Prognostic factors of successful labor induction in women at risk of post-term pregnancy: the role of anthropometric and clinical indicators

Aim - to analyze the factors affecting the success of labor induction in patients at risk of post-term pregnancy, including anthropometric indicators, obstetric history, and clinical examinations. Materials and methods. This cohort retrospective study involved pregnant women at risk of post-term pregnancy who underwent labor induction protocols at the Kyiv Perinatal Center from January 1, 2023, to December 31, 2024. The sample included medical records of 654 patients, of whom 482 (73.7%) had successful inductions, while 172 (26.3%) required cesarean sections after failed induction attempts. Statistical analysis was performed using logistic regression. Results. It was found that age, body mass index (BMI), fetal weight, and Bishop score significantly affect the success of labor induction. Higher BMI, older maternal age, and greater fetal weight decrease the likelihood of success, while a higher Bishop score positively influences the outcome. Conclusions. Age, BMI, fetal weight, and Bishop score are key factors influencing the success of labor induction in women at risk of post-term pregnancy. The findings can be used to improve prediction models and for personalized management of such patients. The study was conducted in accordance with the principles of the Declaration of Helsinki. The research protocol was approved by the Local Ethics Committee of the institution cited in the manuscript, and written informed consent was obtained from all participants.
