BOSTON, April 25 (UPI) -- U.S. teens who pay "increased attention" to TV shows have higher body mass indexes, a measure of body fat, than teens who are less attentive, researchers say.
David Bickham of the Harvard-affiliated Boston Children's Hospital, who analyzed data on 91 teens ages 13-15, found it's how focused teens are on television programs rather than how long they watch that affects weight gain.
