The impact of anti-tobacco industry prevention messages in tobacco producing regions:: evidence from the US truth® campaign

Background: Adolescents who live in tobacco producing regions may not respond favourably to anti-industry ads. Objective: To examine whether state level involvement in tobacco production appears to limit the effectiveness of anti-industry ads to prevent tobacco use among adolescents in the USA. Design: Time trend analyses were done using repeated cross sectional data from six waves of the Legacy Media Tracking Survey, which were collected between 1999 and 2003. Setting and participants: 28 307 adolescents, ages 12 - 17 years, were classified as living in: tobacco producing states (TPS) ( n = 1929); non-tobacco producing states (non-TPS) with low tobacco control funding comparable to TPS ( n = 5323); non-TPS with relatively high funding ( n = 15 076); and non-TPS with established anti-industry ad campaigns ( n = 5979). Main outcome measures: Reactions to anti-industry ads; strength of anti-industry attitudes/beliefs; changes in anti-industry attitudes/beliefs over time. Results: Ad reactions did not differ by state type. Multivariate adjusted time trend analyses indicated significant, comparable increases in anti-industry attitudes/beliefs since the onset of the truth(r) campaign, in both TPS and non-TPS. Mediation analyses indicated that these increases were due, in part, to campaign exposure. Conclusions: Adolescents who live in tobacco producing regions appear to be as responsive to anti-industry ads as their counterparts in non-tobacco producing regions. This study provides further evidence for the effectiveness of such ads.
