RT Journal Article T1 Crecimiento intrauterino de los gemelos: Tablas y curvas percentiladas, por sexo y edad gestacional T2 Intrauterine twins growth percentiled curves and graphs according to sex and gestational age A1 Alonso Ortiz, T. A1 Armada Maresca, María Isabel A1 Alonso Chacón, Pablo A1 Zuluaga Arias, María del Pilar AB Objective: to elaborate twin intrauterine growth curves and standard graphics according to sex and gestational age and perinatology facts of these gestations. Material and methods: to study anthropometry at birth (weight, height and head circumference) of 1116 couples of twins born at Hospital Clínico San Carlos de Madrid. A transversal descriptive analysis has been used. Results: growth curves and graphics of 1056 healthy male twins and 1086 healthy female twins coming from non patology pregnancies with percentiled (3,10,25,50,75,90,97) are shown. Conclusions: each population group must have their own fetal growth curves so we can clasify newborns in preterm, in term and post-term and in big, normal and small acording to gestational age.
