Harm Perceptions of Alternative Tobacco Products among US Adolescents.

ABSTRACT

OBJECTIVES: In this study, we identified groups of adolescents who share similar awareness and perceptions of harm regarding e-cigarettes, cigars, hookah, and smokeless tobacco. METHODS: We used latent class analyses (LCA) with the data from Wave 1 (2013-14) of the Population Assessment of Tobacco and Health youth and parent survey (PATH; N = 13,650) to address the research goal. Multinomial logistic regression analysis assessed the associations between identified classes with demographic characteristics and tobacco use. RESULTS: LCA identified 5 classes (1) perceived harm across all alternative tobacco products (36.6%); (2) perceived harm for e-cigarettes and smokeless tobacco but never heard of cigars and hookah (48.2%); (3) never heard of alternative tobacco products (8.6%); (4) mix of no harm and harm across alternative tobacco products (5.2%); and (5) "don't know" the harm across alternative tobacco products (1.4%). Relative to the class who perceived harm across all alternative tobacco products, classes of adolescents who were unaware of the products or did not know the harms were more likely to be non-white, younger, have lower parental education, and less likely to have tried an alternative tobacco product. CONCLUSIONS: Tobacco prevention should target vulnerable youth, such as adolescents who are non-white, young, and have low parental education.
