Objective:

To examine and compare overall prevalence and time trends in tobacco and alcohol portrayals and brand appearances in youth-rated US and nationally-produced films that were the most successful in Argentina and Mexico from 2004-2012.

Materials and methods:

Top-grossing nationally produced films from Argentina (n=73), Mexico (n=85) and the US (n=643) were content analyzed. Logistic regression was used to determine differences between Mexican, Argentine and US produced films. Linear regression models assessed significant cross-country differences in the mean number of tobacco and alcohol seconds.

Results:

Films from Mexico and Argentina were more likely than US films to contain tobacco, (OR=4.2; p<0.001) and (OR=7.2; p<0.001). Alcohol was present in 93% of Argentine, 83% in Mexican and 83% US films.

Conclusions:

Smoking and alcohol were highly prevalent in nationally produced films. They may have a significant impact and should be targeted by policies to reduce youth exposure to portrayals of risk behaviors.
