This Mental Elf blog post is about a recent systematic review and meta-regression of the prevalence and incidence of perinatal depression. The blogger concludes that the systematic review estimated that the prevalence of perinatal depression is approximately 12%. Estimates of prevalence are important for increasing awareness of depression during pregnancy and the postnatal period, and informing the allocation of health resources. In particular, this study highlights that depression is equally prevalent during pregnancy as in the postnatal period, and that there is a higher prevalence of perinatal depression in low and middle income countries than in high income countries.
