Cohorte des consultants des Centres d'examens de santé

The objective of the CONSTANCES project is to set-up a large population-based cohort to contribute to the development of epidemiologic research and to provide useful public health information. The aging-related scientific objectives in CONSTANCES involve the study of the role of various types of risk factors throughout the life course. Another objective is to document the determinants of health most frequently encountered or suspected in chronic age-related diseases.
