Maternal preeclampsia and risk of bronchopulmonary dysplasia in preterm infants

Abstract

Introduction: To better understand whether preeclampsia (PE) increases the risk of bronchopulmonary dysplasia (BPD). Results: Of 753 infants alive at 36 wks, 138 (18.3%) were exposed to PE. BPD was not significantly related to exposure to PE either before (odds ratio (OR) 0.73; 95% confidence interval (CI) 0.50, 1.06) or after adjustment for confounding variables (adjusted OR 1.14; 95% CI 0.71, 1.81). If infants were selected by gestational age alone, there was no association (OR 1.05; 95% CI 0.63, 1.75). In contrast, selecting by birth weight alone, PE was associated with a significant reduction in BPD (OR 0.61, 95% CI 0.41, 0.91). However, this effect disappeared after adjustment for confo..
