Association Between Television, Movie, and Video Game Exposure and School Performance

ASSOCIATION BETWEEN TELEVISION, MOVIE AND VIDEO GAME EXPOSURE AND SCHOOL PERFORMANCE
[SOURCE: Pediatrics, AUTHOR: Iman Sharif and James D. Sargent]
A population-based cross-sectional survey of middle school students (grades 5­8) in the Northeastern United States finds that the odds of poorer school performance increased with increasing weekday television screen time and cable movie channel availability and decreased with parental restriction of television content restriction. As compared with children whose parents never allowed them to watch R-rated movies, children who watched R-rated movies once in a while, sometimes, or all of the time had significantly increased cumulative odds of poorer school performance. Weekend screen time and video game use were not associated with school performance.
