Prediction of preterm birth.

Area of Science:

• Obstetrics and Gynecology
• Maternal-Fetal Medicine
• Perinatal Research

Background:

• Preterm birth remains a leading cause of neonatal morbidity and mortality.
• Accurate prediction of preterm delivery is crucial for timely intervention.
• Cervical status assessment is a potential screening tool for preterm birth risk.

Purpose of the Study:

• To evaluate the utility of cervical status screening for predicting preterm birth.
• To compare the predictive value of cervical screening in pregnancies with and without risk factors.
• To determine the role of cervical examination in managing preterm birth risk.

Main Methods:

• Prospective study of 1327 pregnancies, categorized into high-risk (Groups I & II) and low-risk (Groups III & IV).
• Cervical scoring (Westin) performed at 24, 28, and 32 weeks gestation in Groups I, II, and III.
• Incidence of births before 37 weeks gestation recorded and predictive values calculated.

Main Results:

• Spontaneous preterm deliveries were predicted in 61% of high-risk pregnancies.
• A normal cervical score showed high predictive value (approx. 95%) across all groups.
• Pathological cervical scores had a 3-5 fold higher predictive value in risk groups compared to uncomplicated pregnancies.

Conclusions:

• Cervical screening is valuable for predicting preterm birth in pregnancies with identified risk factors.
• Cervical examination in low-risk pregnancies does not significantly improve preterm birth prediction.
• Cervical status assessment serves as a complementary tool for preterm delivery indication in women with risk factors.
