Discipline : EPI Epidémiologie / Epidemiology Domaine : Tabac / Tobacco Résumé : Background: Electronic cigarettes (e-cigarettes) are increasingly used by US adolescents and may be a gateway to traditional cigarette use. We examine rates of both products by age and examine differences in age-varying rates by sex and race/ethnicity.
Methods: Data are from the 2014 National Youth Tobacco Survey, a national sample of US middle and high school students (n = 22.007); students ages 11-19 were included. Past 30-day e-cigarette and traditional cigarette use were examined as a function of age; sex and race/ethnicity were included as moderators. The age-varying association between e-cigarette and traditional cigarette use was also examined.
Results: Rates of e-cigarette use increase faster than traditional cigarette use from ages 13-16. Compared to females, males had higher rates of e-cigarette use from ages 14-17.5 and traditional cigarette use from ages 15-18. Between ages 12-14, more Hispanic adolescents used e-cigarettes compared to White or Black adolescents; after age 14 Hispanics and Whites reported similar rates, peaking at twice the rate for Blacks. Hispanic adolescents report greater traditional cigarette use versus Whites between ages 12-13, but lower rates between ages 15-18. E-cigarette use was strongly associated with traditional cigarette use, particularly during early adolescence [OR > 40 before age 12].
Conclusions: Young Hispanic adolescents are at elevated risk for use of e-cigarettes and traditional cigarettes during early adolescence. During early adolescence, youth using e-cigarettes are more likely to smoke traditional cigarettes compared to youth not using e-cigarettes. The study of age-varying effects holds promise for advancing understanding of disparities in health risk behaviors.
An innovative method is used to examine age trends in adolescent e-cigarette use from a large, contemporary data set.
Rates of e-cigarette use increase faster than traditional cigarette use from ages 13-16.
Risk for e-cigarette use was higher for male and Hispanic adolescents at certain ages.
E-cigarette and traditional cigarette use were strongly associated throughout adolescence, particularly prior to age 15.

Discipline : EPI Epidémiologie / Epidemiology Domaine : Drogues illicites / Illicit drugs ; Tabac / Tobacco Résumé : Introduction: Electronic cigarette (e-cigarette) use prevalence is increasing among U.S. adolescents and adults but recent longitudinal data for college/university students are scarce. Furthermore, the extent that e-cigarette use is associated with the onset of cigarette smoking and the factors that lead to the uptake of e-cigarettes in college students has not been explored.
Methods: 3757 participants from a Mid-Atlantic university (women: 66%; White: 45%; Black: 21%; Asian: 19%; Hispanic/Latino: 6%) were surveyed in 2014 and again in 2015.
Results: Among participants reporting never smoking at time 1, those who had ever tried e-cigarettes or were currently using e-cigarettes (at least one use in past 30 days) were more likely to have ever tried cigarettes by time 2 relative to individuals who had not used e-cigarettes. Ever use of e-cigarettes (but not current use) also increased participants' likelihood of being current cigarette smokers at time 2. Among initial never users of e-cigarettes or cigarettes, males and ever marijuana users had an increased probability of trying e-cigarettes by time 2. Furthermore, less perseverance (an index of impulsivity) and ever use of other tobacco products increased initial never users' chances of trying both cigarettes and e-cigarettes by time 2.
Conclusions: Given that never-smoking participants who had tried e-cigarettes were more likely to initiate cigarette use later, limiting young adults' access to these products may be beneficial. As the long-term health implications of e-cigarette use become clearer, predictors of e-cigarette use could help identify future populations likely to use and abuse these products.
E-cig and cigarette use has not been studied in college students longitudinally.
Ever and current e-cig use increased non-smokers chances of trying cigarettes.
Historically internalizing/externalizing factors predict cigarette uptake strongly.
Most internalizing/externalizing factors examined did not predict e-cig uptake.
Males and marijuana users were more likely to initiate e-cig use.
