Background: Among U.S. adults, over 4 million report a history of epilepsy, and more than 15 million report a history of chronic obstructive pulmonary disease (COPD); Chronic obstructive pulmonary disease, which includes chronic bronchitis and emphysema, is a common somatic comorbidity of epilepsy. This study assessed the relationship between self-reported physician-diagnosed epilepsy and COPD in a large representative sample of the U.S. adult population and explored possible mechanisms. Methods: Cross-sectional National Health Interview Surveys for 2013, 2015, and 2017 were aggregated to compare the prevalence of COPD between U.S. respondents aged >= 18 years with a history of physician-diagnosed epilepsy (n = 1783) and without epilepsy (n = 93,126). We calculated prevalence of COPD by age-standardized adjustment and prevalence ratios of COPD overall adjusted for sociodemographic and risk factors, by using multivariable logistic regression analyses. A Z-test was conducted to compare the prevalence between people with andwithout epilepsy at the statistical significance level of 0.05. Prevalence ratios whose 95% confidence intervals did not overlap 1.00 were considered statistically significant. Results: The overall age-standardized prevalence was 5.7% for COPD and 1.8% for epilepsy. Age-standardized prevalence of COPD among respondents with epilepsy (15.4%) exceeded that among those without epilepsy (5.5%). The association remained significantly different among all sociodemographic and risk factor subgroups (p < .05). In the adjusted analyses, epilepsy was also significantly associated with COPD, overall (adjusted prevalence ratio = 1.8, 95% confidence interval = 1.6-2.1) and in nearly all subgroups defined by selected characteristics. Conclusions: Epilepsy is associated with a higher prevalence of COPD in U.S. adults. Public health interventions targeting modifiable behavioral and socioeconomic risk factors among people with epilepsy may help prevent COPD and related premature death. Published by Elsevier Inc.
