  • Title: Migraine and preterm birth.
    Author: Blair EM, Nelson KB.
    Journal: J Perinatol; 2011 Jun; 31(6):434-9. PubMed ID: 21183924.
    Abstract:
    OBJECTIVE: To investigate whether maternal migraine was associated with preterm birth. STUDY DESIGN: Case-control sample within a population-based study of risk factors for cerebral palsy (CP). Infants without CP were matched for gestational age with those with CP. Maternal migraine was self-identified at first prenatal visit, most in the first trimester. RESULT: Infants without CP born to women with migraine had a higher rate of preterm birth (odds ratio (OR)=3.5, 95% confidence interval (CI) 1.5, 8.5), as did infants who died in the perinatal period (OR=7.3, 95% CI 0.98, 54), the difference marginal for nominal statistical significance. In all outcome groups, infants of women with migraine had a higher observed rate of suboptimal intrauterine growth. In term infants, the rate of maternal migraine was higher in those with CP than in controls (OR=2.18, 95% CI 0.92, 5.25). Pre-eclampsia was reported more frequently in women with migraine who gave birth to a child with CP or a perinatal death, particularly in those born preterm; OR=5.1 (1.3, 20) and OR=2.9 (1.1, 7.6), respectively, but not in women giving birth to a control whether term or preterm. CONCLUSION: Maternal migraine, as self-reported early in pregnancy, was associated with preterm birth in survivors without CP and in infants who died in the perinatal period. The combination of maternal migraine and pre-eclampsia was associated with CP and perinatal death. The association of maternal migraine with outcomes of pregnancy warrants further study.
