Characteristics of emerging adulthood and e-cigarette use: Findings from a pilot study

• 45% of participants reported lifetime and 12% reported past-month e-cigarette use.
• Themes of experimentation were associated with e-cigarette use.
• Those with fewer transitions were more likely to use e-cigarettes.
• Transitions in romance were positively associated with e-cigarette use.

IntroductionEmerging adults (ages 18 to 25) are more likely to use e-cigarettes compared to other age groups, but little is known about their risk and protective factors. A next step to understanding e-cigarette use among emerging adults may involve examining how transition-to-adulthood themes are associated with e-cigarette use. It may also be important to know which specific transitions, and how the accumulated number of role transitions experienced in emerging adulthood, are associated with e-cigarette use.MethodsEmerging adults completed surveys indicating their identification with transition-to-adulthood themes, role transitions in the past year, and e-cigarette use. Logistic regression models examined the associations between transition-to-adulthood themes and e-cigarette use. Separate logistic regression models explored the association between individual role transitions, as well as the accumulated number of role transitions experienced, and e-cigarette use, controlling for age, gender, and ethnicity.ResultsAmong the participants (n = 555), 21% were male, the average age was 22, 45% reported lifetime, and 12% reported past-month, e-cigarette use. Participants who felt emerging adulthood was a time of experimentation/possibility were more likely to report e-cigarette use. Several role transitions were found to be associated with e-cigarette use such as loss of a job, dating someone new, and experiencing a breakup. The relationship between the accumulated number of role transitions and e-cigarette use was curvilinear.ConclusionFindings from this pilot study can be a point of departure for future studies looking to understand the risk and protective factors of e-cigarettes among emerging adults.
