The Epidemiological Landscape and Burden of Chronic Disease in Australia: Contextualizing the Distinct Profile of...

Chronic diseases are the leading causes of morbidity and mortality worldwide and impose a substantial and long-lasting burden on individuals, families, communities, and healthcare systems. In Australia, more than 47% of the population had at least one chronic condition in 2018, and the prevalence rose sharply with age: approximately 80% of adults aged 65 and over lived with one or more chronic diseases. These conditions are complex and driven by multiple factors, with modifiable behavioral risks such as poor diet, physical inactivity, tobacco use, and harmful alcohol consumption playing a major role. Although notable progress has been made since the implementation of the National Strategic Framework for Chronic Conditions 8 years ago, the overall burden of chronic diseases persists at a significant level. This ongoing burden highlights the need for more targeted evidence-based public health interventions that address these modifiable risk factors to reduce the prevalence of chronic diseases and improve population health outcomes.
