E-cigarette use among women of reproductive age: Impulsivity, cigarette smoking status, and other risk factors

- Cigarette smoking was associated with impulsivity, lower education, drug use, and White race.
- E-cigarette use was associated with being a cigarette smoker and greater education.
- Among smokers, e-cigarette use was associated with nicotine dependence and quitting smoking.
- Among never smokers, e-cigarette use was associated with greater impulsivity and drug use.
- E-cigarette use was associated with use of other nicotine products.

IntroductionThe study aim was to examine impulsivity and other risk factors for e-cigarette use among women of reproductive age comparing current daily cigarette smokers to never cigarette smokers. Women of reproductive age are of special interest because of the additional risk that tobacco and nicotine use represents should they become pregnant.MethodSurvey data were collected anonymously online using Amazon Mechanical Turk in 2014. Participants were 800 women ages 24-44 years from the US. Half (n = 400) reported current, daily smoking and half (n = 400) reported smoking < 100 cigarettes lifetime. Participants completed questionnaires regarding sociodemographics, tobacco/nicotine use, and impulsivity (i.e., delay discounting & Barratt Impulsiveness Scale). Predictors of smoking and e-cigarette use were examined using logistic regression.ResultsDaily cigarette smoking was associated with greater impulsivity, lower education, past illegal drug use, and White race/ethnicity. E-cigarette use in the overall sample was associated with being a cigarette smoker and greater education. E-cigarette use among current smokers was associated with increased nicotine dependence and quitting smoking; among never smokers it was associated with greater impulsivity and illegal drug use. E-cigarette use was associated with hookah use, and for never smokers only with use of cigars and other nicotine products.ConclusionsE-cigarette use among women of reproductive age varies by smoking status, with use among current smokers reflecting attempts to quit smoking whereas among non-smokers use may be a marker of a more impulsive repertoire that includes greater use of alternative tobacco products and illegal drugs.
