Impact of Paternal Postpartum Depression on Maternal and Infant Health: A Narrative Review of the Literature

Postpartum depression (PPD) has been widely studied, assessed, and promptly intervened in new mothers. However, paternal postpartum depression gained attention not long ago. Postpartum depression in men could present over one year following the birth of the child, frequently presenting with symptoms like irritability, low mood, sleep disturbances, changes in appetite, fatigue, and loss of interest in everyday activities; amongst other symptoms of Major Depressive Disorder which may hinder them from taking care of themselves and the baby. Paternal PPD significantly impacts partner relationships causing maternal PPD, poor infant bonding, and therefore, affecting overall child development. The following narrative review is based on a literature search of articles published on paternal postnatal depression. The primary emphasis of this review has been to provide an overview of the current comprehension of paternal postpartum depression regarding prevalence, global incidence, and risk factors and to explore potential diagnostic tools for assessment and interventional strategies to treat this condition. Interestingly, pandemic-related stressors have been positively attributed to an increase in PPD prevalence post-pandemic. While more research is being conducted on this subject, research on the measurement characteristics of the diagnostic tools is highly recommended to implement well-defined criteria for early diagnosis of paternal PPD. The significant adverse consequences of PPD for not just the new mother, but also the infants, necessitate proper and timely diagnosis of PPD. Despite its severity, there have been no specific treatment modalities.
