[en] Study objetives: To determine the EPOC prevalence in Cambre, (Town of Coruña), given that there are few Spanish representative surveys that include this province. To study the EPOC prevalence in order to compare it among different countries and regions, due to the great morbimortality prevalence, to the high variation range among them, and due to the infradiagnosis and overdiagnosis which may occur because of a lack of functional test, (spirometry), which is a key tool to confirm or to rule out an EPOC diagnosis. To describe the low conformity between the medical record registry and the spirometry result, as well as the connection between the quality of life and health, and the EPOC. Methods: On a tansverse and stratified random sample of a 883 population of 65 years old and over, sociodemographic / clinical information was gathered, and a functional test (spirometry) was included and heath-life questionnaire (SF-36). This project has been carried out upon approval of Clinical Research Ethics committee of Galicia. The informed consent has been required by the patients. Results: The EPOC prevalence was a 14.2%, higher in men (11.7%), and it was age-related (18.2% in age group of 70-74 years old) and associated with tobacco use (40% in smokers). The previous diagnosis of EPOC was confirmed by Spirometry in 47.5% of the cases and more than half of the patients (52.5%) who shown that they had EPOC were ruled out by Spirometry. There is a low agreement between medical record registry and the spirometry result. The age, sex (Male), the smoking habit, shortness of breath, chronic cough and sputum are significantly associated to the EPOC presence. No significant differences were shown between the quality of life related to health and the presence or not of EPOC. CONCLUSIONS The EPOC prevalence is of 14.2%, more frequent in men than in women, it increases with age and the tobacco use and is measured by the index of packages/year.

[gl] Xustificación do estudo: Determinar a prevalencia da EPOC en Cambre, Municipio de A Coruña, dado que existen poucos estudos representativos españois que inclúan esta provincia. Contribuir a estudar a prevalencia da EPOC para así poder comparala entre diferentes países e rexións, debido a gran prevalencia de morbimortalidade, ao alto grao de variabilidade entre éstes e ao infradiagnóstico e/ou sobrediagnóstico que acontece pola falta de realización da proba funcional (Espirometría), ferramenta fundamental para confirmar ou descartar o diagnóstico da EPOC. Tamén describir a baixa concordancia entre o rexistro na historia clínica e o resultado da espirometría e relación entre a calidade de vida relacionada coa saude e a EPOC. Métodos: Sobre unha mostra aleatoria, estratificada, transversal, de base poboacional de 883 participantes de 65 anos e mais, recoulleuse información sociodemográfica/clínica, a cal incluía a realización dunha proba funcional (Espirometría), cuestionario de vida relacionado coa saude. (SF-36). O proxecto realizouse trala aprobación polo Comité Éti o de investigación clínica de Galicia . (Código do CEIC 2008/264). Solicitouse o consentimiento informado por parte dos pacientes Resultados: A prevalencia da EPOC foi do 14.2%, superior en homes (11,7%), e incrementouse coa idade (18,2% no grupo etario de 70-74 anos) e co consumo de cigarros (40% en fumadores). O diagnóstico previo da EPOC confirmouse por espirometria no 47,5% dos casos e máis da metade dos pacientes (52,5%) que reflectían que tiñan EPOC foron descartados por espirometria. Existe baixa concordancia entre o rexistro na historia clínica e o resultado da espirometria. A idade, o sexo (Masculino), o hábito tabáquico, o grado de disnea, tos crónica e expectoración asocianse significativamente á presencia da EPOC. Non se atoparon diferenzas significativas entre a calidade de vida relacionada coa saude e a presenza ou non de EPOC. Conclusións: A prevalencia da EPOC é do 14,2%, é máis frecuente en homes que en mulleres, aumenta coa idade e co consumo de tabaco medido polo índice de paquetes/ano.
