What should abdominal circumference be at 36 weeks?
The study population included 3334 fetuses. Given the narrow gestational age windows, a linear model provided the best fit for median AC and SD. The equations at 20 weeks were: mean AC=-68.349+1.571*GA and SD=1.253*(-2.038+0.050*GA). The equations at 36 weeks were: mean AC=53.090+1.081*GA and SD=1.253*(0.497+0.046*GA).

What does it mean if baby has large abdominal circumference?
Fetuses with larger abdominal circumferences on antenatal ultrasounds are more likely to be macrosomic with birth weight >4000 grams (OR 2.496, p < 0.0001). Increasing fetal AC is associated with the later development of gestational diabetes (OR 2.343, p=0.0023) and polyhydramnios (OR 2.938, p=0.0003).
