Our research program
Our four programs are led by key members of the unit and supported by internal and external partners and collaborators. The settings and research activities vary, as do the methodology and diversity of our programs.
We also have a multiple-partner research program in the Pacific region with an emphasis on NCD research. As part of our commitment to the World Health Organization (WHO), our unit performs a range of research initiatives that focusing on obesity prevention.
Monitoring of non-communicable diseases
In this stream our research projects have an epidemiological focus on monitoring the prevalence of non communicable diseases. Our flagship project, Heart Stats (Australian Heart Disease Statistics project) is led by Dr Melanie Nichols.
Australian Heart Disease Statistics (HeartStats) project
This project is a collaboration between our unit and the National Heart Foundation of Australia. The project presents the most comprehensive and up-to-date picture of coronary heart disease (CHD) and related risk factors in Australia.
Heart disease represents a major and avoidable burden to the health system and population. While the major behavioural and medical risk factors for heart disease are well known, estimating their prevalence in the Australian population can be challenge.
HeartStats collates and analyses existing data sources to provide insights for policy makers, health professionals and the public into the extent of the health burden of CHD in Australia.
The key objectives and outputs of our project are to:
- Document the current and recent burden of heart disease in Australia, including risk factors and comorbidities
- Describe the data available regarding heart disease mortality, morbidity, treatment and known modifiable risk factors
- Highlight limitations in availability of data monitoring heart disease and its risk factors
- Produce comprehensive annual compendia of heart disease statistics for Australia
- Produce annual supplementary reports addressing key aspects of or risk factors for heart disease.

Interventions with communities
Our interventions with communities stream has a long history working within communities on obesity prevention. It’s highlighted by the ‘Romp & Chomp, Be Active Eat Well’ and ‘It’s You’re Move’ community-based interventions projects.
Since these projects, the stream has expanded to new methodologies deepening understanding on strategies addressing obesity and NCDs. This has led to significant national and international collaborations where our researchers are working on community childhood obesity interventions.
This stream is led by Dr Claudia Strugnell and Dr Lynne Millar.
Our projects include:
- Health Together Victoria (HTV) and childhood obesity
- Systems Science to Guide whole of Community Childhood Obesity Interventions (COMPACT)
- Yarriambiack and Rural North West project
- Western Victorian Primary Health Network collaboration
- Sea Change Project with Western Alliance and Southern Grampians Glenelg Primary Care Partnership.

Food systems and policy analysis
This stream focuses on food environments and related food policy to generate evidence on improving the health of food environments in Australia and globally. The stream leaders are Dr Gary Sacks and Dr Adrian Cameron.
Our research includes:
- monitoring the healthiness of food environments
- understanding the policies and processes that shape food environments
- real-world trials of interventions to improve food environments, with a focus on supermarkets
- economic evaluation of policies and interventions
- analysing the influence of the food industry.
Key research initiatives
- Supermarket project (2015–2016) examines the impact of changes to within-store supermarket marketing and promotion strategies on the healthiness of food purchased.
- INFORMAS (International Network for Food and Obesity/non-communicable diseases Research, Monitoring and Action support) is global network of public-interest organisations and researchers that aims to monitor, benchmark and support public and private sector actions to create healthy food environments and reduce obesity and non-communicable diseases (NCDs) and related inequalities.
- Food-EPI Australia (2015–16) is funded by the Australian Prevention Partnership Centre,and will benchmark the obesity prevention policies of Australian state and federal governments through implementing the Food-EPI (Health Food Environment Policy Index) that INFORMAS has developed to assess government policy across 14 action areas relating to food environments.
- Centre of Research Excellence (CRE) in Policy Research on Obesity and Food Systems (2012–2017). This NHMRC-funded project includes the economic evaluation of 40 obesity prevention interventions across a range of sectors including food, trade, physical activity and urban design.
Pacific non-communicable disease research
This stream works with our Pacific partners, in particular Fiji National University, to support the C-POND initiative (Pacific Centre for Prevention of Obesity and NCDs). We aim to:
- evaluate the implementation and effectiveness of food-related policy in Pacific countries
- design new systems thinking approaches to enhance the use of evidence in policy making and make the process more efficient
- support salt reduction and contribute advice on regulatory approaches to improving the nutrition policy of skills.
Led by Dr Colin Bell and Prof. Marj Moodie, this research also enables our Pacific partners and countries to include strategies for improving food supply, food labelling and marketing regulations within their health policies.

Centre for Research Excellence
Our unit takes a leadership role for Deakin in its Centre for Research Excellence in Food Policy and Obesity Systems. This Deakin University-led centre brings together expertise from multiple disciplines. We apply innovative methodologies to address the complexity of obesity relating to a community response with emphasis on non-health environments.
Economic evaluation of obesity and chronic disease
Deakin Health Economics has significant expertise in applying economic evaluation and effectiveness techniques to obesity and other chronic diseases. Our unit works closely with the Economics of Obesity stream in the Deakin Health Economics Unit.
Innovative research projects
Our unit’s academic staff support a number of higher degree by research (HDR) students who are undertaking innovative projects focusing on obesity prevention, systems modelling and chronic disease prevention. The following is snapshot of these research activities.

Major project: Community-based Obesity Prevention Sites (CO-OPS)
Our unit developed and completed a national program, CO-OPS Collaboration that was funded from the Department of Health since 2007.
CO-OPS was a national knowledge translation and exchange platform encouraging health promotion professionals to apply latest research evidence in an effort to prevent obesity and related chronic diseases through a community-wide approach.
CO-OPS coordinated collaborative work between practitioners, researchers and policy officers to promote healthy eating, regular physical activity and healthy weight as key factors preventing chronic diseases.
CO-OPS also disseminated lessons learnt, reducing duplication of effort, maximising efficiencies and resources. Led by Professors Steven Allender and Boyd Swinburn, our unit worked with other universities and leaders in obesity research including Professor Elizabeth Waters at the University of Melbourne, Professor Tim Gill at the University of Sydney and Professor John Coveney at Flinders University.
The CO-OPS network had more than 2000 members, including different health agencies, all levels of government and non-government organisations. Its reach was an estimated 1.4 million Australians each year across all states and territories. Mechanisms to support the CO-OPS members included:
- tailored advice through a one-on-one knowledge brokering service
- access to the evidence informed resources
- professional development and capacity building opportunities
- networking opportunities, providing occasions to exchange knowledge development of resources such as the Best Practice Principles of Community-based Obesity Prevention and Monitoring Reports.
