Sumario:Introduction The use of local references or standard for neonatal studies still requires their validation through indicators of morbidity and mortality. Objective: evaluate the performance of the INTERGROWTH-21st Project (IG-21) standard and a commonly used Argentinian reference (Urquia) by examining the differences in the frequency of growth phenotypes, and the associated neonatal morbidity and mortality. Methods: Retrospective cohort study of all singleton live-births from Sarda Maternity Hospital (Buenos Aires, Argentina) between 33 and 42 gestational age, using information obtained from a Perinatal Surveillance System (Agustina) dataset between 1996-2001 (n = 25948). Phenotypes small- and large-for-gestational age, stunting and waisting and a composite of neonatal morbidity/mortality (CNMM) were contrasted between the IG-21 standard and Urquia reference. Results: the Urquia 3rd centile value was lower than IG-21 before 37 weeks, but then it surpassed IG-21 until term. Among Sarda , 2.3%, 5.9% and 8.9 were <3rd, <10th and >97th centile, respectively, under the IG-21 standard, while 3.7%, 10.1% and 8.4% were <3rd, <10th and >97th centile, respectively, under the Urquia reference. Stunting and waisting were 16.1% and 0.9%, respectively under IG-21. The IG-21 detection rates of CNMM showed that 28.5%, 19.6% and 8.5% occurred among weight<3rd,<10th and >97th centile, respectively, while 21.8%, 14.2% and 8.0%  occurred among <3rd, <10th and >97th centile under the Urquia criteria. Newborn weight <3rd,<10th and >97th  centile under IG-21 showed higher neonatal CNMM risk compared with Urquia reference. Conclusions: The IG-21 standard identified a higher risk of neonatal morbidity and mortality than the Urquia reference.
