Abstract:
Objective To determine the risk factors related to the occurrence of colorectal adenomatous polyps and provide a basis for early screening, diagnosis, and treatment of colorectal cancer. Methods A total of 1 527 cases of colorectal polyps detected by colonoscopy were selected as the research subjects. Data on sociodemographic information, lifestyle and dietary habits, clinical history, laboratory tests, and endoscopic characteristics were collected. The patients were divided into adenoma and non-adenoma groups based on the pathological type. Multivariate logistic regression analysis was conducted to explore the influence of the above factors on the occurrence of colorectal adenoma. Results Old age (OR: 1.024, 95%CI: 1.001-1.048, P=0.044), high body mass index (OR: 1.046, 95%CI: 1.008-1.087, P=0.020), and a history of smoking (OR: 1.493, 95%CI: 1.035-2.158, P=0.032) were independent risk factors for the occurrence of colorectal adenoma. Patients with better cognitive function had a lower risk of developing colorectal adenoma than those with poorer cognitive function (OR: 0.929, 95%CI: 0.871-0.984, P=0.017). Polyps located in the rectum (OR: 0.396, 95%CI: 0.229-0.677, P=0.001) and those of flat type (OR: 0.531, 95%CI: 0.342-0.810, P=0.004) or laterally spreading type (OR: 0.306, 95%CI: 0.135-0.698, P=0.005) were more likely to be non-adenomatous polyps. The possibility of adenomatous pathological changes increased significantly with an increase in polyp size (OR: 1.063, 95%CI: 1.035-1.095, P<0.001). Conclusion Old age, high body mass index, smoking history, and large polyp diameters are related with a high risk of adenoma in the patients with colorectal polyps. Patients who have satisfactory cognitive function, polyps located in the rectum and polyps of flat type or laterally spreading type are likely to have non-adenoma.
