Your background question should answer the who, what, when, where, how and why. With a clinical question you will include the definition, epidemiology, clinical presentation, diagnosis and conclusion. As an example, when I am thinking of background questions that I would like to answer for my topic of depression I would ask:
1. How is Childhood obesity defined and how is it diagnosed in primary care?
2. What population is at the most risk for Childhood obesity?
3. What are some of the causes of Childhood obesity?
4. How is Childhood obesity identified and treated?
