Abstract

Colorectal cancer (CRC) is the third most common type of cancer among both males and females in the United States and the second leading cause of cancer-related deaths. Although largely preventable through screening, early detection and removal of polyps, screening rates are considered sub-optimal. Perceived barriers to screening have been reported to influence screening rates. This paper examines variations in the extent to which uninsured patients identified barriers to CRC screening using colonoscopy based on race/ethnicity, educational attainment, age, gender, marital status and prior colonoscopy. Multivariate analyses showed that compared to Caucasians, African Americans had an increased likelihood of identifying lack of transportation as a barrier [odds ratio (OR) 2.68; 95 % confidence interval (CI) 1.35–5.32] while Hispanics were more likely to identify fear of finding cancer as a barrier (OR 2.09; 95 % CI 1.19–3.66). Compared to those with more than a high school education, there was increased likelihood of identifying lack of knowledge as a barrier among individuals with high school education (OR 3.51; 95 % CI 1.94–6.36) or less than a high school education (OR 2.16; 95 % CI 1.04–4.50). Our findings suggest that strategies aimed at increasing colonoscopy screening rates among underserved populations should take into consideration race/ethnicity, educational attainment, age, and prior colonoscopy experience when developing education and outreach plans to reduce barriers to colonoscopy.
