  Objective: To compare the infant mortality rate (IMR) due to sudden infant death syndrome (SIDS) in twins and singletons and consider the risk factors of SIDS. Materials and methods: The IMR due to SIDS was analyzed among twins and singletons from 1995 to 2008 using the Japanese Vital Statistics. Results and discussion: The IMR for both twins and singletons decreased (1/3-1/4) significantly during 1995- 2008 and was significantly higher among twins than in singletons during 1995-2000 and 2003-2004. The relative risks of SIDS for maternal age groups between <25 years and 30–34 years were 9-fold for twins and 3-fold for singletons. The IMR increased with parity for both 1st- and 2nd-twin born. Seasonal variations were observed in IMRs for twins and singletons. The time of death from 4 a.m. to 7 a.m. was a risk factor for SIDS in twins and singletons. .. View More»
