Il lavoro citato ha studiato lo sviluppo di problemi dell'apprendimento a scuola e l'uso eccessivo di televisione negli adolescenti. Ne sono stati studiati circa 700, seguiti dai 14 ai 22 anni. Le conclusioni sono per una maggiore difficoltà nella resa scolastica in quei soggetti che superavano le tre ore al giorno di televisione. L'AAP in un precedente lavoro consigliava di non superare le due ore al giorno.

Study Links TV Viewing with Learning Difficulties in Adolescence
Adolescents who watch a lot of television may be at increased risk for attention and learning problems and failure to go beyond high school, a study finds.
The prospective study, published in the Archives of Pediatrics & Adolescent Medicine, used a community-based sample of some 700 mothers and their children. The offspring were interviewed at mean ages of 14, 16, and 22. After controlling for family characteristics and earlier cognitive difficulties, researchers found that frequent TV viewing at age 14 was associated with indicators of subsequent attention and learning difficulties and academic failure. Youngsters who watched 3 or more hours a day were twice as likely to fail to get postsecondary education as those who watched less than an hour.
The authors said healthcare professionals should encourage youths to spend less than 3 hours a day watching TV. The American Academy of Pediatrics recommends no more than 1 to 2 hours a day of television.
