Most adolescents in the U.S. are exposed to pro-tobacco images and advertising in many locations in their daily lives. Because the pro-tobacco message cannot be completely suppressed, anti-tobacco media campaigns, usually sponsored by governmental agencies, try to counter their effects. In this study, we examined the longitudinal impact of self-reported exposure to pro- and anti-tobacco media exposure on adolescents' susceptibility to smoking, using in-school surveys from a culturally diverse sample. In addition, ethnicity and acculturation were examined as potential moderators. Middle-school students (N=2292) completed self-report questionnaires during the 6th, 7th, and 8th grades. Our results indicate that exposure to both pro-and anti-tobacco advertisements predict changes in smoking susceptibility. Exposure to pro-tobacco media at baseline was associated with an increased risk of smoking susceptibility in year 2 and 3 while exposure to anti-tobacco media at baseline was associated with a decreased risk of smoking susceptibility in year 2 or 3. However, we did not find that pro- and anti-tobacco media interacted in their effects on susceptibility, nor did ethnicity and acculturation moderate the effects of media exposure. Our longitudinal study provides compelling evidence that pro-tobacco media increases susceptibility to smoking over time. More importantly, while there is a potential for anti-tobacco advertisements to limit adolescents' susceptibility to smoking, our results indicate that an anti-tobacco campaign alone is unlikely to negate the large effect of pro-tobacco media exposure. In order to reduce adolescent smoking, stronger measures, such as policy for controlling pro-tobacco advertising and tobacco-supportive media portrayals, will be needed.
