Abstract

BACKGROUND: According to previous epidemiologic studies, the metabolic syndrome, dietary and lifestyle factors were associated with colon polyps. The aim of this cross-sectional study was to assess the relationship between the risk of the colorectal adenoma incidence and the individual components of the metabolic syndrome with lifestyle factors such as drinking, cigarette smoking and physical activity.
METHODS
Sigmoidoscopic examination for colon cancer screening was performed from January 2002 to December 2003 at the Health Promotion Center of Ulsan University Hospital in Ulsan, Korea. A total of 1,565 subjects underwent satisfactory sigmoidoscopy. The subjects with a history of colon cancer or polyps or inflammatory bowel disease were excluded from the study. Alcohol consumption, cigarette smoking and other confounding factors were included as covariates in the models.
RESULTS
After adjusting for age, physical activity,smoking and alcohol intake, the subjects of metabolic syndrome (> or =3 vs. 0 components) combined with cigarette smoking had a positive association with colorectal adenoma incidence (OR 3.63, 95% CI 1.49~8.89). Physical activity was negatively associated the risk of the colorectal adenoma incidence (OR 0.60 95% CI 0.44~0.81).
CONCLUSION
These results suggest that clustering of components of the metabolic syndrome combined with cigarette smoking significantly increased the colorectal adenoma risk, but physical activity reduced the risk of colorectal adenoma incidence in Korean adult males after multivariate adjustment.
