Little is known about the correlates of e-cigarette (EC) use among adults seeking smoking cessation treatment, and it is unclear how EC use affects smoking treatment outcomes.
Participants were 649 adult smokers enrolled in smoking cessation treatment. Participants completed a baseline (pre-quit) assessment with follow-up at 4-, 12-, and 26-weeks after a scheduled combustible cigarette (CC) cessation date. EC use was described before and after the CC cessation date, and the impact of baseline EC use on CC cessation at follow-up was evaluated.
At baseline, 66.6 % of participants had ever-used ECs and 23.1 % reported past 30-day EC use. Past 30-day EC users were younger, more socioeconomically disadvantaged, more CC dependent, and less likely to report Black race compared to non-users. At the 4-, 12-, and 26-week follow-ups, 6.4 %, 7.4 %, and 8.1 % reported dual EC/CC use; and 2.7 %, 3.4 %, and 2.7 % had switched to exclusive EC use. Past 30-day EC use at baseline was not associated with CC cessation at any follow-up. However, among baseline past 30-day EC users (n = 150), using ECs ≥ once per week was associated with a lower likelihood of CC cessation at 26-week follow-up (adjusted OR 0.346, 95 % CI: 0.120, 0.997).
Findings indicated that dual users of CCs and ECs at baseline differed from CC-only users on sociodemographic and smoking characteristics. Baseline EC use did not impact smoking cessation overall. However, among past 30-day users, more frequent EC use at baseline adversely impacted longer-term cessation outcomes, perhaps due to greater baseline CC/nicotine dependence.
人们对寻求戒烟治疗的成年人中电子烟（EC）使用的相关因素知之甚少，也不清楚 EC 使用如何影响吸烟治疗结果。
参与者为 649 名参加戒烟治疗的成年吸烟者。参与者在计划的可燃香烟（CC）戒烟日期后 4、12 和 26 周进行了基线（戒烟前）评估。描述了 CC 戒烟日期前后的 EC 使用情况，并评估了基线 EC 使用对随访时 CC 戒烟的影响。
基线时，66.6%的参与者曾使用过 EC，23.1%的参与者报告过去 30 天内使用过 EC。与非使用者相比，过去 30 天内使用 EC 的人年龄更小，社会经济地位更低，对 CC 的依赖性更强，报告为黑人的可能性更小。在 4、12 和 26 周的随访中，分别有 6.4%、7.4%和 8.1%的人报告同时使用 EC/CC；2.7%、3.4%和 2.7%的人转为仅使用 EC。基线时过去 30 天内使用 EC 与任何随访时的 CC 戒烟均无关。然而，在基线时过去 30 天内使用 EC 的人中（n=150），每周至少使用一次 EC 与 26 周随访时 CC 戒烟的可能性降低有关（调整后的 OR 0.346，95%CI：0.120，0.997）。
研究结果表明，基线时同时使用 CC 和 EC 的双重使用者在社会人口统计学和吸烟特征方面与仅使用 CC 的使用者不同。总体而言，基线 EC 使用并不影响戒烟。然而，在过去 30 天内使用 EC 的人中，基线时更频繁地使用 EC 会对长期戒烟结果产生不利影响，这可能是由于基线时 CC/尼古丁依赖性更高。
