    Introduction: This study examined the association of spirometry-defined airflow obstruction and self-reported COPD defined as self-reported doctor diagnosed chronic bronchitis or emphysema, with occupational exposure among ever-employed US adults. Methods: Data were obtained from the National Health and Nutrition Examination Survey (NHANES) 2007–2008 to 2011–2012, a nationally representative study of the non-institutionalized civilian US population. Reported current and/or longest held job were used to create prevalence estimates and prevalence odds ratios (PORs) (adjusted for age, gender, race, and smoking status) for airflow obstruction and self-reported COPD by occupational exposure, determined using both NHANES participants’ selfreported exposures and eight categories of COPD job exposure matrix (JEM) assigned exposures. Results: Significant PORs for airflow obstruction and self-reported COPD respectively were observed with self-reported exposure for ≥20 years to mineral dust (POR = 1.44; 95% confidence interval (CI) 1.13–1.85; POR = 1.69; 95% CI 1.17–2.43) and exhaust fumes (POR = 1.65; 95% CI 1.27–2.15; POR = 2.22; 95% CI 1.37–3.58). Airflow obstruction or self-reported` COPD were also associated with COPD-JEM assigned high exposure to mineral dust, combined dust, diesel exhaust, vapor-gas, sensitizers, and overall exposure. Conclusion: Airflow obstruction and self-reported COPD are associated with both self-reported and JEM-assigned exposures.
