E-cigarette use (i.e., vaping) is prevalent among young adults in the U.S. Studies show that young adults who vape are more likely to initiate cigarette smoking than young adults who do not vape. Despite this, little research on vaping interventions and prevention of smoking for young adults who vape exist.
A 2-arm pilot randomized controlled trial (RCT) will be conducted by recruiting young adults ages 18-24 who reported vaping at least once per week in the past 30 days and having never smoked cigarettes at baseline. Participants will be recruited via social media ads and be randomly assigned to an intervention arm, which will be the Live Free From E-cigarettes (LIFFE) mobile-based program (n = 50), or a waitlist control arm (n = 50). The primary outcomes are biochemically verified 7-day point prevalence abstinence for nicotine vaping, vaping reduction, and smoking susceptibility. Outcomes are measured at 2-, 4-, and 8-weeks after randomization.
This is the first RCT to evaluate the effectiveness of a mobile-based intervention that targets smoking susceptibility while also supporting vaping cessation or vaping reduction in young adults. Findings may inform future efforts to prevent transition to cigarette smoking and vaping cessation and reduction in young adults.

电子烟使用(即吸电子烟)在美国年轻人中很普遍。研究表明,吸电子烟的年轻人比不吸电子烟的年轻人更有可能开始吸烟。尽管如此,针对吸电子烟的年轻人的电子烟干预措施及吸烟预防的研究却很少。
将进行一项双臂试点随机对照试验(RCT),招募过去30天内每周至少吸一次电子烟且基线时从未吸过香烟的18至24岁年轻人。参与者将通过社交媒体广告招募,并随机分配到干预组,即基于手机的“摆脱电子烟自由生活”(LIFFE)项目(n = 50),或候补对照组(n = 50)。主要结局指标为经生化验证的尼古丁电子烟7天点流行率戒断、电子烟使用减少以及吸烟易感性。在随机分组后的第2周、第4周和第8周测量结局指标。
这是第一项评估基于手机的干预措施有效性的随机对照试验,该干预措施针对吸烟易感性,同时支持年轻人戒烟或减少电子烟使用。研究结果可能为未来预防年轻人过渡到吸烟以及戒烟和减少电子烟使用的工作提供参考。
