New research has revealed that Aussie women have the fastest rising obesity rate in the world.
According to the Daily Telegraph, for the first time Australian women are close to matching America's obesity level.
The study compared the body mass index (BMI)- weight divided by height - of Aussie women with their counterparts in the US, China and the UK and found that their BMI is rising faster than other nations.
The research analysed the top 5percent of obese women in Australia at age 30 and came up with an average BMI score of 37.7.
The index's increase over a decade has been more than twice the international average.
Many experts say Australia's obesity level has already caught up to America, where the top 5percent of women averaged a BMI score of 42.5.
According to the World Health Organisation women having a BMI of more than 34.9 are critically obese.
Health experts are now warning women over 30 years of age not to be complacent about gaining weight.
"What we have known is that for the past five years, people have been gaining weight and they are women aged between 25 and 35," News.com.au quoted Professor Ian Caterson, director of the Institute of Obesity, Nutrition and Exercise, as saying.
