Youth spend an average of >7 hours/day using media, and the vast majority of them have access to a bedroom television, computer, the Internet, a video-game console, and a cell phone. In this article we review the most recent research on the effects of media on the health and well-being of children and adolescents. Studies have shown that media can provide information about safe health practices and can foster social connectedness. However, recent evidence raises concerns about media's effects on aggression, sexual behavior, substance use, disordered eating, and academic difficulties. We provide recommendations for parents, practitioners, the media, and policy makers, among others, for ways to increase the benefits and reduce the harm that media can have for the developing child and for adolescents.

Influence: Social learning theory - observing and imitation, "scripts", "superpeer." Reported exposure to violence leading to acceptance of violence as means of problem solving, desensitization, increase in aggression, and decrease in altruism. Relationship between media violence and real-life aggression nearly as strong as relationship between cigarrette and cancer. Epoxure to sexually explicit material or sexual mainstream content predicted perpetration of sexual harrassment (explicit material), more permissive sexual norms, early sexual experience, greater risk of unplanned teen pregnancy, and STD. 13-19 yo 20% sent and 48% received sexual messages. Obesity and eating disorders (Fiji study). ADHD and language delay. Heavy tv viewing assoc with hld, htn, asthma, sleep d/o, mood d/o, psychological distress, and depression.
Recs: 1. 1-2 hr per day total screen time. 2. avoid in children < 2 yo. 3. no media in bedrooms. 4. co-view with children and discuss content. Strongest predictor of children's heavy media use is parent heavy media use.
