In previous studies of the intersection of reproductive health and mental health, Munk-Olsen's team has failed to control for the impact of prior pregnancy losses (miscarriage and induced abortion). See for example Munk-Olsen T, 2012, Munk-Olsen T, 2012, Munk-Olsen T, 2011 and my comments on each entry with requests for additional analyses to address these oversights . . . all of which have been refused.

In this case, once again, Munk-Olsen's examination of psychiatric disorders following fetal death is flawed by her decision to disclose the effects of induced abortions on the analyses. She reports that IRR were adjusted for "age, calendar period, parity status, induced abortion status and family history of formerly treated psychiatric disorders" but she chose not to report on how each of these factors contributed to psychiatric illness. This appears to be selective reporting to avoid publication of data that contradicts her previous claims that abortion does not contribute to mental health problems.

Numerous other researchers, in many countries using many different methodologies, have found that both natural miscarriage and induced abortion have distinct effects on subsequent mental health, especially during and after subsequent pregnancies. Below is a list of such studies.

I once again ask Munk-Olsen to address these oversights by publishing analyses which compare outcomes relative to the full reproductive history of women, including segregated results showing the outcome relative to no prior pregnancy loss, one or more miscarriages, one or more induced abortions, and for women with a history of at least one induced abortion and one miscarriage.
