Identifying postpartum depression: Using key risk factors for early detection

Area of Science:

• Psychiatry
• Epidemiology
• Reproductive Health

Background:

• Personal and family psychiatric history are known risk factors for postpartum depression (PPD).
• The combined impact of these histories on PPD risk remains understudied.
• Understanding these combined effects is crucial for accurate risk assessment.

Purpose of the Study:

• To investigate the individual and combined effects of personal and family psychiatric history on the risk of mild/moderate and severe PPD.
• To determine the absolute and relative risks (RR) associated with these psychiatric histories.
• To identify key predictors for improved PPD risk stratification.

Main Methods:

• A large cohort study involving 142,064 childbirths with PPD screenings from 2015-2021.
• Data linkage with population registers for comprehensive psychiatric history assessment (hospital contacts, prescriptions).
• Poisson regression models were used to calculate adjusted absolute risks and RRs for PPD outcomes.

Main Results:

• Individuals with both personal and family psychiatric history exhibited the highest risk of mild/moderate PPD (absolute risk 11.7%, adjusted RR 2.35).
• Personal psychiatric history emerged as the most potent individual risk factor.
• A dose-response relationship was observed between the severity of psychiatric history and PPD risk.

Conclusions:

• A significant association exists between combined personal and family psychiatric history and increased PPD risk.
• Evaluating combinations of risk factors is essential for enhancing PPD risk assessment accuracy.
• These findings highlight the importance of a thorough family and personal psychiatric evaluation for pregnant individuals.
