The following questions are based on the WHO’s Global Burden of Disease Report, 2004, Part 3 Disease Incidence, Prevalence and Disability (http://www.who.int/healthinfo/global_burden_disease/GBD_report_2004update_part3.pdf). What is the essential difference between prevalence & incidence? Why do we need 2 different measures? Couldn't we just use one instead? And if so, which one would you pick?The last paragraph on page 29 states “Variations across regions in the risk of cancer are best shown using age-standardized incidence”

Explain why the authors think using age-standardized incidence rates would be “best”?

What changes would you expect to see in Figure 18 if the authors had used crude incidence rates instead?

The measure YLD reported in section 13 of Part 3 is similar to the DALY measure in Gordis.

Explain why diseases such as heart disease and cancer (which are leading causes of death worldwide) rank lower than things like unipolar depressive disorders and hearing loss when we look at YLD?

Examine the results for Alzheimer’s and other dementias in Table 7. Which regions have the highest rates and which have the lowest? What factors could help explain these results?

Examine the results for “Hearing loss” in Table 9. Would it be correct to state that the risk of hearing loss increases with age? Explain why or why not.

What questions did you have about the Unit 1 material (if you don't have any, it is okay or if you think of one later and add it as a reply that is fine too.)
