Cohort studies constitute one of the basic types of designs in epidemiologic research. The key element of cohort studies is time. Specifically, a cohort (i.e. group of individuals) who at enrolment is free from the disease (i.e. outcome) whose natural history is of interest and who have heterogeneous profiles of putative risk factors (whose simplest form is as exposed or unexposed) is followed over time. The central aim of this type of study is to determine the occurrence of an event of interest (e.g. disease, death) and to characterize its heterogeneity according to constellations of risk factors.
