To elucidate whether induction of labor in primiparas with low-risk pregnancies at 38 + 0 to 40 + 6 gestational weeks will increase the cesarean rate, compared with those receiving labor induction at more than 41+0 gestational weeks.

Medical records of all consecutive primiparas with low-risk pregnancy from January 1, 2014 to August 31, 2019 were reviewed to explore the correlation between early induction of labor and caesarean birth after 38 + 0 weeks. The hypothesis of the study is that induction of labor in primiparas with low-risk pregnancies at 38 + 0 to 40 + 6 gestational weeks will increase the cesarean rate, compared with those receiving labor induction at more than 41+0 gestational weeks.

Inclusion Criteria:

• After 38 + 0 weeks of gestation
• low-risk pregnant primiparas
• singleton
• nulliparous
• > 20 years old

Exclusion Criteria:

• Premature rupture of membranes
