This blog post is not about the rate of obesity. Let me make this clear. I get a bit annoyed with repeated news stories about Australia being the 3rd fattest, 2nd fattest or the fattest this week.
This week, more data from the Australian Institute of Health and Welfare came out to show how fat our nation is - about 62% of Australians are overweight or obese. It's a repeating story and unless we change the message people will get sick of it.
We just need to look after our metabolism and then obesity will be reduced. It's Type 2 Diabetes (T2D) that I'm worried about because this occurs when your normal metabolic function fails. It fails mostly due to lack of physical activity and overeating. And you don't need to be obese to have poor metabolic function.
This why I listened with great interest yesterday, to Professor Paul Zimmet's session at the National Heart Foundation Conference in Brisbane. Here's a summary of points from my quick and messy notes made in dark corner of the lecture theatre. We've engineered physical activity out of our lives.
In December 2006, the United Nations General Assembly voted to make diabetes a major public health issue, second only to HIV aides.
In April 2008, Prime Minister Kevin Rudd made the statement that diabetes is one of the biggest diseases we will face in Australia.
Worldwide, in the year 2025 there will be 409 million people with Impaired Glucose Tolerance (IGT) and 380 million people with Type 2 Diabetes (T2D).
In Mauritius (island off east coast of Africa), diabetes has increased from 14.3% in 1987 to 19.5% in 1998. This is an increase of 40% in just over a decade.
In urban India, T2D increased by 40% between 2000-2006 with 40-50% of adults having T2D. Before 1980, there was virtually no T2D diagnosed.
New data reveals if you have high blood pressure and T2D, you can be looking at a 3.5 time increased risk of death.
Here's how T2D has increased in Australia:
1981 - 250,000 people
1983 - 320,000
1990 - 550,000
1995 - 725,000
2000 - 1,000,000
Australian Bureau of Statistics data reports that 880,000 Australians now say they have T2D. Prof Zimmet says an equal number are likely to have it but not realise it. Therefore, T2D affects 1.5 million Australians.
Those with the lowest physical activity level and the highest TV viewing hours had 2.3 time increased risk of metabolic syndrome (high blood pressure, high cholesterol, high blood sugars and a big waist measurement).
Professor Zimmet stressed that non-diabetic glycaemia (the rise in blood sugars that occur before you actually get diagnosed with IGT or T2D) occurs early and that prevention is vital. It's too late in many cases to try to cure diabetes.
All this data shows just how easy it is to get Type 2 Diabetes if you don't look after your metabolism. It's almost like if you don't exercise ot stay active, you will get T2D.
This motivates me to stay in shape. I want my metabolism to work well and I don't want to get T2D. It also inspires me to help others to do the same. It's not about obesity rates. It's about being active and eating well at any shape. This is what stops T2D.
