Why?
Analytic Epidemiology correct answer -Analytic epidemiology examines the causes
of health- related states or events - The'Why'
-Analytic epidemiology quantifies the association between
exposures and outcomes to determine causal
relationships
-Examines potential etiologies (helpful or harmful) for the
health-related states or events
-Analytic epidemiology studies the DETERMINANTS of health related states and
events
