136 infants died of sudden infant death syndrome (SIDS) and 140 infants died suddenly and unexpectedly from life-threatening conditions (LTC) from 1983 to 1989 in Leningrad entered the study. 24-hour distribution of death cases was evaluated in both studied groups. The increased incidence of SIDS was revealed from 04(00) to 06(00). There was not significant difference between circadian variation of SIDS and that of death from LTC. The early morning seems to be the time when the risk factors that lead to sudden death are likely to be prominent.
