Abstract

Introduction: In recent years, clinical studies have shown that perinatal pain could increase the risk of postpartum depression, while such a conclusion appears controversial. Therefore, we conducted this systematic review and meta-analysis to explore the association between perinatal pain and postpartum depression, and to evaluate the effectiveness of epidural labor analgesia in reducing the risk of postpartum depression.

Methods: PubMed, Web of Science, Embase and Cochrane Library were searched from inception to Jan 30th, 2022. The effect size of the meta-analysis was calculated using odds ratio and 95 % confidence interval. Statistical analysis was performed using Stata 15.0 software.

Results: There were 19 studies included with a total of 96,378 patients. Among the included studies, 10 investigated the association between perinatal pain and the risk of postpartum depression, and 9 reported that between labor analgesia and the risk of postpartum depression. The results of meta-analysis showed that perinatal pain increased the risk of postpartum depression [OR = 1.43, 95% CI (1.23, 1.67), p<0.05], and epidural analgesia could reduce the risk of postpartum depression [OR = 0.42, 95% CI (0.33, 0.55), p < 0.05].

Limitations: Source of heterogeneity in the association between perinatal pain and PPD could not be identified due to the limitations of the original studies. There were mainly cohort studies included in the assessment for effectiveness of epidural analgesia in reducing the incidence of postpartum pain. Therefore, we look forward to more RCTs to confirm our results.

Conclusion: Perinatal pain is one of the risk factors for postpartum depression, and epidural analgesia could reduce the risk of PPD. This result might provide guidance for clinical practice. However, psychological health counseling should be combined with epidural analgesia for perinatal pain to reduce the risk of PPD.
