The association between vaping and subsequent initiation of cigarette smoking in young Australians from age 12 to 17 years: a retrospective cohort analysis using cross-sectional recall data from 5114 adolescents
Objective
The objective of this study was to estimate the association between vaping and subsequent initiation of smoking among Australian adolescents and explore the impact of design and analytical methods in previous studies.
Methods
We conducted a retrospective cohort analysis of cross-sectional data from 5114 Australian adolescents aged 14–17 recalling information on smoking and vaping initiation from age 12 to 17. The outcome was smoking initiation, analysed with negative-binomial regression to estimate incidence rate ratios (IRRs) for vape status (ever-vaped vs never-vaped) as a time-varying exposure. We also re-analysed using the methods of previous studies not accounting for the time-varying nature of e-cigarette exposure.
Results
Participants (n=5114) were retrospectively followed for 20478 person-years. After adjusting for socio-demographic variables and proxy measures of common liabilities for vaping and smoking, the rate of smoking initiation for those who ever-vaped was nearly 5 times that of those who never-vaped (IRR=4.9; 95% confidence interval: [3.9, 6.0], p<0.001), with IRRs considerably higher at younger ages. Not accounting for the time-varying nature of e-cigarette exposure in re-analysis attenuated the estimated IRR by 44%.
Conclusions
Controlled analyses indicate that vaping markedly increases the risk of subsequent smoking initiation among Australian adolescents from age 12 to 17, with those aged 12, 13, and 14 bearing an alarmingly disproportionate burden of the elevated risk. Additionally, the relative risk of future smoking due to vaping may have been underestimated in other studies due to methodological differences.
Implications for public health
Our findings highlight the need for public health interventions and strict e-cigarette access laws.
期刊介绍:
The Australian and New Zealand Journal of Public Health (ANZJPH) is concerned with public health issues. The research reported includes formal epidemiological inquiries into the correlates and causes of diseases and health-related behaviour, analyses of public policy affecting health and disease, and detailed studies of the cultures and social structures within which health and illness exist. The Journal is multidisciplinary and aims to publish methodologically sound research from any of the academic disciplines that constitute public health.
