语言朋友(3) WASHINGTON(April 7)－Teenagers with a bedroom TV tend to have poorer diet and exercise habits and lower grades in school than those without one，US researchers said on Monday. While many studies have examined TV viewing habits of young people，researchers at the University of Minnesota School of Public Health said little had been known about the consequences(后果)in particular for older teens of having a bedroom TV. They questioned 781 teens，aged 15 to 18，in the Minneapolis area.Of them，62 percent had a television in their bedrooms. Not surprisingly，those with a bedroom TV were more likely to watch it a lot，clocking four to five more hours in front of a television per week，the researchers said.The teens with a bedroom TV were classified(分类)as heavy TV watchers－at least five hours a day－compared to those without one. Girls with a bedroom TV got less exercise－1.8 hours per week compared to 2.5 hours for girls without a TV.They also ate fewer vegetables，drank more sweetened drinks and ate meals with their family less often. Boys with a bedroom TV had a lower grade point average than boys without one，as well as ate less fruits and had fewer family meals. “It really clearly points out that there's some merit to not allowing your child to have a TV in the bedroom，”said Daheia BarrAnderson，one of the researchers. |
