Perinatal Depression and Anxiety
Depression and anxiety are two of the most common complications women experience during pregnancy and the postpartum period. Much of the research in the past has focused on postpartum depression. More recent research has shown that women experience depression and anxiety disorders, as well as other mental health conditions, during pregnancy and postpartum. These conditions, sometimes termed perinatal mood and anxiety disorders, are associated with significant effects on the health of the mother and her child if not treated.
The American Psychiatric Association Diagnostic and Statistical Manual of Mental Disorders (DSM)-V does not recognize perinatal depression as a separate diagnosis. Rather, patients must meet the criteria for a major depressive episode and the criteria for the peripartum-onset specifier. The definition is therefore a major depressive episode with an onset in pregnancy or within 4 weeks of delivery.1 However, research indicates women are at risk for depression and anxiety up to 12 months postpartum.
Perinatal depression and anxiety are generally treatable conditions. Effective screening, diagnosis, and treatment of symptoms can substantially improve health outcomes for children, mothers, and families.
Signs and Symptoms
Many women experience transient and mild mood disturbances during the perinatal period. However, some women experience a more disabling and persistent form of depression or anxiety that requires treatment.2
Signs and symptoms of perinatal depression and anxiety include:
- Persistent sadness
- Impaired concentration or indecisiveness
- Disconnection from emotions
- Anxiety around the newborn
- Feelings of inadequacy or guilt
- Irritability or mood changes
- Lack of interest in the newborn, family, or activities
- Recurrent thoughts of death or suicidal ideation*
- Racing thoughts
The prevalence of perinatal depression varies with the population surveyed. However, there is agreement that depression is one of the most common complications women experience during the perinatal period. According to recent research:
- As many as 13% of women in the U.S. reported frequent symptoms of depression after childbirth.3 The most prevalent concurrent disorders in depressed pregnant and postpartum women were anxiety disorders (43%).4
- Among non-depressed pregnant or postpartum women, 11% screened positive for anxiety disorders.5
- Among teen mothers, the prevalence of postpartum depression ranged from 53% to 61%.6
- Among active duty servicewomen, close to 10% who gave birth for the first time were diagnosed with postpartum depression, while 8.2% of dependent spouses of military personnel were diagnosed.7
Researchers suspect many women go undiagnosed and that the actual number of women who experience depression and anxiety during the perinatal period may be much higher.
Etiology and Risk Factors
The etiology of perinatal anxiety and depression is not readily known. Researchers think depression and anxiety during this time is likely caused by a combination of physical, emotional, and environmental factors.
However, several factors are associated with increased risk of perinatal depression and anxiety, including:
- A history of depression, anxiety, or other mental health problems8
- Family history of depression, anxiety, or other mental health disorders9
- Traumatic pregnancy or birth experience10
- Multiple births, including twins or higher order multiples11
- Poor partnership relationship quality12
- Lower socioeconomic status13
- Low levels of social support14
- Unintended pregnancy15
- Teen pregnancy16
- Military service17
- Domestic violence18
Adverse Effects to Mother and Infant
Prenatal Health Consequences
Research continues to explore the effects of women’s prenatal psychological distress on fetal behavior and child development, and the biological pathways for this influence. Studies have shown depression during pregnancy is associated with harmful prenatal health consequences, which may compromise the health of both the mother and her fetus:
- Poor nutrition
- Poor prenatal medical care
- Risk of suicide
- Harmful health behaviors (e.g., smoking and alcohol or other substance misuse)19
Women with depression during pregnancy are at increased risk for preterm birth and infant low birth weight.20
Postpartum Health Consequences
Disruption of early maternal-infant bonding has been shown to impact an infant’s early development. Depressed women have been found to have poorer responsiveness to infant cues and more negative, hostile or disengaged parenting behaviors.21 These disruptions in maternal-infant interactions have been associated with adverse effects on the infant:
- Cognitive and language development delays.22,23,24
- Social engagement, stress level, and fear reactivity.25
In early 2016, the U.S. Preventive Services Task Force (USPSTF) released recommendations for the screening for depression in the general adult population, including pregnant and postpartum women.26
Although screening is important for detecting perinatal depression and anxiety, screening by itself is insufficient to improve clinical outcomes and must be coupled with appropriate follow-up and treatment when indicated.
Obstetricians and Gynecologists
The American College of Obstetricians and Gynecologists (ACOG) 2015 Committee Opinion recommends women be screened at least once during the perinatal period for depression and anxiety.27 The College recommends that clinical staff in obstetrics and gynecology practices be prepared to initiate medical therapy, refer patients to appropriate behavioral health resources when indicated, or both.
The American Academy of Pediatrics, based on a 2010 clinical report, encourages pediatric practices to screen mothers for postpartum depression, use community resources for the treatment and referral of the depressed mother, and provide support to the mother-child relationship.28
The Association of Women’s Health, Obstetric and Neonatal Nurses recommends that all women be screened for mood and anxiety disorders. Nurses are in key positions to screen women, provide education regarding perinatal mood and anxiety disorders to pregnant and postpartum women, and their families, and to ensure appropriate referrals.29
In addition, the American Psychological Association supports universal screening for depression in the perinatal period, noting that maternal depression often goes unrecognized and untreated because pregnant and postpartum women are not universally screened for depression.30,31
The recommendations correlate with recent studies finding that screening can significantly reduce postpartum depressive symptoms when there is adequate follow up.32
Several screening instruments have been validated for use during pregnancy and the postpartum period. The USPSTF recommends clinicians choose the method most consistent with the patient being served, the practice setting, and their personal preference.33
A screening tool measures the level of risk and should not be used to diagnose a patient. Referral to the patient’s primary care provider or to a mental health professional can ensure women get the diagnosis and treatment they need.

In most cases, depression and anxiety will not subside on their own and require treatment. The two most common forms of treatment for perinatal depression are medication and/or psychotherapy. Lifestyle behaviors can work in tandem with treatment and help patients to manage symptoms.
The choice of treatment depends on the severity of symptoms, the woman’s needs and preferences, and the availability of services.
Appropriate pharmacologic treatment is available for most pregnant and breastfeeding women.34 The benefits and risks, as well as alternatives to medications, should be carefully explained to the patient. The research on the use of psychiatric medications during pregnancy is limited. The risks are different depending on which medication is taken, and at what point during the pregnancy the medication is taken.35 Antidepressants, especially selective serotonin reuptake inhibitors (SSRIs), are considered to be safe during pregnancy. However, antidepressant medications do cross the placental barrier and may reach the fetus. Birth defects or other problems are possible, but they are very rare. The effects of antidepressants on childhood development remain under study.36
Similarly, pharmacological treatment while a woman is breastfeeding can put the infant at risk for adverse effects. The U.S. National Library of Medicine LactMed® database lists possible effects of drugs and other chemicals to a breastfed baby.
Psychotherapy, such as cognitive behavioral therapy, is a suitable treatment option for some women, particularly those concerned about taking medications while pregnant or nursing. For others, psychotherapy may be used in conjunction with pharmacological treatments. Psychotherapy should be provided by a qualified mental health professional.
Lifestyle and Behaviors
Perinatal depression and anxiety generally require treatment. In addition to treatment, there is some evidence that lifestyle changes may help to build on the treatment plan and help speed recovery. Therefore, it may be helpful to recommend lifestyle or behavior changes to your patients who are dealing with depression or anxiety. These may include finding ways to be physically active, getting more rest, optimizing nutrition and overall health, and finding help with childcare.
