4-2-1. Arthritis prevalence in South Australia – by Local Health Network

  • In 2018, around a third (30.2%) of South Australians aged 18 years or more were living with arthritis1.
  • The rate varies between local health networks (LHNs) from 24.0% in the Flinders and Upper North LHN to 43.7% in the Yorke and Northern LHN.
  • The Country SA rate of 35.3% is statistically significantly higher than the metropolitan Adelaide rate of 28.1%1.
  • No time series is available for this indicator due to a change in survey methods. In 2018, SA Health discontinued the South Australian Monitoring and Surveillance System (SAMSS) and moved to the improved South Australian Population Health Survey (SAPHS). Results between the collections are not comparable.

  • Arthritis prevalence is also correlated with age1.

4-2-4. Arthritis prevalence in Australia – by state and territory

  • Data presented here is from the Australian Bureau of Statistics’ 2017-18 National Health Survey for people of all ages reporting living with arthritis. This is not directly comparable with data presented from the state-wide survey for ages 18 years and over in 4-2-1 to 4-2-3 above.
  • The national survey reports that an estimated 14.5% (age standardised) of the population in South Australia is living with arthritis2.
  • The South Australian rate is a little higher than the Australian average (13.3%, age standardised) and is ranked third highest of the states and territories2.
