When to INDuce for OverWeight? (WINDOW)

Condition(s) studied

Investigational drug(s) / intervention(s)

Elective induction of labor at 39 gestational weeks and 0 to 3 days: Elective induction of labor (eIOL) according to local policies

Study summary

The rate of overweight and obese women becoming pregnant is increasing. Obesity in pregnancy along with delivery by cesarean section in obese women is associated with several complications as compared to normal weight women. The longer the woman is pregnant, the longer she is at risk. In an otherwise low-risk pregnant woman at term, it is an ongoing clinical dilemma, whether the benefits of elective induction of labor and termination of the pregnancy will outweigh the potential harms from concomitant induction and delivery process. The proposed study is a randomized controlled study of elective induction versus expectant management in obese women. The study will be carried out as a national multicenter study with inclusion of 1900 participants from Danish delivery wards. The null hypothesis is that the caesarean section rate is similar with elective induction of labor at 39 weeks of gestation, compared with expectant management among pregnant women with pre- or early pregnancy BMI≥30.
