Background: The prevalence of chronic obstructive pulmonary disease (COPD) in Abu Dhabi, United Arab Emirates is unknown.
Methods: We conducted a cross-sectional survey in a random sample of individuals 40-80 years old in Abu Dhabi, with a particular interest to explore local risk factors other than cigarette smoking. Airflow limitation compatible with COPD was defined as a post-bronchodilator ratio FEV(1)/FVC <0.
