Purpose: The burden of chronic obstructive pulmonary disease (COPD) is high in rural America. Few studies, however, have examined urban/rural differences in health care access, or racial/ethnic and income disparities stratified by urban/rural residence, among persons with COPD.
Methods: We studied individuals age ≥ 40 years with COPD from the 2018 Behavioral Risk Factor Surveillance System. The primary exposure was "urban" or "rural" county of residence. We examined multiple health and health care access/services outcomes using logistic regressions adjusted for age and sex, and performed analyses stratified by rural/urban county that included additional adjustment for race/ethnicity or income.
Findings: Our sample included 34,439 individuals. COPD prevalence was 8.6% in rural counties versus 5.4% in urban counties. Rural residents with COPD were poorer, had less education, worse health, and more disability. Of the rural population with COPD, 12.6% were uninsured, versus 10.4% in urban areas (AOR 1.26; 95% CI: 1.00-1.58). Rural residents with COPD were more likely to have not seen a doctor due to cost (AOR 1.18; 95% CI: 1.02-1.36). Differences in other outcomes were mostly nonsignificant. We observed large access disparities by race/ethnicity and income among individuals in both urban and rural counties, with the highest rates of forgone care among minorities in rural counties.
Conclusion: Patients with COPD in rural areas experience greater morbidity and obstacles to care than those in urban areas. Racial/ethnic minorities and those with low incomes-particularly in rural areas-are also at greater risk of forgoing doctor visits due to cost. Expanded access to health care could address respiratory health inequities.
