Those who had had three or more induced abortions had a small, but statistically significant increased risk of having a baby with very low birth weight (less than 1500g), low birth weight (less than 2500g), or of a preterm birth (before 37 weeks), or very preterm birth (before 28 weeks), compared to women who had had no abortions. There was a slightly increased risk of a very preterm birth for women who had had two induced abortions. <\/p>\n Dr Reija Klemetti, an associate professor and senior researcher in public health at the National Institute for Health and Welfare in Helsinki, Finland, who led the research, said: \"Our results suggest that induced abortions before the first birth, particularly three or more abortions, are associated with a marginally increased risk during the first birth. However, the increased risk is very small, particularly after only one or even two abortions, and women should not be alarmed by our findings.\" <\/p>\n Most of the induced abortions (88%) were surgically performed and nearly all (91%) were performed before 12 weeks gestation. The researchers adjusted their findings to take account of various factors that could affect birth outcomes, such as social background, marital status, age, smoking, previous ectopic pregnancies and miscarriages. Multiple births (twins and triplets) were excluded. <\/p>\n The risk of having a baby born very preterm appeared to increase slightly with each induced abortion, but only the risk from two abortions or more was statistically significant. <\/p>\n \"To put these risks into perspective, for every 1000 women, three who have had no abortion will have a baby born under 28 weeks,\" said Dr Klemetti. \"This rises to four women among those who have had one abortion, six women who have had two abortions, and 11 women who have had three or more.\" <\/p>\n Among women who had had three or more abortions, there was a statistically significant increased risk of a third (35%) of having a baby born preterm (before 37 weeks), a two-fold (225%) increased risk of very low birth weight, and a two-fifths (43%) increased risk of low birth weight. <\/p>\n The study also showed a small increased risk of a baby's death around the time of birth. However, the numbers for this finding were very low (1498 births or five per 1000 babies) and so should be treated with caution. In addition, the authors say they might not have been able to fully adjust for all the factors that could affect this result and perinatal deaths are sensitive to social factors such as poverty. <\/p>\n<\/p>\n Go here to see the original: Public release date: 29-Aug-2012 [ | E-mail | Share ] Contact: Emma Mason wordmason@mac.com<\/a> European Society of Human Reproduction and Embryology One of the largest studies to look at the effect of induced abortions on a subsequent first birth has found that women who have had three or more abortions have a higher risk of some adverse birth outcomes, such as delivering a baby prematurely and with a low birth weight.
