Abstract

Background and Objective: The preterm delivery was dependents on various factors, includes with cervical changes. The study of 2016 and 2018 in Europe and Americas found the cervical length (CL), uterine cervical angle (UCA) and gestational age were predictive factors for preterm delivery. Risk for preterm delivery may varies for difference races. Primary objective was prediction of spontaneous preterm birth with UCA in Northeastern Thailand population.


Methods: A cross sectional study in single pregnancy, age > 18 years with ultrasonographic examination at antenatal care unit, Srinagarind Hospital.


Results: The mean of gestational age, CL, UCA and gestational age at delivery were 20.20±1.30 yr., 3.74±0.67 cm, 93.93±18.75 degree and 38.37±1.84 weeks, respectively. The preterm delivery was associated with UCA< 97 degree. Sensitivity, specificity, positive predictive value and negative predictive value were 57.9%, 54.9%, 14.7% and 90.7%, respectively.


Conclusion: The preterm delivery was associated with UCA<97 degree. Sensitivity, specificity, positive predictive value and negative predictive value were 57.9%, 54.9%, 14.7% and 90.7%, respectively.
