36 Studies Involving 1 Million Women Show Abortion Linked to Premature Birth

Preterm birth is the leading cause of perinatal mortality in the U.S. and is emotionally and financially costly for families even when it does not prove fatal to the child. That there has been significant increase in preterm birth in the U.S. in the last forty to fifty years has made researchers curious as to whether there might be a connection to abortion, legalized in 1973. Science Daily (2/3/16) says “One reason to conduct the study is that the incidence of preterm births has been rising, and falling, in parallel to popularity of abortion, the vast majority of which, until late, have been surgical.” In the last several years, researchers have published multiple studies appearing to demonstrate such a link, but now comes a meta-analysis in a major medical journal which lends strong support to that conclusion. A mega-analysis has more predictive power because it combines the results from multiple studies–in this case 36 studies covering more than one million women. The study, “Prior uterine evacuation of pregnancy as independent risk factor for preterm birth: a systematic review and meta-analysis,” was published in the May 2016 issue of the American Journal of Obstetrics & Gynecology. The authors are Vincenzo Berghella and Lisa Perriera, two researchers from Thomas Jefferson University (Philadelphia), and Gabriele Saccone, of the University of Naples Federico II in Italy. Berghella and his colleagues looked at 36 studies covering the cases of 1,047,683 women. They were looking for data that showed what happened in subsequent pregnancies after some form of “uterine evacuation”–that is, an “induced termination of pregnancy” (surgical or chemical abortion) or the use of some...
