The incidence of SIDS in western countries has decreased since the late 1980s after active SIDS prevention campaigns. By contrast, both Taiwan and Japan have reported an increase in incidences. In this report data from England, Wales, Scotland, Northern Ireland, Japan and Hong Kong are analysed. Regression coefficient and linearity of regression tests were used to determine if there was any significant increase or decrease in post-neonatal mortality (PNNM), SIDS mortality and mortality among infants 1-5 months old. A statistically significant decrease in SIDS was recognized in England, Wales, Scotland and Northern Ireland, whereas statistically significant increases were noted for Japan and Hong Kong. However in Japan and Hong Kong both the PNNM and mortality of infants between 1-5 months in age fell significantly, suggesting that the increased SIDS rates could be due to a change in diagnostic labelling. Further study will be required to determine whether this increase in the incidence of SIDS is genuine or only an artifact.
