Question
In epidemiology, the study which first identify a group of individuals who have a specific disease, then attempt to ascertain commonalities in the exposure that group have experienced are referred to as
The correct answer is
Cohort study
Epidemiology: Core Principles of Cohort Studies
A cohort study is a fundamental epidemiological research design. It involves comparing groups based on their exposure status to specific factors.
Key characteristics of a cohort study include:
- Researchers identify distinct groups (cohorts) based on their exposure status to a potential cause or risk factor.
- These cohorts are then observed over time to measure and compare the incidence of a particular outcome, such as a disease.
The question describes identifying individuals with a disease and then examining their past exposures. This approach aligns with retrospective designs within cohort studies, where historical exposure data is analyzed for a defined population group experiencing a specific outcome to understand related factors.
