A new study suggests that the more teenagers watch television, the more likely they are to develop depression as young adults.

The researchers used a national long-term survey of adolescent health to investigate （调查）the relationship between media use and depression. They based their findings on more than four thousand adolescents who were not depressed when the survey began in 2000.

As part of the survey, the young people were asked how many hours of television or videos they watched daily. They were also asked how often they played computer games and listened to the radio. Media use totaled an average of five and one-half hours a day. More than two hours of that was spent watching TV.

Seven years later, in 2007, more than seven percent of the young people had signs of depression. The average age at that time was twenty-one.

The researchers say they did not find any such relationship with the use of other media such as movies, video games or radio, etc. But the study did find that every extra hour of television meant an eight percent increase in the chances of developing signs of depression. Young men were more likely than young women to develop depression given the same amount of media use.

The study didn’t explore if watching TV causes depression. But one possibility is that it was taking time away from activities that could help prevent depression.

Last December, the journal Social Indicators Research published a study of activities that help lead to happy lives. Sociologists from the University of Maryland found that people who describe themselves as happy spend less time watching television than unhappy people. The study found that happy people are more likely to be socially active to read, to attend religious services and to vote.
