Adolescence is a critical period for vaping onset. The purpose of this article was to examine the effect of the early stages of the COVID-19 pandemic period on youth vaping.
We used 3-year linked data from the COMPASS study, including 7585 Canadian (Quebec, Ontario) adolescents from which 1949 completed all three survey waves (pre-COVID-19 [2018, 2019] and online [2020] during the early pandemic period [May-July 2020]) and provided vaping data. Structural equation modeling (SEM) and difference-in-difference (DD) models were used to estimate pre-COVID-19 to initial COVID-19 pandemic period change (2019-2020) in vaping (monthly, weekly, daily) compared with 2018-2019 change to adjust for age-related effects. Models were adjusted for age of entry into the cohort and sociodemographic characteristics.
In the SEM and DD models, the proportion of youth who were monthly and weekly vaping increased from 2018 to 2019 but decreased from 2019 to 2020; daily vaping increased across all waves. However, for all vaping outcomes modeled, the expected increases from the pre-COVID-19 wave (2019) to the initial COVID-19 period wave (2020) were lesser relative to the changes seen across the 2018 to 2019 waves.
The early stages of the COVID-19 pandemic period appear to be associated with a reduction in the proportion of youth who were monthly and weekly vapers in our adjusted longitudinal models. While daily vaping increased over this same period of time, the magnitude of the increase in our adjusted longitudinal models appears attenuated by the early stages of the pandemic.
This large prospective study of youth that included pre-pandemic data is unique in that we were able to identify that the early stages of the COVID-19 pandemic period was associated with a reduction in the proportion of youth who were monthly and weekly vapers in our adjusted longitudinal models. Conversely, the proportion of youth who were daily vaping increased over this same period of time, but the magnitude of the increase appears smaller than expected during the early stages of the pandemic in our adjusted longitudinal models. This study provides novel robust evidence that the patterns of vaping most aligned with onset and progression (i.e., monthly and weekly use) appear attenuated during the initial pandemic period.
青春期是开始吸电子烟的关键时期。本文旨在研究新冠疫情初期对青少年吸电子烟的影响。
我们使用了COMPASS研究的3年关联数据，包括7585名加拿大（魁北克、安大略）青少年，其中1949人完成了所有三轮调查（新冠疫情前[2018年、2019年]以及疫情初期[2020年5月至7月]的线上[2020年]调查）并提供了吸电子烟数据。采用结构方程模型（SEM）和差分模型（DD）来估计与2018 - 2019年变化相比，新冠疫情前到疫情初期（2019 - 2020年）吸电子烟（每月、每周、每日）的变化情况，以调整与年龄相关的影响。模型针对进入队列的年龄和社会人口学特征进行了调整。
在SEM和DD模型中，每月和每周吸电子烟的青少年比例从2018年到2019年有所增加，但从2019年到2020年有所下降；每日吸电子烟的情况在所有调查阶段均有所增加。然而，对于所有建模的吸电子烟结果，相对于2018年到2019年的变化，从新冠疫情前阶段（2019年）到疫情初期阶段（2020年）预期的增加幅度较小。
在我们调整后的纵向模型中，新冠疫情初期似乎与每月和每周吸电子烟的青少年比例下降有关。虽然在此期间每日吸电子烟有所增加，但在我们调整后的纵向模型中，增加幅度在疫情初期似乎有所减弱。
这项纳入了疫情前数据的大型青少年前瞻性研究具有独特性，因为我们能够确定在我们调整后的纵向模型中，新冠疫情初期与每月和每周吸电子烟的青少年比例下降有关。相反，在此期间每日吸电子烟的青少年比例有所增加，但在我们调整后的纵向模型中，增加幅度在疫情初期似乎比预期的要小。这项研究提供了新的有力证据，表明在疫情初期，与开始和进展最相关的吸电子烟模式（即每月和每周使用）似乎有所减弱。
