In 2009, when it was launched, the Tempo cohort consisted of 1,103 people between the ages of 22 and 35 who had participated in a study on children and adolescents’ health between 1991 and 1999: “Les Enfants de Gazel”.

In 2011, Tempo cohort expanded to:

– include young people aged 18-25 years who have specific health situations and life situations
– increase the number of participants to study infrequent health problems.

In 2011 1,214 people were interviewed. In 2015, 783 people participated in the study and 533 participants returned a saliva collection kit. Saliva samples allow us to identify genetic markers that are associated with addictive behaviours (tobacco, alcohol and cannabis/CBD) in relation to characteristics of people’s lives.

In total 526 respondents responded at least three times, and 334 at least four times, giving us the opportunity to examine health trajectories over time.

Participants in the Tempo cohort were asked about their health, the situations they encountered in their daily lives, their work and family experiences.
