Notes from the Field: Use of Electronic Cigarettes and Any Tobacco Product Among Middle and High School Students a?? United States, 2011a??2018

摘要

Electronic cigarettes (e-cigarettes) are battery-powered devices that provide nicotine and other additives to the user in the form of an aerosol (1). E-cigarettes entered the U.S. marketplace in 2007 (1), and by 2014, e-cigarettes were the most commonly used tobacco product among U.S. youths (2). Data from the 2011–2018 National Youth Tobacco Survey (NYTS), a cross-sectional, voluntary, school-based, self-administered, pencil-and-paper survey of U.S. middle and high school students, were analyzed to determine the prevalence of current use (≥1 day in past 30 days) of e-cigarettes,* current use of any tobacco product,† frequency of (number of days during the preceding 30 days) e-cigarette use, and current use (any time during preceding 30 days) of any flavored e-cigarettes among U.S. middle school (grades 6–8) and high school (grades 9–12) students. Logistic regression (2011–2018) and t-tests (2017–2018) were performed to determine statistically significant differences (p<0.05).
