The medicalisation of prevention: health promotion is more than a pill a day

History and development of national burden of disease assessment in Australia

Australia's 1996 national burden of disease (BoD) study was one of the first in the world and updates have continued over the following two decades with the fifth study now underway. The studies adapt the global framework most recently implemented by the Global Burden of Disease Study and the World Health Organization to suit Australia's specific needs, producing estimates of fatal and non-fatal burden via the Disability Adjusted Life Year (DALY) metric, as well as attribution of the burden to many risk factors. Detailed Australian data are used with minimal reliance on modelling to fill data gaps. Comprehensive estimates are produced, including for the Indigenous population, for each of the eight states and territories, the five remoteness areas and five socioeconomic quintiles. A number of method developments have been made as part of these studies, including redistribution of deaths data and a detailed quality framework for describing the robustness of the underlying data and methods. Data and methods continue to be refined as part of the studies, and developments in global studies and other national studies are incorporated where appropriate.

Metabolic syndrome in rural Australia: An opportunity for primary health care

OBJECTIVE

To measure the impact of a 6-month home-based behaviour change intervention on reducing the risk of chronic disease as determined by metabolic syndrome status and cardiovascular risk score, and discuss implications for primary care in rural areas.

DESIGN

A two-arm randomised controlled trial of rural adults.

SETTING

The rural town of Albany in the Great Southern region of Western Australia.

PARTICIPANTS

Participants (n = 401) aged 50-69 years who were classified with or at risk of metabolic syndrome and randomly assigned to intervention (n = 201) or waitlisted control (n = 200) group.

INTERVENTIONS

A 6-month intervention program incorporating goal setting, self-monitoring and feedback, with motivational interviewing was conducted.

MAIN OUTCOME MEASURES

Change in metabolic syndrome status and cardiovascular risk.

RESULTS

Significant improvements in metabolic syndrome status and cardiovascular disease risk score (-0.82) were observed for the intervention group relative to control group from baseline to post-test.

CONCLUSION

This home-based physical activity and nutrition intervention reduced participants' risk of experiencing a cardiovascular event in the next 5 years by 1%. Incorporating such prevention orientated approaches in primary care might assist in reducing the burden of long-term chronic diseases. However, for realistic application in this setting, hurdles such as current national health billing system and availability of resources will need to be considered.
