Burden of disease
Burden of disease analysis measures the combined impact of morbidity (non-fatal burden) and mortality (fatal burden) to assess and compare the health loss from different diseases and injuries in a population. The non-fatal and fatal burden are added together to produce a single summary measure called disability-adjusted life years (DALY). One DALY is 1 year of ‘healthy life’ lost due to illness and/or death—the more DALY associated with a disease or injury, the greater the burden.
In 2018, across all disease groups, Aboriginal and Torres Strait Islander peoples experienced a higher rate of burden than non-Indigenous Australians.
The largest contributors to the gap in disease burden between Indigenous and non-Indigenous Australians (based on age-standardised DALY rate differences) were:
- mental and substance use disorders (20% of the gap)
- cardiovascular diseases (14%)
- injuries (10%) (AIHW 2022b).
