(HealthDay News) — After adjustment for sociodemographic and cardiovascular risk factors, nativity-related disparities in preeclampsia persist among non-Hispanic Black women but not among Hispanic and non-Hispanic White women, according to a study published online in JAMA Network Open.
Ellen Boakye, MD, MPH, from the Johns Hopkins School of Medicine in Baltimore, and colleagues examined differences in cardiovascular risk factors and preeclampsia prevalence by race and ethnicity, nativity, and duration of U.S. residence in a racially diverse cohort of women who had singleton deliveries at the Boston Medical Center from Oct. 1, 1998, to Feb. 15, 2016. The study sample included 6096 women (2400 Hispanic; 2699 non-Hispanic Black; and 997 non-Hispanic White).
The researchers found that non-Hispanic Black women had the highest prevalence of chronic hypertension, obesity, and preeclampsia compared with Hispanic and non-Hispanic White women. US-born women of all 3 racial and ethnic groups had a higher prevalence of obesity, smoking, and severe stress compared with their counterparts born outside the United States. Birth status outside the United States (adjusted odds ratio, 0.74; 95 percent confidence interval, 0.55 to 1.00) and shorter duration of U.S. residence (adjusted odds ratio, 0.62; 95 percent confidence interval, 0.41 to 0.93) were associated with lower odds of preeclampsia among non-Hispanic Black women, but not among Hispanic and non-Hispanic White women, after adjustment for sociodemographic and cardiovascular risk factors.
“The findings of this cross-sectional study suggest that factors contributing to nativity-related disparities in preeclampsia may differ by race and ethnicity,” the authors write.
