Definition

  • Cohort studies represent a type of epidemiological approach to investigating the incidence and prevalence of disease across a fixed population group over time. Using this type of approach, researchers compare outcomes between a cohort, or group, of individuals who have a risk factor (e.g., smoking) believed to be associated with a disease (e.g., lung cancer) and a group without the factor (e.g., non-smokers).
