Increased detection rates of advanced colorectal adenoma in women with metabolic dysfunction-associated fatty liver disease

Abstract

Background: Metabolic dysfunction-associated fatty liver disease (MAFLD) is a new concept with its own diagnostic criteria. There are few studies on its relationship with colorectal adenoma. Objective: This study aimed to explore the relationship between MAFLD and colorectal adenoma and to compare the predictive value of MAFLD with other risk factors. Methods: A total of 4436 consecutive physical examination subjects were enrolled. They all underwent colonoscopy and abdominal ultrasound. MAFLD was diagnosed by both fatty liver disease and metabolic dysfunction. The correlation between colorectal adenoma and MAFLD was studied using a logistic regression model. Results: The prevalence of MAFLD was 31.72 % (1407/4436). The adenoma detection rate in MAFLD patients was higher than that in controls (13.50 %, 190/1407 vs. 10.70 %, 324/3029, p < 0.001). Univariate analysis indicated that MAFLD individuals were 1.303-fold as likely to have colonic adenoma as controls [odds ratio (OR) 1.303 and 95 % confidence interval (CI), 1.076–1.578, p = 0.007]. Multivariate analysis showed that age, male sex, BMI and smoking were positively associated with the risk of colorectal adenoma, with OR values of 1.044 (95 % CI, 1.031 to 1.058), 1.720 (95 % CI, 1.221 to 2.424), 1.046 (95 % CI, 1.009 to 1.085) and 1.342 (95 % CI, 1.072 to 1.680), respectively. MAFLD in women, but not in men, had an independent relationship with increased detection of advanced adenoma (OR 3.932, 95 % CI, 1.023–15.1117, p = 0.046). Conclusion: Individuals with MAFLD are more likely to develop colorectal adenoma than those without MAFLD. The influence of MAFLD on advanced colorectal adenoma was especially prominent in females.
