Cigarette and e-cigarette use are prevalent among Canadian adolescents. Evidence shows psychiatric comorbidity with adolescent cigarette smoking, but little is known about psychological well-being among dual users of e-cigarettes and cigarettes. This study examined the association between dual-use status and psychological well-being among high school students.
We used the 2016-2017 Canadian Student Tobacco, Alcohol, and Drugs Survey. Scales of psychological well-being (relatedness, autonomy, competency, prosocial behavior, and social responsiveness) were derived from self-reported data. Dual-use status was categorized into non-users, cigarette-only smokers, e-cigarette-only users, and four types of dual-users. Multivariable linear regression models examined the association between dual-use and psychological well-being.
Among the participants, 6.3% were current dual-users, 4.1% were cigarette-only smokers, 12.6% were e-cigarette-only users, and 77.0% were non-users. Compared to non-users, relatedness and social responsiveness were lower for all users. When compared to e-cigarette users, most other users had lower relatedness (high-frequency dual-users [β=-6.05], high-frequency cigarette dual-users [β=-2.27], high-frequency e-cigarette dual-users: [β=-1.32], low-frequency dual-users [β=-1.91], and cigarette-only smokers [β=-1.66]) and social responsiveness. High-frequency dual-users had lower scores for relatedness and social responsiveness, while high-frequency cigarette dual-users had higher autonomy, compared to low-frequency dual-users.
Dual-users had poorer psychological well-being, which differed among dual-user sub-groups. This study highlights an opportunity for specialized programs to promote psychological well-being and reduce tobacco product use among adolescents.
The study is based on respondent self-report, and the use of cross-sectional data precludes us from determining the temporal order between dual-use and psychological well-being.
香烟和电子烟在加拿大青少年中很普遍。有证据表明，青少年吸烟与精神共病有关，但对于同时使用电子烟和香烟的双重使用者的心理健康状况知之甚少。本研究调查了高中生中双重使用状态与心理健康之间的关系。
我们使用了 2016-2017 年加拿大学生烟草、酒精和毒品调查。心理健康量表（相关性、自主性、能力、亲社会行为和社会反应）是根据自我报告的数据得出的。双重使用状态分为非使用者、仅吸烟的香烟使用者、仅电子烟使用者和四种类型的双重使用者。多变量线性回归模型调查了双重使用与心理健康之间的关系。
在参与者中，有 6.3%的人是当前的双重使用者，4.1%的人是仅吸烟的香烟使用者，12.6%的人是仅电子烟使用者，77.0%的人是非使用者。与非使用者相比，所有使用者的相关性和社会反应性都较低。与电子烟使用者相比，大多数其他使用者的相关性较低（高频双重使用者[β=-6.05]，高频香烟双重使用者[β=-2.27]，高频电子烟双重使用者[β=-1.32]，低频双重使用者[β=-1.91]，以及仅吸烟的香烟使用者[β=-1.66]）和社会反应性。与低频双重使用者相比，高频双重使用者的相关性和社会反应性得分较低，而高频香烟双重使用者的自主性得分较高。
双重使用者的心理健康状况较差，不同的双重使用者亚组之间存在差异。本研究强调了有机会为青少年提供专门的计划，以促进心理健康和减少烟草制品的使用。
该研究基于受访者的自我报告，且横断面数据的使用使我们无法确定双重使用和心理健康之间的时间顺序。
