ABSTRACT
BACKGROUND:
Black women have a disproportionately higher burden of both preeclamptic pregnancy and stroke compared with White women, but virtually all existing evidence on this possible association has been generated from women of European ancestry.METHODS:
In the Black Women's Health Study, a prospective cohort of U.S. Black women who enrolled in 1995, 42,924 participants were parous and free of cardiovascular disease at baseline. Biennial questionnaires included questions on preeclampsia, gestational hypertension, and stroke. We sought the medical records for participants who reported a stroke, and we reviewed them blinded to reproductive history. Cox proportional-hazards models, with control for potential confounders, were used to estimate hazard ratios and 95% confidence intervals (CIs).RESULTS:
Over a median of 22 years of follow-up, there were 1555 incident strokes, including 310 among 4938 women with a history of hypertensive disorders of pregnancy (HDOP). The multivariable hazard ratio for stroke for women with any HDOP compared with those who had never experienced HDOP was 1.66 (95% CI, 1.46 to 1.89). Comparable hazard ratios were 1.53 (95% CI, 1.29 to 1.82) for preeclampsia and 1.81 (95% CI, 1.53 to 2.13) for gestational hypertension only. Associations were similar among women under age 55 years and those aged 55 years and older.CONCLUSIONS:
In this prospective study of Black women, a history of HDOP was associated with an estimated 66% increased long-term risk of stroke. This association may contribute to the disproportionately higher stroke incidence in Black women given the higher prevalence of HDOP in this population.
