i. i. customary to esti.ate the uteroplacental functi.n i. si.gletons by defi.i.g appropri.teness of bi.th wei.ht by gestati.nal age. Such a measure,however,i. not avai.able for the enti.e multi.le pregnancy set. We evaluate a new i.dex,total tri.let bi.thwei.ht,expressed as multi.les of the medi.n (MOM) bi.th wei.ht of si.gleton gestati.ns. We categori.ed tri.let sets as small-,appropri.te-,and large-for-gestati.nal age pregnanci.s (SGA,AGA,and LGA,respecti.ely),defi.ed as1 SD from the mean MOM bi.th wei.ht of si.gleton gestati.ns. We used the 1995-1998 US matched multi.le dataset to evaluate thi. i.dex and to explore the associ.ti.n between the three categori.s i. terms of ri.k of neonatal mortali.y. The mean ±SD MOM value was 2.3 ±0.4. There was an i.verse correlati.n between mean MOM and gestati.nal age. LGA pregnancy status was associ.ted wi.h multi.ari.y,race (bei.g whi.e),and hi.h soci.l status (educati.n). Maternal age di. not i.fluence MOM scores. Compared wi.h the LGA pregnancy category,the ri.k for neonatal mortali.y was more than doubled i. the AGA pregnancy group and more than 9-fold i. the SGA pregnancy category. We propose that thi. new measure could be a useful proxy for the uteroplacental effi.i.ncy i. a si.i.ar way that the SGA desi.nati.n works for si.gleton i.fants.

Objecti.e:The purpose of thi. study was to calculate the prospecti.e ri.k of fetal death i. monochori.ni.-di.mni.ti. twi.s. Study desi.n:We evaluated 193 monochori.ni. di.mni.ti. twi. pregnanci.s that were followed and deli.ered after 24 weeks. Survei.lance i.cluded cardi.tocography and sonography performed at least once weekly. The prospecti.e ri.k of fetal death was calculated as the total number of deaths at the begi.ni.g of the gestati.nal peri.d di.i.ed by the number of conti.ui.g pregnanci.s at or beyond that peri.d. Results:The fetal death rate was 5 of 193 pregnanci.s (2.6%; 95%Ci.1.1,5.9); the prospecti.e ri.k of sti.lbi.th per pregnancy after 32 weeks of gestati.n was 1.2%(95%Ci.0.3%-4.2%). Conclusi.n:Under i.tensi.e survei.lance,the prospecti.e ri.k of fetal death i. monochori.ni.-di.mni.ti. pregnanci.s after 32 weeks of gestati.n i. much lower than reported and does not support a poli.y of electi.e preterm deli.ery.
