To examine the separate and combined impacts of migraine and comorbidity on risks of severe maternal morbidity/mortality (SMM-M) and severe neonatal morbidity/mortality (SNM-M), highlighting the significance of these findings for healthcare practices.
Key Findings:
6.8% of participants had migraine and other chronic conditions, 3.2% had migraine alone, 45.7% had other chronic conditions alone, and 44.3% had neither.
Incidence of SMM-M was 1.6% (95% CI: X-Y) and SNM-M was 7.1% (95% CI: X-Y).
Risks of SMM-M and SNM-M were highest in those with both migraine and comorbidity (aRRSMM-M 1.60; aRRSNM-M 1.43).
Additive interaction was small for SMM-M (aAP 7.4%) and SNM-M (aAP 3.7%).
Interpretation:
Individuals with migraine and comorbidity face increased risks of severe maternal and neonatal complications, suggesting a need for targeted preconception and perinatal support to improve health outcomes.
Limitations:
The study is retrospective and relies on health administrative data, which may have limitations in capturing all relevant clinical details, potentially affecting the comprehensiveness of the findings.
Data on migraine and comorbidities were based on physician visits and may not reflect all cases, indicating a need for caution in generalizing results.
Conclusion:
Findings indicate that individuals with migraine and comorbid conditions could benefit from enhanced healthcare strategies to mitigate perinatal risks, underscoring the importance of further research in this area.
