Australia faces its biggest challenge: Being overweight!

"This is the biggest public health challenge Australia's ever faced from any disorder," warns Professor Paul Zimmet, director emeritus of the Baker IDI Heart and Diabetes Institute and member of the Preventative Health Taskforce on Obesity, Tobacco and Alcoholsao2aivisceralfat2

Professor Zimmet doesn't see it as simply an issue of diet, he says hundreds of factors contribute to a society's weight, from food access to urban planning, "and we need to take a much wider approach to the problem.

"One of the major recommendations of the Preventative Health Taskforce was better urban planning to give the community better access to the right foods and the right exercise facilities."

Maternal nutrition is another factor identified by Professor Zimmet, "because we think one of the major drivers of the obesity, heart [disease] and diabetes epidemic in Australia is poor nutrition during pregnancy."

Dr Andrew Scott, Sleep Physician, adds that in recent years sleep research has confirmed that visceral obesity (associated with insulin resistance), is determined by both genetic/constitutional and environmental factors, and may be the principal culprit leading to sleep apnoea, which, in turn, may accelerate metabolic abnormalities, possibly through progressive elevation of stress hormones and cytokines such as cortisol, IL-6 and TNFα.plasmainsulinglucose

Plasma insulin and glucose levels were higher in patients with sleep apnoea than in obese controls. *P < 0.05.

Overall findings that support the view that sleep apnoea and sleepiness may be manifestations of a serious metabolic disorder, namely the Metabolic or Visceral Obesity Syndrome.
