Assess the relationship between maternal body mass index and second trimester cervical length
This is a prospective study conducted on 100 singleton women, aged between 18 to 34 years with mean age of 24.03 ± 4.34 from 2017 to 2019, all these women have their BMI measured in 1sttrimester according to WHO criteria and cervical length measured in 2nd trimester (16–24 weeks)
The rate of premature delivery among women aged ≥ 25 years was 52.3% compared to 35.7% among those aged <35 years (p = 0.097). The rate of premature delivery among women living in rural areas was 52.9%, compared with 41% among women living in urban areas (p = 0.363). The more the body mass index (BMI), the less the rate of premature delivery (p = 0.002) where it was 50% among thin women and 0% among obese women. Premature delivery was 89.5% among women with short cervical length and 32.1% among women with normal cervical length (p < 0.001). 19% of the women of the whole sample had short cervix but none of the women with normal weight or obese had short cervix.
This study demonstrates a relationship between BMI and cervical length suggesting that obesity may be associated with longer cervical length.
