Assessing cigarette packaging and labelling policy effects on early adolescents: results from a discrete choice experiment

Abstract

Introduction: Cigarette packaging is a primary channel for tobacco advertising, particularly in countries where traditional channels are restricted. The current study evaluated the independent and interactive effects of cigarette packaging and health warning label (HWL) characteristics on perceived appeal of cigarette brands for early adolescents in Mexico.

Methods: A discrete choice experiment (DCE) was conducted with early adolescents, aged 12-14 years (n4251). The DCE involved a 325 design with six attributes: brand (Marlboro, Pall Mall, Camel), tobacco flavour (regular, menthol), flavour capsule (none, 1 or 2 capsules), presence of descriptive terms, branding (vs plain packaging), HWL size (30, 75) and HWL content (emphysema vs mouth cancer). Participants viewed eight sets of three cigarette packs and selected a pack in each set that: (1) is mostleast attractive, (2) they are mostleast interested in trying or (3) is mostleast harmful, with a no difference option.

Results: Participants perceived packs as less attractive, less interesting to try and more harmful if they had plain packaging or had larger HWLs, with the effect being most pronounced when plain packaging is combined with larger HWLs. For attractiveness, plain packaging had the biggest influence on choice (43), followed by HWL size (19). Interest in trying was most influenced by brand name (34), followed by plain packaging (29). Perceived harm was most influenced by brand name (30), followed by HWL size (29).

Conclusion: Increasing the size of HWLs and implementing plain packaging appear to reduce the appeal of cigarettes to early adolescents. Countries should adopt these policies to minimise the impact of tobacco marketing.
