Abstract
In Lim et al's recent article, ‘Intrauterine growth rate in pregnancies complicated by type 1, type 2 and gestational diabetes’, 1 it was interesting to note the similar growth rates and rates of macrosomia in the three types of diabetes. From a clinical point of view in diabetes we are interested in predictors of adverse outcomes such as shoulder dystocia, birth trauma and stillbirth. Although the data set may not be large enough to look at growth curves for some of these outcomes it would be interesting to examine whether the growth curves for these outcomes were different from to those for pregnancies with good outcomes. Such information may then help us identify those diabetic pregnancies that are at even higher risk and adjust care accordingly.
