TUESDAY, May 15, 2018 (HealthDay News) — The prevalence of electronic cigarette (e-cigarette) ever use increased among U.S. adults from 2014 to 2016, according to a research letter published in the May 15 issue of the Journal of the American Medical Association<\/i>.<\/p>\n
Wei Bao, M.D., Ph.D., from the University of Iowa College of Public Health in Iowa City, and colleagues estimated the prevalence of ever and current e-cigarette use in 2014, 2015, and 2016. Data were analyzed for 101,175 National Health Interview Survey 2014 to 2016 participants aged 18 years or older.<\/p>\n
The researchers observed a significant increase in the prevalence of ever use of e-cigarettes from 2014 to 2016 (12.6 percent in 2014, 13.9 percent in 2015, and 15.3 percent in 2016; P for trend < 0.001). A significant increase was seen in almost all subgroups. From 2014 to 2016 there was a decrease in the weighted prevalence of current e-cigarette use (3.7 percent in 2014, 3.5 percent in 2015, and 3.2 percent in 2016; P for trend = 0.02). For individuals aged 65 years or older, women, non-Hispanic whites, low-income participants, and current cigarette smokers, the decrease was significant. Among former smokers and never smokers, the prevalence increased significantly.<\/p>\n
“In this study, current use of e-cigarettes declined among current smokers but increased among former smokers,” the authors write.<\/p>\n
