Cohort study

Similar term(s): prospective study.

A type of epidemiological study which observes a large number of individuals in a population over a period of time.

It compares individuals who are exposed for instance to a certain chemical to others without the exposure or with a different level of exposure. These two groups are called cohorts and are followed over time to determine the differences in the health outcomes between the exposure subjects.
