Objective This study was undertaken to evaluate the effect of different BMIs on the cervical diameter and its relation to the length of gestation among low-risk pregnant Egyptian women. Background The effect of BMI on the length of gestation is not clearly documented. There are claims that obese women may have longer gestations and longer cervices compared with normal and underweight women through changes in cervical diameters, which have an effect on the pregnancy outcome. Participants and methods This observational cohort study included 100 pregnant women from a total of 120 women at Helwan General Hospital (Egypt). All enrolled women were primigravidae with singleton pregnancies at 20-22 weeks' gestation. Enrolled women were equally allocated into four groups according to their BMIs. A vaginal ultrasonography was performed to measure the cervical length and width. Enrolled participants were followed up until delivery after recording their mean cervical length and width by transvaginal ultrasonography. Results There were five preterm births and five post-term births, representing 5 and 5% of the total cohort study. One neonatal death occurred due to prematurity, and four women developed postpartum hemorrhage with no maternal mortality. The incidence of SPTB was high among underweight women (12%) from a total of 25 women, whereas the incidence of post-term delivery was common among overweight and obese women, representing 8 versus 12%, respectively. Conclusion Underweight women are more liable to have more preterm delivery and low birth weight. However, overweight and obese women are less vulnerable to preterm delivery. They have a tendency for post-term gestation, increased incidence of cesarean section and macrosomia.
