Chronic obstructive pulmonary disease (COPD) affects many non-smokers, with risk factors including genetics and air pollution. Further research is needed to understand and reduce the global burden of COPD in never-smokers.
Area of Science:
- Pulmonology
- Environmental Health
- Epidemiology
Background:
- Chronic obstructive pulmonary disease (COPD) is a major global health issue, traditionally linked to smoking.
- Emerging evidence indicates a significant burden of COPD among non-smokers, previously underestimated.
- Understanding non-smoking-related COPD is crucial for comprehensive public health strategies.
Purpose of the Study:
- To highlight the prevalence and risk factors of COPD in non-smokers.
- To explore the diverse etiological factors contributing to non-smoking-related COPD.
- To emphasize the need for further research into this neglected aspect of COPD.
Main Methods:
- Review of existing literature on COPD in non-smokers.
- Identification and categorization of various risk factors.
- Analysis of regional variations and influencing factors.
Main Results:
- Approximately one-fourth of COPD patients are non-smokers.
- Identified risk factors include genetics, asthma, air pollution, biomass smoke, and infections.
- Significant regional variations in prevalence exist, influenced by local factors and study methodologies.
Conclusions:
- Non-smoking-related COPD is a substantial and underrecognized health problem.
- Multiple factors contribute to COPD development in never-smokers, varying by region.
- Further investigation is essential to effectively manage and reduce the global impact of COPD in non-smokers.

Chronic Obstructive Pulmonary Disease
Smoking is a primary risk factor for COPD, with over 80% of patients having a history of it. Patients typically experience progressive dyspnea or labored breathing, frequent coughing, and recurrent pulmonary infections. Many eventually succumb to respiratory failure, characterized by...
