THE THORP LITERATURE REVIEW, 2002
Reference: Thorp, et. al., Long term Physical and Psychological Health Consequences of Induced Abortion: Review of the Evidence; (OB GYN Survey, Vol 58 #l, 2002).
6 studies, totaling 10,790 patients, show no association between spontaneous abortion (“miscarriage”) and subsequent preterm birth.
12 studies, totaling 34,929 patients, showed no association between induced abortion and preterm birth in a subsequent pregnancy. 12 studies, totaling 219,851 showed an association between induced abortion and subsequent preterm birth, with a risk up to double the expected risk.
Thorp identified a “dose response” effect, i.e., the more IA’s, the higher the risk of subsequent preterm birth.“
