Association between rectosigmoid adenomas and cardiovascular risk factors: a hospital-based, cross-sectional study.

INTRODUCTION Little was known about the association between colorectal adenomas and cardiovascular risk factors in Taiwan. The aim of this study was to assess the association between rectosigmoid adenomas and related factors. MATERIALS AND METHODS This was a hospital-based, cross-sectional study. We analysed subjects receiving self-referred health examinations at 1 medical centre in Taiwan between 2001 and 2004. In total, 4413 subjects were enrolled in this study. There were 2444 men (55.4%) and 1969 women (44.6%). The mean age was 49.3 +/-12.3 years (range, 20 to 87). All subjects underwent a 60-cm flexible sigmoidoscopic examination and laboratory survey. Adjusted odds ratio (OR) and 95% confidence interval (CI) were expressed using a multivariate logistic regression analysis. RESULTS In the fi nal model, increasing age (OR, 1.05; 95% CI, 1.03-1.06), hypertriglyceridemia (OR, 1.49; 95% CI, 1.07-2.07), and alcohol consumption (OR, 2.11; 95% CI, 1.47-3.04) were the risk factors for rectosigmoid adenomas in men. Increasing age was the only risk factor for rectosigmoid adenomas in women (OR, 1.03; 95% CI, 1.01-1.06). CONCLUSION Age, hypertriglyceridemia and alcohol consumption are associated with rectosigmoid adenomas in men, and only age is significantly associated with rectosigmoid adenomas in women.
