The clinical prediction of intrauterine growth retardation

From a total study group of 8,030 deliveries, 2,788 patients with risk factors and 292 representative patients from the 5,242 patients without risk factors were selected for detailed analysis of predictors of intrauterine growth retardation (IUGR). Two thirds of the IUGR infants came from the population with risk factors and a weighting was assigned to individual risk factors. One third of the IUGR infants came from the population without risk factors, and their mothers demonstrated significantly differing maternal characteristics from those with a normally grown infant. The perinatal mortality rate was higher in the IUGR group and particularly in the population with risk factors.
