METHODS: We conducted a retrospective cohort study using data from individuals who had multiple sigmoidoscopies for colon cancer at the Health Promotion Center of Ulsan University Hospital in Korea from 1998 to 2007. RESULTS: By multivariate analysis, the incidence of distal colon adenoma was increased by more than 1.76 times in individuals with at least one component of MS compared to those without a component of MS. After adjustment for age, gender, smoking, drinking, and physical exercise, only high body mass index (BMI) was significantly associated with the incidence of distal colon adenoma (Hazard ratio 1.66, 95% confidence interval 1.05-2.62). CONCLUSION: Our results suggest that high BMI may increase the risk of colorectal adenoma in Korean adults.展开更多

At present the cause of metabolic syndrome is unclear, it may come from two aspects： First, acquired, including being overweight or obese, reduced physical activity and excessive carbohydrate diet; Second, genetic factors, involving multiple genes, not yet fully elucidated. The syndrome is generally believed to be the collection of a variety of cardiovascular risk factors caused by poor lifestyle under the genetic background, including hypertension, dyslipidemia, abdominal obesity, hyperinsulinemia, microalbuminuria, hypercoagulable state, hyperhomocysteinemia and so on. Hyperinsulinemia and insulin resistance is the central link, which is closely related to dyslipidemia, impaired glucose tolerance, and abdominal obesity. Metabolic syndrome may eventually lead to atherosclerosis： coronary artery disease, myocardial infarction, stroke, peripheral vascular disease and endothelial dysfunction. In 1999, the working definition of World Health Organization （WHO） to the metabolic syndrome is： glucose regulation impairment or diabetes, and / or insulin resistance, accompanied by the other two items or more ingredients, such as hypertension, high triglycerides esters hyperlipidemia and / or low HDL cholesterol, central obesity or microalbuminuria.展开更多
