    ABSTRACT: The EPI-SCAN study (Epidemiologic Study of COPD in Spain), conducted from May 2006 to July 2007, determined that the prevalence of COPD in Spain according to the GOLD criteria was 10.2% of the 40 to 80 years population. Little is known about the current geographical variation of COPD in Spain. We studied the prevalence of COPD, its under-diagnosis and under-treatment, smoking and mortality in the eleven areas participating in EPI-SCAN. COPD was defined as a post-bronchodilator FEV₁/FVC ratio <0.70 or as the lower limit of normal (LLN). The ratio of prevalences of COPD among the EPI-SCAN areas was 2.7-fold, with a peak in Asturias (16.9%) and a minimum in Burgos (6.2 %) (P<0.05). The prevalence of COPD according to LLN was 5.6% (95% CI 4.9-6.4) and the ratio of COPD prevalence using LLN was 3.1-fold, but with a peak in Madrid-La Princesa (10.1%) and a minimum in Burgos (3.2%) (P<0.05). The ranking of prevalences of COPD was not maintained in both sexes or age groups in each area. Variations in under-diagnosis (58.6% to 72.8%) and under-treatment by areas (24.1% to 72.5%) were substantial (P<0.05). The prevalence of smokers and former smokers, and cumulative exposure as measured by pack-years, and the age structure of each of the areas did not explain much of the variability by geographic areas. Nor is there any relation with mortality rates published by Autonomous Communities. There are significant variations in the distribution of COPD in Spain, either in prevalence or in under-diagnosis and under-treatment.

Se desconoce la variabilidad geográfica actual de la EPOC en España.ObjetivosDescribir la prevalencia de EPOC, su infradiagnóstico e infratratamiento, y los datos de tabaquismo y mortalidad en las once áreas participantes en el estudio EPI-SCAN. Se definió EPOC como un cociente FEV,/FVC posbroncodilatador < 0,70 o menor del límite inferior de la normalidad (LIN).ResultadosLa razón de prevalencias de EPOC según criterios GOLD entre áreas fue de 2,7 veces, con un máximo en Asturias (16,9%) y un mínimo en Burgos (6,2%) (p < 0,05). La prevalencia de EPOC según el LIN fue del 5,6% (IC 95% 4,9–6,4) y la razón de prevalencias utilizando el LIN fue de 3,1 veces, pero con un máximo en Madrid-La Princesa (10,1%) y un mínimo en Burgos (3,2%) (p < 0,05). El orden de prevalencias de EPOC por áreas no se mantuvo en ambos sexos ni por edades en cada área. Las variaciones en infradiagnóstico (58,6% a 72,8%) e infratratamiento por áreas (24,1% a 72,5%) fueron sustanciales (p < 0,05). La prevalencia de fumadores y ex-fumadores, y la exposición acumulada medida por paquetes-año, así como la estructura de edad de cada una de las áreas, no explican la variabilidad por áreas geográficas. Tampoco existe relación con las tasas de mortalidad publicadas por comunidad autónoma.ConclusiónExisten importantes variaciones en la distribución de la EPOC en España, tanto en prevalencia como en infradiagnóstico e infratratamiento.
