We examined the prevalence of COPD among never-smokers in Australia and identified associated risk factors.Methods: We used data from the Australia Burden of Obstructive Lung Disease (BOLD) study, a cross-section of people aged ≥ 40 years from six sites. Participants completed interviews and post-bronchodilator spirometry. COPD was primarily defined as an FEV1/FVC ratio < 0.70 and secondarily as the ratio less than the lower limit of normal (LLN).Results: The prevalence of COPD in the 1656 never-smokers who completed the study was 10.5% (95% CI: 9.1– 12.1%) [ratio
