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

  • In 2015, around one in five (21.6%) 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 pressure.
  • The rate varies marginally between the three metropolitan Adelaide Local Health Networks (LHNs) and the prevalence of high blood pressure among Country SA residents (21.7%) is essentially equivalent (no statistically significant difference) to the overall metropolitan Adelaide rate of 21.6%.
  • Over the last decade the proportion of people reporting living with high blood pressure has statistically significantly increased for metropolitan Adelaide residents but not Country SA.

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

  • In 2015, the proportion of males 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 (22.8%) was statistically significantly higher than the corresponding female rate (20.6%).
  • The prevalence of high blood pressure is correlated with age.

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

  • There is a statistically significant inverse 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 live.

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

  • Data presented here is from the Australian Bureau of Statistics’ 2014-15 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 2015 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 (24.5%) of South Australians estimated to be living with high blood pressure.
  • The South Australian rate is similar, given margins for error in the estimation, to the Australia-wide figure of 23.0% but it is – as was the case for the previous survey for 2011-12 – the state with the second-highest estimated prevalence rate of high blood pressure of the reported jurisdictions, only Tasmania having a higher rate.

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

  • In 2012, one in five (20.0%) Aboriginal people aged 15 years and over in South Australia self-reported that they were living with doctor-diagnosed high blood pressure and/or were on medication for high blood pressure.
  • Although the survey from which this data was drawn did not include the Anangu Pitjantjatjara Yankunytjatjara (APY) Lands, the Country SA rate as a whole (24.8%) is not statistically significantly higher than metropolitan Adelaide (17.6%).
  • However, the prevalence of high blood pressure amongst Aboriginal people in remote South Australia is extremely high at 39.8%.
  • The Aboriginal rate of persons aged 15 years and over for 2012 is roughly comparable to the 16 years and over all-population rate for 2014 reported for South Australia in 3-10-1 above (21.3%).
