Abstract
Analysis of singleton preterm birth from vital statistics data is hamp ered by inaccurate gestational age dating. This is most notably eviden ced by the large fraction of implausibly high birthweights for gestati onal age given in birth records. Using natality statistics for New Eng land, 1977-88, birthweight distributions were plotted for representati ve preterm gestations. Confounding by improbable birthweights was obse rved to be considerably less among preterm twin births than among pret erm singleton births.
