Abstract
Objective: To verify the occurrence of preeclampsia/eclampsia (PE/E) or gestational hypertension (GH) in first-degree relatives of Brazilian pregnant women. Methods: A total of 485 women were enrolled in the study, and 226 were selected (75 with PE/E, 49 with GH, and 102 women with normal pregnancies). Statistical analysis was performed using Fisher's exact test. Results: The frequency of families with mothers and/or sisters with PE/E was higher among the PE/E group compared to the GH and the control groups, and was statistically significant (p < 0.05). Conclusion: Women with PE/E have more female first-degree relatives with PE/E as observed in a Brazilian population.
