About this study

Official title: Body Fat Index as a Novel Sonographic Tool to Predict High Risk Pregnancy (BFiORS Trial)

Primary Outcome:- GDM Diagnosis Secondary Outcomes:- Pre-eclampsia diagnosis. Cesarean section delivery due to labor dystocia defined as protracted or arrested progress of labor using labor partogram.

Read the detailed description

Obesity is one of the most common global risk factors for significant health issues, that has become increasingly prevalent among reproductive aged women. In the United States, obesity affects 21% in prepregnant females . Maternal obesity and excessive gestational weight gain have been linked to various adverse obstetric and neonatal outcomes, including spontaneous abortion, gestational diabetes mellitus (GDM), cesarean delivery, preeclampsia, neonatal macrosomia, and complications from surgery and anesthesia .

Consequently, contemporary guidelines recommend assessment of body mass index (BMI) at the first prenatal visit to guide diet and exercise directions and stratify obstetric risks . Nevertheless, BMI is associated with limitations to its clinical significance: first, it does not accurately correlate with the body fat distribution and does not differentiate between the increased mass of body muscle, bone, or fat being dependent on the patient's height and weight . Although all pregnant women with obesity is considered at risk of developing an adverse pregnancy outcome , women with BMI > 30 kg/m2 do not necessarily develop adverse outcomes, while women with BMI < 30 can still develop significant complications . Therefore, BMI does not present a clinically sensitive tool to screen and predict obesity-relevant adverse outcomes of pregnancy, including GDM, metabolic syndrome, and pre-eclampsia .

Anthropometric measurements such as waist circumference, hip circumference, waist/hip ratio, and others have been used to indicate that central fat is associated with the obesity-related adverse outcomes of pregnancy ; however, they are undermined by the subcutaneous fat amount . Computerized tomography (CT) and dual-energy X-ray absorptiometry have been implemented to measure visceral fat in the general population, which is deemed clinically related to health hazards. However, these approaches are associated with radiation exposure, associated with high costs, and are overall not appropriate for screening .

Ultrasound is safe during pregnancy and is routinely used as a part of antenatal care. Ultrasound can be used to measure visceral fat with similar sensitivity to CT in measuring fat thickness . Body fat index (BFI) is a novel tool that is calculated using the following formula (BFI = pre-peritoneal fat (mm) x subcutaneous fat (mm) / Height (cm)) . BFI was reported to be a safe, cost-effective, and easy screening method to identify the obesity-related adverse outcomes of pregnancy . Being dependent on pre-peritoneal fat which was reported to correlate with GDM with a predictive advantage over waist circumference and BMI , BFI constitutes a promising screening tool that can assess obesity-related adverse outcomes of pregnancy during first trimester scan without extra-costs and with high patient satisfaction.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • ultrasoundDiagnostic test

    Sonographic examination to measure the maternal pre-peritoneal fat thickness and subcutaneous fat thickness and calculate body fat index

Study groups in NCT05533996
Study groupRoleWhat they receive
Pregnant women prior to 14 weeksOtherThe sonographic examination will be conducted as an additional part after completing anatomical survey. . For the most accurate measurements, we will reduce the image depth to decrease the margin of error. We will conduct an initial abdominal sweep in all participants from the xiphoid to the umbilicus to detect the area of maximum pre-peritoneal fat thickness. Then, we will measure the maximum pre-peritoneal fat thickness and minimum subcutaneous fat thickness. Furthermore, all measurements will be conducted after inspiration to avoid its generated tension with the transducer just touching the skin avoiding compression of the subcutaneous fat. Two measurements will be taken to investigate the inter-observer effect. Then, BFI will be calculated using the following formula: BFI = pre-peritoneal fat (mm) x subcutaneous fat (mm) / Height (cm). Results will be communicated to the site primary investigator. The treating obstetrician will be blinded to these results.
Receives: Diagnostic Test: ultrasound

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Diagnosis of gestational diabetes (GDM)

    Diagnosis of GDM is made by abnormal glucose tolerance test during pregnancy

    Measured: Between 24 and 28 weeks of pregnancy

Secondary outcomes (2)
  1. Diagnosis of pre-eclampsia Incidence of Cesarean section

    The diagnosis is made by elevated blood pressure above 140 (systolic) and/or 90 (diastolic) in association with proteinuria

    Measured: 24 weeks of pregnancy to 10 days postpartum

  2. Labor dystocia

    Failure to progress in labour resulting in Cesarean section delivery

    Measured: At time of labour (onset of labour pain to time of delivery)
