Prevalence of Chronic Obstructive Pulmonary Disease in the Portuguese Population
Sponsor: Sociedade Portuguesa de Pneumologia
Summary
The EpiCOPDpt Study (Prevalence of Chronic Obstructive Pulmonary Disease in the Portuguese Population) primary objective is to estimate the prevalence of Chronic Obstructive Pulmonary Disease (COPD) in the Portuguese population aged 20 and over. It is a cross-sectional study of a representative sample of the Portuguese population aged 20 and over, using standardised post-bronchodilator spirometry. Questionnaires will be applied to collect sociodemographic, economic, clinical, and therapeutic data.

Spirometry
Spirometry is a simple test used to diagnose and monitor lung diseases by measuring how much air a person can breathe out in one forced breath. After the baseline spirometry, and only if there is clear evidence of an airflow limitation/obstruction, i.e., if the FEV1/FVC (forced expiratory volume in the first second/forced vital capacity) ratio is less than 70% or less than the 5th percentile of the distribution of values measured in the reference population, a bronchodilator test will be performed using standardised post-bronchodilator spirometry (200 µg salbutamol), in order to identify persistent airflow limitation/obstruction.
