Prevention of Postpartum Depression
Screen all pregnant and postpartum women for depression and anxiety using validated tools, and immediately initiate evidence-based psychotherapy (interpersonal therapy or CBT) for those with identified risk factors or mild symptoms, while reserving antidepressants for moderate-to-severe cases or those with prior severe depression history. 1, 2, 3
Universal Screening Strategy
Screen all pregnant women for depression regardless of risk factors using validated self-report measures such as the Edinburgh Postnatal Depression Scale (EPDS), Patient Health Questionnaire, or Hospital Anxiety and Depression Scale. 1, 3
The EPDS is the most robustly validated screening tool with demonstrated sufficient psychometric properties across over 60 language translations. 3
Screen at multiple time points throughout pregnancy and postpartum, as depression prevalence actually increases over time—from 12.9% at 8 weeks to 17.4% at 12 weeks, and continuing to rise to 20% at 7-12 months postpartum. 4
Do not assume women who screen negative early are protected—nearly 3 in 5 women (57.4%) with depression at 9-10 months postpartum did not report symptoms at 2-6 months. 4
Screen for both depression and anxiety simultaneously, as postpartum anxiety affects 16-24.4% of women and frequently co-occurs with depression, negatively impacting treatment outcomes if left unaddressed. 3, 5, 6
Identify High-Risk Women
The strongest risk factors requiring heightened surveillance and early intervention include: 1, 7, 8, 9
History of depression or anxiety disorder—this is the single strongest predictor, especially if symptoms are active during pregnancy. 7, 9
Previous postpartum depression episode. 1
Severe life events, chronic stress, or increased life stressors. 1, 8
Poor relationship quality, single/unpartnered status, or decreased social support from partner or mother. 1
Prenatal anxiety, child-care stress, or unintended pregnancy. 1
Lower socioeconomic status, unemployment, or undereducation. 1
Foreign language spoken at home, nonwhite race/ethnicity. 1, 8
Preterm birth, difficult infant temperament, or excessive infant crying. 1, 8
Preventive Interventions for High-Risk Women
Psychosocial Interventions (First-Line Prevention)
Initiate interpersonal psychotherapy (IPT) immediately for women with identified risk factors, focusing on navigating role transitions and resolving conflicts with close others—this has shown moderate success in reducing PPD. 2
Cognitive-behavioral therapy (CBT) is equally effective and can be used based on patient preference and availability. 2
Implement targeted interventions to increase social support from significant others, particularly partner and family support, which are consistently protective factors against postpartum depression. 2
Ensure adequate partner support, address potential stressors and chronic strain, and improve relationship quality and satisfaction. 2
Encourage exercise and social support seeking for all pregnant women. 1, 2
Consider mindfulness-based interventions to improve self-compassion and parental self-efficacy. 2
Pharmacological Prevention (For Specific High-Risk Cases)
Women with severe depression history who previously relapsed when discontinuing antidepressants should continue antidepressant use during pregnancy rather than attempting discontinuation. 1
Women with history of severe suicide attempts or severe depression who previously achieved symptom reduction with antidepressants may need to continue treatment throughout pregnancy. 1
When antidepressants are needed during pregnancy or breastfeeding, sertraline is the preferred first-line agent due to low breast milk concentrations, with paroxetine as the alternative option. 2, 3
Consider CBT or other evidence-based counseling interventions first when managing depression in pregnant or breastfeeding women, given potential harms to the fetus and newborn from certain pharmacologic agents. 1
Monitoring and Early Intervention Timeline
For women with mild depression of recent onset (≤2 weeks), monitor symptoms closely and encourage exercise and social support rather than immediately starting medication. 2
If depressive symptoms persist beyond 2 weeks from initial diagnosis or worsen during the monitoring period, initiate evidence-based treatment immediately—do not delay. 2, 3
The first 4-6 weeks postpartum represent the highest-risk period for symptom onset, though depression can develop at any point up to one year postpartum. 4
Schedule screening at 8-12 weeks postpartum when peak prevalence occurs (17.4%), and again at 7-12 months when rates continue to increase. 4
Systems-Level Prevention
Ensure screening is implemented with adequate systems in place for accurate diagnosis, effective treatment, and appropriate follow-up, as depression is the second leading cause of maternal mortality in the United States. 3
Consider collaborative care models using case managers to link primary care providers, patients, and mental health specialists as part of multicomponent health care system-level interventions. 1
Telemental health interventions may be superior to treatment as usual for reducing postpartum depression symptoms, offering increased accessibility with mean EPDS score reductions of 2.99 points. 2
Critical Pitfalls to Avoid
Never delay treatment beyond 2 weeks if symptoms persist or worsen—untreated depression has significant negative consequences for maternal wellbeing, infant development, and mother-infant bonding with long-term consequences. 2, 3
Do not fail to screen for comorbid anxiety disorders, which affect up to 28.9% of postpartum women and frequently co-occur with depression. 3, 5, 6
Do not overlook the importance of involving family support systems, as partner and family support are crucial protective factors. 2
Do not assume the risks of antidepressant exposure through breastmilk outweigh benefits—the risks of untreated maternal depression generally outweigh the minimal risks of antidepressant exposure. 2
