Physical inactivity poses health risks for the majority of Australian adults and is a modifiable risk factor for diseases like cardiovascular disease and diabetes. While guidelines recommend at least 150 minutes of moderate physical activity per week, surveys found about 40% of Australians do not meet this level. Individual education interventions have shown only moderate short-term effectiveness in increasing physical activity levels. Environmental interventions also have limited effectiveness, and population physical activity levels remain largely unchanged. Intersectoral actions across multiple areas may be needed to more successfully promote physical activity.

Editor's Notes
- Face to face interviews for both Australia – ABS SA – SA Dept of Health Less than half population undertaking sufficient physical activity Large proportion of sedentary Pattern of physical inactivity is fairly stable across age groups
- “ obesogenic environments” – anecdotal evidence re changes in lifestyle over recent decades Because there is some differential distribution of physical inactivity, this would suggest that there is not a ‘one size fits all’ approach
- Given that there are some socio-demographic differences, it may be necessary to target some subgroups of the population through policy and environmental interventions Health belief model – the perception people have about risks of not undertaking sufficient physical activity, and whether or not they feel enabled and empowered to undertake sufficient physical activity, determines in part whether or not they do Does not include the complexity or need for sustained change
- Examples: inadequate car parking, distance from local shops through council planning
- Once broader environmental and policy initiatives are in place, then individual behaviour modification can be addressed Incorporates some of Ottawa charter – Creating supportive environments, Building healthy public policy Addresses some issues associated with social inequality and economic disadvantage More coordinated big picture approach than what we have been able to uncover in the literature
