Sharapova SR, et al. - E-cigarette use frequency was evaluated by sociodemographic characteristics and other tobacco product use among U.S. adults. The researchers found variations in the frequency of e-cigarette use by sociodemographic characteristics and other tobacco use. Further surveillance, especially related to the frequency of e-cigarette use and its effect on cigarette cessation, could inform public health policy, planning, and practice.

Methods

• The researchers examined combined data from the 2012-2013 (n=60,192) and 2013–2014 (n=75,233) National Adult Tobacco Survey, a telephone-based survey of U.S. adults aged ≥18 years.
• The purpose was to evaluate the frequency of e-cigarette use (daily, some days, rarely) by sex, age, race/ethnicity, education, annual household income, U.S. region, marital status, sexual orientation, and cigarette smoking and other tobacco product use (cigars, cigarillos, little filtered cigars; traditional pipes; water pipes; and chewing tobacco, snuff, dip, snus, and dissolvable tobacco products).
• This study was performed in 2016.

Results

• In this study, 19.3% used daily, 29.3% used some days, and 51.4% used rarely among current e-cigarette users.
• Among younger adults, Hispanics, and those who were single, never married, or not living with a partner, the daily use was reported to be lowest.
• It was greatest among non-Hispanic Asians (p<0.0001).
• Cigarette-only smokers were found to be 25.3%, 52.8% subjects smoked cigarettes and used other tobacco products, 5.5% used other tobacco products only, 6.5% were former cigarette-only smokers, 6.7% were former users of cigarettes and other tobacco products, 1.3% were former other tobacco product users only, and 1.8% never used cigarettes or other tobacco products among current e-cigarette users.
