More than one in three cases of disease and injury in Australia in 2024 could have been avoided, the Australian Institute of Health and Welfare (AIHW) study found.
The AIHW listed 20 risk factors including alcohol use, physical inactivity, poor diet, being overweight or obese and tobacco smoking.
While tobacco use had previously been the leading
risk factor contributing to disease burden, a 41 per cent decrease in the rate of its contribution since 2003 has seen being overweight become the most significant factor.
An estimated 8.3 per cent of total disease burden in 2024 was due to overweight (including obesity) and 7.6 per cent was due to tobacco use (excluding vaping). This was followed by dietary risks (4.8 per cent) and high blood pressure (4.4 per cent).
“While Australians are living longer on average, years lived in ill health are also growing, resulting in little change in the proportion of life spent in full health. This contributes to the growing demand and pressures on the health system and services,” said AIHW.
In line with previous years, cancer was the leading group of diseases causing burden in 2024 (16.4 per cent), with 91.3 per cent of this burden fatal and 8.7 per cent non-fatal.
The leading specific causes of disease burden were coronary heart disease (5.5 per cent), dementia (4.5 per cent), back pain and problems (4.3 per cent) and anxiety disorders (3.9 per cent).
