Infants and toddlers who sleep less than 12 hours a day are twice as likely to become overweight by age 3 than children who sleep longer. In addition, high levels of television viewing combined with less sleep elevates the risk, so that children who sleep less than 12 hours and who view two or more hours of television per day have a 16 percent chance of becoming overweight by age 3.
“Mounting research suggests that decreased sleep time may be more hazardous to our health than we imagined,” says Elsie Taveras, MD, assistant professor in Harvard Medical School’s Department of Ambulatory Care and Prevention and lead author on the study. “We are now learning that those hazardous effects are true even for young infants.”
Results are published in the April 2008 issue of Archives of Pediatric and Adolescent Medicine.
