Prevalence and influencing factors of colorectal polyps in Lanxi residents / 预防医学

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.
