BACKGROUND: @entity1211 ( @entity1211 ) is a major contributor of maternal morbidity and mortality. Whether maternal race/ethnicity is associated with the risk of postpartum @entity1211 remains unclear. METHODS AND RESULTS: We conducted a population-based, case-control study in Washington State, from 1987 through 2011. Cases comprised all @entity1 with selected ICD-9-CM codes for hospitalized @entity1211 within 3 months post-delivery. Controls were randomly selected postpartum @entity1 who did not experience a @entity1211 . Characteristics of @entity1 and their deliveries were abstracted from birth certificates. Using logistic regression models, we compared the risk of postpartum @entity1211 in Black, Asian, and Hispanic @entity1 with that in non-Hispanic White @entity1 , after adjustment for maternal characteristics (age, BMI, parity, education), pregnancy complications, and delivery methods. RESULTS: Our study comprised 688 cases and 10,246 controls. Among controls, the mean age and BMI were 27.5 years and 26.3 kg/m(2) , respectively. Compared with White @entity1 , Black and Asian @entity1 had a greater and lower risk of postpartum @entity1211 , respectively (adjusted OR 1.50, 95%CI 1.10-2.04 and OR 0.67, 95%CI 0.48-0.94). A lower risk was present in Hispanic @entity1 (adjusted OR 0.80, 95%CI 0.61-1.06), but was not statistically significant. In subgroups analyses, we observed an increased risk for Black compared with White @entity1 among @entity1 who delivered via cesarean section (OR 2.03, 95%CI 1.34-3.07) but not among vaginal deliveries (OR 1.03, 95%CI 0.61-1.74). CONCLUSIONS: Maternal race/ethnicity is associated with the risk of postpartum @entity1211 , independently of other risk factors, and should be considered when assessing the use of thromboprophylaxis after delivery.
