What are the Key Study Designs in Epidemiology?
Epidemiologists employ various study designs, each with its strengths and limitations. The most common designs include:
-
Descriptive Studies
: These studies describe the occurrence of diseases in populations, focusing on the "who, what, when, and where."
-
Analytical Studies
: These studies investigate the causes or determinants of disease, often through
case-control
or
cohort studies
.
-
Experimental Studies
: These involve interventions, such as
randomized controlled trials
, to assess the effect of specific treatments or preventive measures.
