To examine the relationship between changes in electronic cigarette (e-cigarette) use and subsequent cigarette smoking cessation.
Using data from the Population Assessment of Tobacco and Health Study (wave 1-wave 4), we analysed a study cohort of 3014 current adult cigarette smokers at wave 1 who tried to quit during the past 12 months. We categorised changes in e-cigarette use from wave 1 to wave 2 as: daily initiation, non-daily initiation, increase to daily use, increase to non-daily use, stable daily use, stable non-daily use, decrease from daily use, quit non-daily use and non-use. We estimated multivariable logistic regressions on short-term (≥1 month and <12 months) cigarette smoking cessation at wave 3 and long-term (≥12 months) cigarette smoking cessation at wave 4. We conducted sensitivity analyses using alternative study cohorts.
Among the study cohort, 2.4% initiated daily, 7.5% initiated non-daily, 1.0% increased to daily, 1.4% increased to non-daily, 1.5% maintained daily, 3.0% maintained non-daily, 2.4% decreased from daily and 3.8% quit non-daily e-cigarette use between waves 1 and 2; 7.9% and 6.9% reported short-term and long-term cigarette smoking cessation. 15.1% of short-term and 16.3% of long-term cigarette quitters used e-cigarettes. Compared with non-users, smokers who initiated daily, increased to daily or quit non-daily e-cigarette use between waves 1 and 2 had higher odds of short-term cigarette smoking cessation at wave 3. These results are robust to different study cohort specifications.
The findings suggest a complex relationship between changes in e-cigarette use and subsequent cigarette smoking cessation.
研究电子烟使用变化与随后戒烟之间的关系。
利用来自人口烟草与健康评估研究（第 1 波至第 4 波）的数据，我们分析了第 1 波中试图在过去 12 个月内戒烟的 3014 名当前成年吸烟者的研究队列。我们将第 1 波至第 2 波期间电子烟使用的变化分为以下几类：每日开始使用、非每日开始使用、增加到每日使用、增加到非每日使用、稳定的每日使用、稳定的非每日使用、减少每日使用、停止非每日使用和不使用。我们在第 3 波估计了短期（≥1 个月且<12 个月）戒烟和第 4 波长期（≥12 个月）戒烟的多变量逻辑回归。我们使用替代研究队列进行了敏感性分析。
在研究队列中，有 2.4%的人开始每日使用，7.5%的人开始非每日使用，1.0%的人增加到每日使用，1.4%的人增加到非每日使用，1.5%的人维持每日使用，3.0%的人维持非每日使用，2.4%的人减少每日使用，3.8%的人停止非每日使用电子烟使用；7.9%和 6.9%报告了短期和长期戒烟。15.1%的短期戒烟者和 16.3%的长期戒烟者使用了电子烟。与非使用者相比，第 1 波至第 2 波期间开始每日使用、增加到每日使用或停止非每日使用电子烟的吸烟者，在第 3 波短期戒烟的可能性更高。这些结果在不同的研究队列特征下是稳健的。
研究结果表明电子烟使用变化与随后戒烟之间存在复杂的关系。
