[BDSP. Notice produite par INIST-CNRS R0x9aC4w. Diffusion soumise à autorisation]. Context Children's exposure to violence, alcohol, tobacco and other substances, and sexual messages in the media are a source of public health concern ; however, content in video games commonly played by children has not been quantified. Objectives To quantify and characterize the depiction of violence, alcohol, tobacco and other substances, and sex in video games rated E (for "Everyone"), analogous to the G rating of films, which suggests suitability for all audiences. Design We created a database of all existing E-rated video games available for rent or sale in the United States by April 1,2001, to identify the distribution of games by genre and to characterize the distribution of content descriptors associated with these games. We played and assessed the content of a convenience sample of 55 E-rated video games released for major home video game consoles between 1985 and 2000. Main Outcome Measures Game genre ; duration of violence ; number of fatalities ; types of weapons used ; whether injuring characters or destroying objects is rewarded or is required to advance in the game ; depiction of alcohol, tobacco and other substances ; and sexual content. Results Based on analysis of the 672 current E-rated video games played on home consoles, 77% were in sports, racing, or action genres and 57% did not receive any content descriptors. We found that 35 of the 55 games we played (64%) involved intentional violence for an average of 30.7% of game play (range, 1.5% - 91.2%), and we noted significant differences in the amount of violence among game genres. Injuring characters was rewarded or required for advancement in 33 games (60%). The presence of any content descriptor for violence (n=23 games) was significantly correlated with the presence of intentional violence in the game (at a 5% significance level based on a 2-sided Wilcoxon rank-sum test, t53=2.59). Notably, 14 of 32 games (44%) that did not
