Causal Loop Diagrams of Food Systems, Diet, and Obesity: A Scoping Review of Methods, Contextual Factors, and Outcomes

Urban Farm DB summary

This scoping review characterized 40 peer-reviewed studies from 1370 unique records, identified through a comprehensive search of six databases, that used interest-holder-driven causal loop diagrams to examine food systems, diet, and obesity. All studies identified individual and behavioral drivers of obesity, while studies in the Global South and those engaging minoritized populations more frequently emphasized structural factors like racism, urban agriculture, and gentrification. The review highlights the potential of causal loop diagrams to capture the complexity of these issues and identifies gaps in geographical coverage and population representation.
