Youth preferences for roll-your-own versus factory-made cigarettes: Trends and associations in repeated national surveys (2006-13) and implications for policy
Menée en Nouvelle-Zélande à partir des données d'une enquête annuelle nationale réalisée entre 2006 et 2013 auprès de plusieurs milliers de fumeurs adolescents (âge : de 14 à 15 ans), cette étude analyse l'évolution de la proportion d'adolescents roulant leurs propres cigarettes, identifie les facteurs associés, puis analyse les implications en matière de politique de lutte contre le tabagisme
Introduction : We investigated trends in roll-your-own (RYO) and factory-made (FM) cigarette use over time among youth in New Zealand (NZ), a high RYO use country. We also explored factors associated with RYO use. Methods : We analysed data from an annual survey of NZ students (14-15yo) from 2006-2013. Smokers were asked whether they usually smoked RYO or FM cigarettes, and provided details of their source of supply. We estimated prevalences and developed a binary logistic regression model to explore determinants of RYO use. Results : Between 6,663 (2006) and 3,143 (2013) current smokers responded. Each year, around 80% reported usually smoking RYO or FM cigarettes. The proportion reporting usual RYO use was 45% [95% CI ±3%] in 2006, reducing to 40% [95% CI ±3%] in 2013 [trend test: p<0.001]. By contrast, the proportions reporting usual FM use increased slightly over time from 36% [95% CI ±3%] in 2006 to 38% [95% CI ±3%] in 2013 [trend test: p<0.001]. Usual RYO use was more common amongst regular smokers, those who initiated smoking younger, who belonged to low or medium SES groups, and whose friends and family both smoked. Conclusions : Roll-your-own use is very high among NZ youth who smoke. Preference for RYO cigarettes amongst longer-term, regular smokers suggests RYO tobacco supports and maintains youth smoking. There was some initial evidence that a 2010 differential tax increase on RYO tobacco was associated with a shift away from usual RYO use amongst those who sourced tobacco from caregivers or friends. Additional measures such as further differential excise tax increases appear warranted
