Describe how your intervention design would allow a scientific impact evaluation.

a) Suppose you are a health economist at the state Department of Health, responsible

(prevent obesity) among the school students in grades 5-12. (10 marks)
b) Suppose the Health Department has agreed to implement your intervention. You are
required to provide a report on the impact of your intervention measured one year
after the implementation.
i. Describe how your intervention design would allow a scientific impact
evaluation. (5 marks)
ii. Discuss the strengths and weaknesses of the intervention in the light of short
versus longer term impacts and potential unwanted side-effects. (5 marks)
c) Describe in detail, with some plausible data on the cost and benefit components, the
process of an economic evaluation of the intervention suggested in part (a) using costeffectiveness analysis. (20 marks)
