Community-based interventions for obesity prevention: lessons learned by Australian policy-makers

<p>Abstract</p> <p>Background</p> <p>Interest in community-based interventions (CBIs) for health promotion is increasing, with a lot of recent activity in the field. This paper aims, from a state government perspective, to examine the experience of funding and managing six obesity prevention CBIs, to identify lessons learned and to consider the implications for future investment. Specifically, we focus on the planning, government support, evaluation, research and workforce development required.</p> <p>Methods</p> <p>The lessons presented in this paper come from analysis of key project documents, the experience of the authors in managing the projects and from feedback obtained from key program stakeholders.</p> <p>Results</p> <p>CBIs require careful management, including sufficient planning time and clear governance structures. Selection of interventions should be based on evidence and tailored to local needs to ensure adequate penetration in the community. Workforce and community capacity must be assessed and addressed when selecting communities. Supporting the health promotion workforce to become adequately skilled and experienced in evaluation and research is also necessary before implementation.</p> <p>Comprehensive evaluation of future projects is challenging on both technical and affordability grounds. Greater emphasis may be needed on process evaluation complemented by organisation-level measures of impact and monitoring of nutrition and physical activity behaviours.</p> <p>Conclusions</p> <p>CBIs offer potential as one of a mix of approaches to obesity prevention. If successful approaches are to be expanded, care must be taken to incorporate lessons from existing and past projects. To do this, government must show strong leadership and work in partnership with the research community and local practitioners.</p

Community-based efforts to prevent obesity: Australia-wide survey of projects

Issues addressed:&nbsp;Community-based programs that affect healthy environments and policies have emerged as an effective response to high obesity levels in populations. Apart from limited individual reports, little is currently known about these programs, limiting the potential to provide effective support, to promote effective practice, prevent adverse outcomes and disseminate intervention results and experience. The aim of the present study was to identify the size and reach of current community-based obesity prevention projects in Australia and to examine their characteristics, program features (e.g. intervention setting), capacity and approach to obesity prevention.Methods: Detailed survey completed by representatives from community-based obesity prevention initiatives in Australia.Results: There was wide variation in funding, capacity and approach to obesity prevention among the 78 participating projects. Median annual funding was Au$94 900 (range Au$2500&ndash;$4.46 million). The most common intervention settings were schools (39%). Forty per cent of programs focused on a population group of &ge;50 000 people. A large proportion of respondents felt that they did not have sufficient resources or staff training to achieve project objectives.Conclusion: Community-based projects currently represent a very large investment by both government and non-government sectors for the prevention of obesity. Existing projects are diverse in size and scope, and reach large segments of the population. Further work is needed to identify the full extent of existing community actions and to monitor their reach and future &lsquo;scale up&rsquo; to ensure that future activities aim for effective integration into systems, policies and environments.So what?: Community-based programs make a substantial contribution to the prevention of obesity and promotion of healthy lifestyles in Australia. A risk of the current intervention landscape is that effective approaches may go unrecognised due to lack of effective evaluations or limitations in program design, duration or size. Policy makers and researchers must recognise the potential contribution of these initiatives, to both public health and knowledge generation, and provide support for strong evaluation and sustainable intervention designs.</div
