Being plugged into an iPod is a feature of adolescence. A new study suggests that teens wh
o 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 didnt 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.
