Bottom Line: Improved school performance, better sleep and behaviour in children has been associated with parental monitoring of the time children spend watching television, playing video games and being online.
Author: Douglas A. Gentile, Ph.D., of Iowa State University, Ames, and colleagues.
Background: Previous research suggests high levels of screen time are associated with less sleep, attention problems and lower academic progress.
How the Study Was Conducted: The study included self-reported data from 1,323 school children (in the third through fifth grades) from two communities in Iowa and Minnesota, along with data about the students provided by primary caregivers and teachers. The data were collected as part of an obesity prevention program.
Results: Study results suggest that increased monitoring by parents reduced children's total screen time (TST) which results in children getting more sleep, doing better in school and having less aggressive behavior. The results suggest more sleep is associated with a lower body mass index (BMI). More parental monitoring also resulted in less exposure to violence on television and in video games, which was associated with increased positive behavior and decreased aggressive behavior.
Discussion: "Pediatricians, family practitioners, nurses and other health care professionals who encourage parents to be more involved in their children's media may be much more effective at improving a wide range of healthy behaviors than they realize."
