Variation among population groups
Aboriginal and Torres Strait Islander people
In 2018–19, 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 (1,103 and 516 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 (920 and 295 per 100,000 population) and 1.7 times as high for males (1,312 and 756 per 100,000 population) (Figure 7).
Socioeconomic group
In 2018–19, CHD hospitalisation rates were almost 30% higher for people living in the lowest socioeconomic areas compared with those in the highest socioeconomic areas—age-standardised rates of 609 and 475 per 100,000 population.
The disparity was greater for females (382 and 246 per 100,000 population) than males (853 and 727 per 100,000 population) (Figure 7).
Remoteness area
In 2018–19, CHD hospitalisation rates were around 45% higher among those living in Remote and very remote areas compared with those in Major cities (age-standardised rates of 742 and 510 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 (566 and 287 per 100,000 population)—while males rates were 1.2 times as high (895 and 759 per 100,000 population) (Figure 7).
