Using vital statistics in Japan (1995–2008), 154,578 live-born twin pairs (128,236 monozygotic [MZ] and 180,920 dizygotic [DZ]) were identified. The proportion of severe discordance among live-born twin births was twice as high in Japanese than Cau

The infant mortality rate (IMR) among single and twin births from 1999 to 2008 was analyzed using Japanese Vital Statistics. The IMR was 5.3-fold higher in twins than in singletons in 1999 and decreased to 3.9-fold in 2008. The reduced risk of infant

Objective: We aimed to determine the perinatal mortality rates (PMRs) for monozygotic (MZ) twins, dizygotic (DZ) twins, and singletons, together with the associated risk factors for these PMRs. Study design: PMRs of zygotic twins and singletons were

We aimed to determine the Stillbirth Rates (SRs) for monozygotic (MZ) and dizygotic (DZ) twins, with the risk factors for stillbirth. SRs were estimated using Japanese vital statistics from 1995 to 2008. The SRs of zygotic twins significantly decreas
