Objective: The objective of the study was to know the profile of patients diagnosed with chronic obstructive pulmonary disease (COPD) and who have never been smokers.
Design: A transversal study.
Location: Primary Care Centre of Pla d'Urgell (Primary care setting in Lleida, Spain).
Participants: 512 patients older than 40 years with COPD from Primary Care Centre of Pla d'Urgell with a compatible spirometry [forced expiratory volume in one second (FEV 1 )/forced vital capacity (FVC) ratio <0.7) to the beginning of the study.
Main Measurements: The dependent variable was de COPD in non-smokers and the independents were variables collected from the information on the respiratory clinical history, the risk factors of the patients and on quality of life. We designed a predictor model of COPD in non-smokers compared to smokers.
Results: 33.2% of COPD patients had never been smokers, 59.4% of whom were women. The average FEV 1 for non-smokers was 70.5 (SD=17.1), higher than 62.6 (SD=18.5) for smokers/former smokers (p<0.001). The coverage of pneumococcal vaccination 23V was better in non-smokers (75.3%), p<0.001. COPD in non-smokers (compared to smokers/former smokers) were: mostly women (OR=16.46), older (OR=1.1), with better FEV 1 (OR=1.1), better perception of quality, EuroQoL-5D (OR=0.8), with lower prevalence of diabetes (OR=0.5), lower level of studies (OR=0.2), and with fewer previous hospitalizations (OR=0.3).
Conclusions: The study evidences a high proportion of non-smokers in COPD patients. Our study aims that older women with less severity would be associated with an increased risk of COPD in non-smokers. It seems to indicate that COPD in non-smokers would appear at later ages and would be milder than smoking-related COPD.
