Fetal adiposity composite is calculated by adding fetal thigh adiposity with fetal abdominal adiposity.

Fetal thigh adiposity is calculated as the difference between the outer edge of the femur to the outer surface of the fetal skin minus outer surface of the femur to the inner fat surface.

The measurements are taken at the mid shaft of the femur.

Fetal Abdominal adiposity is calculated at the level of fetal AC, subcutaneous tissur at the half way between the edge of the rib and anterior abdominal wall , including skin.

The adiposity composite of 90th centile at 36 weeks is 8.1.

This is used, when EFW is exceeding more than 95th centile/ 4000 to 4500 grams fetal wt, polyhydramnios, high maternal BMI.

Used in suspected as well as diagnosed cases of GDM.

In cases that are not diagnosed of GDM, if we encounter or suspect fetal macrosomia, this can help us give additional or adds to our diagnosis. Thus helping managing such pregnancies, to avoid stillbirths.
