The L.E.A.D. Framework: Using Tools From Evidence-Based Public Health to Address Evidence Needs for Obesity Prevention

The figure has a diamond-shaped outer frame. Two sides are labeled “Systems perspective”; the other 2, “Opportunities to generate evidence.” Inside the diamond is a column of boxes that describe each element in the L.E.A.D. process. At the top is a circle that reads, “Specify questions.” The four boxes read as follows: “Locate Evidence: Identify and gather the types of evidence that are potentially relevant to the questions; Evaluate Evidence: Apply standards of quality as relevant to different types of evidence; Assemble Evidence: Select and summarize evidence according to considerations for its use; Inform Decisions: Use evidence in the decision-making process.”
