All subjects underwent laboratory testing,abdominal ultrasonography,colonoscopy,and an interview to ascertain the baseline characteristics and general state of health. Multinomial logistic regression analysis was performed to examine the association between NAFLD and the prevalence of colorectal adenomatous and hyperplastic polyps.Furthermore,the relationship was analyzed in different sex groups. Subgroup analysis was performed based on number,size,and location of colorectal polyps.RESULTS The prevalence of colorectal polyps was 38.8% in males(16.2% for adenomatous polyps and 9.8% for hyperplastic polyps) and 19.3% in females(8.4% for adenomatous polyps and 3.9% for hyperplastic polyps). When adjusting for confounding variables,NAFLD was significantly associated with the prevalence of adenomatous polyps(OR = 1.28,95%CI: 1.05-1.51,P < 0.05) and hyperplastic polyps(OR = 1.35,95%CI: 1.01-1.82,P < 0.05). However,upon analyzing adenomatous and hyperplastic polyps in different sex groups,the significant association remained in males(OR = 1.53,95%CI: 1.18-2.00,P < 0.05; OR = 1.42,95%CI: 1.04-1.95,P < 0.05) but not in females(OR = 0.44,95%CI: 0.18-1.04,P > 0.05; OR = 1.18,95%CI: 0.50-2.78,P > 0.05). CONCLUSION NAFLD is specifically associated with an increased risk of colorectal adenomatous and hyperplastic polyps in men. However,NAFLD may not be a significant factor in the prevalence of colorectal polyps in women.展开更多
