The main objectives are to:
 | build up, maintain and yearly extend the first nationwide cohort |
| to offer other cohorts and clinical databases expertise in record linkage and information on socio-economic status |
This will be achieved by:
| extending follow-up by periodically updating the database with the latest available mortality and migration files, using automated record linkage procedures |
| developing measures of socio-economic status that are tailored to the Swiss context |
| developing and implementing procedures that allow the creation of well defined subcohorts to address specific research questions |
| developing and implementing procedures to swiftly identify deaths among participants lost to follow up in other prospective cohort studies |
