Women with migraine and their offspring have greater risks of adverse pregnancy outcomes than women without migraine, a new study found. Researchers investigated the associations between maternal migraine and risks of adverse pregnancy outcomes in the mother, and birth, neonatal and postnatal outcomes in the offspring. They evaluated a cohort of pregnancies among women with migraine and an age- and conception year-matched comparison cohort of pregnancies among women without migraine. They found:
- 22,841 pregnancies among women with migraine and 228,324 matched pregnancies among women without pregnancies were identified.
- Migraine was associated with an increased risk of pregnancy-associated hypertension disorders and miscarriage.
- Migraine was also associated with an increased prevalence of low birth weight, preterm birth, and cesarean delivery, but not of small for gestational age offspring and birth defects.
- Offspring prenatally exposed to maternal migraine had elevated risk of several outcomes in the neonatal and postnatal period.
