Race/ethnicity, sex and insurance disparities in colorectal cancer screening among individuals with and without cardiovascular disease.

Abstract

Colorectal cancer (CRC) and cardiovascular diseases (CVD) share several risk factors. We examined the relationships between CRC screening and CVD history by race/ethnicity and sex. Data from 15 states across the United States with high age-adjusted CVD rates from the 2012-2016 Behavioral Risk Factor Surveillance System were used to examine prevalence of self-reported screening for CRC among 179,276 adults ages 50-75years with and without history of CVD. Multivariable logistic regression was used to evaluate the association between socio-demographics and CRC screening in the expansion and stable phases of the Affordable Care Act (ACA) era. Prevalence of CRC screening was high among those with history of CVD. After multivariable adjustment, Whites and Hispanics with CVD had 19% (95%[CI]: 1.13-1.26) and 50% (95%[CI]: 1.10-2.06) higher odds for CRC screening, respectively, versus those without CVD. Individuals in both sexes with CVD had higher odds for CRC screening compared those without CVD. Strikingly, the odds for CRC screening in Hispanics with history of CVD were 72% higher in the stable phase of the ACA era for the fully adjusted model. Whites and Hispanics with history of CVD are more likely to undergo CRC screening, perhaps due to greater exposure to the healthcare system due to CVD. This association was not observed in Blacks. Interventions are needed to improve CRC screening rates among Blacks, especially due to their well-documented higher risk of CVD.
