Among one of the most common sources of morbidity associated with childbirth, postpartum depression is a major global public health issue. PPD varies in prevalence worldwide. However, research has found that globally postpartum depression is found to be approximately 17.7% prevalence when analyzing data from low- to high-income countries. Across various nations, the prevalence of PPD varied even within nations with similar wealth status. However, between the nations, a predictor for higher postpartum depression rates was found to be wealth disparities within the nations. Those who experience this wealth disparity live at a dramatically different level of material standards than the other’s in their society, even if objectively they are not low income. If a mother has experienced postpartum episodes previously, her risk of experiencing postpartum depression with psychosis is higher than those who have had no previous episodes.
