Abstract:

Objective To investigate the risk factors that may be associated with colorectal polyps. Methods Patients who underwent complete colonoscopy at Peking Union Medical College Hospital endoscopy center between June 1, 2012 and May 31, 2013 were enrolled into this study. These patients were divided into polyps group and normal control group. Each case undertook the same questionnaire about their general situation and endoscopic polyps performance. The data were statistically analyzed by using SAS 9.2. Results Totally 106 colorectal polyps patients were enrolled into the polyps group and 383 normal persons were enrolled into control group. Multivariate logistic regression analyses were performed. Age (OR=1.343, 95%CI:1.063-1.697), family history of cancer (OR=3.013,95%CI:1.675-5.419) and high proportion of red meat intake (OR=1.650, 95%CI: 1.085-2.509) were independent risk factors for colorectal polyps. Adenomatous polyps was easier to be detected in male than in female (P<0.05) and the proportion of patients with adenomatous polyps increased with age (P<0.05). Conclusion Age, family history of cancer and high proportion of red meat intake are independent risk factors for colorectal polyps, while high proportion of fresh fruits and vegetables intake are protective factors. Elderly male patients may have increase risk to occur adenomatous polyps. Risk factors questionnaire is useful in screening for colorectal tumors.
