Risk factors for early postpartum depressive symptoms

Area of Science:

• Reproductive Psychiatry
• Perinatal Mental Health
• Obstetrics and Gynecology

Background:

• Postpartum depressive disorders are prevalent, with symptoms often emerging within two weeks after childbirth.
• Limited data exists on hormone-related risk factors for very early postpartum depressive symptoms, hindering the identification of severe postpartum illness.
• Understanding these early indicators is vital for timely intervention and management.

Purpose of the Study:

• To investigate the association between a history of psychiatric symptoms with potential hormonal etiology and the occurrence of very early postpartum depressive symptoms.
• To identify key risk factors contributing to the onset of depressive symptoms in the immediate postpartum period.

Main Methods:

• A cohort of 1,800 women in a general hospital maternity ward were assessed within three days postpartum.
• Data collected via self-reported questionnaires for risk factors and the Edinburgh Postnatal Depression Scale (EPDS) for current mood symptoms.
• Statistical analyses were performed to determine associations between identified risk factors and postpartum depressive symptoms.

Main Results:

• The incidence of postpartum depressive symptoms (EPDS ≥10) was 6.8% (88/1,286 women).
• Significant risk factors identified include a history of mental illness, past postpartum depression, premenstrual dysphoric disorder (PMDD), and mood symptoms during the third trimester.
• These findings highlight specific vulnerabilities for early postpartum mood disturbances.

Conclusions:

• A history of depression is confirmed as a risk factor for early postpartum mood symptoms.
• Hormone-related risk factors, such as PMDD and third-trimester mood symptoms, are associated with early postpartum mood disturbances.
• Assessing these risk factors and mood immediately postpartum is important, as early symptoms may predict subsequent postpartum depression (PPD).
