Özet
Background: Few data are available on the epidemiology of COPD outside developed countries. Objectives: The objective of this epidemiological study was to assess the prevalence and burden of COPD, chronic bronchitis and smoking in eleven countries (Algeria, Morocco, Tunisia, Egypt, Jordan, Lebanon, Saudi Arabia, Syria, UAE, Pakistan and Turkey). Methods: A general population sample of 10 000 subjects ≥ 40yrs in each country was generated from random phone numbers. A structured interview was proposed to all subjects by telephone. Screening questions, including history of cough and sputum production, was used to identify subjects with chronic bronchitis. Individuals who smoked ≥ 10 pack-yrs and who had either chronic bronchitis or a previous diagnosis of COPD were considered to have possible COPD. In a subset of the study sample, assignment of COPD was confirmed by spirometry. This interim analysis assesses the prevalence of chronic bronchitis. Results: Of 118 039 subjects contacted, 44 892 were interviewed. 978 subjects reported having symptoms of chronic bronchitis. This corresponds to a prevalence of chronic bronchitis of 2.2% [95% CI: 2.0-2.3%], ranging from 0.6% [95% CI: 0.4-1.0%] in UAE to 2.9% [95% CI: 2.1-3.7%] in Algeria. The prevalence of chronic bronchitis was higher in women (2.4%; 95% CI: 2.2-2.6%) than in men (1.8%; 95% CI: 1.6-2.0%). Prevalence increased with age: 1.6% in subjects aged 40-49 yrs, 2.2% in those aged 50 to 59 yrs and 3.0% in those aged ≥ 60 yrs. Conclusion: The prevalence of chronic bronchitis in the Middle East and North Africa seems to be lower compared to other regions of the world.
