Objective: To evaluate perinatal outcomes in nulliparous women undergoing induction of labor for gestational hypertension at term. Study design: Retrospective cohort study of nulliparous women with gestational hypertension undergoing induction of labor ≥37 weeks. Mode of delivery and perinatal outcomes were compared for women who delivered at 370–6/7, 380–6/7, and ≥390/7weeks gestation. Results: The cohort included 320 women: 67 (21%) at 370–6/7, 76 (24%) at 380–6/7, and 177 (55%) at ≥390/7. There was no increase in cesarean delivery (CD) in women delivering earlier, with 26.9% (370–6/7), 19.7% (380–6/7) and 29.9% (≥390/7) requiring CD (pvalues = 0.39). Compared to ≥39 weeks, composite maternal morbidity was lowest in women delivering at 380–6/7(adjusted odds ratio [aOR] 0.45, 95% confidence interval (CI) 0.24–0.84). Composite neonatal morbidity was similar among the groups. When compared to women delivering at ≥390/7weeks, women delivered at 380–6/7were less likely to experience any adverse maternal or neonatal outcome (aOR 0.50, 95% CI 0.28–0.90). Conclusions: Compared to induction of labor at ≥39 weeks, early term induction of labor was not associated with an increased risk of CD in nulliparous women with gestational hypertension.
