title: Obstetrical and perinatal outcomes among women with gestational hypertension, mild preeclampsia, and mild chronic hypertension.
abstract: OBJECTIVE
  The purpose of this study was to compare maternal and neonatal outcomes of women with gestational hypertension (GHTN), mild chronic hypertension (CHTN), and mild preeclampsia at delivery.
  
  
  METHODS
  A multicenter database that contained 228,668 deliveries was used to extract data on gravid women with GHTN, preeclampsia, and CHTN and on women without hypertensive disease (control group). Univariate and multivariate logistic regression analyses were performed.
  
  
  RESULTS
  There were 4918 women with GHTN, 5274 women with preeclampsia, 2531 women with CHTN, and 15,221 control subjects. Women with GHTN had the greatest risk for blood transfusion (adjusted odds ratio [aOR], 4.6; 95% confidence interval [CI], 3.4-6.3), intensive care unit admission (aOR, 25.7; 95% CI, 9.8-67.3), and lowest risk for stillbirth (aOR, 0.1; 95% CI, 0.04-0.4); women with preeclampsia had the greatest risk for postpartum hypertension (aOR, 9.6; 95% CI, 7.2-12.9). Neonates with GHTN had the greatest risk for ventilator requirements (aOR, 7.5; 95% CI, 4.6-12.4).
  
  
  CONCLUSIONS
  Women with gestational hypertension and their neonates had significant risks for morbidity, compared with women with mild chronic hypertension and those with mild preeclampsia.
