Patients who reported exercising one or more hours weekly had a lower prevalence of any polyps (25.3% vs 33.2%, P£¿=£¿0.008) as well as adenomas (13.8 vs. 18.9%, P£¿=£¿0.03) compared to those who did not exercise. Black and Hispanic patients and those who were overweight or obese also had lower prevalence of polyps if they led an active lifestyle. Multivariate analysis revealed that age >55, male sex, and Black race/ethnicity were positively associated with the presence of adenomas, while a history of exercising one hour or more weekly was an independent negative predictor for the presence of adenomas anywhere in the colon (OR 0.67; 95% CI 0.4 - 0.9, P£¿=£¿0.03).Exercising one hour per week was associated with a lower prevalence of polyps and adenomas when compared to those who exercised less or not at all. An active lifestyle provides benefits to groups who are at risk for colorectal cancer, such as Blacks. It also provides significant protection to overweight and obese individuals. Public health initiatives should promote physical activity as a cancer prevention tool in multiethnic populations.noneAs the second leading cause of overall cancer death in the United States, colorectal cancer (CRC) remains an important preventable public health concern. In 2010 an estimated 142,570 new cases of CRC were diagnosed and there were 51,370 associated deaths [1]. There are notable racial/ethnic differences in the epidemiology of the disease. The National Cancer Institute¡¯s 2007 Surveillance Epidemiology and End Results (SEER) Report determined a colorectal cancer incidence rate of 54.71/100,000 for Blacks versus 43.16 for Whites, 39.78 for Asians, and 35.84 for Hispanics [2]. Identifying modifiable factors that influence the epidemiology of colorectal cancer incidence among multiethnic groups might be informative for the development of public health strategies targeting the disease.Physical activity has bee %K Physical activity %K Colorectal polyps %K BMI %U http://www.biomedcentral.com/1756-0500/5/312
