March 3, 2011 -- Feelings of depression and anxiety following a miscarriage may last for almost three years after the birth of a healthy baby, finds a new study in the British Journal of Psychiatry.
“Health providers and women themselves think that once they have a healthy baby after a loss, all would be fine and that any anxiety, fears, or depression would go away, but that is simply not the case,” says study researcher Emma Robertson Blackmore, PhD, an assistant professor of psychiatry at the University of Rochester Medical Center. “I honestly thought that once a woman had a baby or had gone past the stage of her previous loss, the anxiety and depression would go way, but these feelings persist.”
Of 13,133 pregnant women studied, 21% had experienced one or more previous miscarriages, 108 had one previous stillbirth, and three women had two previous stillbirths. All of the women in the study were assessed for depression and anxiety during their pregnancy and after having their babies.
Among the women who had one previous miscarriage or stillbirth, 13% were still experiencing symptoms of depression almost three years later, and about 19% of women who had two previous pregnancy losses were still depressed after 33 months, the study showed.
The traits that may protect some women from developing lingering depression or anxiety following a miscarriage or stillbirth are not known, Blackmore says. “It could be biological or that they are more resilient or maybe they have more peer support.”
History of pregnancy loss may be a risk factor for postpartum depression in a similar way as other known risk factors, such as personal or family history of depression, the researchers write.
Depression or anxiety can have negative consequences for moms and their newborns. “Identifying women at risk can help get them the help that they need,” Blackmore says.
“Don't assume having a healthy baby will resolve your previous anxiety and depression, and be on the lookout for signs,” she says.
Signs that a women may still be recovering emotionally from pregnancy loss include feelings of sadness that affect everyday functioning, not sleeping, obsessing about the current pregnancy, and going to the doctor repeatedly for test after test, Blackmore says.
