"The more movie scenes of smoking people watch, the more likely you will want to experiment with smoking", researchers at The University of Texas M. D. Anderson Cancer Center and Dartmouth College report in the December issue of Cancer Epidemiology, Biomarkers and Prevention.
The three-year prospective study of 1,286 american teens showed the percentage of new experimenters increased from about 5 percent among those with little or no exposure to nearly 30 percent for those who saw up to 600 smoking scenes. The effect was dose-dependent, with experimentation linearly correlated with movie exposure.
“Parents need to limit their adolescents’ access to R-rated movies, which research has shown have the most depictions of smoking,” said lead author Anna Wilkinson, Ph.D., assistant professor in M. D. Anderson’s Department of Epidemiology in the Division of Cancer Prevention and Population Sciences.
