Children, adolescents, and the media in the 21st century.

American children and adolescents spend an average of 3-5 hours per day with a variety of media, including television, radio, videos, videogames, and the Internet. Considerable research exists to document concerns about media violence, the impact of media on teen sexual attitudes and behavior, the relationship between alcohol and cigarette advertising and adolescent drug use, and the impact of R-rated films on attitudes about sexual violence. Very little research exists concerning adolescents' use of the Internet and the potential behavioral impact, but many parents and professionals are concerned. Solutions include: better programming, stricter regulation by parents, media education at home and in schools, and greater advocacy on the part of health professionals.
