title: Screening for hyperglycaemia in pregnancy: analysis of two screening protocols and review of current methods.
abstract: We assessed the ability of two screening protocols to detect varying degrees of hyperglycaemia in pregnancy and to compare fetal outcome in those found to have normal and abnormal glucose metabolism by either protocol. 493 pregnant women were identified by one of two screening protocols to be at risk of hyperglycaemia in pregnancy. Pregnancy complications, induction of labour, method of delivery, birth weight, incidence of congenital anomalies and neonatal complications were assessed; there were no significant differences between those with normal and abnormal glucose metabolism detected by either protocol apart from a significant linear trend for the incidence of large for gestational infants with increasing hyperglycaemia in both groups. Protocol B was as effective in detecting new hyperglycaemia in pregnancy as Protocol A. It involved the use of a breakfast meal profile in the initial assessment of those screened positive, reducing the need for glucose tolerance tests in the vast majority of cases. In the population studied, hyperglycaemia in pregnancy was not associated with adverse fetal outcome.
