Objective To examine trends in long term (>6 months) vaping among adults in England. Design Population based study. Setting England. Participants 179 725 adults (≥18 years) surveyed between October 2013 and October 2023. Main outcome measures Time trends in prevalence of long term vaping using logistic regression, overall and by vaping frequency (daily or non-daily), and main type of device used (disposable, refillable, or pod). Results The proportion of adults reporting long term vaping increased non-linearly, from 1.3% (95% confidence interval 1.1% to 1.5%) in October 2013 to 10.0% (9.2% to 10.9%) in October 2023, with a particularly pronounced rise from 2021. This rise included an increase in long term daily vaping, from 0.6% (0.5% to 0.8%) to 6.7% (6.0% to 7.4%). Absolute increases in long term vaping were larger among people with a history of regular smoking (current smokers: 4.8% (4.0% to 5.8%) to 23.1% (20.4% to 25.9%); recent former smokers: 5.7% (3.4% to 9.2%) to 36.1% (27.6% to 45.4%); long term former smokers: 1.4% (1.0% to 1.9%) to 16.2% (14.2% to 18.4%)), but an increase also occurred among people who had never regularly smoked (0.1% (0.0% to 0.2%) to 3.0% (2.3% to 3.8%)). Growth was also more pronounced in young adults (eg, reaching 22.7% (19.2% to 26.5%) of 18 year olds v 4.3% (3.6% to 5.2%) of 65 year olds), including among those who had never regularly smoked (reaching 16.1% (11.1% to 22.7%) of 18 year olds v 0.3% (0.1% to 0.6%) of 65 year olds). Between October 2013 and March 2021, most long term vapers mainly or exclusively used refillable electronic cigarettes (2.5% to 3.3% of adults) and few (0.1% of adults) used disposable devices. However, prevalence of long term vaping using disposable devices subsequently rose rapidly, and by October 2023 similar proportions of adults mainly or exclusively used disposable and refillable devices (4.9% (4.2% to 5.7%) and 4.6% (4.0% to 5.3%), respectively). Conclusions The prevalence of long term vaping increased substantially among adults in England during 2013-23. Much of this increase occurred from 2021, coinciding with the rise in popularity of disposable e-cigarettes. Half of long term vapers now mainly or exclusively use disposable devices. The growth was concentrated among people with a history of regular smoking, but an increase also occurred among people who never regularly smoked, especially young adults.

2013-23 年英国成年人长期吸电子烟的趋势：基于人群的研究


目的 研究英格兰成年人长期（>6 个月）吸电子烟的趋势。设计基于人群的研究。设置英格兰。参与者在 2013 年 10 月至 2023 年 10 月期间对 179 725 名成年人（≥ 18 岁）进行了调查。 主要结果指标 使用 Logistic 回归得出长期电子烟流行率的时间趋势，总体和电子烟频率（每日或非每日）以及主要设备类型使用过的（一次性、可再填充或烟弹）。结果 报告长期吸电子烟的成年人比例呈非线性增长，从 2013 年 10 月的 1.3%（95% 置信区间 1.1% 至 1.5%）增加到 2023 年 10 月的 10.0%（9.2% 至 10.9%），增长尤为明显从 2021 年开始。这一增长包括长期每日吸电子烟的比例从 0.6%（0.5% 至 0.8%）增加至 6.7%（6.0% 至 7.4%）。有经常吸烟史的人长期吸电子烟的绝对增加幅度更大（当前吸烟者：4.8%（4.0%至5.8%）至23.1%（20.4%至25.9%）；最近吸烟者：5.7%（3.4%至25.9%）；最近吸烟者：5.7%（3.4%至25.9%） 9.2%）至36.1%（27.6%至45.4%）；长期吸烟者：1.4%（1.0%至1.9%）至16.2%（14.2%至18.4%）），但从未吸烟者中也出现了增加经常吸烟（0.1%（0.0%至0.2%）至3.0%（2.3%至3.8%））。年轻人的增长也更为明显（例如，18 岁人群中这一比例达到 22.7%（19.2% 至 26.5%），65 岁人群中这一比例为 4.3%（3.6% 至 5.2%）），其中包括那些从未经常吸烟的人群。 18 岁人群中这一比例为 16.1%（11.1% 至 22.7%），而 65 岁人群中这一比例为 0.3%（0.1% 至 0.6%）。 2013 年 10 月至 2021 年 3 月期间，大多数长期电子烟使用者主要或专门使用可再填充电子烟（占成人的 2.5% 至 3.3%），少数人（占成人的 0.1%）使用一次性电子烟。 然而，使用一次性设备长期使用电子烟的流行率随后迅速上升，到 2023 年 10 月，主要或专门使用一次性和可再填充设备的成年人比例相似（4.9%（4.2% 至 5.7%）和 4.6%（4.0% 至 5.3%）） ， 分别）。结论 2013-23 年间，英国成年人长期吸电子烟的流行率大幅上升。这一增长大部分发生在 2021 年之后，恰逢一次性电子烟的普及。一半的长期电子烟使用者现在主要或专门使用一次性设备。增长主要集中在有经常吸烟史的人群中，但也出现在从不经常吸烟的人群中，尤其是年轻人。用于这些分析的数据和代码可在开放科学框架（ ），年龄以乐队形式提供，以保持参与者的匿名性。
