Using system mapping to help plan and implement city-wide action to promote physical activity.

Abstract

Background: There is growing interest in conceptualising public health problems such as physical inactivity as the outcome of multiple interacting factors within complex systems. A systems approach includes consideration of the indirect as well as direct impacts of interventions, the contexts within which they take place, the relations between the multiple factors at play, and the ways in which systems adapt in response to changes. This study involved working with stakeholders involved in a city-wide physical activity promotion programme in Derby, UK to investigate whether a conceptual map of the local physical activity system could be a useful tool to help improve the planning and implementation of the programme.Methods: We produced draft conceptual maps of the major modifiable drivers of physical activity in the city, based on the existing literature on determinants and correlates of physical activity, then refined them in a series of stakeholder meetings. The maps were used to explore ways in which the existing programme took a systems approach, and how it might be enhanced. Semistructured interviews were subsequently undertaken with stakeholders to assess their views on the contribution of the mapping approach.Results: Feedback from stakeholders described the mapping as valuable, especially in helping to identify the limitations of the original approach taken in the city.Conclusions: Even a very simple application of systems thinking can be a useful tool for disaggregating the key factors driving a system, helping to identify areas that merit greater attention, and supporting effective action.Significance for public healthThis paper has shown the value of using systems mapping to help stakeholders interested in complex public health problems take a broader view of the topic. This includes disaggregating the key factors driving a system, helping to identify areas that merit greater attention, and supporting effective action. This approach can be applied to any complex public health problem.
