Long-term data on girls are not yet available.

They also emphasize that parents should take the finding only as one more reason to focus on healthy sleep habits for their children -- not as a reason to worry.
The findings will be published in the April issue of Alcoholism: Clinical and Experimental Research by a team from the U-M Addiction Research Center (UMARC), in the Department of Psychiatry, and a colleague from Michigan State University.
The data come from an ongoing longitudinal project that uses interviews and standardized research questionnaires to look at mental and physical health issues in families over the long term.
