- Conditions
- Chronic Obstructive Pulmonary Disease
- Registration Number
- NCT06523257
- Lead Sponsor
- Sociedade Portuguesa de Pneumologia
- Brief 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.

- Primary Outcome Measures
Name Time Method Individuals aged 20 years and over in the Portuguese population diagnosed with COPD(Chronic Obstructive Pulmonary Disease). Through study completion, an average of 10 months Number and proportion of individuals aged 20 years and over in the Portuguese population diagnosed with COPD.
- Secondary Outcome Measures
Name Time Method Individuals aged 20 years and over in the Portuguese population diagnosed with COPD (Chronic Obstructive Pulmonary Disease), by age group Through study completion, an average of 10 months Number and proportion of individuals aged 20 years and over in the Portuguese population diagnosed with COPD among males and females, within specific age groups (≥20, 20-29, 30-39, 40-49, 50-59, 60-69, and ≥70).
Individuals aged >20 years in the Portuguese population diagnosed with COPD (Chronic Obstructive Pulmonary Disease) by sex Through study completion, an average of 10 months Number and proportion of individuals aged 20 years and over in the Portuguese population diagnosed with COPD by sex: males and females.
Individuals diagnosed with COPD (Chronic Obstructive Pulmonary Disease) in each NUTS region Through study completion, an average of 10 months Number and proportion of individuals diagnosed with COPD in each NUTS region (Norte, Centro, Lisboa e Vale do Tejo, Alentejo, Algarve, Açores, and Madeira).
Sociodemographic profile of respiratory patients Through study completion, an average of 10 months A set of characteristics will be used to determine the sociodemographic profile: Sociodemographic characteristics:
* Age
* Sex
* Race
* Ethnicity
* Marital status
* Education level
* Socioeconomic status (income and living conditions) Number and proportion in case of categorical data and means, std dev and percentiles in case of continuous variables.Clinical profile of respiratory patients Through study completion, an average of 10 months A set of characteristics will be used to determine the clinical profile:
* Respiratory symptoms (such as cough, shortness of breath, and wheezing)
* Comorbidities (Yes, which?/No)
* Lung function tests (Spirometry will be carried out in accordance with the standard protocol of the joint ATS/ERS. The US Third National Health and Nutrition Examination Survey (NHANES III) values will be used as reference. Peripheral blood oxygen saturation (SpO2) will be assessed using a pulse oximeter)
* Anthropometric data: Weight in kilograms and height in meters. Weight and height will be combined to report BMI in kg/m\^2.
Number and proportion in case of categorical data and means, std dev and percentiles in case of continuous variables.Risk profile of participants Through study completion, an average of 10 months Characterisation of risk factors, such as smoking history, occupational exposures, air pollution exposure, genetic predisposition, and history of respiratory infections. Number and proportion in case of categorical data and mean, median, standard deviation, and percentiles in case of continuous variables.
