association between Electronic Cigarette Use and asthma in Never-Smokers.

Introduction:
This text discusses a study on the effects of electronic cigarette (e-cigarette) use on asthma in never-smokers. The study aims to examine the association between e-cigarette use and a self-reported diagnosis of asthma in a large, nationally representative sample of the U.S. population. The study also explores the relationship between frequency of e-cigarette use and reported asthma diagnosis.

Key Points:

* The study used data from the 2016 and 2017 Behavioral Risk Factor Surveillance System (BRFSS) surveys.
* Participants were considered never-smokers if they had not smoked at least 100 cigarettes in their entire life.
* Participants were categorized as never e-cigarette users, current e-cigarette daily users, current e-cigarette some-days users, and former e-cigarette users.
* The study found that current e-cigarette users had higher odds of reporting a diagnosis of asthma compared with never e-cigarette users.
* Daily e-cigarette users had a statistically significant odds ratio for asthma compared with never e-cigarette users.
* There was no statistically significant difference in the odds ratio of some-days users compared with never e-cigarette users.
* The study suggests that e-cigarette use may be associated with asthma among never-smokers.

Main Message:
The study found an association between e-cigarette use and asthma in never-smokers. Daily e-cigarette users had a statistically significant increased odds ratio for asthma compared with never e-cigarette users. These findings are critical as the prevalence of e-cigarette use among younger adults and adolescents is rising quickly while the prevalence of conventional cigarette smoking in this age group has declined. The study highlights the need for further research on the potential health risks of e-cigarette use.
