4-5-1. Diabetes prevalence in South Australia – by Local Health Network

  • In 2018, around one in ten (10.8%) South Australians aged 18 years or more had ever been told by a doctor that they had diabetes1.
  • The rate varies between local health networks (LHNs) from 8.1% in the Central Adelaide LHN to 15.5% in the Riverland Mallee Coorong LHN1.
  • The metropolitan Adelaide rate (10.0%) is statistically significantly lower than the Country SA rate (12.8%)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.

4-5-2. Diabetes prevalence in South Australia – by age and sex

  • In 2018, the proportion of the population aged 18 years and over that had ever been told by a doctor that they have diabetes was statistically significantly higher for males (11.9%) than females (9.9%)1.
  • The prevalence of diabetes is correlated with age1.

4-5-4. Diabetes 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 who are or had been living with diabetes mellitus and is not directly comparable with data presented from the state-wide survey for ages 18 years and over in 4-5-1 to 4-5-3 above.
  • The national survey finds that around one in 20 (5.1%, age-standardised) of the South Australian population is living with diabetes mellitus. This is self-reported and includes Type 1 and Type 2 diabetes, and type unknown. Estimates also include persons who reported they had diabetes but that it was not current at the time of interview2.
  • The South Australian rate is above the Australian average (4.3%, age standardised) and is ranked second highest of the states and territories2.

4-5-5. Diabetes prevalence – Aboriginal people

  • The prevalence of diabetes mellitus in the South Australian Aboriginal population was 8.6% in 2018-19, 3.5 percentage points higher than that of the all-population prevalence (5.1%, age standardised) for this state in 2017-18 (see 4-5-4 above)2 3.
  • Compared to Aboriginal people in other states and territories, South Australia is ranked in the highest four for this indicator3.
  • The South Australian rate is above the national average for Aboriginal people (7.9%)3.
