Study of Asthma and COPD in Workers at Navanakorn Industrial Zone, Thailand Observing Lung Health with Spirometry Testing

What this Trial Is About

Researchers are investigating how common asthma and chronic obstructive pulmonary disease COPD are among workers at the Navanakorn Industrial Zone in Thailand. This observational cross-sectional study focuses on Thai workers aged 18 years and older to understand the presence of these lung conditions in this population. Participants will be asked to complete a questionnaire about respiratory symptoms and will undergo pulmonary function testing using spirometry with a bronchodilator test. This test helps evaluate lung function to identify asthma, COPD, and other abnormalities. The study does not involve any treatment but collects diagnostic data at a single point in time. During the study, participants will provide information through questionnaires and undergo lung function tests. Researchers will measure the prevalence of asthma, COPD, and abnormal lung function among the workers. The study aims to provide important data about respiratory health in this industrial workforce. Participation involves completing the assessments and providing consent, with no ongoing treatment or follow-up required beyond the baseline visit.
