Pathways between Risk/Protective Factors and Maternal Postnatal Depressive Symptoms: The ELFE Cohort

Area of Science:

• Perinatal mental health research
• Psychosocial factors in maternal well-being
• Epidemiology of postpartum depression

Background:

• Postnatal depressive symptoms (PNDS) affect many mothers, with numerous known risk factors.
• However, protective factors and the interplay between various exposures remain less understood.
• This study investigates the complex pathways influencing PNDS in a large general population sample.

Purpose of the Study:

• To explore the pathways linking maternal, infant, and parenthood vulnerabilities and risk/protective factors to PNDS.
• To identify key predictors of PNDS at two months postpartum.
• To inform targeted interventions for preventing and managing PNDS.

Main Methods:

• Utilized data from the French ELFE cohort (n=11,583) for a nationally representative sample.
• Collected data on risk/protective factors during maternity stay and at 2 months postpartum.
• Employed exploratory factor analysis and Structural Equation Modeling to analyze PNDS pathways using the Edinburgh Postnatal Depression Scale (EPDS).

Main Results:

• Lack of partner support, financial difficulties, prenatal distress, and difficult pregnancy experiences directly predicted PNDS severity.
• These factors also indirectly influenced PNDS through other vulnerabilities.
• Infant self-regulation issues, maternal difficulty understanding infant cues, and infant hospitalization were also associated with PNDS.

Conclusions:

• Antenatal perinatal support should focus on couple functioning, especially for women with psychiatric history and low socioeconomic status.
• Postnatal interventions should address infant and parenthood characteristics.
• Integrated, early, and targeted support is essential for maternal mental health.
