Antenatal depression

Did You Know?

• More than 10% of fathers experience paternal perinatal depression (PPND).
• Studies have determined there may be a connection between antenatal and postpartum depression in women with lower vitamin D levels.
• Men whose partners are women struggling with antenatal or postnatal depression often find themselves receiving less affection and intimacy from their partners.

Signs and symptoms

Antenatal depression is diagnosed when common pregnancy-related shifts in mood, memory, appetite, and sleep become severe enough to disrupt daily life. Symptoms include trouble concentrating, intense anxiety or fear, memory lapses, emotional numbness, extreme irritability, sleeping too much or too little or fitfully, unrelenting exhaustion, overeating or undereating, weight changes not due to pregnancy, loss of sexual desire, a pervasive sense of dread about the pregnancy and everything else, feelings of guilt or failure, ongoing sadness, and suicidal thoughts. Additional signs may involve an inability to feel excited about the pregnancy or baby, a sense of disconnection from the baby, and difficulty bonding with the developing child. These symptoms can seriously harm the mother-baby relationship and impair the mother’s ability to care for herself, raising further risks. Triggers include relationship troubles, a personal or family history of depression, infertility, previous pregnancy loss, pregnancy complications, and past abuse or trauma. Other contributing factors are unintended pregnancy, hyperemesis gravidarum, financial strain, housing issues, and dynamics with the baby’s father or family. For years, it was wrongly assumed that pregnancy hormones protected against depression, leaving women vulnerable only after birth when hormone levels dropped. This misconception explains why antenatal depression was only recently recognized.

Screening

Catching depression early during pregnancy and after childbirth is crucial, which is why many experts push for routine mental health checks. The American College of Obstetricians and Gynecologists, along with other maternal health groups, strongly advises that all pregnant and new mothers be screened for depression as part of standard care. Several states, like California, have even passed laws requiring doctors to do these screenings at visits, since early detection can speed up access to effective help. Two common screening tools are the Patient Health Questionnaire 9 (PHQ-9), which matches the nine symptoms of depression from the DSM-IV, and the Edinburgh Postnatal Depression Scale, originally made for after birth but now also proven reliable during pregnancy. Simply screening isn't enough, though. Healthcare systems must also put in place steps like referrals to treatment and ongoing monitoring to support women throughout their recovery. Additionally, research shows that women with obesity are more likely to experience mental health struggles, so they should bring up any symptoms with their doctor at their first prenatal appointment.

Treatment

Treatment for antenatal depression poses challenges because the baby is also affected by any treatment given to the mother. Psychotherapy is recommended for any woman with antenatal depression, as it is an effective way for the mother to express her feelings. Cognitive behavioral therapy effectively helps decrease symptoms. Being seen by a psychiatrist is recommended for assessment of medication benefits and specific recommendations. Familial support may help with emotional aspects. Nonspecialist providers such as lay counselors, nurses, midwives, and teachers with no formal training in counseling interventions often fill a gap in providing effective services related to depression and anxiety treatments. Forms of exercise such as yoga, walking, stretching, and aerobic exercise can help with depressive symptoms both before and after birth, but not prevent it entirely.

Antenatal depression and infant health

Antenatal depression may raise the chance of miscarriage. Experts disagree on whether miscarriage stems from the depression itself or from antidepressant use. A large Danish study found that depressed women not taking SSRIs had more first-trimester miscarriages than non-depressed women who did take SSRIs, suggesting the mother’s mental state, not the medication, could be the cause. Depression during pregnancy also harms infant health. Babies born to depressed mothers face higher hospitalization rates, lower birth weight, earlier delivery, poorer growth, more diarrheal infections, and less breastfeeding. Positive depression screenings in the first or third trimester are strong predictors of early breastfeeding cessation. The effects of maternal depression can reach into the child’s adulthood. Women from low socioeconomic backgrounds experience worse outcomes, including more preterm births and low birth weight.
