Abortion does not increase women's suicide risk
Although women who have had an abortion have a higher risk for nonfatal suicide attempts, the abortion itself is not the cause, according to results of a longitudinal cohort study published in Lancet Psychiatry.
“There are 12 states that inform women seeking abortions that abortion increases or may increase their risk for suicidal ideation or mental health problems,” Julia R. Steinberg, PhD, assistant professor in the department of family science at the University of Maryland, told Healio Psychiatry. “Abortion does not cause or increase women's risk for suicide attempts.”
According to Steinberg and colleagues, certain restrictive abortion policies in the United States are based on a link between suicidal ideation and abortion, but much prior related research relied on self-report, had low participation rates and did not consider confounding factors. In the present study, the researchers obtained data from 523,280 women born in Denmark between 1980 and 1998. They used a survival analysis to examine the risk for first suicide attempt or self-harm associated with a first abortion compared with no abortion, as well as Poisson regression to examine incidence rate ratios. They also investigated whether the risk of suicide attempts changed before and after the abortion and adjusted for several factors, including age and parental mental health.
Steinberg and colleagues reported that 48,990 (9.4%) women had at least one first-trimester abortion, and 10,216 (2%) had a suicide attempt during the study period. Among the 48,990 women who had an abortion, 1,402 (2.9%) had a first suicide attempt following the first abortion. Using a model that adjusted for all covariates, the researchers found that the risk for first-time nonfatal suicide attempts was similar in the year before an abortion (incidence rate ratio [IRR] = 2.46; 95% CI, 2.22-2.72) and the year after an abortion (IRR = 2.54; 95% CI, 2.29-2.81) compared with women who had not had an abortion. The risk decreased with increasing time since the abortion, they noted.
“We should not be telling women seeking abortions that abortion may increase their risk for suicidal ideation or mental health problems, nor should mental health professionals tell or suggest to women that an abortion is the reason for any mental health problems a woman may be experiencing,” Steinberg said. “We should consider integrating mental health screenings into the abortion care setting because women having abortions are more likely to have pre-existing mental health problems.”
In a related editorial, Jenneke van Ditzhuijzen, PhD, of the University of Amsterdam, described these findings as, “a welcome addition to the academic literature.”
“Steinberg and colleagues correctly limit their analyses to first-time abortions and first-time suicide attempts; although this decreases external validity, it is a necessary step to establish causal effects and ensure temporal order,” van Ditzhuijzen wrote. – by Joe Gramigna
