Researchers at the Ohio State University looked into 18.6 million visits to doctors by children ages 6 to 12 years who had problems falling asleep. Three-quarters of them received prescription sleep aids that have not been approved by the Food and Drug Administration for use by children.

"The concern with sleep medications is that we do not know how much to use and how long to use these drugs for children," said Professor Milap Nahata of the College of Pharmacy in Columbus. He and his colleagues collected data recorded between 1993 and 2004 by the National Ambulatory Medical Care Survey.

A 2004 study from the National Sleep Foundation found that about 60% of children under age 11 have trouble sleeping. Dr. Nahata's study appears in the August 1 issue of Sleep.
