Abstract PO-258: Cancer risk factors and screening across various U.S. rural classification codes: Cancer disparities in the context of rurality

Incidence and mortality of many preventable cancers are higher in rural compared to urban U.S. regions. However, prior research is limited by methodological inconsistencies in defining rurality, and has largely focused on a rural-urban dichotomy which ignores potential variability of cancer risk factors and outcomes within rural and urban settings. These limitations hamper data interpretation and may lead to inequitable distribution of resources to address disparities. In this study, we describe cancer risk factors and screening across various U.S. rural-urban classification codes to inform our understanding of cancer disparities across the rural to urban continuum. We examined the prevalence and trends in cancer risk factors and screening across the following rural-urban classification codes for counties and county-equivalents in 2013; U.S. Office of Management and Budget (OMB), National Center for Health Statistics (NCHS), U.S. Department of Agriculture, Economic Research Service’s rural-urban continuum codes (RUCC), and Urban Influence Codes (UIC). County-level data on demographics (age, race, education, income, poverty level, insurance status), and cancer risk factors (obesity, physical inactivity, alcohol consumption), including cancer screening (colorectal, cervical and breast) were obtained from the U.S. Census Bureau, Behavioral Risk Factor Surveillance System, and National Health Interview Survey from 2008-2013. Overall, rural counties’ populations were more likely to be older, white, and uninsured with lower educational attainment and household income than urban counties (all ptrend Citation Format: Kelly A.
