Trends in exposure to pro-tobacco advertisements over the Internet, in newspapers/magazines, and at retail stores among U.S. middle and high school students, 2000–2012
Menée à partir des données d'une enquête nationale américaine réalisée sur la période 2000-2012 (7 campagnes, 183 151 réponses au total), cette étude analyse l'évolution de la prévalence du tabagisme chez les lycéens et les étudiants en fonction de leur niveau d'exposition aux publicités pro-tabac de 3 types de médias (internet, journaux et magazines, débits de tabac)
Background : Most tobacco use begins during youth. Thus, this study assessed the prevalence, trends, and correlates of pro-tobacco advertising among United States students in grades 6–12 during 2000–2012. Methods : Data from the 2000–2012 National Youth Tobacco Survey were analyzed to assess self-reported exposure to pro-tobacco advertisements through three media: over the Internet, in newspapers/magazines, and at retail stores. Trends during 2000–2012 were assessed in a binary logistic regression model (P < 0.05). Results : Among all middle and high school students, the overall prevalence of exposure to Internet pro-tobacco advertisements increased from 22.3% to 43.0% during 2000–2012 (P < 0.001 for linear trend). During the same period, declines were observed in the overall prevalence of exposure to pro-tobacco advertisements in newspapers/magazines (65.0% to 36.9%) and at retail stores (87.8% to 76.2%) (P < 0.001 for all linear trends). Conclusion : Exposure to pro-tobacco advertisements over the Internet increased significantly during 2000–2012 among United States middle and high school students, while a decline in exposure to advertisements in newspapers or magazines, and at retail stores occurred during the same period. However, over two-thirds of students still report retail store exposure to pro-tobacco advertisements. Enhanced and sustained efforts would be beneficial to reduce even more exposure to all forms of pro-tobacco advertisements among youths.
