We investigated whether the characteristics of childbirth pain, as assessed by Short-form-McGill Pain Questionnaire-2 (SF-MPQ-2), were associated with postnatal anxiety and depressive disorders.Patients and Methods: Nulliparous parturients who received labor epidural analgesia (LEA) and delivered in our institution were invited to have a Mini-International Neuropsychiatric Interview (MINI) assessment following their 5– 9 weeks post-delivery follow-up phone survey of a larger study. Parturients’ demographics, pre-delivery questionnaires on pain and psychological vulnerabilities, LEA data, maternal and neonatal outcomes, postnatal follow-up survey on pain and psychological vulnerabilities, pain and breastfeeding were collected accordingly. The primary outcome was the binary variable (yes/no) of the presence of postnatal depression and/or anxiety disorders based on the post-delivery MINI assessment.Results: Among the 107 parturients who participated in the post-delivery MINI assessment, a total of 40 (42.5%) patients were found to have postnatal anxiety and depressive disorders. A greater pre-delivery SF-MPQ-2 neuropathic pain mean subscale score (adjusted odds ratio (OR) 1.32, 95% CI 1.00– 1.73, p=0.0482) and greater post-delivery Edinburgh Postnatal Depression Scale (EPDS) at 5– 9 weeks post-delivery (adjusted OR 1.30, 95% CI 1.13– 1.50, p=0.0002) were independently associated with the presence of postnatal anxiety and/or depressive disorders (receiver operating characteristic (ROC) = 0.7489).Conclusion: Patients with greater pre-delivery neuropathic pain and higher EPDS scores at 5– 9 weeks post-delivery are more likely to have postnatal depression and/or anxiety disorders, suggesting possible associations between pain and psychological vulnerability in the development of postnatal mental disorders.Keywords: neuropathic pain, postnatal depression, anxiety, pain vulnerability
