4-2. Arthritis prevalence

In 2017, around a quarter (22.8%) of South Australians aged 18 years or more were living with arthritis¹.
The rate varies between local health networks (LHNs) from 15.4% in the Riverland Mallee Coorong LHN to 28.2% in the Northern Adelaide LHN.
There is no statistically significant difference between the Country SA rate of 23.0% and the metropolitan Adelaide rate of 22.7%¹.
No statistically significant underlying trend over the last decade in the proportion of people reporting living with arthritis was identified in the metropolitan Adelaide or Country SA time series¹.

In 2017, there was no statistically significant correlation between the proportion of people aged 18 years and over who are living with arthritis and the socio-economic status (SES) of the geographic area in which they live¹.
However, the rate in the lowest SES quintile (26.9%) is around double the rate in the highest SES quintile (14.2%)¹.

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.
