Objective To evaluate early fetal growth and the biomarkers, pregnancy-associated plasma protein A (PAPP-A) and free beta-human chorionic gonadotrophin (beta-hCG), in relation to preterm delivery Methods A cohort study of 9450 singleton pregnant women who attended the prenatal screening program at Aarhus University Hospital between January 2005 and December 2007, was conducted PAPP-A and free beta-hCG were measured in the first trimester. Early fetal growth was estimated by (GA(20) - GA(12))/Days(calendar), where GA(12) reflects the gestational age in days calculated from the crown-rump length at a 12-week scan, GA(20) reflects the gestational age in days calculated from the biparietal diameter at a 20-week scan, and Days(calendar) is the number of calendar days between the two scans. Results Low PAPP-A and low free beta-hCG were significantly associated with preterm delivery (<37 weeks) The association was even stronger when low PAPP-A and slow early fetal growth were combined, resulting in an adjusted odds ratio of 3 8 (95% CI, 1 6-8 7) Fast early fetal growth. but neither high PAPP-A nor high free beta-hCG, was significantly associated with preterm delivery. Conclusion Two different biological pathways leading to spontaneous preterm delivery are suggested fast early fetal growth and the combination of low PAPP-A and slow early fetal growth Copyright (C) 2010 John Wiley & Sons, Ltd.
