Abstract:Objective To investigate the epidemic status and influencing factors of colorectal polyps among urban residents in Lanxi.Methods A representative urban community was selected from Lanxi. A total of 935 local residents aged 18-80 years received questionnaire survey,physical examination,laboratory tests and colonoscopy. Multivariate Logistic regression analysis was applied to exam the potential influencing factors for colorectal polyps.Results Eventually 880 residents were involved into the statistical analysis. Colorectal polyps were detected in 167 participants with a crude prevalence of 18.98% and adjusted prevalence for age and gender of 13.28%. The prevalence of colorectal polyps in men(28.70%)was significantly higher than that in women(12.92%,P<0.05). The results of logistic regression analysis showed that age(OR=1.038,95%CI:1.018-1.057),males(OR=1.919,95%CI:1.303-2.826),the middle school level of education(OR=2.443,95%CI:1.507-3.961)and constitution of Yin-Asthenia(OR=0.203,95%CI:0.057-0.720)were influencing factors for colorectal polyps;among male participants,hypertension(OR=1.721,95%CI:1.018-2.908)was a risk factor for colorectal polyps;among female participants,age(OR=1.076,95%CI:1.042-1.111),BMI(OR=1.099,95%CI:1.001-1.207),the middle school level of education(OR= 3.507,95%CI:1.794-6.856)and constitution of Yin-Asthenia(OR=0.160,95%CI:0.033-0.770)were influencing factors for colorectal polyps.Conclusion Age,sex,education level and constitution of Yin-Asthenia were associated with the risk of colorectal polyps among residents in Lanxi;hypertension was associated with the risk of colorectal polyps in males,while age,BMI,education level and constitution of Yin-Asthenia were associated with the risk of colorectal polyps in females.
