Good night's sleep may reduce risk of type 2 diabetes in obese teens

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.

 

"Reduced insulin secretion may lead to the higher glucose levels that we found in subjects who had insufficient sleep," said Koren. "We will seek to confirm these findings with home-based studies of sleep patterns in obese teenagers. In the meantime, our study reinforces the idea that getting adequate sleep in adolescence may help protect against type 2 diabetes."
