We examined past-12-month quit attempts and smoking cessation from 2006 to 2016 while accounting for demographic shifts in the US population. In addition, we sought to understand whether the current use of electronic cigarettes was associated with a change in past-12-month quit attempts and successful smoking cessation at the population level.
We analyzed data from 25- to 44-year-olds from the National Health Interview Survey (NHIS) from 2006 to 2016 (N = 26,354) and the Tobacco Use Supplement to the Current Population Survey (TUS-CPS) in 2006-2007, 2010-2011, and 2014-2015 (N = 33,627). Data on e-cigarette use were available in the 2014-2016 NHIS and 2014-2015 TUS-CPS surveys.
Past-12-month quit attempts and smoking cessation increased in recent years compared with 2006. Current e-cigarette use was associated with higher quit attempts (adjusted odds ratio [aOR] = 2.29, 95% confidence interval [CI] = 1.87 to 2.81, p < .001) and greater smoking cessation (aOR = 1.64, 95% CI = 1.21 to 2.21, p = .001) in the NHIS. Multivariable logistic regression of the TUS-CPS data showed that current e-cigarette use was similarly significantly associated with increased past-12-month quit attempts and smoking cessation. Significant interactions were found for smoking frequency (everyday and some-day smoking) and current e-cigarette use for both outcomes (p < .0001) with the strongest positive effects seen in everyday smokers.
Compared with 2006, past-12-month quit attempts and smoking cessation increased among adults aged 25-44 in recent years. Current e-cigarette use was associated with increased past-12-month quit attempts and successful smoking cessation among established smokers. These findings are relevant to future tobacco policy decisions.
E-cigarettes were introduced into the US market over the past decade. During this period, past-12-month quit attempts and smoking cessation have increased among US adults aged 25-44. These trends are inconsistent with the hypothesis that e-cigarette use is delaying quit attempts and leading to decreased smoking cessation. In contrast, current e-cigarette use was associated with significantly higher past-12-month quit attempts and past-12-month cessation. These findings suggest that e-cigarette use contributes to a reduction in combustible cigarette use among established smokers.
本研究旨在分析 2006 年至 2016 年期间美国人口结构变化的情况下，过去 12 个月的戒烟尝试和戒烟情况。此外，我们还试图了解当前电子烟的使用是否与人口层面上过去 12 个月戒烟尝试和成功戒烟的变化有关。
我们分析了来自国家健康访谈调查（NHIS）2006 年至 2016 年（N=26354）和 2006-2007 年、2010-2011 年和 2014-2015 年烟草使用补充调查（TUS-CPS）中 25-44 岁人群的数据（N=33627）。2014-2016 年 NHIS 和 2014-2015 年 TUS-CPS 调查中提供了电子烟使用数据。
与 2006 年相比，近年来过去 12 个月的戒烟尝试和戒烟率有所增加。目前使用电子烟与更高的戒烟尝试（调整后的优势比[aOR]=2.29，95%置信区间[CI]为 1.87 至 2.81，p<0.001）和更高的戒烟成功率（aOR=1.64，95%CI 为 1.21 至 2.21，p=0.001）相关，这在 NHIS 中得到了证实。TUS-CPS 数据的多变量逻辑回归显示，目前使用电子烟与过去 12 个月戒烟尝试和戒烟的增加显著相关。对于这两个结果，都发现了吸烟频率（每天和一些天吸烟）和当前电子烟使用之间的显著交互作用（p<0.0001），在每天吸烟的人群中观察到的影响最强。
与 2006 年相比，近年来，25-44 岁成年人过去 12 个月的戒烟尝试和戒烟率有所增加。目前使用电子烟与已经吸烟者过去 12 个月的戒烟尝试和成功戒烟有关。这些发现与未来的烟草政策决策有关。
电子烟在过去十年中被引入美国市场。在此期间，美国 25-44 岁成年人过去 12 个月的戒烟尝试和戒烟率有所增加。这些趋势与电子烟使用延迟戒烟尝试并导致戒烟率下降的假设不一致。相反，目前使用电子烟与过去 12 个月更高的戒烟尝试和过去 12 个月的戒烟率显著相关。这些发现表明，电子烟的使用有助于减少已经吸烟者对可燃香烟的使用。
