Intimate Partner Violence as a Risk Factor for Venous Thromboembolism in Women

The frequency of violence against women, or intimate partner violence (IPV) is more and more underlined and recognized as a cofactor favoring certain somatic and psychic pathologies. However, its incidence in patients with venous thromboembolism (VTE) is unknown and its status as a risk factor is still elusive and ambiguous.

Investigators therefore conducted a matched case-control study consisting of women taking combined oral contraceptives (COC) who were investigated and followed up between 2010 and 2020.

The cases are the patients investigated for their first venous thromboembolic event, The controls were women free of thrombosis who had regular gynecological checkups. Case-control pairs were matched on region of residence, age (+/- 2 years), duration of COC intake (+/- 4 months), COC type (2nd, 3rd or 4th generation).
