Lack of Sleep Doubles Obesity Risk

Authorities generally agree that lifestyle factors are prime drivers of the surging obesity crisis. While lack of exercise and an improper diet are well known risk factors, a new association is gaining ground as a potential contributing factor – sleep deprivation.

Researchers reviewed current evidence in over 28,000 children and 15,000 adults and found in both groups, shorter sleep duration is associated with almost a two-fold increased risk of being obese.

Professor Francesco Cappuccio of the University of Warwick’s Warwick Medical School presented the findings at an international research conference this month.

The research also suggests that those who sleep less have a greater increase in body mass index and waist circumference over time and a greater chance of becoming obese over time.

Professor Cappuccio says:

“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 5 years.”

Professor Cappuccio points out that short sleep duration may lead to obesity through an increase of appetite via hormonal changes caused by the sleep deprivation. Lack of sleep produces Ghrelin which, among other effects, stimulates appetite and creates less leptin which, among other effects, suppresses appetite. However he 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.

Francesco Branca, the Regional Adviser for nutrition and food security in the World Health organisation (WHO) Regional Office for Europe said:

“This is an interesting piece of research putting together different lifestyle aspects with food choices. We need more research on the obese environment – the integration between medical research and socio-political research is something we should be exploring more.”
