Objective: We sought to estimate the association between maternal seizure disorder and adverse pregnancy outcomes. Study Design: We performed a retrospective cohort study of singleton, nonanomalous pregnancies. Women with self-reported seizure disorder were compared to women without medical problems. The primary outcome was intrauterine growth restriction (IUGR) <10th percentile. Secondary outcomes included IUGR <5th percentile, stillbirth, preeclampsia, and preterm delivery. A sensitivity analysis was performed using women who reported using antiepileptics to estimate the impact of disease severity on pregnancy outcomes. Results: Of 47,118 women, 440 reported a seizure disorder. Women with seizure disorder were not at increased risk of IUGR <10th percentile (adjusted odds ratio, 1.11; 95% confidence interval, 0.82-1.50), IUGR <5th percentile, stillbirth, preeclampsia, or preterm delivery. The results were similar in the sensitivity analysis of women taking antiseizure medications. Conclusion: Our results suggest women with a seizure disorder are not at increased risk of IUGR, stillbirth, preeclampsia, or preterm delivery.
