Induced Labor After 39 Weeks Can Reduce the Need for Cesarean Birth
Inducing labor at 39 weeks of pregnancy in first-time mothers can reduce the chances of cesarean birth.

Approximately one-third of women in the United States give birth via cesarean delivery. While life-saving in the right circumstances, cesarean birth also carries with it significant risks, including an increased likelihood of infection, hysterectomy, placenta implantation abnormalities in future pregnancies, and respiratory illness in infants.


In a study with more than 6,100 pregnant women across the country, researchers randomly assigned half of the women to an expectant management group (waiting for labor to begin on its own and intervening only if problems occur) and the other half to a group that would undergo an elective induction (inducing labor without a medical reason) at 39 weeks of gestation.


Results include:

  • Lower rates of cesarean birth among the elective induction group (19%) as compared to the expectant management group (22%).
  • Lower rates of pre-eclampsia and gestational hypertension in the elective induction group (9%) as compared to the expectant management group (14%).
  • Lower rates of respiratory support among newborns in the induction group (3%) as compared to the expectant management group (4%).
"Safe reduction of the primary cesarean is an important strategy in improving birth outcomes," said William Grobman, Professor in obstetrics and gynecology at Northwestern University's Feinberg School of Medicine.

SMFM'scurrent guidelinesdo not recommend routine induction of labor for low-risk pregnant women at 39 weeks of gestation. "SMFM will wait to evaluate the peer-reviewed publication of the ARRIVE Trial before providing any guidance or changes to our existing recommendations," said Alfred Abuhamad, MD, the President of SMFM.
