A SGA is usually defined as birth weight <3rd centile.

[Feedback :- SGA is usually defined as birth weight <10th centile. Some of these babies will be normal and just genetically programmed to be small. IUGR refers to a fetus who has not grown as expected.]

B Asymmetrical IUGR usually reflects a fetal disease process.

[Feedback :- The fact that there is preservation of head (brain) growth suggests adaptation to chronic placental insufficiency or maternal disease.]

C Small mothers tend to have small babies.

This is the Correct Answer

[Feedback :- Babies reflect their mother's centile at birth and tend to graduated towards their midparental centile during the first year of life.]

D IUGR babies have more respiratory distress at birth.

[Feedback :- IUGR babies are often ‘stressed’, and the resulting cortisol secretion by their adrenal gland leads to lung maturation and less RDS.]

E The long-term prognosis for IUGR babies is better than for macrosomic babies.

[Feedback :- Macrosomic babies may have complications at or after birth (obstructed labour, hypoglycaemia) but IUGR babies carry a higher risk of long-term cardiovascular problems (hypertension, coronary heart disease) and type 2 diabetes mellitus.]
