The strongest risk factors for initiating antidepressant use were indicators for earlier mental health problems, such as a previous psychiatric contact. The authors speculated that mental health problems may lead women to have unintended pregnancies and therefore abortions, as Kelli Stidham Hall, PhD, and associates discussed (Soc Sci Med. 2014 Jan;0:62-71).
The combination of the absence of a postprocedure increase in antidepressant use, the gradual decrease in their use over time, and the lack of statistical significance of the incidence rate ratios when adjusted for risk factors led Dr. Steinberg and her coauthors to conclude that “compared with women who do not have an abortion, women who have an abortion may be at higher risk of depression after undergoing the procedure because they were at higher risk to begin with.”
Dr. Steinberg disclosed that she has served as a scientific expert on the topic of abortion and mental health in legal cases and has consulted for the Center for Reproductive Rights and Planned Parenthood Federation of America. The study was supported by grants from the Society of Family Planning, the American Foundation for Suicide Prevention, and the Lundbeck Foundation Initiative for Integrative Psychiatric Research.
