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.

Participants are drawn randomly from the persons covered by the French National Health Insurance Fund (CNAM). Everyone with health insurance from CNAM as well as their dependents, is entitled to receive health examinations that include free extensive work-ups conducted in selected Health Screening Centers (HSCs). Randomly selected persons received an invitation to come to their HSC for inclusion in the CONSTANCES cohort. Inclusion in CONSTANCES took place over a 6-year period (2012-2019).
