Measures of Disease Morbidity and Mortality
1. You were recently hired as an epidemiologist at a county office. List and explain three
measures that you would use to calculate a specific disease situation. In your view, why is it
difficult to get accurate information about disease status in a population?
2. A study starts with 4,875 health people. Over the next 2 years, 75 develop the disease. What
is the incidence rate of disease over the study period? Show all work.
3. In a survey of 1,150 women who gave birth in Maine in 2000, a total of 468 reported taking a
multivitamin at least 4 times a week during the month before becoming pregnant. Calculate the
prevalence of frequent multivitamin use in this group.
