The research combined data from several other studies that looked at women who delivered at full term, but whose water didn't break prior to the beginning of labor. This made sure the results only came from women whose inductions were not medically necessary.
Perhaps more surprisingly, the researchers actually found benefits of induction at 39 weeks! It was associated with slightly less blood loss as well as less meconium staining (meconium, when present, can lead to infection—or worse—for both mom and baby).
The study also found that birth weight was lower in babies of inducted mothers by about five ounces.
The study's author wasn't surprised to find some benefits to inducing at 39 weeks: "Other data point to the same effect," Vincenzo Berghella, M.D., the director of maternal fetal medicine and a professor of obstetrics and gynecology at Thomas Jefferson University, told parents.com. Unfortunately, he added, many people don't keep up with new, better data—which may be one reason why the induction-leads-to-C-section mythology endures.
8 Reasons to Wait for Your Due Date
As for what pregnant women should make of these new results? Don't ask your ob-gyn for an induction just yet. "Know that induction before 39 weeks is still not good unless there is an accepted indication," Berghella says. "At 39 weeks, it may be that indeed it's good to induce even without medical indications,
but we should wait for one more trial, currently being done by NIH."
