A new study in France shows that an induced abortion can increase the risk by premature birth in subsequent pregnancies by as much as 70 percent. That's because the abortions can damage the lining of the uterus, where unborn children grow and developed.
The study was based on medical notes and interviews of 2837 French women who had a premature birth during 1997, which represents about one-third of the total number of premature births that year. Those who gave birth between 28 and 32 weeks of pregnancy were 40 percent more likely to have had an abortion compared with mothers who gave birth within two weeks of the expected due date. Mothers who gave birth to babies from 22 to 27 weeks into the pregnancy were 70 percent more likely to have had an abortion.
