Nomogram and development of basic and advanced fetal growth customized modelsART-2015-92346We have performed a multivariate analysis to explore the influence on birth and ultrasound fetal weight estimation of traditional factors as biochemical data and maternal characteristics in combination with non- traditionally explored predictors as paternal height, Pregnancy-associated plasma protein A (PAPP-A), single umbilical artery or Free-beta Human Chorionic Gonadotropin (fß- HCG). The study was performed for a Spanish population (region of Aragon) in singleton pregnancies at term (37-42 weeks). Also, we have created a nomogram and in order to predict the occurrence of SGA (small for gestational age) and LGA (large for gestational age) cases we provide a multivariate predictive model of fetal weight that have been compared with other models in the prediction of ultrasound and birth weights. After study we have created a software application for automated calculation of percentile fetal weight, adjusting the variables when they were significant.2015http://zaguan.unizar.es/record/3221510.1515/jpm-2015-2002http://zaguan.unizar.es/record/32215oai:zaguan.unizar.es:32215JOURNAL OF PERINATAL MEDICINE 43, S1 (2015), O-0009 [1 p.]by-nc-ndhttp://creativecommons.org/licenses/by-nc-nd/3.0/es/info:eu-repo/semantics/openAccess
