WASHINGTON - Children who do not get enough sleep are more likely to be overweight than those who get more, according to a study published Wednesday that tracked more than 2,000 U.S. kids for five years. Researchers at Northwestern University in Evanston, Illinois, used detailed diaries kept by families to examine children's sleep behavior and its relationship with weight. "Children who get less sleep tend to weigh more five years later," lead researcher Emily Snell said in an interview. Snell and colleagues Emma Adam and Greg Duncan determined that an extra hour of sleep cut the likelihood of being overweight from 36 percent to 30 percent in children ages 3 to 8, and from 34 to 30 percent in those ages 8 to 13. The study, published in the journal Child Development, involved 2,281 children taking part in a nationally representative survey. They were ages 3 to 12 at the start of the study in 1997. Follow-up data was collected five years later. The diaries recorded the number of hours the kids slept, what time they went to bed and what time they woke up. Their height and weight also were recorded.
