Objectives To describe outcomes associated with hypertensive disorders during pregnancy in Brazil. Introduction Hypertensive disorders represent the major maternal morbidity in middle-income countries, which can contribute to both maternal and neonatal adverse outcomes. “Birth in Brazil” study was the first national representative survey, offering the opportunity of evaluate this relationship in the country. Methods Birth in Brazil is a national hospital-based survey of postnatal women and newborns conducted between February 2011 and October 2012. We obtained data from hospital medical records and interviews of 23,894 women and their newborns in 266 hospitals with ⩾500 deliveries per year. This sample was stratified by Brazil’s five macro-regions, location (state capital or elsewhere) and type of hospital (private, public or mixed). We compared maternal and neonatal outcomes of women with and without hypertensive disorders using Chi-square Pearson test. Results The prevalence of hypertensive disorders during pregnancy was 12.5% ( n = 2999). Considering all women with hypertensive disorders, 63.7% ( n = 1910) had pre-eclampsia/gestational hypertension, 20.5% ( n = 614) superimposed pre-eclampsia, 11.4% ( n = 342) chronic hypertension and 0.4% ( n = 133) eclampsia. Women with hypertension during pregnancy were older (17.9% vs. 9.4% with ⩾35 years, p 11 years of schooling, p = 0.02) than women without hypertensive disorders. Also, women with hypertension during pregnancy had more previous cesarean (26.2% vs. 20.7%, p p = 0.002) and more pre-gestational diabetes (4.0% vs. 0.6%, p p p p p p p p Conclusions The prevalence of hypertensive disorders in Brazil seems to be slightly higher than other countries and had significant impact on maternal and neonatal outcomes. Public policies should emphasize the proper prenatal and intrapartum care in women with hypertension during pregnancy, avoiding delays in care. |
