Alongside co-researchers with a range of expertise, our team at the London Alliance for the Co-production of Evidence Synthesis have co-produced this model for child health. It depicts factors thought to impact healthy eating, physical activity, and mental health among young people. The model is focused on schools and is designed to support public health decision makers.
 
How to explore the logic model

To move around the model (displayed through a Kumu board), just click and drag to see different areas. You can also use your scroll wheel to zoom in and out. Use the search bar to find specific terms (for example, BMI) quickly, and click on any item to see more details.
 
What is represented in the model

Schools are potentially vital sites for intervening and improving children’s health, and this model helps us to think about which factors may influence a school’s capacity to influence children’s health. The model is broken down into seven levels of factors, from the individual level through to the economic level, which are displayed as concentric half circles. The factors are also divided into ten categories (for example, food, school, media) which are displayed in different colours. Demographic characteristics are displayed as a band crosscutting all levels to indicate that they intersect with all factors. Simply click on a factor to view further detail.
 
Why did we develop this logic model?

Healthy eating, physical activity, and mental health are complex challenges driven by multiple factors interacting at different levels. An understanding of this complexity is necessary to support public health decision makers in commissioning interventions, and researchers to improve the comprehensiveness of their work.
 
How did we develop this model?

LACES researchers and public co-producers with relevant lived/living experience (including parents, teachers, researchers, and young people) previously developed a logic model for child health. We recently worked as a smaller group of co-producers and elicited wider stakeholder feedback (including young people) to further refine and simplify the model. What you see here is this updated model.
 
What happens next?

This model represents a theory of influencers on children’s health. Using a combination of evidence synthesis and secondary data analyses, we are now in the process of further evidencing the elements and putative pathways that could be represented here.
