Migraine as a risk factor for mixed symptoms of peripartum depression and anxiety in late pregnancy: A prospective cohort study

[摘要] Background: Migraine has been identified as a risk factor for peripartum depression. However, little is known about the contribution of anxiety to this association or potential changes throughout the peripartum period. Methods: In a sample of 4,831 women from the Biology, Affect, Stress, Imaging and Cognition cohort in Sweden, participants were asked about history of migraine prior to pregnancy. The participants completed the Edinburgh Postnatal Depression Scale (EPDS) at gestational weeks 17 and 32 and postpartum week 6. Multinomial logistic regression analyses were used to assess associations between migraine and symptoms of depression, anxiety or mixed depression and anxiety, while adjusting for potential confounders. Results: In crude estimates, migraine was associated with separate and mixed symptoms of depression and anxiety at most time points. After adjustments, migraine was associated with anxiety at week 17 (adjusted odds ratio: 1.69; 95% confidence interval: 1.11-2.54) and with mixed depression and anxiety at week 32 (adjusted odds ratio: 1.45; 95% confidence interval: 1.06-1.99). None of the other associations remained statistically significant after adjustments. Limitations: Migraine history was self-reported. Symptoms of depression and anxiety were based on the screening tool EPDS and not on clinical diagnoses. Conclusions: The results demonstrate that migraine may be a risk factor for anxiety in mid-pregnancy and mixed symptoms of peripartum depression and anxiety in late pregnancy. Inflammatory and hormonal factors may underlie the association between migraine, depression and anxiety across the peripartum period.
