Kids sleep v obesity.

Dr Janice F Bell has reported that night-time sleep duration in children under 5 is strongly associated with the risk of becoming overweight or obese 5 years later.

The researchers followed nearly 2,000 US children aged 0 to 13 for 5 years.

For those aged under 5, those in the lowest quarter of night-time sleep at the first check had an 80% higher risk of moving from normal weight to overweight, or overweight to obese, in the following 5 years.

Napping during the day did not make up for lost night-time sleep.

Above age 5, the base sleep measure was not predictive of future weight change.

The researchers noted that tired kids may exercise less and eat more, but as naps made no difference, perhaps the cause was an alteration to key hormones that regulate weight and metabolism.

Younger kids slept for an average of 10 hours each night at both time points with about an hour nap each day at baseline.
