Variation among population groups
Aboriginal and Torres Strait Islander people
In 2020–21, there were around 5,400 hospitalisations with a principal diagnosis of CHD among Aboriginal and Torres Strait Islander people.
After adjusting for differences in the age structure of the populations:
- the rate among Indigenous Australians was 2.1 times as high as the non-Indigenous rate (1,038 and 483 per 100,000 population)
- the disparity between Indigenous and non-Indigenous Australians was greater for females than males—3.1 times as high for females (842 and 274 per 100,000 population) and 1.8 times as high for males (1,265 and 709 per 100,000 population) (Figure 7).
In 2020–21, CHD hospitalisation rates were almost 20% higher for people living in the lowest socioeconomic areas compared with those in the highest socioeconomic areas—age-standardised rates of 558 and 472 per 100,000 population.
The disparity was greater for females (347 and 246 per 100,000 population) than males (781 and 720 per 100,000 population) (Figure 7).
In 2020–21, CHD hospitalisation rates were around 50% higher among those living in Remote and very remote areas compared with those in Major cities (age-standardised rates of 745 and 486 hospitalisations per 100,000 population).
This largely reflects disparities in female rates, which were twice as high in Remote and very remote areas as in Major cities (549 and 272 per 100,000 population)—while male rates were 1.3 times as high (919 and 724 per 100,000 population) (Figure 7).
