Abstract

Chronic obstructive pulmonary disease (COPD) is a leading cause of morbidity and mortality worldwide. The prevalence of COPD among cigarette smokers in the Middle East is not well studied. A prospective descriptive study was performed in the north of Jordan. Male cigarette smokers (≥ 10 pack-year) aged 35 years and older were recruited from the community. They completed a questionnaire and a postbronchodilator spirometry. Global Initiative for Chronic Obstructive Lung Disease (GOLD) criteria (postbronchodilator forced expiratory volume in 1 second <70%) was used to define COPD. A total of 512 subjects completed the study protocol. According to the GOLD criteria, 42 subjects (8.2%) had COPD. Of those, 27 subjects (64.3%) had symptomatic COPD. Using the GOLD criteria, eight subjects (19%) with COPD had mild disease, 24 (57.1%) had moderate disease, eight (19%) had severe disease, and two (4.8%) had very severe disease. Only 10.6% were aware of COPD as a smoking-related respiratory illness, and 6.4% had received counseling about risk for COPD by a physician. Chronic bronchitis (cough for 3 months in 2 consecutive years) was reported by 15% of the subjects, wheezes by 44.1%, and dyspnea by 65.2%. Subjects with COPD reported having more chronic bronchitis 18/42 (42.9%) and wheezing 28/42 (66.7%) than subjects without COPD. The prevalence of COPD increased with increased number of pack-years smoked. In conclusion, COPD prevalence among cigarette-smoking men in Jordan is lower than in the developed world. COPD was largely underdiagnosed, despite the majority of participants being symptomatic and having moderate to severe disease.
