Ethnic differences in fetal size and growth in non-GDM pregnancies.

<p>Mean difference in z-score for estimated fetal weight (black circles), head circumference (HC, black squares), abdominal circumference (AC, white circles) and femur length/length (white squares), in South Asian non-GDM, compared with European non-GDM pregnancies, at four time points (gestational week 24, 32 and 37 during pregnancy and at birth). Estimates are gestational age specific z-scores extracted from a linear mixed model, adjusted for maternal parity and fetal gender. Ethnic Europeans are reference group, represented by the zero-line.
