This web report contains results from the Australian Bureau of Statistics (ABS) National Health Survey (NHS) 2017–18, collected between July 2017 to June 2018.
The 2017–18 NHS is the most recent in a series of Australia-wide health surveys conducted by the ABS. It was designed to collect a range of information about the health of Australians, including:
The 2017–18 NHS collected data on children and adults living in private dwellings but excluded persons living in non-private dwellings, very remote areas and discrete Aboriginal and Torres Strait Islander communities.
For further information, refer to the ABS National Health Survey: First Results, 2017–18.
This release includes the following indicator by Primary Health Network (PHN):
Proportions have been age standardised to the 2001 Australian population to account for differences in the age structure of the population for different areas.
Results are presented as both crude and age-standardised rates.
Total high blood pressure includes all persons with a high, very high or severe (from 140/90 mmHg) measured or imputed blood pressure (regardless of whether taking hypertension medication) as well as persons with normal/low (<140/90 mmHg) measured or imputed blood pressure who reported they were taking hypertension medication. Hypertension medication includes Antihypertensives (C02), Diuretics (C03), Beta blocking agents (C07), Calcium channel blockers (C08) and Agents acting on the renin-angiotensin system (C09).
Uncontrolled high blood pressure includes all persons with measured high blood pressure (systolic ≥140 and/or diastolic ≥90) regardless of whether they were taking high blood pressure medication Measured high blood pressure excludes self-reported hypertension prevalence rates.
In 2017-18, 31.6% of respondents aged 18 years and over did not have their blood pressure measured. For these respondents, imputation was used to obtain blood pressure. For more information see Appendix 2: Physical measurements in the 2017–18 National Health Survey (ABS 2018a).
Primary Health Networks (PHNs) are local organisations that connect health services across a specific geographic area, with the boundaries defined by the Australian Government Department of Health.
The quality of estimates from the NHS can vary across PHN areas, as the survey was not specifically designed to produce estimates at this level of geography.
As an indication of the accuracy of proportions, 95% confidence intervals were produced. These were calculated by the ABS using relative standard error (RSE) estimates of the proportion.
To ensure robust reporting of these data by PHN areas, suppression or interpret with caution rules were developed and applied by the Australian Institute of Health and Welfare.
Estimates of a percentage or its complement that had a relative standard error greater than 50% were suppressed. These estimates were considered unreliable for most practical purposes.
Data for PHN areas were suppressed if there was the likelihood of a non-representative sample, that is, where the survey sample count in the PHN area was less than 20% of the expected number of adults.
The ‘interpret with caution’ flag was applied to the data if the relative standard error associated with the percentage or its complement was greater than 25%. This indicates the proportion derived is subject to high sampling error and should be used with caution.
Data for Northern Territory should be interpreted with caution as the NHS excluded discrete Aboriginal and Torres Strait Islander communities and very remote areas, which comprise around 28% of the estimated resident population of the Northern Territory.
