Abstract Aims To provide up‐to‐date estimates of how changes in the prevalence of electronic cigarette (e‐cigarette) use in England have been associated with changes in smoking cessation activities and daily cigarette consumption among smokers in England. Design Time–series analysis of population trends. Setting England. Participants Participants came from the Smoking Toolkit Study, which involves repeated, cross‐sectional household surveys of individuals aged 16 years and older in England. Data were aggregated on approximately 1200 past‐year smokers each quarter (total n = 50 498) between 2007 and 2017. Measurements Prevalence of e‐cigarette use in current smokers was used to predict (a) prevalence of quit attempts among last‐year smokers, (b) overall quit rates among last‐year smokers and (c) mean cigarette consumption per day among current smokers. Prevalence of e‐cigarette use during a quit attempt among last‐year smokers was used to predict (a) quit success rate among last‐year smokers and (b) overall quit rates among last‐year smokers. Findings Overall quit rates increased by 0.054% [95% confidence interval (CI) = 0.032–0.076, P < 0.001] and 0.050% (95% CI = 0.031–0.069, P < 0.001) respectively for every 1% increase in the prevalence of e‐cigarette use by smokers and e‐cigarette use during a quit attempt. Quit success rates increased by 0.060% (95% CI = 0.043–0.078, P < 0.001) for every 1% increase in the prevalence of e‐cigarette use during a quit attempt. No clear evidence was found for an association between e‐cigarette use and either prevalence of quit attempt (BAdj = 0.011, 95% CI = −0.046 to 0.069, P = 0.698) or cigarette consumption (BAdj = 0.019, 95% CI = −0.043 to 0.082, P = 0.542). Conclusion Changes in prevalence of e‐cigarette use in England have been positively associated with the overall quit rates and quit success rates but not clearly associated with the prevalence of quit attempts and mean cigarette consumption.

英国电子烟使用流行率与戒烟和卷烟消费的关联:2006年至2017年的时间序列分析



摘要 目的 提供关于英国电子烟使用流行率变化与英国吸烟者戒烟活动和每日卷烟消费量变化之间关系的最新估计。设计人口趋势的时间序列分析。设置英格兰。参与者 参与者来自吸烟工具包研究,该研究涉及对英格兰 16 岁及以上个人进行重复的横断面家庭调查。 2007 年至 2017 年间,每季度汇总约 1200 名去年吸烟者的数据(总数 = 50 498)。测量当前吸烟者中电子烟的使用流行率用于预测 (a) 去年吸烟者中尝试戒烟的流行率,(b) 去年吸烟者的总体戒烟率和 (c) 当前吸烟者的平均每天香烟消费量。去年吸烟者尝试戒烟期间电子烟的使用率用于预测(a)去年吸烟者的戒烟成功率和(b)去年吸烟者的总体戒烟率。结果 每增加 1%,总体戒烟率就会分别增加 0.054% [95% 置信区间 (CI) = 0.032–0.076,P < 0.001] 和 0.050% (95% CI = 0.031–0.069,P < 0.001)。吸烟者使用电子烟的流行情况以及尝试戒烟期间使用电子烟的情况。尝试戒烟期间电子烟使用率每增加 1%,戒烟成功率就会增加 0.060%(95% CI = 0.043–0.078,P< 0.001)。没有发现明确的证据表明电子烟的使用与戒烟尝试率(BAdj = 0.011,95% CI = -0.046 至 0.069,P = 0.698)或卷烟消费率(BAdj = 0.019,95% CI = - 0.043 至 0.082,P = 0.542)。 结论 英国电子烟使用流行率的变化与总体戒烟率和戒烟成功率呈正相关,但与戒烟尝试流行率和平均卷烟消费量没有明显相关。
