3-10-1. High blood pressure in South Australia – by Local Health Network

  • In 2018, more than a quarter (29.1%) of South Australians aged 18 years or more self-reported that they had current doctor-diagnosed high blood pressure and/or were on medication for high blood pressure1.
  • The rate varies between the local health networks (LHNs) from 24.3% in the Central Adelaide LHN to 35.5% in the Riverland Mallee Coorong LHN.
  • The prevalence of high blood pressure among Country SA residents (32.2%) is statistically significantly higher than the overall metropolitan Adelaide rate of 27.8%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.

3-10-2. High blood pressure in South Australia – by age and sex

  • In 2018, the proportion of females aged 18 years and over who self-reported that they were living with doctor-diagnosed high blood pressure and/or were on medication for high blood pressure (25.5%) was statistically significantly lower than the corresponding male rate (32.8%)1.
  • The prevalence of high blood pressure is correlated with age1.

3-10-3. High blood pressure in South Australia – by socio-economic status

  • There is no statistically significant correlation between the proportion of people aged 18 years and over who self-report that they are living with doctor-diagnosed high blood pressure and/or are on medication for high blood pressure and the socio-economic status of the area in which they live1.

3-10-4. High blood pressure in Australia – by state and territory

  • Data presented here is from the Australian Bureau of Statistics’ 2017-18 National Health Survey for people aged 18 years and over and is based on measured blood pressure which is 140/90 mmHg or higher. This is, therefore, not directly comparable to the information in 3-8-4 to 3-8-6 above which is based on people aged 18 years and over who self-reported having doctor-diagnosed high blood pressure and/or being on medication for high blood pressure.
  • The national survey does corroborate the findings from the state-specific survey, with about a quarter (23.0%, age standardised) of South Australians estimated to be living with high blood pressure2.
  • The South Australian rate is higher than the Australian average of 21.8% (age standardised) and is ranked third-highest of the states and territories2.

3-10-5. High blood pressure – Aboriginal people

  • In 2018-19, around one in three (30.4%) of Aboriginal people in South Australia aged 18 years and older were estimated to be living with high blood pressure3.
  • This is 7.4 percentage points higher than the 23.0% (age standardised) recorded for all South Australians aged 18 years or more in the ABS 2017-18 National Health Survey (see 3-9-4 above)2.
  • South Australia's high blood pressure prevalence rate for Aboriginal people is also higher than the national average for Aboriginal people (23.1%) and is ranked highest of the states and territories3.
