Induced labor associated with poor school performance of offspring
According to the report by the researchers, induced labor at every WOG up to the 41st week was associated with lower school performance in the children, compared with a spontaneous birth. In addition, fewer children whose birth was induced reached a higher secondary level of education. After 38 WOG, the figure stood at 48%, compared with 54% of children who were born without intervention. For 12-year-olds not born until the 42nd WOG, there were no significant differences between the two groups investigated.
Prospective studies pending
Dr. Burger and Dr. Ravelli emphasized that the results do not indicate that every child born after an induced labor will perform worse at school. This is a statistical correlation that cannot be transferred to a case-by-case basis. In addition, it is unlikely that all disruptive factors could be taken into consideration during the analyses. Nonetheless, the researchers conclude that the long-term effects of inducing labor should be considered during consultation and decision-making in the future.
In general, it is important that future randomized, controlled studies incorporate long-term measurements in their results and conclusions so that complete data on the present topic can be gathered. “Although the effect on the individual child is likely subtle, the impact on society due to the large number of early-term labor inductions should not be underestimated,” the authors wrote.
Unexamined disruptive factors
Sven Kehl, MD, PhD, senior physician of the department of obstetrics and gynecology and coordinator of the University Perinatal Center of Franconia at the University Hospital of Erlangen, Germany, is of a similar opinion. “Inducing labor causes birth to occur sooner and therefore for the pregnancy to finish prematurely,” said Dr. Kehl. Such premature births, not the mechanical or medicinal procedures for inducing labor, could affect the child’s cerebral development. “The results of this study suggest that inducing labor in uncomplicated pregnancies, in which there are no relevant medical indications, should be avoided,” said Dr. Kehl. In these cases, the mother should wait for a natural birth.
Some of the study’s strengths include the large quantity of data, the large number of participants, and the various disruptive factors taken into consideration, such as the mother’s level of education, according to Dr. Kehl. “But it is not a study from which causality can be derived,” he said.
Not all the potential disruptive factors could be found in the available data. For example, information regarding familial status, the father’s level of education, the parents’ smoking status, or the mother’s body mass index was missing. Also, only a small number of the possible indications for inducing labor was disclosed.
No elective inductions
The study is unlikely to have a major effect on practice in German maternity clinics, since the routine induction of labor from the 39th WOG has always been regarded critically in German-speaking countries, said Dr. Kehl. It is still true that if there are any risks, a risk-benefit analysis must be performed, and the risks to the mother or child must be evaluated when considering labor induction.
“If there are no medical reasons for inducing labor, the women must also be informed about the possible long-term consequences and not just about the short-term risks,” said Dr. Kehl.
His colleague in Berlin, Michael Abou-Dakn, MD, chief physician of gynecology and obstetrics at the St. Joseph’s Hospital, Berlin-Tempelhof, was more categorical. “It is right to criticize the fact that over 20% of births in Germany are induced,” he said. He is rather dubious, however, about the effects on school performance found in the study following induced labor. Still, the investigation is a reminder that inducing labor could involve side effects. “There should therefore be no elective inductions, or any without a clear indication,” said Dr. Abou-Dakn.
