A Risk-Continuum Categorization of Product Use among U.S. Youth Tobacco Users
Menée sur un échantillon représentatif des jeunes Américains incluant 3 202 utilisateurs de tabac âgés de 9 à 17 ans, cette étude analyse, en fonction de critères socio-démographiques, la prévalence de 5 modèles de tabagisme (cigarettes, produits tabagiques non combustibles, utilisation conjointe de deux produits tabagiques, ...)
Introduction : To examine prevalence and correlates of five mutually exclusive tobacco-use patterns among U.S. youth tobacco users. Methods : A nationally representative sample of tobacco users (N = 3,202, 9 – 17 years) was classified into five product-use patterns. Weighted multinominal and multivariate logistic regression models were used to examine prevalence of product-use pattern by gender, race and ethnicity, and grade level; and associations between product-use pattern and perceived accessibility of tobacco products, exposure and receptivity to pro-tobacco marketing, social benefits of smoking, and tobacco-associated risks. Results : Dual use (i.e., use of two product categories) was the most prevalent pattern (30.5%), followed by non-cigarette combustible only (26.7%), polytobacco (i.e., use of three product categories) (17.5%), cigarette only (14.9%), and non-combustible only (10.4%) use. Product-use pattern differed by gender, race and ethnicity. Compared to cigarette only users, dual and polytobacco users were more likely to be exposed to and be receptive to pro-tobacco marketing, and were less likely to acknowledge tobacco-use related risks (ps < 0.05). Conclusions : Curbing tobacco use warrants research on users of >1 tobacco-product categories according to the risk-continuum categorization.
