Revealing the significance of early detection of chronic obstructive pulmonary disease: insights from healthy lung initiative data at COP27 conference.

Background: Climate change poses a significant threat to respiratory health, exacerbating conditions like asthma, Chronic Obstructive Pulmonary Disease (COPD), and respiratory infections increasing morbidity and mortality indirectly through exposure to greenhouse gases. During the 27th Climate Change Conference (COP27), the Healthy Lung Initiative (HLI) for the early detection of COPD among smokers was launched in Egypt.

Objective: We aimed to detect the prevalence and predictors of confirmed COPD among smokers and assess physicians' adherence to prescribing pulmonary function tests (PFTs) among the COP27 conference attendees.
