Newborn (RN) twin is at high risk for morbidity and mortality. It is classified with intrauterine growth curves (CCIU) single fetuses, but no Peruvian curves for this group. To determine the intrauterine growth of a selected group of Peruvian twins and compare RN unique patterns. MATERIALS AND METHODS: Descriptive, transversal study for 13 years (1992-2004) in the Hipolito Unanue Hospital in Tacna, Peru. 518 twins, 282 twins (54%) was selected without factors qie altered intrauterine growth. averages, standard deviation and percentiles 10, 50 and 90 of weight, height and head circumference was found for gestational age of 32-41 weeks, which were corrected with second order polynomial. Average percentile values and unique curvy compared RN, were considered significant when p <0.05. RESULTS: Of 36 909 live births, 518 were twins, which was selected 282. The most representative group was 38...
