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.journal articlemetadata only access51-76Perinatal anthropometryTwins fetal growthTwins newborn.
