A new study suggests that the more teenagers watch television, the more likely they are to develop depression as young adults. But the extent to which TV may or may not be to blame is a question that the study leaves unanswered. The researchers used a national long-term survey of adolescent health to investigate 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 nineteen ninety-five.
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 two thousand two, more than seven percent of the young people had signs of depression. The average age at that time was twenty-one.

一项新研究发现青少年越沉迷于电视，会有更大几率在他们成年是得抑郁症。但是哪种电视应该或不应该受到谴责没有这个研究领域内给出答案。研究人员用一个针对青少年的国家长期调查来研究媒体使用和抑郁之间的关系。他们的研究以超过4，000的青少年为对象，在1995年这项调查开始时这些人都没有抑郁。
调查的一部分，这些年轻人被问：他们一天看多少小时电视或者视频。他们也被问他们玩电脑游戏和听广播的频率。
媒体使用总计的平均数是5.5小时每天。两个多小时看电视，7年过后，在2002年，有7％的年轻人显示出抑郁。这时他们的平均年龄是21岁。

Brian Primack at the University of Pittsburgh medical school was the lead author of the new study. He says every extra hour of television meant an eight percent increase in the chances of developing signs of depression.
The researchers say they did not find any such relationship with the use of other media such as movies, video games or radio. But the study did find that young men were more likely than young women to develop depression given the same amount of media use.
Doctor Primack says the study did not explore if watching TV causes depression. But one possibility, he says, is that it may take time away from activities that could help prevent depression, like sports and socializing. It might also interfere with sleep, he says, and that could have an influence.
The study was just published in the Archives of General Psychiatry.
In 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, attend religious services and to vote.

Brian Primack 在匹兹堡大学医学院是这项研究的主导人员。他说每增加一个小时看电视意味着多8％的机会发展成为抑郁症。研究人员说他们没有发现使用其他媒体象电影，视频游戏或广播也会有这种联系。但是研究确实发现了年轻男子比年轻女子更可能发展成抑郁症，如果他们都使用一样数量的媒体。
Primack医生说研究没有探索是否看电视导致抑郁。但有一种可能，他说，他会占用阻止抑郁活动的时间，象体育和社交，这也可能妨碍睡觉，他说，那可能会有一些影响。
这项研究发表在Archives of General Psychiatry.
在12月，社会指数调查杂志发表了一项研究是：运动帮助产生愉悦的生活。来自马里兰大学的社会学家发现幸福的人们这样描述自己：他们看电视的时间要比那些不幸福的人少。研究发现高兴的人们更熄火参加社会活动，读书，参加宗教服务，去投票。
