Cohort Study

C-SURF is a cohort study directed by the Centre hospitalier universitaire vaudois (CHUV) in Lausanne and the Social and Preventive Medicine Institute at Zürich University in Switzerland. It started in 2010 and is still running today, thanks to the financial support of the Swiss National Research Foundation.

   A cohort study seeks to follow the progression of a group's behaviour by involving members recurrently in the long run (18 months in the first phase, then 5 years or beyond, according to funding).

What is it about and who participates?

All young men at the army recruitment centers in Lausanne (VD), Windisch (AG) and Mels (SG), Switzerland, were invited to participate in this cohort study. It is about:

• their socioprofessional and family background
• their lifestyle and personality
• their consumption of tobacco, alcohol, cannabis and other drugs
• their gambling and gaming activities and use of internet
• their sexuality
• their physical and mental health
• and their knowledge about other health-related aspects
