A descriptive and prospective study on the multiple pregnancies occurred at "Julio Alfonso Medina" Gynecoobstetric Hospital, in Matanzas, in 2000, was conducted. The sample was composed of all the pregnancies of this type with more than 28 weeks and delivery occurred in the above mentioned hospital. The influence of these pregnancies on the main indicators of morbidity and perinatal mortality was studied. Of a total of 3 022 births, for an incidence of 1.12 %, 34 were multiple pregnancy, 33 were twins and one was triplets. 91.1 % of the pregnant women had obstetric diseases, such as arterial hypertension, early rupture membrane and anemia. There was predisposition to cesarean section when the presentations were not cephalic, or cephalic-pelvic. The second twin had low birth weight more frequently. The results were expressed by percentage and the average values were calculated. The X2 test with a ³ 0,05 was also applied.
