  1. The changing pattern of multiple births in the United States : maternal and infant characteristics, 1973 and 1990.

    Article - En anglais


    To evaluate changes in the incidence and proportion of live births by plurality in the United States between 1960 and 1990, and to compare the distribution of singleton, twin, and triplet and higher-order births (triplet+) by maternal and infant characteristics for 1973 and 1990.


    Vital statistics data were used to conduct a population-based analysis of all live births from 1960-1990 and to compare changes in the incidence and outcomes of live births between 1973 and 1990 by maternal and infant characteristics.


    Between 1960 and 1973, the number of twin births paralleled that of singletons, whereas the number of triplet+births remained fairly constant.
