Researchers at the University of South Australia say that children are going to bed half-an-hour later than they did 20 years ago. Study author Dr Jim Dollman says although children are waking up at about the same time at around 7:00am, they are now going to bed later.
He says children aged between 10 and 15 years, on average, now go to bed at about 10:15pm, which is half-an-hour later than in 1985.
Dr Dollman says the lack of sleep could be a cause of higher weight levels in children.
"That’s the difference in sleep duration between overweight and normal weight children, according to a recent study overseas," he said.
"So it may well be that the 30-minute reduction is contributing in the increase in the prevalence of overweight that we’re seeing among children."
