These studies differ from clinical investigations in that individuals have already been administered the drug during medical treatment or have been exposed to it in the workplace or environment. Epidemiological research helps us to understand how many people have a disease or disorder, if those numbers are changing, and how the disorder affects our society and our economy. PLAY.

ASPH C. EPIDEMIOLOGY COMPETENCIES ADDRESSED IN THIS CASE STUDY C. 3. C. 9. Within this framework, the most fundamental distinction is between studies of disease ‘incidence’ and studies of disease ‘prevalence’. The interpretation of study findings or surveys is subject to debate, due to the possible errors in measurement which might influence the results. The odds ratio is the measure of choice in a case-control study (see Lesson 1). C. 6. A quick look at the contents page of a biomedical journal or even at the health news section of a news website is enough to tell you that there are many different ways to conduct epidemiological research.
