Abstract
OBJECTIVE:
Studies of US adolescents have linked exposure to movie smoking with smoking behavior. It is unclear whether European adolescents are also responsive to movie tobacco imagery.
METHODS:
A longitudinal study was conducted to assess exposure to movie smoking in 2711 German never-smokers (aged 10 to 16 years). Movie smoking exposure was estimated by asking adolescents if they had seen movies from a list of 50 movie titles, randomly selected for each adolescent from 398 internationally distributed movies released between 1994 and 2004 that became box-office hits in Germany. These films were reviewed for smoking content. Adolescents were resurveyed 12 to 13 months later to determine smoking status, and results were compared with a similarly designed survey of 2603 white US adolescents. We hypothesized replication of the main effect of the exposure on trying smoking, and an interaction, with a significantly larger response among adolescents whose parents did not smoke.
RESULTS:
The 398 internationally distributed movies represented 80% of the German box-office hits within this time frame, with the majority (388) produced and/or distributed internationally by US companies. Smoking was present in 74% of the movies. Overall, 503 (19%) of the students tried smoking during the follow-up period. The incidence of trying smoking was associated with increased exposure to movie smoking. The form of the dose-response was similar to the US sample, with the strongest response to movies seen in the lower 2 quartiles of exposure. After controlling for baseline covariates, exposure to movie smoking remained a significant predictor of trying smoking in German adolescents, and the effect was significantly stronger in adolescents whose parents did not smoke.
CONCLUSIONS:
Smoking in internationally distributed US movies predicts trying smoking among German adolescents, closely replicating findings from a longitudinal study of white US adolescents. Smoking in these movies could have important worldwide public health implications.
