This study was performed to evaluate the prevalence and risk factors of colonic polyps which is an established premalignant lesion and to provide basic data for the management of colon cancer in asymptomatic adults. The subjects of this study were 995 persons who underwent screening colonoscopy between January to December 2010 in health promotion center of an University Hospital located in Busan, and structured questionnaire, medical questionnaire, medical records were reviewed retrospectively. The data were analyzed by SPSS 18.0 program. Colonic polyps were found in 63.2% of the subjects. The prevalence rate of colonic polyps was significantly higher in males and it increased with age. Age, sex and exercise were found to be related independently to colonic polyps. Early detection of colonic polyps by colonoscopy is important for adults over 40 years, and it is necessary to advise such subjects to correct a wrong life-style in order to primarily prevent the development of colonic polyps.
