摘要
Background and Aims:Colorectal cancer is associated with non-alcoholic fatty liver disease(NAFLD)and other metabolic syndromes,such as obesity,abnormal blood glucose,and dyslipidemia.The relationship of NAFLD and colorectal adenoma,which is the precursor of colorectal cancer,is worthy of discussion.The aim of this study was to investigate the association between colorectal adenoma and NAFLD,colorectal adenoma and metabolic syndrome in a Chinese Han population.Methods:This retrospective study analyzed the relationship between NAFLD and colorectal adenoma in 1089 patients in Qingdao municipal hospital.Subjects were divided into a colorectal adenoma group(n=267)and a control group(n=822).NAFLD and the controlled attenuation parameter(CAP)value were determined by abdominal ultrasound and FibroScan.Results:Patients with NAFLD in the colorectal adenoma group and the control group represented 142 cases(53.2%)and 360 cases(43.8%),respectively.The mean CAP value in the colorectal adenoma group was significantly higher than that in the control group.The values of body mass index,triglyceride,high-density lipoprotein cholesterol,aspartate aminotransferase,fasting plasma glucose,and uric acid were also significantly higher in the colorectal adenoma group than in the control group.Multifactor logistic regression analysis showed that the sex,NAFLD,CAP,body mass index,triglyceride,aspartate aminotransferase,and fasting plasma glucose were significant risk factors for colorectal adenoma.Besides,NAFLD and CAP value were significant risk factors for colorectal adenoma in males but not in females.Conclusions:NAFLD and metabolic syndrome were tightly associated with the risk of colorectal adenoma in this Chinese Han population.The effect of NAFLD on colorectal adenoma was prominent in males rather than in females.
