Pregnancy May Help Reduce PTSD Symptoms
Expectant mothers are typically thrilled, but they often carry a fair amount of worry. That would seem to especially be the case for women with post-traumatic stress disorder (PTSD).
But a new University of Michigan study finds that pregnancy may actually reduce some women’s PTSD symptoms. Or at the least, it won’t cause a flare-up.
Still, the news is not great for everyone.
For about one in four women with PTSD, the opposite is true, the researchers find. Not only do their symptoms get worse as their pregnancy goes on, but their ability to bond with their newborn suffers, and they face a high risk of postpartum depression.
University of Michigan Medical School and School of Nursing researchers believe their findings highlight the need to screen pregnant women for possible undiagnosed PTSD.
The study is the first to track symptoms in women with PTSD through pregnancy and after giving birth. Findings appear in the journal Depression and Anxiety.
Investigators discovered that having PTSD in the past does not mean that problems will surface during pregnancy and in fact for many, symptoms will improve.
Specifically, more than half of the 319 women in the study had high PTSD symptoms in the first part of pregnancy, and all members of this group experienced a decrease as they got closer to giving birth. Women who had low levels of symptoms early on stayed about the same.
But for some, PTSD got worse as pregnancy went on. Those who suffered a new stress or trauma during pregnancy, or who had the most anxiety about giving birth, had the worst experience with PTSD symptoms during pregnancy, and post-birth problems.
“We hope our results give a message of hope that women who have a past diagnosis of PTSD aren’t all headed for a worsening while they’re pregnant,” says Maria Muzik, M.D., M.S., the University of Michigan psychiatrist who led the study.
“But we also have highlighted a vulnerable group that has a heightened risk of worsening symptom and postnatal issues that could have lasting effects for both mother and child.”
Muzik notes that PTSD can be caused by many things, such as combat, car crashes, being robbed or raped, living through a natural disaster or house fire, or being the victim of abuse in childhood or adulthood.
With so many possible causes, many women may not have had a formal diagnosis of PTSD before their pregnancy, but may be suffering lasting effects from their trauma.
In the study, researchers cast a wide net to find the women for their study. Funded by the National Institutes of Health, the original study was called the STACY Project for Stress, Trauma, Anxiety, and the Childbearing Year, and was lead by Julia Seng, Ph.D., a professor in the University of Michigan School of Nursing.
Nurses at prenatal clinics run by three academic health centers, including ones that served mostly women who rely on public insurance, invited thousands of women to participate in the larger STACY study.
The new data come from the subset of women who met the formal diagnostic criteria for PTSD either at the time of their pregnancy or in their past, based on detailed interviews using standard measures.
The team interviewed the women at two points during their pregnancy, and were able to interview about half the women again in the first six weeks of motherhood.
The researchers saw four groups emerge when they looked at the results of the surveys done during pregnancy: those who started high and got either moderately or substantially better, those who started low and stayed the same, and those who started relatively low but got worse.
Researchers found support network make a difference and that women with the strongest social support networks during pregnancy appeared to be protected from the risk of worsening PTSD. That means that partners, relatives, and friends can make a real difference for a pregnant woman.
Muzik hopes the new results will encourage providers who care for pregnant women to make PTSD screening part of their regular prenatal care.
“With a few questions and screening measures, they can identify women who are experiencing risk factors, and heighten their awareness for support and treatment,” she said.
“Preventing the worsening of symptoms could reduce their chance of post-birth illness, and protect their future child from the lasting ill effects that a mother’s mental illness can have.”
