Abstract
BACKGROUND: Depression is a common and serious complication in new mothers. We investigated the hypothesis that neuraxial labor analgesia is associated with a decreased risk of postpartum depression. METHODS: In this multicenter prospective cohort study with propensity score matching, 599 nulliparous women with single term cephalic pregnancy who planned vaginal delivery were enrolled and self-selected neuraxial analgesia or not. The primary outcome was 6-week postpartum depression assessed with the Chinese version Edinburgh Postnatal Depression Scale; a score of ≥10 was set as the threshold of postpartum depression. Logistic regression models were established to assess the association between neuraxial labor analgesia and postpartum depression. RESULTS: Of the 577 parturients who completed the study, 417 (72.3%) received neuraxial analgesia and 160 (27.7%) did not. After propensity score matching, 433 parturients were included in the analysis; of whom, 279 (64.4%) received neuraxial analgesia and 154 (35.6%) did not. The incidence of postpartum depression was lower in parturients with neuraxial analgesia than in those without (14.9% [62/417] vs. 23.8% [38/160], P=0.012 before matching; 13.3% [37/279] vs. 23.4% [36/154], P=0.007 after matching). After adjustment for confounding factors, neuraxial analgesia was associated with decreased odds of postpartum depression (odds ratio [OR] 0.50, 95% CI 0.28-0.88, P=0.015 before matching; OR 0.40, 95% CI 0.21-0.77, P=0.006 after matching). LIMITATIONS: As an observational study, unidentified confounders might influence the results. CONCLUSIONS: In nulliparae with single term cephalic pregnancy preparing to give vaginal delivery neuraxial analgesia during labor was associated with a decreased risk of 6-week postpartum depression.
