Rural-urban disparities in health status among US cancer survivors

Abstract

Background: Although rural residents are more likely to be diagnosed with more advanced cancers and to die of cancer, little is known about rural-urban disparities in self-reported health among survivors.

Methods: The authors identified adults who had a self-reported history of cancer from the National Health Interview Survey (2006-2010). Rural-urban residence was defined using US Census definitions. Logistic regression with weighting to account for complex sampling was used to assess rural-urban differences in health status after accounting for differences in demographic characteristics.

Results: Of the 7804 identified cancer survivors, 20.8% were rural residents. This translated to a population of 2.8 million rural cancer survivors in the United States. Rural survivors were more likely than urban survivors to be non-Hispanic white (P < .001), to have less education (P < .001), and to lack health insurance (P < .001). Rural survivors reported worse health in all domains. After adjustment for sex, race/ethnicity, age, marital status, education, insurance, time since diagnosis, and number of cancers, rural survivors were more likely to report fair/poor health (odds ratio, 1.39; 95% confidence interval, 1.20-1.62), psychological distress (odds ratio, 1.23; 95% confidence interval, 1.00-1.50), ≥2 noncancer comorbidities (odds ratio, 1.15; 95% confidence interval, 1.01-1.32), and health-related unemployment (odds ratio, 1.66; 95% confidence interval, 1.35-2.03).

Conclusions: The current results provide the first estimates of the proportion and number of US adult cancer survivors who reside in rural areas. Rural cancer survivors are at greater risk for a variety of poor health outcomes, even many years after their cancer diagnosis, and should be a target for interventions to improve their health and well being.
