A new study shows that women with clinically diagnosed perinatal depression face an increased risk of death as a result of suicide, especially during the first year after receiving a diagnosis. The results were published January 10 in the
Researchers examined data from the Swedish national registry between 2001 and 2018 and found 86,551 women with a first-time diagnosis of perinatal depression and 865,510 women without perinatal depression who gave birth around the same age and during the same year.
They also looked at data for 24,473 of the women who had perinatal depression with 246,113 full sisters who were unaffected by this illness and gave birth to at least one baby throughout the study duration.
The findings demonstrate that women with perinatal depression are more than twice as likely to die compared to women who do not have perinatal depression. The risk appears highest during the first year after being diagnosed.
While suicide is rare for people with perinatal depression, the increase in suicide was nearly six fold compared to people without this mental illness. Those with perinatal depression were also three times as likely to die from an accident, the researchers report.
“This study uses a large dataset from Swedish registries and demonstrates a significant association between peripartum depression and risk of suicidal behavior,” Dr. Khatiya Moon, a psychiatrist at Northwell Health, told Healthline. Moon was not involved in the research.
“A strength of the study is that the investigators tried to control for factors like upbringing and previous history of depression or other psychiatric disorders, which could otherwise confound the results,” she added.
In the study, researchers discovered that women with perinatal depression had a greater risk of mortality.
The findings were consistent regardless of any pre-existing psychiatric conditions, particularly among people who died by suicide and during the first year after being diagnosed.
“Becoming a parent is a major life transition,” Moon said. “Not only are there massive hormonal shifts that affect the brain and body of the postpartum person, the psychological transition to parenthood is among the most dramatic changes most people ever go through.”
“The parenthood transition also changes how a person relates to others and what supports they may need. Without the right support, the postpartum period can be fraught with challenges. This study is another reason to take perinatal depression seriously as a contributor to maternal mortality,” Moon added.
The study also highlights the risks associated with major depression, a recurrent mental illness.
“Major depression is a serious illness associated with high risk for other medical illness and mortality, including suicide,” Dr. Adele Viguera, associate director of the Perinatal and Reproductive Psychiatry Program at Cleveland Clinic, told Healthline. Viguera was not involved in the new research.
“These findings underscore the serious morbidity and elevated mortality associated with major depression, whether postpartum or not. If a person has had one episode of major depression, their risk for developing a subsequent episode is
“If an individual has experienced at least two episodes, their risk for having another episode increases to 80%. Postpartum depression is no different with respect to these serious consequences, including elevated risk for subsequent recurrences both postpartum and outside of the postpartum period,” Viguera continued.
Michele Goldman, a psychologist with the Hope for Depression Research Foundation, told Healthline while the study highlights the importance of monitoring and intervening in higher-risk populations, “there was a lack of clarity in the study that brings up additional questions about the findings.”
“The study defines depression as people having received a diagnosis by a professional after receiving specialized care or because someone was dispensed an antidepressant medication,” Goldman explained.
“Being on an antidepressant medication does not constitute a diagnosis of depression; further, there are people on antidepressant medications to treat other conditions (not depression). Therefore, their main criteria to categorize women as having depression is not necessarily a sound measure,” Goldman noted.
Many factors contribute to perinatal depression, the period before and after the birth of a child.
Moon said the exact causes of perinatal depression are not fully understood but noted the causes may vary from person to person.

“This was part of the rationale in the development of zuranolone and brexanolone, which are both FDA approved for [the] treatment of postpartum depression and both involved in GABA modulation,” he added.
The postpartum period also brings a rapid shift in hormones such as estrogen, progesterone, and allopregnanolone. Postpartum depression affects around
“As these hormones influence mood-regulating neurotransmitters, it is thought they may play a role in postpartum depression,” Viguera said.
“However, studies find no consistent link between hormone levels and mood issues after birth. Still, some think certain women are
Beyond hormones, other factors also seem to be at play.
“Consistently, women who report marital dissatisfaction, insufficient social support, and stressful events during or after pregnancy have higher rates of postpartum depression,” Viguera said.
“The condition likely indicates an underlying susceptibility to depressive disorders. Women with histories of depression or bipolar disorder are at greater risk, and women who develop postpartum depression often have recurring depressive episodes unrelated to reproduction.”
While hormones may contribute to perinatal and postpartum depression onset, psychological and social factors also affect risk a person’s risk.
All new birthing parents are at risk for developing postpartum depression regardless of age, relationship status, education, or income level. However, certain risk factors may increase a person’s likelihood of developing this debilitating mental health condition. According to Viguera, these include:
- previous postpartum depression
- depression during pregnancy
- personal or family history of depression
- recent major stressors
- inadequate social support system
- marital conflict
Perinatal and postpartum depression is treatable, especially when diagnosed early.
“It is imperative to evaluate and diagnose postpartum mood disturbances,” Viguera said.
“Often, a first step is screening, followed by referral to an expert in this area. The approach to treatment is multi-prolonged and can include a variety of treatment modalities, usually in combination such as with talk therapy, medications, involving family members to provide support at home and community support services.”
Antidepressants such as selective serotonin reuptake inhibitors (SSRIs) and serotonin-norepinephrine reuptake inhibitors (SNRIs) are commonly prescribed for treating perinatal and postpartum depression.
“These can help manage symptoms and regulate mood,” said Viguera.
“An exciting development in the treatment of postpartum depression is the recent release of the first-ever
Various psychotherapies can also be very helpful in treating postpartum depression.
“For example, cognitive behavioral therapy helps identify and change negative thought patterns, or interpersonal therapy focuses on improving communication and relationships,” Viguera said, noting that group therapy connects pregnant and postpartum people around similar difficulties.
In many cases, the combination of talk therapy and medication provides a better outcome for recovery than either modality alone. Other helpful interventions for perinatal depression may include:
- getting adequate sleep
- following a balanced diet
- exercising regularly
- joining support groups
“Having a strong support system is also crucial,” Viguera said. “Partners, family, and friends can provide emotional support and practical help with child care to alleviate stress. In general, treatment is tailored to each woman’s needs and symptoms with the goal of restoring mood and daily functioning.”
Moon added that pre- and post-natal care appointments “go a long way” for most people.
“Pregnancy and parenthood also provide the opportunity to connect with people in one’s community in a new way, and it can be helpful to build networks of other parents through childbirth and parenting classes, support groups, and mother-infant classes,” Moon said.
If you’re experiencing symptoms of peripartum anxiety and depression, it’s important to seek treatment and bring up concerns to your healthcare team, such as an OB-GYN.
A new Swedish study shows an increased risk of death, particularly death by suicide, among people diagnosed with perinatal depression.
The findings highlight the mortality risks associated with perinatal, postpartum, and major depression, which are debilitating mental health disorders when untreated.
“It is well known that people with mental disorders experience excess mortality compared with the general population,” Viguera said. “Postpartum depression is no different with respect to these serious consequences.”
