title: [Population-based cohorts. Example of the Gazel and Constances cohorts].
abstract: Population-based cohorts focus on the causes of diseases, especially multifactorial diseases. Some are very large, and prospectively collect personal, lifestyle, occupational and environmental data over several decades. All include biobanks. "Generalist" cohorts cover a large field of diseases and risk factors. Two examples are presented here The Gazel cohort was composed of 20,000 subjects aged 35-50 at enrolment andfollowed-up for 25 years, resulting in about 200 publications. The Constances cohort, created in 2012, aims to include a representative sample of 200,000 adults aged 18-69 at enrolment.
