A newly published study examined whether adolescent cigarette and e-cigarette use patterns over time differ by ethnicity. Data were pooled from three cohort studies of adolescents in California and Connecticut.
· Among non-Hispanic White (NHW) participants, ever e-cigarette or cigarette users at baseline (vs. never users) had significantly higher odds of past 30-day use tobacco use pattern at follow-up.
· Among Hispanic White (HW) participants, compared with never users, exclusive e-cigarette users at baseline had increased odds of continued e-cigarette use but not of transition to exclusive cigarette use at follow-up and HW exclusive cigarette users at baseline had greater odds of continued cigarette use but not of transition to exclusive e-cigarette use at follow-up.
Findings that NHW youth report more transitional use patterns and HW youth report more stable use patterns suggest a potential for differential impacts of e-cigarettes, by ethnicity, in increasing subsequent transition to or cessation from cigarette smoking.
