complexity of disease causation

How Do Epidemiologists Study Disease Causation?

Epidemiologists employ various study designs to investigate disease causation:
1. Cohort Studies: These studies follow a group of people over time to identify the incidence of disease and its potential causes.
2. Case-Control Studies: These studies compare individuals with a disease to those without to identify factors that may contribute to disease development.
3. Cross-Sectional Studies: These studies assess the prevalence of disease and potential causative factors at a single point in time.
