OBJECTIVE: To characterize and compare (he pregnancy complications occuring in twin, triplet, and quadruplet gestations. STUDY DESIGN: Using a data set linking birth certificates with maternal and newborn hospital discharge records from acute care civilian hospitals in California, all twin, triplet, and quadruplet gestations were identified. Specific pregnancy characteristics and the incidence of antepartnm complications were analyzed and compared among the three groups. RESULTS: The incidence of multiple gestations was 2.2% in the population of 571,390 deliveries. Hypertensive complications occurred 2.5 times more often in triplet gestations as compared to twins (17.5% vs 7.4%, p < 0.01). The incidence of gestational diabetes was 2.8%, in twin pregnancies and increased exponentially with higher order gestations to a maximum of I5.H% in quadruplets. (ANOVA, p < 0.001 ). Antepartum bleeding, preterm prematuie rupture of the membranes, and post part urn hemorrhage were not significantly increased over the rates reported in singleton gestations. Pregnancy characteristics are shown below.
