[Chronic obstructive pulmonary disease in inhabitants of Zabrze]

Abstract

In 2001 a modified MRC questionnaire and spirometry were performed in the inhabitants of Zabrze (Poland). Two hundred and thirty-nine men and 320 women aged 19-69 years were studied. Forty percent of men and 23% of women were smokers. In men but not in women a decline in smoking habit was observed as compared with previous studies in Zabrze carried out in the eighties. More men (32%) than women (19%) gave up smoking. The prevalence of chronic productive cough was closely related to smoking habit. Dyspnea and wheezing were also related to smoking but less strongly than productive cough. The prevalence of COPD (diagnosed according to GOLD criteria) was 10.2%. COPD was more common in smokers than in non-smokers, especially among men (19% and 2% respectively). Persistent productive cough, wheezing and advanced dyspnoea as well as intensive smoking (more than 40 pack years) were strongly connected with the prevalence of COPD. COPD was previously diagnosed in more than 50% of subjects identified as having COPD in this study. Almost 80% of subjects with COPD were not given any treatment in the past year.
