| prospective s. |
a longitudinal epidemiologic study in which the groups of individuals (cohorts) are selected on the basis of factors that are to be examined for their effects on outcomes, e.g., the effect of exposure to a specific risk factor on the eventual development of a particular disease, and are then followed over a period of time to determine the incidence rates of the outcomes in question in relation to the original factors. Called also cohort s. “Prospective” usually implies a cohort selected in the present and followed into the future, but the cohort method can also be applied to existing longitudinal historical data, such as insurance or medical records: a cohort is identified and classified as to exposure to some factor at some date in the past and followed up to the present to determine incidence rates of the outcome. This is called a historical prospective study, prospective study of past data, or retrospective cohort study. Cf. retrospective s.
