Summary
Introduction:
This text is a summary of a research study investigating the association between secondhand nicotine vaping exposure and respiratory symptoms in young adults. The study is based on data from the Southern California Children's health Study cohort and includes repeated annual surveys from 2014 to 2019.
Key Points:
* Prevalence of secondhand nicotine vaping exposure increased from 11.7% to 15.6% during the study period.
* Prevalence of wheeze, bronchitic symptoms, and shortness of breath ranged from 12.3% to 14.9%, 19.4% to 26.0%, and 16.5% to 18.1%, respectively.
* associations were observed between secondhand nicotine vaping exposure and bronchitic symptoms (OR 1.40, 95% CI 1.06 to 1.84) and shortness of breath (OR 1.53, 95% CI 1.06 to 2.21) after controlling for relevant confounders.
* Stronger associations were observed when the analysis was restricted to participants who were neither smokers nor vapers.
* There were no associations with wheezing after adjustment for confounders.
Main Message:
The study found that secondhand nicotine vaping exposure was associated with increased risk of bronchitic symptoms and shortness of breath among young adults. These findings suggest that exposure to secondhand nicotine vaping may have negative impacts on respiratory health and provide a rationale for reducing home exposure to secondhand nicotine vaping and restricting vaping in public places.
