        Kids who watch more TV or even have TVs in their bedrooms get less sleep, a U.S. study said Monday.

Researchers from MassGeneral Hospital for Children and Harvard School of Public Health found "a small but consistent association" between increased TV viewing and shorter sleep (1) after studying more than 1,800 children (2) from 6 months to nearly eight year.

        The (3) of a television in the room where a child sleeps was also associated with less sleep, (4) in minority children, the researchers said.

        The study participants, children and their mothers, were enrolled in Project Viva, a long-term (5) of the health effects of several factors during pregnancy and after birth.

        From the time the children were around six months old, and then on a yearly basis for the next seven years, mothers reported how much time each day (6) were in a room where a TV was on, how much time older children watched TV daily, whether children aged four to seven slept in a room where a TV was present and their child's (7) daily amount of sleep.

        The researchers found each (8) hour of TV viewing was associated with seven fewer minutes of sleep daily, with the effects (9) to be stronger in boys than in girls.

        For racial and ethnic minority children, the presence of a bedroom TV reduced average sleep around a half-hour per day.

        The results support previous short-term studies finding that both TV viewing and sleeping in a room with a TV (10) total sleep time, which can have negative effects on both mental and physical health, the researchers said.
