OBG · Complications of pregnancy: fetal growth restriction

Sample item

Fetal growth restriction is best defined as an estimated fetal weight below which centile?

Original practice item, not a recalled exam question. Nothing here is recorded.

The answer and the reasoning

B. 10th centile for gestational age

FGR (or SGA) is defined as estimated fetal weight or abdominal circumference below the 10th centile (more strictly below the 3rd centile or with abnormal Doppler for the consensus definition). Symmetrical growth restriction suggests early insults such as infection or chromosomal disease, while asymmetrical growth restriction suggests uteroplacental insufficiency.

Option by option

  • A. 50th centile

    The 50th centile is the median.

  • B. 10th centile for gestational age (correct)

    Correct. Below the 10th centile is the standard definition.

  • C. 25th centile

    The 25th centile includes many normal small babies.

  • D. 90th centile

    The 90th centile defines large-for-date babies.
