Abstract

Background: Pregnant women with a short cervix are at risk for spontaneous preterm birth. Cervical length measurement is a screening tool to identify women at risk; however, second trimester cervical length measurement in every woman is burdensome.

Objective: To assess possible associations between clinical characteristics/obstetric history and cervical length in the hope of establishing a screening tool for short cervix.

Methods: A cross-sectional study on singleton pregnancies was conducted at Somdejprasangkharach 17 Hospital, in which cervical length was measured during 16-24 weeks of gestational age. Data on obstetric history, clinical characteristics, and cervical length were collected from April 2021 to January 2022. Univariate and multivariate linear regression analyses were performed to assess the relationship.

Results: There were 300 eligible pregnant women. The mean cervical length was 40.77 mm. Using univariate analysis, no association was found between cervical length and maternal height, BMI, and weight, but the cervical length was significantly associated with age, current bodyweight, and obstetric history (p-value = 0.033, 0.035, 0.045, respectively). However, the results from multivariate linear regression analysis demonstrated that age, current body weight, and obstetric history had no significant association with cervical length (p-value = 0.221, 0.094, 0.218, respectively).

Conclusion: Age, weight, height, BMI, and obstetric history were not significantly associated with second-trimester cervical length.
