To estimate recent trends in the prevalence of disposable e-cigarette vaping in Great Britain, overall and across ages, and to measure these trends in the context of changes in smoking and vaping prevalence.
The Smoking Toolkit Study, a monthly representative cross-sectional survey.
Great Britain.
A total of 36 876 adults (≥ 18 years) completed telephone interviews between January 2021 and April 2022.
Current e-cigarette vapers were asked which type of device they mainly use. We estimated age-specific monthly time trends in the prevalence of current disposable e-cigarette use among vapers and inhaled nicotine use (vaping/smoking), smoking and vaping among adults.
From January 2021 to April 2022, there was an 18-fold increase in the percentage of vapers who used disposables, rising from 1.2 to 22.2% [prevalence ratio (PR) = 18.0; 95% compatibility interval (CI) = 9.18-49.0]. Growth in disposable e-cigarette vaping was most pronounced in younger adults (interaction P-value = 0.013): for example, the percentage of 18-year-old vapers using disposables rose from 0.4 to 54.8% (PR = 129; 95% CI = 28.5-4520), while it rose from 2.1 to 10.0% (PR = 4.73; 95% CI = 2.06-23.6) among 45-year-old vapers. However, the overall percentage of people currently using any inhaled nicotine remained stable over time both among all adults (20.0 versus 21.2%; PR = 1.06; 95% CI = 0.92-1.22) and among 18-year-olds (30.2 versus 29.7%; PR = 0.99; 95% CI = 0.80-1.22). In 18-year-olds, vaping prevalence grew (11.3 versus 17.7%; PR = 1.57; 95% CI = 1.12-2.29), and there was imprecise evidence for a decline in smoking (24.5 versus 19.5%; PR = 0.80; 95% CI = 0.63-1.04). In 45-year-olds, there was relatively little change in vaping (PR = 1.08; 95% CI = 0.88-1.33) or smoking prevalence (PR = 1.01; 95% CI = 0.88-1.16).
Use of disposable e-cigarettes in Great Britain grew rapidly between 2021 and 2022, especially among younger adults, but the overall prevalence of inhaled nicotine use was stable over time. Most young adult vapers in Great Britain now use disposable products.
估计英国最近一次性电子烟吸食流行率的趋势，包括总体趋势和各年龄段的趋势，并在吸烟和电子烟流行率变化的背景下衡量这些趋势。
吸烟工具包研究，每月进行一次代表性横断面调查。
英国。
共有 36876 名成年人（≥18 岁）在 2021 年 1 月至 2022 年 4 月期间完成了电话访谈。
询问当前电子烟使用者他们主要使用哪种设备。我们估计了在吸烟者和尼古丁吸入者（电子烟/吸烟）中，当前一次性电子烟使用的年龄特异性月度时间趋势，以及成年人中的吸烟和电子烟使用情况。
从 2021 年 1 月到 2022 年 4 月，使用一次性电子烟的电子烟使用者比例增加了 18 倍，从 1.2%上升到 22.2%（患病率比（PR）= 18.0；95%置信区间（CI）= 9.18-49.0）。在年轻人中，一次性电子烟的使用增长最为显著（交互 P 值= 0.013）：例如，18 岁电子烟使用者中使用一次性电子烟的比例从 0.4%上升到 54.8%（PR = 129；95%CI = 28.5-4520），而 45 岁电子烟使用者中这一比例从 2.1%上升到 10.0%（PR = 4.73；95%CI = 2.06-23.6）。然而，在所有成年人（20.0%对 21.2%；PR = 1.06；95%CI = 0.92-1.22）和 18 岁成年人（30.2%对 29.7%；PR = 0.99；95%CI = 0.80-1.22）中，目前使用任何吸入尼古丁的总人数在整个时间内保持稳定。在 18 岁的人中，电子烟的使用率上升（11.3%对 17.7%；PR = 1.57；95%CI = 1.12-2.29），而吸烟的证据则不太准确（24.5%对 19.5%；PR = 0.80；95%CI = 0.63-1.04）。在 45 岁的人中，电子烟（PR = 1.08；95%CI = 0.88-1.33）或吸烟（PR = 1.01；95%CI = 0.88-1.16）的流行率变化相对较小。
2021 年至 2022 年期间，英国一次性电子烟的使用迅速增加，尤其是在年轻人中，但总体吸入尼古丁使用率保持稳定。现在，英国大多数年轻成年电子烟使用者都在使用一次性产品。
