This is a population-based case-control study in Germany.
Cases are women who are between 15 and 49 years old with a diagnosis of venous thromboembolism (VTE). The VTE is diagnosed in Germany between January 2002 und December 2007.
Controls are women who are between 15 and 49 years old without a VTE diagnosis. About 4 controls matched by year of birth and region will be allocated to each case.
Both cases and controls will receive a similar self-administered questionnaire except of some case-specific questions which are not applicable for the controls.
Study participants will be asked for their informed consent. Data confidentiality will be ensured by the Berlin Center for Epidemiology and Health Research.
