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.

这里是VOA特别英语健康报道。
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。
