keep abortion safe and legal

Abortion is often described as a necessary component of women’s health. Abortion rights groups contend that unless it is legal and freely available, backyard abortionists will fill the gap in demand and maternal mortality rates will rise. Remarkably, though, for such a contentious issue, there is little data to back up this claim.

Now a ground-breaking study of maternal mortality in Chile published this week in the leading journal PLoS One suggests that “the legal status of abortion does not appear to be related to overall rates of maternal mortality”.

Chile is an important “natural experiment” for abortion policy. In 1989 abortion was made illegal with one of the more restrictive abortions laws in the world. Good statistics from the past 50 years make it possible to compare MMRs before the ban and after.

According to Elard Koch, of the University of Chile, and colleagues,  the study “provides counterintuitive evidence showing that making abortion illegal is not necessarily equivalent to promoting unsafe abortion, especially in terms of maternal morbidity and mortality. Chile’s abortion prohibition in 1989 did not cause an increase in the [maternal mortality rate] in this country. On the contrary, after abortion prohibition, the MMR decreased from 41.3 to 12.7 per 100,000 live births –a decrease of 69.2% in fourteen years.” The highest mortality rate was in 1961 (47.9 per 100,000 women of reproductive age), and the lowest in 2003 (0.72 per 100,000).

The article is sure to prove controversial in the never-ending abortion wars in developed countries. Support for “safe, legal and rare” abortion, in US President Bill Clinton’s famous phrase, is based on two assumptions: first, that it is a fundamental right for women and, second, that it is absolutely necessary for women’s reproductive health. Koch’s analysis, the first evidence-based publication to analyse women’s health after elective abortion became illegal in a country, suggests that the second assumption may be wrong.

“The lack of correlation between high maternal mortality and prohibition of abortion observed in this study also confirms circumstantial observations made in Europe.  The lowest MMRs in Europe are in countries such as Ireland, Malta and Poland, in which elective abortion is illegal. Considering Chile has one of the lowest maternal mortality rates in the world, this analysis of Chilean maternal mortality statistics provides a model for other countries seeking a successful model for decreasing maternal mortality, and provides evidence that legalization of abortion is unnecessary to decrease maternal mortality.”

The most important factor in reducing the MMR, Koch says, is more education for women. “Educating women enhances a woman’s ability to access existing health care resources and directly leads to a reduction in her risk of dying during pregnancy and childbirth.” Other factors include: nutrition for pregnant women and their children in the primary care network and schools; universal access to improved maternal health facilities; changes in women’s reproductive behavior enabling them to control their own fertility; and clean water and good sanitation.
