In 2007–08, 61% of Australian adults were overweight or obese, based on measured data, compared to 57% in 1995.
In 2007–08, 24% of Australian adults were obese, based on measured data.
People with a higher body mass index (BMI) are at greater risk for Type 2 diabetes.
The proportion of Australian adults who do not already have Type 2 diabetes but are overweight or obese is an indicator of Australian adults who are at risk for Type 2 diabetes. Body Mass Index (BMI), based on measured and self-reported height and weight, is used to estimate this (AIHW 2011).
In Australia in 2007–08:
From 1995 to 2007–08:
Notes1. Directly age-standardised to the 2001 Australian population aged 18 years and over.2. Includes only those of whom body mass index (BMI) was known.3. Based on measured data.
Sources: AIHW analysis of ABS NHS 1995 and 2007–08 (reissue).
In the 18 years from 1989–90 to 2007–08:
Notes1. Directly age-standardised to the 2001 Australian population aged 18 years and over.2. Includes only those of whom body mass index (BMI) was known.3. Based on self-reported data.4. Note that measured data collected by the 2007–08 NHS indicated the underlying rate of overweight and obesity is slightly higher. 5. Data presented for 1989–90 are for persons aged 20 years or more whereas the data for other years are for persons aged 18 years or more.
Sources: AIHW 2011 analysis of ABS NHS 1989–90, 1995, 2001, 2004–05 and 2007–08 (reissue).
There are two main data sources:
These rates are directly age-standardised using the 2001 ABS ERP and compare:
Adults are people aged 18 years and over, with the exception of the NHS 1989–90, for which 'adults' were classified as 20 years and over.
Body Mass Index (BMI) is calculated by dividing a person's weight in kilograms by the square of their height in metres (kg/m2) (AIHW 2010). The standard classification of BMI recommended by the World Health Organization (WHO) for adults is based on the association between BMI and illness and mortality (WHO 2000):
