Collection and usage attributes

Computation description:

Body Mass Index (BMI) is calculated as weight (in kilograms) divided by the square of height (in metres).

For adults, underweight is defined as a BMI less than 18.5, normal is defined as a BMI of 18.5 to less than 25.0, overweight is defined as a BMI of 25.0 to less than 30.0 and obese is defined as a BMI of greater than or equal to 30.0.

For children, underweight is defined as a BMI (appropriate for age and sex) that is likely to be less than 18.5 at age 18, normal is defined as a BMI (appropriate for age and sex) that is likely to be 18.5 to less than 25.0 at age 18, overweight is defined as a BMI (appropriate for age and sex) that is likely to be 25.0 to less than 30.0 at age 18 and obese is defined as a BMI (appropriate for age and sex) that is likely to be greater than or equal to 30.0 at age 18, based on centile curves. See Appendix 4: Classification of BMI for children in Australian Health Survey: Users' Guide, 2017–18 (ABS cat. no. 4363.0.55.001) (ABS 2019c) for BMI values.

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

Excludes pregnant women where identified. For people who did not have their height or weight measured, height and weight were imputed (see comments below for more details).

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

Presented as a percentage.

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

Computation:

100 × (Numerator ÷ Denominator)

Calculated separately for adults and children.

Numerator:

Adults: Number of persons aged 18 and over who are overweight or obese.

Children: Number of persons aged 5–17 who are overweight or obese.

Comments:

Most recent data available for 2021 National Healthcare Agreement performance reporting: 2017–18 (total population, non-Indigenous: NHS); 2018–19 (Indigenous only: NATSIHS).

NO NEW DATA FOR 2021 REPORTING.

Data are based on measured height and weight, though respondents were also asked to self-report their height and weight. BMI derived from measured height and weight is preferable to that derived from self-reported height and weight.

In the 2017–18 NHS, 33.8% of respondents aged 18 years and over did not have their height or weight measured. For these people, height and weight were imputed using a range of information including their self-reported height and weight. For more information see Appendix 2: Physical measurements in the 2017–18 National Health Survey in National Health Survey: First results, 2017–18 (ABS cat. no. 4364.0.55.001) (ABS 2019b).

In the 2018–19 NATSIHS, 55.8% of respondents aged 18 years and over did not have their height or weight measured. For these people, height and weight were imputed using a range of information including their self-reported height and weight. For more information see Explanatory notes in the National Aboriginal and Torres Strait Islander Health Survey, 2018–19 (ABS cat. no. 4715.0) (ABS 2019a).
