The twelve year follow-up survey in 2011/2012 revealed the following...

  • Every year, 0.7% of adults developed diabetes, 3% developed high blood pressure, 0.4–0.7% developed signs of kidney damage.
  • Living in the most socially-disadvantaged areas of Australia doubled the risk of developing diabetes.
  • Over 12 years, the average gain in waist circumference was 5.3 cm, and was greater in women than in men, and in younger people than in older people.
  • People with previously known diabetes have a similar risk of mortality to smokers.
  • Self-report physical activity time was approximately 50% greater than objectively measured physical activity time, whilst self-report sitting time was approximately half that measured by objective means.
  • Among the over 60s, cognitive impairment was more common among those with diabetes or with obesity.
  • Among the over 60s, having diabetes, obesity or kidney disease increased the risks of having physical disability.
  • Diabetes, obesity and kidney disease each increased the risks of having depression.
  • People with diabetes, obesity or kidney disease were more likely to be admitted to hospital than people without these conditions.

From the five year follow-up survey in 2004/2005, the key findings were…

  • Every day in Australia approximately 275 adults develop diabetes.
  • The average increase in waist circumference in Australians over 5 years was 2.1cm.
  • 4% of those in the overweight category in the 1999/2000 survey moved up into the obese category in the 2004/5 survey.
  • Those aged less than 65 years showed an average weight increase of 1.8kg over 5 years.
  • Every year, 3% of adults developed high blood pressure.
  • Every year, almost 1% of adults developed kidney disease, with the risk being higher in females and older people.
  • The percentage of people developing diabetes over the five years between the studies was twice as high for those who did no physical activity compared to those who did more than 150 minutes per week of physical activity.
  • People with pre-diabetes (elevated blood sugar levels but not as high as for diabetes) were 15 times more likely to develop diabetes than were those with normal blood glucose levels.
  • Obese people were 4 times more likely to develop diabetes than were those with normal weight.

From the baseline 1999/2000 AusDiab study we found that…

  • In 1999–2000, 7.5% of the Australian population aged 25 years and older had diabetes, 8.0 % of males and 7.0% of females. In people 75 years and over 23.6% had diabetes.

  • For every known case of diabetes, there was one undiagnosed case.

  • Almost 30% of adult Australians had elevated blood pressure or were on treatment for this condition.

  • One in six Australians participated in no physical activity, while only half of all Australians were participating in sufficient physical activity to maintain good health (defined as 150 minutes per week).

  • At the turn of the century, there were almost one million Australians with diabetes.

  • Almost 60% of Australians were classified as either overweight or obese, 2.5 times more than in 1980.

  • The number of people with diabetes has trebled since a broadly based blood survey was undertaken in 1981.

  • In comparison to people with normal glucose tolerance, those with diabetes were more likely to have hypertension (69.3% vs. 21.1%), to be obese (44.4% vs. 15.9%), to have elevated triglycerides (42.9% vs. 16.0%), and to have a depressed HDL-cholesterol (23.1% vs. 10.6%).

  • Almost 1 in 4 Australians 25 years and over has either diabetes or elevated blood sugar that is not quite in the range of diabetes (called “pre-diabetes”). Pre-diabetes is associated with substantially increased immediate risk of heart disease as well as increased risk of diabetes in the future.

  • Increased television viewing was shown to be strongly related to both obesity and the metabolic syndrome.

  • Approximately 16% of the population had some form of kidney damage present and were therefore at risk of renal disease, which consumes 5.7% of the health care budget.

With the rising number of Australians affected by diabetes, heart disease and stroke, the need for research is more critical than ever.
