Fetal growth was studied in 78 newborns who had serial scans in pregna
ncy. Weight at birth correlated with growth in the first 2 trimesters
but better with the growth between 28 and 32 weeks. The correlations f
or weight at growth cessation were better than those for weight at bir
th. Crown-heel length at cessation did not correlate with fetal growth
in the first 2 trimesters. Maternal weight increase correlated with f
etal weight and crown-heel length but not with head circumference at c
essation. Maternal prepregnancy weight correlated with fetal growth be
tween 28 and 32 weeks, but not with fetal growth in the second trimest
er. A negative correlation was found between estimated duration of gro
wth cessation and relative head circumference at birth.
