ABSTRACT
INTRODUCTION:
The prevalence of chronic obstructive pulmonary disease (COPD) varies significantly among the different geographical areas reported. In Spain, two epidemiological studies have shown a prevalence of 9-10% in the population aged over 40. However, neither of these studies included the Canary Islands, which are of interest due to their climatic conditions and high incidence of smoking. MATERIALS ANDMETHODS:
A random group of 1,353 subjects aged between 40 and 70years was selected from a sample population of 596,478 individuals. Participants completed a questionnaire and then performed spirometry with bronchodilator testing if obstruction was observed. COPD was diagnosed when the post-bronchodilator FEV1/FVC ratio was less than 0.70.RESULTS:
The prevalence of COPD was 7.3% (95%CI 5.5-9.5) and was higher in males than in females (8.7% vs. 6.3%, P=.134). The incidence of smoking was 29.4% (95%CI 25.4-33.1) and was also higher in males than in females (35.1% vs 25.4%, P<.001). The prevalence of COPD stratified by severity of obstruction, according to the GOLD criteria, was 16% in groupi, 69.9% in groupii, 10.4% in groupiii and 3.3% in groupiv. 71.6% of the subjects were underdiagnosed and 63.5% undertreated.CONCLUSIONS:
Despite having one of the highest rates of smoking in Spain, the prevalence of COPD in the Canary Islands is lower than in most of the Spanish regions studied.Palavras-chave
