Perinatal Outcomes and Risk Factors of Postterm Pregnancy in Women Over 35 Years Old

Postterm pregnancy remains a significant clinical problem in modern obstetrics, especially among women of advanced reproductive age. The aim of the study was to investigate the incidence of postterm pregnancy, the structure of risk factors, methods of delivery, and perinatal outcomes in women aged ≥35 years. A retrospective analysis of delivery records for 2020–2022 registered at the Osh City Perinatal Center was conducted. The types of postterm pregnancy, prevalence of extragenital pathology, obstetric history, diagnostic data, and labor management tactics were evaluated. It was established that the proportion of postterm deliveries among women over 35 years exceeds similar indicators in younger women. The most significant risk factors were anemia, chronic inflammatory diseases of the pelvic organs, and previous abortions. Features of delivery management and the frequency of operative interventions were determined. The obtained data emphasize the need for early diagnosis of postterm pregnancy and targeted preventive measures.
