    "abstract": "To explore the time trends and risk factors for pregnancy-related venous thromboembolism (VTE) in the Chinese population.\nA case-control study was conducted with 120\u2009652 pregnancies between Jan 2010 and June 2022 in Wuhan, China. Medical records from pregnant patients with VTE and patients without VTE were reviewed and analyzed.\nThere were 197 cases of VTE diagnosed during pregnancy or postpartum, with an overall incidence of 1.63 per 1000 pregnancies, and the incidence rate trend of VTE was increasing year by year and then declining. The incidence of deep venous thrombosis (DVT) was 1.24 per 1000 pregnancies (76.1%). Consistent with previous studies, most VTE occurred in the puerperium (1.05 per 1000 pregnancies, 64.5%). Significant risk factors included immobility, previous VTE, systemic infection, BMI over 30, and hypertensive disorders of pregnancy.\nPregnancy-related VTE is not uncommon in China which is consistent with current foreign reports, and the change in incidence trend may be related to greater physicians' understanding of VTE and effective preventive measures after the publication of Chinese guidelines.",
