Use of novel tobacco products, such as heated tobacco products, has recently increased as a result of being promoted less harmful alternatives to cigarettes. The impact of the coronavirus disease 2019 (COVID-19) pandemic on tobacco use may differ depending on the type of tobacco.
We longitudinally investigated changes in tobacco use over a 1-year period using internet-based and self-reported questionnaires among Japanese aged 15 to 79 years. The study was conducted from 2019 to 2021, with participants before the COVID-19 pandemic in February 2020 as the pre-pandemic group and participants after that as the pandemic group. Accounting for population bias, we used sampling probability weighting referring to the nationwide data. The association between cessation and the COVID-19 pandemic was evaluated separately for each type of tobacco using logistic regression analysis.
After conducting sampling probability weighting, 1,920 were in the pre-pandemic group and 2,681 were in the pandemic group. More participants in the pandemic group than in the pre-pandemic group achieved cessation after 1 year (13.8% vs 10.2%, P < 0.001). Dual users were more likely to quit during the pandemic than pre-pandemic (adjusted odds ratio [aOR] 2.56, P < 0.001), whereas exclusive novel tobacco users were less likely to quit during the pandemic (aOR 0.66, P = 0.041). Tobacco cessation was more frequently achieved among those who had intended to quit at baseline survey among conventional tobacco users (aOR 1.77, P < 0.001) and dual users (aOR 2.52, P < 0.001); however, this trend was not observed among novel tobacco users (aOR 1.49, P = 0.090).
Conventional and novel tobacco use patterns varied in response to the COVID-19 pandemic.
由于被宣传为危害较小的香烟替代品，加热烟草制品等新型烟草产品的使用近来有所增加。2019年冠状病毒病（COVID-19）大流行对烟草使用的影响可能因烟草类型而异。
我们通过基于互联网的自我报告问卷，对15至79岁的日本人在1年时间内烟草使用情况的变化进行了纵向调查。该研究于2019年至2021年进行，将2020年2月COVID-19大流行之前的参与者作为大流行前组，之后的参与者作为大流行组。考虑到人群偏差，我们使用了参照全国数据的抽样概率加权法。使用逻辑回归分析分别评估每种烟草类型的戒烟与COVID-19大流行之间的关联。
在进行抽样概率加权后，大流行前组有1920人，大流行组有2681人。1年后，大流行组实现戒烟的参与者比大流行前组更多（13.8%对10.2%，P<0.001）。双重使用者在大流行期间比大流行前更有可能戒烟（调整后的优势比[aOR]为2.56，P<0.001），而仅使用新型烟草的使用者在大流行期间戒烟的可能性较小（aOR为0.66，P=0.041）。在常规烟草使用者（aOR为1.77，P<0.001）和双重使用者（aOR为2.52，P<0.001）中，在基线调查时有戒烟意愿的人更频繁地实现了戒烟；然而，在新型烟草使用者中未观察到这种趋势（aOR为1.49，P=0.090）。
常规和新型烟草的使用模式因COVID-19大流行而有所不同。
