Epidemiologists identify risk factors for mortality through various research methodologies:
1. Cohort Studies: Following a group of people over time to observe how different exposures affect the death rate. 2. Case-Control Studies: Comparing those who have died (cases) to those who are still living (controls) to identify exposures that may be associated with mortality. 3. Cross-Sectional Studies: Analyzing data from a population at a specific point in time to identify risk factors associated with death.
