Purpose: Postnatal depression (PND) is associated with maternal morbidity and socioeconomic burden. Recent studies have shown an association between pain catastrophizing, increased labor pain, and subsequent adverse postnatal adjustment; however, little is known on its role in PND development. We aimed to investigate the association between pain catastrophizing and probable PND.
Methods: Parturients planning to undergo epidural labor analgesia were recruited. Predelivery questionnaires, including the Pain Catastrophizing Scale (PCS) and Edinburgh Postnatal Depression Scale (EPDS), were administered during early labor. A phone survey at 5– 9 weeks postdelivery was conducted to determine postdelivery EPDS and Spielberger’s State–Trait–Anxiety Inventory scores. The primary outcome was a binary variable of postdelivery EPDS with cutoff of ≥ 10, whereas the secondary outcome was a continuous variable on increases in EPDS score.
Results: Probable PND (EPDS ≥ 10) occurred in 10.5% (95% CI 8.0%– 13.5%, 55 of 525) of women who underwent epidural labor analgesia. We found that high pain catastrophizing (PCS ≥ 25) was associated with increased postdelivery EPDS scores (adjusted β estimate 0.36, 95% CI 0.15– 0.57; p=0.0008), but did not meet significance for increased risk of probable PND (p=0.1770). Additionally, presence of breakthrough pain during epidural analgesia (adjusted β estimate 0.24, 95% CI 0.02– 0.46; p=0.0306) and lower BMI at term (adjusted β estimate − 0.04, 95% CI − 0.07 to − 0.01; p=0.0055) were associated with increased postdelivery EPDS scores.
Conclusion: No significant association was found between high pain catastrophizing and probable PND; however, high predelivery pain catastrophizing, presence of breakthrough pain during epidural analgesia, and lower BMI at term were associated with increased postdelivery EPDS scores. Further research will be needed to validate this association in the context of the risk of PND development.
