Background:
Findings from multiple community-based obesity prevention interventions have shown that multi-component, multi-level, capacity-building initiatives can reduce obesity levels. However, lingering questions that remains unanswered centre on the degree to which the community can lead prevention efforts and the ongoing sustainability of these community-led interventions. This question was tested in a rural remote local government area of Victoria where adult overweight and obesity prevalence was 16% above the State average. The rural health service requested assistance to reduce avoidable hospital admissions due to chronic disease complications. This catalysed action for the community-collaborative effort which became YCHANGe.
Methods:
In this community-led intervention, community-based systems dynamics was combined with the Collective Impact Framework and action based research to define the local determinants of obesity, common agenda, nature and scope of the multiple interventions. Evaluation methods included: community readiness assessments, community-based systems dynamics, workforce audit, policy audit and changes in: kindergartens, workplaces, schools, food supply audit, pre-existing anthropometric data analysis, sales data, lunchbox audits and key informant interviews - all within a collaborative framework under a multi-stakeholder governance structure.
Results:
A selection of results include: the local children at 3.5 years recorded a lower prevalence of overweight and obesity compared to the state’s average (11.4% c.f. 20%). Discretionary foods in kindergarten lunchboxes was significantly reduced (p=0.05). Workforce audits revealed 1.3 EFT available for obesity prevention (7000 sq kms).
Conclusion:
This community-led obesity prevention intervention found that children in this LGA begin life within a normal weight range despite the high overweight and obesity prevalence experienced by the adult population. We concluded a rural community can lead some prevention activities that fall within its remit, but the broader systemic issues of food supply require policy support and additional human resources to build and sustain these improvements.
