Obesity intervention using system mapping

Identifying places to intervene in the obesogenic system in North Wales using system mapping.

Obesity intervention using system mapping

The Challenge

In Wales, approximately 60% of adults and 25% of children starting school live with unhealthy excess weight. A whole systems approach, using systems science methodologies, is ideally suited for the types of questions encountered in promoting a health weight because intervention targets typically are multilevel, multi-layered and embedded in complex social and environmental systems.

The approach

Betsi Cadwaladr University Health Board have identified three priority sub-systems. We will bring a range of stakeholders together to develop a detailed and shared understanding around these sub-systems by creating Causal Loop Diagrams (CLDs). CLDs are a visual depiction of the factors and relationships which cause a problem to occur. Emphasis is placed on identifying patterns within CLDs, whereby we can identify “feedback loops” - positive or negative chains of events which reinforce or balance out each other.

The Impact

We will identify and explain the dominant feedback structure within each sub-system and use these to identify potential places for intervention.
