INTRODUCTION: Electronic cigarettes use is increasing in the United States. One motive for e-cigarette's popularity is that they wean from combustible cigarettes. Smokers perceive electronic cigarette products as healthier than cigarette smoking and as a useful tool for smoking cessation. However, research has indicated the use of electronic cigarettes may have harmful effects on respiratory function even with short-term use. Respiratory effects of e-cigarette use among asthmatics are little understood. OBJECTIVE: The aim of this study was to determine the association between e-cigarette use and frequency of asthma symptoms among adult asthmatics in California from 2015-2016. METHODS: This cross-sectional study included a total of 1277 adult asthmatics. The presence of asthma was based on an adult's self-reported doctor diagnosis. The analysis was controlled for age, education, sex, race, body mass index, and smoking status. RESULTS: = 0.162). CONCLUSION: Our findings suggest that e-cigarette use is associated with more frequent asthma symptoms and disproportionally affects male asthmatics.
