Debating Influence of Movies on Kids' Smoking
Aug. 25, 2011— -- The World Health Organization recommends slapping adult ratings on movies with scenes that depict smoking, an approach that some anti-tobacco advocates believe could deter kids from lighting up.
Although WHO guidance is largely symbolic, and most nations have ignored it, supporters of controlling kids' access to these images now say restrictive ratings could influence what movie makers are marketing to kids, according to their policy paper in this week's issue of the journal PLoS Medicine.
In it, Christopher Millett, a public health expert at Imperial College London, and his co-authors from the UC San Francisco Center for Tobacco Control Research and Education, director Dr. Stanton Glantz, and consultant Jonathan Polansky, said that some governments provide "generous subsidies to the U.S. film industry" for movies that indirectly promote tobacco use in youngsters. They would like to turn that around with a policy that relies on economic disincentives, such as making sure that films that include tobacco use are ineligible for public subsidies.
However, others who are just as committed to reducing youngsters' risk of tobacco-associated cancer, heart disease and lung disease, don't think there is enough evidence to demonstrate that controlling who gets into a movie theater can reduce the likelihood kids will become smokers.
Simon Chapman, a public health professor at the University of Sydney in Australia, and Matthew C. Farrelly, a public health policy researcher with RTI International in Research Triangle Park, N.C., offered a four-part argument against the ratings.
First, they said, no one has definitively demonstrated that watching others smoke onscreen leads to more smoking among those in the audience. Furthermore, they said, most of the studies purporting to show that link are muddied by many other factors in kids' lives.
"Movies showing smoking might have a lot more in them that might appeal to youth at risk of smoking than just smoking," they wrote.
As a result, they discounted the strength of published estimates suggesting that 390,000 American youngsters smoke because of what they see onscreen, or that imposing adult ratings on films that include actors smoking would likely prevent 200,000 youngsters from becoming smokers. The figures fail to take into account that kids are drawn to smoking by far more than just what they see at the movies, they said.
