Summary
Introduction:
This text presents the study examining the association between e-cigarette use and chronic respiratory symptoms in young adults and never tobacco smokers. The study aims to clarify the role of age and concurrent tobacco smoking in the relationship between e-cigarette use and respiratory symptoms.
Key Points:
* The study analyzed data from the 2017 Behavioral Risk Factor Surveillance System (BRFSS) survey conducted by the CDC.
* E-cigarette use was defined as using e-cigarettes every day or some days, and the primary outcome was chronic respiratory symptoms, including daily cough, sputum production, or breathlessness during the past 3 months.
* after adjusting for sex, obesity, and cardiopulmonary disease, e-cigarette use was not associated with respiratory symptoms among current or recent-former smokers across age groups.
* however, e-cigarette use was associated with a higher prevalence of respiratory symptoms among younger never-smokers and remote-former smokers.
* across age groups, e-cigarette use was not associated with individual symptoms among current or recent-former smokers.
* among remote-former smokers >55 years of age, there was a lower prevalence of sputum production with e-cigarette use.
* The association of e-cigarette use with chronic respiratory symptoms among young never-smokers was primarily driven by a higher prevalence of cough.
Main Message:
The main message of the study is that e-cigarette use is associated with a higher prevalence of chronic respiratory symptoms among young never-smokers and remote-former tobacco smokers. The findings suggest that e-cigarette use may have detrimental effects on respiratory health, particularly in individuals with a lower background risk. The study highlights the importance of counseling patients, especially young adults, about the potential harm of e-cigarette use. Longitudinal studies are needed to understand the long-term risks of e-cigarette use among traditionally low-risk populations.
