Objective: We present a framework causal loop diagram for
the Caribbean that links the complex modifiable determinants of childhood obesity (social, economic, and environmental) using a stakeholder-driven systems approach.
Methods: A participatory systems dynamic modeling approach was used to engage key stakeholders in Barbados, Puerto Rico, Trinidad & Tobago, and the US Virgin Islands to generate a causal loop diagram to represent the many interacting factors that lead to, and result from, rising childhood obesity. Through stakeholder engagement these diagrams were used to identify priority intervention areas and themes that represent a common causal loop for childhood obesity in the Caribbean
Results: Determinants and drivers of childhood obesity common across islands included the role of government policies in driving healthy school environments and healthy households, the role of commercial entities in informing government policies and households, the role of societal norms accepting childhood obesity that result from the rising rates of childhood obesity and continued unhealthy households and communities, and the effect of obesity on the physical and mental health of the child which further drives unhealthy behavior. To address the challenge using the diagrams, stakeholders favored a global and all-encompassing intervention that worked with policymakers, communities, parents, and the children themselves for a healthier environment.
Conclusion: Participatory systems dynamics led to a deep understanding of the drivers and determinants of childhood obesity across the Caribbean. This allowed the identification of priority areas for intervention emphasizing the importance of a multi-faceted and multi-sectoral approach.
