It is important to study trends of e-cigarette use among various subgroups to understand which populations may be susceptible to their health effects.
We utilized cross-sectional data from the 2016 to 2017 Behavioral Risk Factor Surveillance System (BRFSS), a nationally representative U.S. telephone-based survey of adults 18 years or older. Current e-cigarette use was defined as use of e-cigarettes every day or some days. We analyzed data using survey weights as the BRFSS uses design weighting and iterative proportional fitting to ensure representativeness of the data to the US population. Test for trend was performed using ANOVA.
Our study population consisted of 28,917 current e-cigarette users corresponding to 10.8 million adults (30% 18–34 years, 49% men, 63% white, 12% black, and 17% Hispanic). The prevalence of current e-cigarette use increased from year 2016 to 2018 among adults 18–34 years (7.7% to 9.0%; p=0.25), former smokers (5.3% to 8.0%; p=0.02), users of other tobacco products (9.2% to 16.6%; p=0.03), and heavy alcohol users (8.6% to 10.6%; p=0.28) (Figure).
In a nationally representative sample, we found important trends in e-cigarette use in a relatively short time frame. Particularly, a significantly increasing prevalence of e-cigarette use was noted among former smokers and users of other tobacco products. Regulatory agencies can use this information to curb the marketing and sale of e-cigarettes to these susceptible groups.
