Although many studies have examined the association between e-cigarette use and smoking cessation, fewer have considered the impact of e-cigarette flavors on cessation outcomes. This study extends previous studies by examining the effects of e-cigarette use and e-cigarette flavors on quit attempts and quit success of smoking.
We used data from the 2018-2019 Tobacco Use Supplement-Current Population Survey (TUS-CPS) survey. Multivariate logistic regression analyses were used to investigate the associations between flavored e-cigarette use with quit attempts and quit success of smoking among individuals who smoked 12 months ago. Two current e-cigarette use definitions were used in these logistic regression analyses; currently use every day or some days versus 20+ days in the past 30 days.
Compared to those not using e-cigarettes, current every day or someday e-cigarette use with all nontobacco flavors had an adjusted odds ratio (AOR) of 2.9 (95% CI: 2.4 to 3.5) for quit attempts and 1.7 (95% CI: 1.3 to 2.2) for quit success. 20+ days e-cigarette use with flavors had stronger associations with quit attempts (AOR = 4.2, 95% CI: 3.1 to 5.5) and quit success (AOR = 4.0, 95% CI: 2.9 to 5.4). E-cigarette users with nontobacco flavors were more likely to succeed in quitting compared to those exclusively using non-flavored or tobacco-flavored e-cigarettes. Menthol or mint flavor users had slightly higher odds of quit attempts and success than users of other nontobacco flavors.
E-cigarette use is positively associated with both making smoking quit attempts and quit success. Those using flavored e-cigarettes, particularly menthol or mint, are more likely to quit successfully.
E-cigarette use is positively associated with both making a quit attempt and quit success, and those using flavored e-cigarettes are more likely to successfully quit smoking, with no statistically significant differences between the use of menthol or mint-flavored e-cigarettes versus the use of other nontobacco flavored products. This suggests that the potential for e-cigarettes to help people who currently smoke quit could be maintained with the availability of menthol or mint-flavored e-cigarettes, even if other nontobacco flavored products, which are associated with e-cigarette use among youth, were removed from the market.
尽管许多研究已经考察了电子烟使用与戒烟之间的关联，但很少有研究考虑电子烟口味对戒烟结果的影响。本研究通过考察电子烟使用和电子烟口味对过去 12 个月吸烟人群的戒烟尝试和戒烟成功的影响，扩展了之前的研究。
我们使用了 2018-2019 年烟草使用补充-当前人口调查（TUS-CPS）的数据。多变量逻辑回归分析用于调查过去 30 天内每天或某些天都使用调味电子烟与戒烟尝试和吸烟戒烟成功之间的关联。这两个当前电子烟使用定义用于这些逻辑回归分析；目前每天或有时使用与过去 30 天内 20 多天使用。
与不使用电子烟的人相比，使用所有非烟草口味的电子烟，每天或有时使用电子烟的调整后优势比（AOR）为 2.9（95%置信区间：2.4 至 3.5）用于戒烟尝试，1.7（95%置信区间：1.3 至 2.2）用于戒烟成功。使用有味道的电子烟 20 多天与戒烟尝试（AOR=4.2，95%置信区间：3.1 至 5.5）和戒烟成功（AOR=4.0，95%置信区间：2.9 至 5.4）的关联更强。与仅使用非风味或烟草风味电子烟的使用者相比，使用非烟草口味电子烟的电子烟使用者更有可能成功戒烟。薄荷醇或薄荷味使用者戒烟尝试和成功的几率略高于使用其他非烟草口味的使用者。
电子烟的使用与戒烟尝试和戒烟成功均呈正相关。使用调味电子烟，特别是薄荷醇或薄荷味电子烟，更有可能成功戒烟。
电子烟的使用与戒烟尝试和戒烟成功均呈正相关，使用调味电子烟的人更有可能成功戒烟，使用薄荷醇或薄荷味电子烟与使用其他非烟草口味产品之间没有统计学上的显著差异。这表明，即使从市场上移除了与青少年使用电子烟有关的其他非烟草口味产品，电子烟帮助目前吸烟的人戒烟的潜力也可以通过薄荷醇或薄荷味电子烟的可用性来维持。
