Colon cancer impacts nearly 2 million individuals in the U.S. each year. Early detection of colon cancer using colonoscopy can reduce the risk of mortality. The United States Preventive Services Task Force (USPSTF) recommends routine screening for colon cancer for all adults 50 to 75 years of age. Colon cancer screening behavior is different across a variety of predictor variables. Previous studies have identified older age, male gender, higher education, higher income, marriage, and the presence of chronic diseases to be associated with increased odds of colon cancer screening. However, less is known about the role of racial differences in screening. This study aims to determine if colon cancer screening rates are different between Whites and racial minorities in the United States controlling for potential confounders. This research can help bridge the existing gap on this topic and aid in identifying high-risk racial groups that could be targeted by future intervention strategies. We used cross-sectional data from the 2019 Behavioral Risk Factor Surveillance System, a nationally representative U.S. telephone-based survey of adults aged 18 years or older. We extracted data for adults age 50 or older (n=10,972). Logistic regression analyses were conducted to test the association between race and colon cancer screening. We also included chronic disease status, alcohol use, smoking, gender, and age in our model. Chronic disease status was coded as self-report 2 or more, 1 and 0 chronic diseases (referent), which included the summation of heart disease, hypertension, COPD, and diabetes. Overall, colon cancer screening is as follows among Whites (77.2%), Blacks (72.4%), Asian (60.1%), American Indian/Alaska Native (69.7%), and Hispanic (68.6%). Logistic regression results revealed that having 2 or more chronic diseases (OR=1.73; 95% CI 1.53,1.96), 1 chronic disease (OR=1.45; 95% CI 1.31,1.65), and female gender (OR=1.14; 95% CI 1.04,1.23) were associated with higher odds of screening. Race/ethnic minority status (OR=0.72; 95% CI 0.65, 0.81), low income (OR=0.64; 95% CI 0.57,0.70), and less than high school education (OR=0.71; 95% CI 0.59,0.84) were associated with lower odds of screening. Our research showed that racial minorities have lower odds of colon cancer screening after adjusting for gender, age, chronic diseases, income, and education status. Preventive practices should focus on increasing awareness on and availability of colon cancer screening means to racial minorities in the United States. Further research on the association between race and other screening modalities will help maximize the impacts of targeted interventions.
