Perinatal indicators of sudden infant death syndrome: A study of 34 Rhode Island Cases

Pre- and perinatal characteristics of 34 victims of Sudden Infant Death Syndrome (SIDS) were compared with those controls matched for sex, race, birthdate, and hospital. Data were collected retrospectively from hospital records. Factors which reliably differentiated the SIDS group from controls included low birth-weight, short second stage of labor, fewer years of maternal schooling, and maternal anemia during pregnancy. The constellation of findings was interpreted as reflecting the interaction of physiological predispositions and environmental “setting conditions”, culminating in sudden and unexpected death. The efficacy of a previously established SIDS risk scale was assessed for these cases. Some issues concerning prediction of outcome from perinatal variables are discussed.
