What to Measure to Show Impact
Evaluation designs should define and measure the reach, strength, and dose of obesity prevention and treatment interventions. Including these components will help contribute to the evidence base for policy, system, and environmental change strategies that work in rural communities.
Measured by how many people in a community are exposed to a particular strategy; For example, if 1,000 people begin using new bike lanes on a highway in a city of 10,000 people, the calculated reach is 10%.
Measured by the percentage improvement, from baseline, in day-to-day lifestyle changes that increase activity or improve diet.
Degree of change taking place in the population, measured by the reach plus the strength of the intervention.
