Quantitative ultrasound (QUS) measurements in small versus appropriate birth weight for gestation neonates

Background: Small for gestation (SGA) neonates have lower birth weight (<10th percentile) and lower bone mass compared to those born with appropriate birth weights (AGA, 10th to 90th percentile). QUS measurements are thought to reflect multiple parameters in addition to bone mass which contributed to bone strength and there are limited data on QUS measurements in SGA infants.
