Purpose: Tobacco smoking is the major risk factor for COPD, and it is common for other risk factors in never- smokers to be overlooked. 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 [greater than or equal to]40 years from six sites. Participants completed interviews and post-bronchodilator spirometry. COPD was primarily defined as an [FEV.sub.1]/FVC ratio Results: The prevalence of COPD in the 1656 never-smokers who completed the study was 10.5% (95% CI: 9.1-12.1%) [ratio Conclusion: COPD was prevalent in this population of never-smokers aged 40 years and over. This finding highlights the significance of risk factors other than smoking in the development of COPD.
