In a cohort study, these individuals are followed and assessed over time in order to describe and understand the evolution of their health and living conditions. These types of epidemiological studies are essential tools for Public Health research.
Participants in these cohorts regularly provide information through questionnaires, medical examinations or interviews.
The information obtained through cohort studies provides answers to numerous scientific questions and is useful for planning health promotion, health protection and disease prevention measures.
The Instituto de Saúde Pública da Universidade do Porto (ISPUP) manages the organisation of 10 research cohorts.
