Summary
Chronic cough affects 3% of Korean adults, impacting quality of life. Key challenges include an aging population and air pollution, with unmet needs in prevention and management.
Area of Science:
- Pulmonology and Epidemiology
- Public Health Challenges in Korea
Background:
- Chronic cough impacts 3% of Korean adults, significantly affecting quality of life.
- Korea faces unique challenges including a rapidly aging population and increasing air pollution.
- Current understanding of chronic cough causes and management in Korea has significant knowledge gaps.
Purpose of the Study:
- To review current epidemiological and clinical issues of chronic cough in Korea.
- To identify major knowledge gaps and future research priorities for chronic cough management.
- To provide perspectives on unmet needs in chronic cough prevention and treatment.
Main Methods:
- Review of epidemiological data on chronic cough prevalence in Korea.
- Analysis of clinical factors contributing to chronic cough, including airway diseases and GERD.
- Discussion of challenges posed by an aging population and air pollution.
Main Results:
- Upper and lower airway diseases account for approximately 75% of chronic cough cases.
- Gastroesophageal reflux disease (GERD) prevalence is increasing, requiring re-evaluation for cough relevance.
- 10-20% of chronic cough cases are refractory or unexplained, highlighting management difficulties.
Conclusions:
- Urgent research is needed to address the impact of aging and air pollution on chronic cough.
- Further studies are warranted for clinical uncertainty in evaluating and treating upper airway conditions.
- Re-evaluation of GERD and continued vigilance for infection-associated cough are crucial.
