LONDON — Abortion does not increase a woman’s chance of developing mental health problems, according to the largest study ever to investigate the issue.
Among women with unwanted pregnancies, those who had abortions were no more likely to suffer from problems including anxiety or depression than women who gave birth, the research review by the U.K.’s National Collaborating Centre for Mental Health found.
The research shows the “reassuring news” that abortion does not cause mental health problems, but raises a warning that officials must address the problem of unwanted pregnancy, said Dr. Tim Kendall, the centre’s director.
The study is likely to be met by skepticism by those who oppose the practice and believe that terminating a pregnancy can trigger depression or other mental illnesses.
Kendall said mental health problems seemed to be linked specifically to unwanted pregnancies rather than abortion.
About 11 to 12 per cent of women in general suffer from mental health issues like anxiety or depression, but among women with unwanted pregnancies that figure rises to about one-third, he said. For women who later had an abortion, there did not appear to be any further increase in their rate of mental health problems.
“We should be looking at what it is about the unwanted pregnancy stage that is so problematic,” he said. “We need to try to get those women help sooner so they’re not put at greater risk.”
Kendall and colleagues reviewed 44 studies conducted worldwide from 1990 to 2011 that included several million women with unwanted pregnancies from sources including national health systems and insurance databases.
They concluded the best predictor of whether women would have a psychiatric problem after an abortion was whether they had mental health issues before getting pregnant. Kendall said it was possible women with mental health problems after an unwanted pregnancy were at greater risk of getting pregnant or that an unwanted pregnancy worsened their mental health.
The review was released Friday by Britain’s Academy of Medical Royal Colleges and the Royal College of Psychiatrists. It was paid for by the U.K.’s department of health.
Dr. Kate Guthrie, a spokesperson for the Royal College of Obstetricians and Gynecologists, said in a statement it was key that health care staff provide followup care to women vulnerable to mental health problems after they terminated their pregnancy. She was not connected to the review.
Guthrie said the group recently revised its own guidelines on abortion to highlight the need for health care workers to tell women about the “range of emotional responses” that might be experienced during and after an abortion.
