Vaginal delivery significantly increases the risk of pelvic organ prolapse (POP). Each additional vaginal birth further elevates this risk, while cesarean delivery shows no impact on POP development.
Area of Science:
- Obstetrics and Gynecology
- Pelvic Health Research
- Women's Health Studies
Background:
- Pelvic organ prolapse (POP) affects a significant number of women.
- Understanding risk factors like mode of delivery and parity is crucial for prevention and management.
Purpose of the Study:
- To investigate the association between mode of delivery, parity, and the occurrence of pelvic organ prolapse.
- To quantify the risk of POP based on the number of vaginal deliveries.
Main Methods:
- Cross-sectional study involving 1964 women with benign gynecological disorders.
- Utilized the Pelvic Organ Prolapse Quantification (POP-Q) system for assessment.
- Collected data on obstetrics history, including mode of delivery and parity.
Main Results:
- Vaginal delivery was independently associated with a higher risk of POP (OR 2.92).
- Each subsequent vaginal delivery increased POP risk (OR 1.23).
- Cesarean delivery did not demonstrate a significant association with POP development.
Conclusions:
- Vaginal delivery is an independent risk factor for pelvic organ prolapse.
- Increased parity through vaginal births correlates with a higher risk of POP.
- Cesarean delivery appears to have a protective or neutral effect regarding POP development.
