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 in particular for older adolescents of having a bedroom TV.
They questioned 781 adolescents, ages 15 to 18, in the Minneapolis area in 2003 and 2004. Of them, 62 percent reported having a television in their bedroom.
Not surprisingly, those with a bedroom TV were more apt to watch it a lot, clocking four to five more hours in front of a television per week, the researchers said. Twice as many of the teens with a bedroom TV were classified as heavy TV watchers -- at least five hours a day -- compared to those without one.
Girls with a bedroom television reported getting less vigorous exercise -- 1.8 hours per week compared to 2.5 hours for girls without a TV. They also ate fewer vegetables, drank more sweetened beverages and ate meals with their family less often, the researchers said.
Boys with a bedroom TV reported having a lower grade point average than boys without one, as well as eating less fruit and having fewer family meals, the researchers said.
"It really clearly points out that there's some merit to not allowing your child to have a TV in the bedroom," said Daheia Barr-Anderson, one of the researchers.
"When you upgrade your TV in the living room and you have this smaller TV that's out of date but still usable, parents should really resist putting it in one of your children's bedrooms -- and resist the pressure from the child to have a TV in their bedroom," she said in a telephone interview.
