National Healthcare Agreement: PI 03–Prevalence of overweight and obesity, 2018

Collection and usage attributes

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 years, 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 years, 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 years 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 years, based on centile curves. See Australian Health Survey: Users' Guide, 2011-13 (ABS catalogue no. 4363.0.55.001) for BMI values.

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

Excludes pregnant women where identified and people with an unknown BMI.

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.

100 × (Numerator ÷ Denominator)

Calculated separately for adults and children.

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

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

Adults: Population aged 18 years or over

Children: Population aged 5–17 years

For each of adults and children, state and territory, by:

• sex by age (adults only)
• Indigenous status
• remoteness (Australian Statistical Geography Standard (ASGS) Remoteness Structure)
• 2011 Socio-Economic Indexes for Areas (SEIFA) Index of Relative Socio-Economic Disadvantage (IRSD) quintiles
• BMI category (underweight, normal, overweight, obese)
• disability status

For adults, nationally, by:

• sex by remoteness (ASGS Remoteness Structure)
• 2011 SEIFA IRSD deciles
• remoteness (ASGS Remoteness Structure) by 2011 SEIFA IRSD deciles.

Some disaggregation may result in numbers too small for publication.

Most recent data available for 2018 National Healthcare Agreement performance reporting: 2014–15 (total population, non-Indigenous: NHS); 2012–13 (Indigenous only: NATSISS).

NO NEW DATA FOR 2018 REPORTING.

2014–15 data are based on measured height and weight. BMI derived from measured height and weight is preferable to that derived from self-reported height and weight.
