In France, the rate of labor induction has markedly increased in recent years, partly following the ARRIVE trial suggesting short-term benefits of elective induction at 39 weeks in low-risk nulliparous women. This trial is currently being replicated in France (FRENCH-ARRIVE), as maternal characteristics, cesarean rates, and healthcare organization differ from the US. Importantly, no comparative data exist on the mid-term consequences of reducing gestational age at delivery with elective induction of labor-from 41 to 39 weeks-versus usual expectant management on child health and maternal outcomes. Generating such evidence is essential to inform decision making for women reaching 39 weeks of gestation, i.e. the large majority of pregnant women
