02F13963A meta-analysis combining the results of 8 studies of women facing unwanted pregnancies, published in the April 2013 issue of the Australian and New Zealand Journal of Psychiatry, has concluded that:

“there is no available evidence to suggest that abortion has therapeutic effects in reducing the mental health risks of unwanted or unintended pregnancy.”

To the contrary, the combined results indicated that, compared to delivery of an unwanted or unintended pregnancy, abortion “was associated with small to moderate increases in risks of anxiety, alcohol misuse, illicit drug use/misuse and suicidal behavior.”

According to the authors, the absence of any “beneficial consequences for the mental health of women having unwanted or unintended pregnancy” poses a particularly pressing legal dilemma in England, Wales, Scotland, New Zealand, and most states in Australia.

Abortion is only legal in these countries if there is reasonable medical evidence that abortion reduces the physical or psychological health risks associated with continuing the pregnancy.

Over 90 percent of abortions in these societies are provided on the grounds that abortion has mental health benefits compared to carrying an unwanted pregnancy to term.  But as noted by the authors, there is literally no medical evidence to support the conclusion that abortion ever reduces mental health risks.

This means that abortions “officially” being performed for reasons of psychological health are actually being performed in violation of the principles of evidence based medicine, since there is no evidence of any mental health benefits associated with abortion.

While not discussed by authors, the same problem surrounds cases where abortion is recommended in order to reduce the physical risks associated with pregnancy.  There are literally no studies showing that abortion reduces physical risks to women.  Instead, every record linkage study examining mortality rates associated with abortion show that abortion is also linked with an elevated risk of maternal death in both the short term and the longer term.  This mortality research creates a strong presumption against accepting that abortion has a beneficial impact on physical health compared to allowing pregnancies to continue.
