMI showed a relationship with the prevalence of colon polyps. Conclusion The development of colon polyps was associated with obesity rather than dyslipidemia in the asymptomatic healthy adults in this study.
