Racial/ethnic differences in pregnancy-related hypertensive disease in nulliparous women.

Abstract

Non-Hispanic Black women had higher odds of entering pregnancy with chronic hypertension (adjusted odds ratio (AOR) = 1.43, 95% confidence interval (CI) 1.11-1.84) and had higher odds of developing mild (AOR = 1.26, 95% Cl 1.10-1.45), severe (AOR = 1.31, 95% Cl 1.10-1.57) or superimposed preeclampsia (AOR = 1.98, 95% ClI 1.40-2.80) compared to non-Hispanic White women. Hispanic women and Asian/Pacific Islanders had higher odds of remaining normotensive (AOR = 1.22, 95% CI 1.12-1.33 and AOR=1.55, 95% CI 1.31-1.84, respectively). Conclusions: Odds for specific gestational hypertensive diseases varied by race/ethnicity among women during their first pregnancy. Non-Hispanic Black women experienced more severe disease, while Hispanic women and Asian/Pacific Islanders had an overall decreased risk compared to non-Hispanic Whites. Patterns of racial/ethnic variation associated with hypertensive diseases during pregnancy were similar to racial/ethnic associations reported for adult-onset cardiovascular disease, suggesting that there may be common pathways and shared risk factors.
