There is limited information about colorectal cancer (CRC) screening trends in high-risk groups, including the black, obese, diabetic, and smoking populations. For this study, the authors evaluated national CRC screening trends in these high-risk groups to provide insights into whether screening resources are being appropriately used.
This was a nationally representative, population-based study using the Behavioral Risk Factor Surveillance System from the Centers for Disease Control. Data analysis was performed using bivariate analyses with weighted logistic regression.
In the general population, CRC screening increased significantly from 59% to 65% during the years 2006 to 2010. The screening prevalence in non-Hispanic blacks was 58% in 2006 and 65% in 2010. Among obese individuals, the prevalence of up-to-date CRC screening increased significantly from 59% in 2006 to 66% in 2010. Screening prevalence in individuals with diabetes was 63% in 2006 and 69% in 2010. The CRC screening prevalence in current smokers was 45% in 2006 and 50% in 2010. The odds of CRC screening in the non-Hispanic black population, the obese population, and the diabetic population were higher than in non-Hispanic whites, normal weight individuals, and the population without diabetes, respectively. Current smokers had significantly lower odds of CRC screening than never-smokers in the years studied (2006: odds ratio [OR], 0.71; 95% confidence interval [CI], 0.66-0.76; 2008: OR, 0.67; 95% CI, 0.63-0.71; 2010: OR, 0.69; 95% CI, 0.66-0.73).
The prevalence of CRC screening in high-risk groups is trending upward. Despite this, current smokers have significantly lower odds of CRC screening compared with the general population. Cancer 2014;120:2106–2113. © 2014 American Cancer Society.
