Study links TV and depression

Researchers at the University of Pittsburgh and Harvard Medical School looked at the media habits of 4,142 healthy adolescents and calculated that each additional hour of TV watched per day boosted the odds of becoming depressed by 8%. The results don't prove that TV viewing itself causes depression, but that people with the predilection for later development of depression also happen to have a predilection for watching lots of TV.
