Abstract

INTRODUCTION

E-cigarette and cigarette use may have changed during the COVID-19 pandemic, however, there is no consensus in existing literature, and current Canadian studies have not used representative samples. Thus, there is a need for robust national estimates.

OBJECTIVE AND METHODS

The primary objective was to describe the 30-day period prevalence of smoking and vaping before and during the COVID-19 pandemic in Canada. This study analyzed three years of the cross-sectional Canadian Tobacco and Nicotine Survey: 2019 (pre-pandemic), 2020 (9 months into the pandemic) and 2021 (21 months into pandemic).

RESULTS

Thirty-day period prevalence of vaping over the 2019, 2020, and 2021 study periods were 4.8 (95%CI: 4.2-5.3), 4.6% (95%CI: 4.1-5.2), and 5.2% (95%CI: 4.7-5.7), respectively. The 30-day period prevalence of smoking over the 2019, 2020, and 2021 study periods were 11.9% (95%CI: 10.9-12.7), 10.3% (95%CI: 9.4-11.2), and 10.3% (95%CI: 9.4-11.1), respectively. Notably, estimates of smoking for females decreased considerably from 2019 (11.0%; 95%CI: 9.9--12.2%) to 2020 (8.6%; 95%CI: 7.5-9.7). Estimates of vaping in those aged 20-24 increased substantially from 2020 (13.0%; 95%CI: 10.9-15.1) to 2021 (17.2%; 95%CI: 15.4-18.9).

CONCLUSIONS

Changes to smoking and vaping were restricted to subsets within the population. In those aged 20-24, there was a modest increase in vaping from 2020 to 2021. In females, there was a decrease in smoking from 2019 to 2020, which persisted in 2021.

摘要

介绍

在 COVID-19 大流行期间,电子烟和香烟的使用情况可能发生了变化,但现有文献中尚无共识,而且加拿大目前的研究并未使用具有代表性的样本。因此,需要进行强有力的全国性估计。

目的和方法

主要目的是描述加拿大在 COVID-19 大流行之前和期间的 30 天吸烟和蒸气吸烟流行率。本研究分析了加拿大烟草和尼古丁调查的三年横断面数据:2019 年(大流行前)、2020 年(大流行 9 个月)和 2021 年(大流行 21 个月)。

结果

2019 年、2020 年和 2021 年研究期间,30 天吸烟流行率分别为 4.8%(95%CI:4.2-5.3)、4.6%(95%CI:4.1-5.2)和 5.2%(95%CI:4.7-5.7)。2019 年、2020 年和 2021 年研究期间,30 天蒸气吸烟流行率分别为 4.8%(95%CI:4.2-5.3)、4.6%(95%CI:4.1-5.2)和 5.2%(95%CI:4.7-5.7)。2019 年、2020 年和 2021 年研究期间,30 天吸烟流行率分别为 11.9%(95%CI:10.9-12.7)、10.3%(95%CI:9.4-11.2)和 10.3%(95%CI:9.4-11.1)。值得注意的是,女性的吸烟率从 2019 年(11.0%;95%CI:9.9-12.2%)显著下降至 2020 年(8.6%;95%CI:7.5-9.7%)。20-24 岁人群中,2020 年(13.0%;95%CI:10.9-15.1)到 2021 年(17.2%;95%CI:15.4-18.9)蒸气吸烟的估计值大幅增加。

结论

吸烟和蒸气吸烟的变化仅限于人群中的亚组。在 20-24 岁人群中,2020 年至 2021 年蒸气吸烟略有增加。在女性中,2019 年至 2020 年吸烟率下降,2021 年仍持续下降。
