title: Increased risk of adverse pregnancy outcomes for women with migraines: a nationwide population-based study.
abstract: Using a 3-year nationwide population-based database, this study aims to examine the risk of adverse pregnancy outcomes in women with migraines, including low birthweight (LBW), preterm birth, infants born small for gestational age, Caesarean section (CS) and pre-eclampsia. We identified a total of 4911 women with migraines who gave birth from 2001 to 2003, together with 24,555 matched women as a comparison cohort. Multivariate logistic regression analyses showed that after adjusting for potential confounders, the odds ratios were 1.16 [95% confidence intervals (CI) = 1.03-1.31, P = 0.014] for LBW, 1.24 (95% CI = 1.13-1.39, P < 0.001) for preterm births, 1.16 (95% CI = 1.07-1.24, P < 0.001) for CS and 1.34 (95% CI = 1.02-1.77, P = 0.027) for pre-eclampsia for women with migraines compared with unaffected mothers. We conclude that women with migraines were at increased risk of having LBW, preterm babies, pre-eclampsia and delivery by CS, compared with unaffected mothers.
