Lack of sleep 'increases obesity risk'

Those who suffer from sleep deprivation also run a greater risk of becoming obese, according to newly-released research.

A study conducted by the University of Warwick's Medical School found those who sleep less have a greater increase in body mass and waist circumference over time.

Early results of a study by Professor Francesco Cappuccio showed that a lack of sleep was associated with an almost two-fold increase in obesity levels for both children and adults.

Commenting on the findings, Prof Cappuccio said: "The 'epidemic' of obesity is paralleled by a 'silent epidemic' of reduced sleep duration - with short sleep duration linked to increased risk of obesity both in adults and in children.

"These trends are detectable in adults as well as in children as young as five."

The professor pointed out that short sleep duration may lead to obesity through an increase of appetite via hormonal changes caused by sleep deprivation. Lack of sleep produces ghrelin, a hormone which, among other effects, stimulates appetite.

However, Prof Cappuccio says more research is needed to understand the mechanisms by which short sleep is linked to chronic conditions of affluent societies, such as obesity, diabetes and hypertension.

The research reviewed current evidence relating to more than 28,000 children and 15,000 adults.
