Abstract
Background
Postpartum depression is one of the most commonly experienced psychological disorders for women after childbirth, usually occurring within one year. This study aimed to clarify whether women with painless delivery, including epidural analgesia, spinal-epidural analgesia, and paracervical block, had a decreased risk of postpartum depression after giving birth in Japan.
Methods
The Japan Environment and Children’s Study (JECS) was a prospective cohort study that enrolled registered fetal records (n = 104,065) in 15 regions nationwide in Japan. Binomial logistic regression analyses were performed to calculate the adjusted odd ratios (aORs) for the association between mode of delivery with or without analgesia and postpartum depression at one-, six- and twelve-months after childbirth.
Results
At six months after childbirth, painless vaginal delivery was associated with a higher risk of postpartum depression (aOR: 1.218, 95% confidence interval: 1.067–1.391), compared with vaginal delivery without analgesia or cesarean section. Nevertheless, the risk disappeared one year after delivery. Among the pregnant women who requested painless delivery, 5.1% had a positive Kessler-6 scale (K6) score for depression before the first trimester (p < 0.0001), which was significantly higher than the proportions in the vaginal delivery without analgesia (3.5%) and cesarean delivery (3.5%) groups.
Conclusions
Our data suggested that the risk of postpartum depression at six months after childbirth tended to be increased after painless vaginal delivery, compared with vaginal delivery without analgesia or cesarean section. Requests for painless delivery continue to be relatively uncommon in Japan, and women who make such requests might be more likely to experience postpartum depressive symptoms because of underlying personality characteristics, including a tendency to worry.
