You are working with a third grade class with a high rate of obesity and many students at risk for type 2 diabetes. You want to incorporate regular exercise into their daily schedule but you need to be able to justify starting an after-school physical activity program to the school administration.
P = population (elementary school children at risk for developing type 2 diabetes)
I = Intervention (incorporating regular exercise into the daily schedule of the children)
C=Comparison (could be diet changes or medication)
This is a HOW question - you are looking for a solution to a problem.
