Abstract

BACKGROUND & AIMS:

Little is known about the effects of geographic factors, such as rural vs urban residence and travel time to colonoscopy providers, on risk-appropriate use of colorectal cancer (CRC) screening in the general population. We evaluated the effects of geographic factors on adherence to CRC screening and differences in screening use among familial risk groups.

METHODS:

We analyzed data from the 2010 Utah Behavior Risk Factor Surveillance System, which included state-added questions on familial CRC. By using multiple logistic regression models, we assessed the effects of rural vs urban residence, travel time to the nearest colonoscopy provider, and spatial accessibility of providers on adherence to risk-appropriate screening guidelines. Study participants (n = 4260) were respondents aged 50 to 75 years.

RESULTS:

Sixty-six percent of the sample adhered to risk-appropriate CRC screening guidelines, with significant differences between urban and rural residents (68% vs 57%, respectively; P < .001) across all familial risk groups. Rural residents were less likely than urban dwellers to be up-to-date with screening guidelines (multivariate odds ratio, 0.65; 95% confidence interval, 0.53-0.79). In the unadjusted analysis, rural vs urban residence (P < .001), travel time to the nearest colonoscopy provider (P = .003), and spatial accessibility of providers (P = .012) were associated significantly with adherence to screening guidelines. However, rural vs urban residence (P < .001) was the only geographic variable independently associated with screening adherence in the adjusted analyses.

CONCLUSIONS:

There are marked disparities in use of risk-appropriate CRC screening between rural and urban residents in Utah. Differences in travel time to the nearest colonoscopy provider and spatial accessibility of providers did not account for the geographic variations observed in screening adherence.
