“…They concluded that there were substantially lower values for biparietal diameter and abnormal circumference in babies born preterm. The same group has also proposed that sonographic prediction of birthweight in women in preterm labour should be based on formulae specific to this particular population [20], and that diminished fetal growth in cases of preterm labour is associated with resistance to tocolysis [11]. However, the J. Perinat.…”

“…Although there is no doubt that imaging has good predictive value in respect of extremes of delivered weight [2, 6], it is far from a perfect method for accurate 'weighing' of the undelivered fetus. Nevertheless some groups have attempted to use ultrasound to compare the weight of preterm babies versus their undelivered counterparts [11,15,18,19]. Their general conclusion is that a substantial numnber of preterm babies are 'growth retarded'.…”

The objective was to determine the relationship between birthweight and anthropometric indices (PI and MAC/ OFC) in preterm infants. A group of 163 singleton preterm neonates born at 24-36 weeks were examined. Measurements were made of crown-heel length, midarm circumference, and occipito-frontal circumference. Birthweights were calculated as multiples of the mean (MoMs) for a given stage of gestation. There was a highly significant correlation between gestational age and MAC/OFC (p < 0.0001) but none with ponderal index. There was a significant correlation between weight expressed as multiples of the mean and both ponderal index (p < 0.008) and MAC/OFC (p < 0.0001). This relationship between birthweight and anthropometric indices suggests that measurement of the ponderal index does not provide a useful index of intrauterine nutrition.
