ScienceDaily (Sep. 22, 2011) — Obese teenagers who don't get the proper amount of sleep may have disruptions in insulin secretion and blood sugar (glucose) levels, say pediatric researchers. Their study suggests that getting a good night's sleep may stave off the development of type 2 diabetes in these adolescents.

"We already know that three out of four high school students report getting insufficient sleep," said study investigator Dorit Koren, M.D., a pediatric endocrinologist at The Children's Hospital of Philadelphia. "Our study found to keep glucose levels stable, the optimal amount of sleep for teenagers is 7.5 to 8.5 hours per night." She added that this is consistent with research in adults showing an association between sleep deprivation and increased risk of type 2 diabetes.
