The Sentinel Site for Obesity Prevention
The Sentinel Site for Obesity Prevention grew out of the urgent need to build
the evidence on effective strategies for reducing the growing epidemic of obesity.
Overweight and obesity affected 20% of Australian boys and 21% of Australian
girls in 1995 compared to 11% and 12% in 1985 and preliminary data collected
in March 2003, indicate that 27.5% of children aged 4 – 12 years are
overweight or obese, similar to other regional surveys. In the face of
this escalating epidemic, we know very little about which programs work to
prevent
obesity. Evaluating the effectiveness and sustainability of
multi-strategy, multi-setting interventions is paramount.
Aim
The aim of the Sentinel Site for Obesity Prevention
is to build the programs, skills and evidence necessary to prevent obesity
among children and adolescents. The two main questions being investigated are:
- What is the impact of multi-strategy, multi-setting obesity prevention programs
on obesity prevention?
- What is the impact of individual components of a multi-strategy,
multi-setting program?
Features and Innovations
- Focusing resources
into a defined geographical area:
By focusing funding, training programs, research expertise and other resources
into a defined geographical region, programs can be developed and the evidence
gathered about effectiveness and sustainability before they are rolled out
into other regions.
- Community capacity building:
Building the knowledge and skills of community workers, teachers and health
professionals in obesity prevention and physical activity and nutrition promotion
encourages ownership of the programs and sustainability.
- Multi-strategy, multi-setting intervention programs:
A myriad of individual and environmental causes are contributing to the epidemic
and a variety of innovative strategies are needed to address these underlying
causes in a number of settings.
- Monitoring:
Physical activity and nutrition indicators are needed to monitor the obesity
epidemic. Data from a monitoring program will also act as a comparison group
and allow measurement of the impact of the intervention programs.
- Evaluation:
Establishing a partnership with Deakin University gives communities access
to expert research skills so that the intervention programs are well supported
and evaluated. This partnership also ensures that the findings are disseminated.
Significance of the Sentinel Site for Obesity
Prevention Project
This Sentinel Site project will be important not only for the Barwon-South
Western region of Victoria but will be a leading program of its type in Australia
and internationally. The evidence that will come from the project will help guide similar community-based
programs and hopefully stimulate a more vigorous response to the obesity epidemic.
The innovation of linking regional monitoring programs with local demonstration
communities could be particularly important. Ideally a group of similar sites
would be developed and linked into a collaborative network that develops and
shares instruments, designs, methodologies, and results. Internationally, this
project is also very important, with the World Health Organisation and the
International Obesity Task Force both advocating this approach to obesity prevention.
