Area of Science:

  • Nutritional Psychiatry
  • Women's Health
  • Perinatal Mental Health

Background:

  • Postnatal depression (PND) is a severe complication of childbirth with lasting effects on mothers and infants.
  • The precise causes and contributing factors of PND remain incompletely understood.
  • Dietary factors during pregnancy and postpartum may influence maternal mental health.

Purpose of the Study:

  • To review the role of selenium in postnatal depression.
  • To examine evidence linking selenium intake to maternal mental status postpartum.
  • To summarize potential biological mechanisms connecting selenium status and PND.

Main Methods:

  • Systematic review of interventional and observational studies.
  • Searches conducted in Medline (PubMed) and Google Scholar databases until December 2023.
  • Inclusion of studies on selenium intake (antenatal and postnatal) and postpartum mental health.

Main Results:

  • Limited studies exist, with potential methodological constraints.
  • Findings suggest a potential role for selenium in PND prevention and treatment.
  • Evidence indicates that optimizing selenium status may be beneficial.

Conclusions:

  • Selenium status may be a modifiable factor in PND.
  • Further longitudinal and interventional studies are required.
  • Clinical significance of selenium supplementation warrants further investigation.
