Abstract

Objective: To determine and compare either change in length, anterior angle, and consistency of cervix can be used as the predictors of preterm labor or not.

Methods: This case-control study involved 54 pregnant women with gestational age 20 - 37 weeks, which the case group is women in preterm labor and the control group were not in labor at Sanglah General Hospital, Bali, Indonesia from November 2018 to October 2019. The samples were examined using Transvaginal Sonography (TVS) to collect Cervical Length (CL), Anterior Cervical Angle (ACA), and Cervical Consistency Index (CCI) data.

Results: Short CL could increase the risk of preterm labor by 9 times (OR = 8.80, 95% CI = 2.50-30.97, p-value 0.001). Wide ACA could increase the risk by 10 times (OR = 10.45, CI 95% = 2.92-37.39, p = 0.001). Low CCI could increase the risk by 7 times (OR = 7.43, 95% CI = 1.80-30.67, p = 0.003). Anterior cervical angle has the greatest role in the occurrence of preterm labor, followed by CL and CCI, although statistically insignificant (p=0.138; p=0.212= p:0.203).

Conclusion: Performing cervical examination using TVS as the antenatal care routine can help predict and prevent preterm delivery.
