问题     Being plugged into an iPod is a feature of adolescence. A new study suggests that teens who spend too much time listening to music may be at higher risk of depression.
    The study found that teens who reported listening to music more often—【C1】______using other types of media like TV and books—were more likely to have major depressive disorder,【C2】______with teens who listened to music less frequently. With each level increase in music use, teens had an 80% higher risk of depression, the study found. The study didn’t measure【C3】______listening times, but based on previous data, the study authors【C4】______that teens in the highest-use group were likely listening to music【C5】______at least four or five hours a day.
    At this【C6】______it is not clear whether depressed people begin to listen to more music to【C7】______or whether listening to large【C8】______of music can lead to depression, or both.【C9】______researchers found that reading books had the opposite【C10】______: with time spent in reading increasing, teens’ risk of depression【C11】______50%. This is worth emphasizing because overall in the U.S., reading books is decreasing,【C12】______nearly all other forms of media use are increasing.
    For the study, the researchers【C13】______106 participants aged 7 to 17 for two months; 46 participants had been previously【C14】______with depression. Throughout the course of the study, researchers made【C15】______weekend phone calls to the teens in order to determine, in real time, what forms of media they were using,【C16】______television, music, video games, Internet, magazines and books. On average, teens were most likely to be watching a movie or TV when researchers called (26% of the time). Teens reported listening to music 9% of the time, followed by Internet use and video gaming (6% each) and,【C17】______, reading printed media (0.2%).
    Of all the media reported, only music showed【C18】______associations with increased depression risk,【C19】______researchers had control of【C20】______like age, sex and race.
