Regulatory Strategies for Preventing and Reducing Nicotine Vaping among Youth: A Systematic Review
A partir d'une revue systématique de la littérature publiée entre 2004 et 2022 (30 articles), cette étude analyse l'efficacité de différentes stratégies réglementaires pour prévenir et réduire le vapotage de nicotine chez les jeunes
Introduction: Many jurisdictions have implemented different regulatory strategies to reduce vaping among youth. The objective of this systematic review is to synthesize the evidence on the effectiveness of different regulatory strategies for preventing and reducing nicotine vaping among youth. Methods: Five electronic databases were searched from January 1st 2004 until July 17th 2022 for primary studies examining state/provincial or national regulations targeting vaping among youth (12-21 years) in high-income countries. The primary outcome was vaping prevalence. Included studies were qualitatively synthesized via systematic review. Results: The systematic review included 30 studies. There was insufficient evidence to recommend age restrictions (n=16), restrictions on location of use (n=1), and mixed/combined regulations (n=3). Flavor bans (n=4), sales licenses (n=2), and taxation (n=2) were generally shown to be associated with decreased rates of youth vaping. Warning labels (n=2) were associated with decreased desire to initiate vaping. Included studies had moderate to serious risks of bias. Discussion: Although several regulatory interventions have been shown to be effective at reducing vaping among youth, evidence is insufficient to recommend a specific type of regulation. Regulatory authorities could implement various regulations targeting the price, accessibility, and desirability (i.e., flavors, packaging) of e-cigarettes.
