Computation description:

Proxy measure:

The National Health Measures Survey component of the 2011–13 Australian Health Survey (cat. no. 4364.0.55.005) included a fasting plasma glucose test.

A respondent to the survey is considered to have known diabetes if they had ever been told by a doctor or nurse that they have Type 2 diabetes and:

  • They were taking diabetes medication (either insulin or tablets); or
  • Their blood test result for fasting plasma glucose was greater than or equal to 7.0 mmol/L).

A respondent to the survey is considered to have newly diagnosed diabetes if they reported no prior diagnosis of diabetes, but had a fasting plasma glucose value greater than or equal to 7.0 mmol/L.

Excludes persons who did not fast for 8 hours or more prior to their blood test.

Excludes women with gestational diabetes.

Population is limited to persons aged 25 years and over.

Rates are directly age-standardised to the 2001 Australian population.

Analysis by remoteness and Socio-Economic Indexes for Areas (SEIFA) Index of Relative Socio-Economic Disadvantage (IRSD) is based on usual residence of person (subject to data availability).

Presented as a percentage.

95% confidence intervals and relative standard errors calculated for rates.

Note: The type of diabetes for newly diagnosed cases cannot be determined from a fasting plasma glucose test alone.  However, it is assumed that the vast majority of newly diagnosed cases would be Type 2.

Comments:

Most recent data available for 2014 Council of Australian Governments (COAG) Reform Council (CRC) report: 2011–12.

Results for the Aboriginal and Torres Strait Islander population will be available in 2014.

The baseline measure of 7.1 per cent is calculated from the Australian Diabetes, Obesity and Lifestyle Study conducted in 1999–2000. Note that this number was age-standardised to the average of the 1999 and 2000 Australian populations, and was based on data from both oral glucose tolerance tests (OGTTs) and fasting plasma glucose tests. As an OGTT was not conducted as part of the National Health Measures Survey, the data supplied for the 2014 CRC report are not comparable to the baseline measure of 7.1 per cent.

Fasting plasma glucose test data will be supplied as a proxy from the AHS for this benchmark, age-standardised to the 2001 Australian population.  The equivalent baseline measure from the Australian Diabetes, Obesity and Lifestyle Study, age-standardised to the 2001 Australian population and using fasting plasma glucose test data, has been calculated to be a rate of 5.0%.
