Prevalence and associated risk factors of postpartum depression in India: A comprehensive review

Postpartum depression (PPD) is a psychological illness that affects women following delivery. According to the fourth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-IV-TR), PPD is a serious form of depression that begins four weeks following birth and continues for one year. Pregnancy and the period after delivery can be hazardous for women. Mothers undergo significant biological, emotional, financial, and societal changes during this time. Some women are predisposed to mental health disorders such as melancholy and worry. Many postpartum women do not acknowledge the seriousness of their condition, and many depressed mothers go untreated. Untreated PPD is harmful to both the mother and the newborn. The exact cause of PPD is unclear; however, hormonal fluctuations during pregnancy and childbirth, genetic susceptibility, birth trauma as well as psychosocial and demographic factors may serve as potential risk factors. The objective of this study is to determine the prevalence and risk factors of PPD in India. The review evaluates English language literature on PPD using Scopus, PubMed, and Google Scholar databases searched electronically between 2000 and 2022. The keywords "postpartum depression," or "postnatal depression," and "prevalence," and "causes," and "risk factors," or "predisposing factors," or "predictive factors" were used to search the database. The prevalence of PPD varies in different geographical regions and study settings. In India, the overall prevalence of PPD is 22%. However, the greatest prevalence was in the southern regions (26%; 95% confidence interval [CI]: 19-32) and the lowest in the northern regions (15%; 95% CI: 10-21). This study outlines the burden of PPD in India. Comprehensive intervention programs should be implemented to address the disease at a national level. The national authorities should incorporate PPD screening in the National Mental Health Program and emphasize health promotion activities.
