Decreased bone ultrasound velocity in large-for-gestational-age infants.
BACKGROUND
Bone speed of sound is a measure of bone breakability. There are few reports on bone mineral content in large for gestational age infants; most of them in infants of diabetic mothers. There are no data on bone speed of sound in large for gestational age infants of nondiabetic mothers.


OBJECTIVE
To test the hypothesis that large for gestational age infants of nondiabetic mothers have lower bone speed of sound than appropriate for gestational age infants.


METHODS
Bone speed of sound was measured within the first 96 hours of life at the right tibial midshaft in 25 singleton large for gestational age infants of non diabetic mothers and compared to appropriate for gestational age controls.


RESULTS
Bone speed of sound measured in large for gestational age infants of nondiabetic mothers was lower than in controls.


CONCLUSIONS
Large for gestational age infants of nondiabetic mothers have lower bone speed of sound than controls.
