The current study investigated whether sufficient attendance at prenat
al and postnatal checks affects the risk of sudden infant death syndro
me. A case-control study in the Tyrol enrolled 99 infants with sudden
infant death syndrome that occurred between 1984 and 1994, and 136 ran
domly selected control cases. The risk of sudden infant death syndrome
was higher in infants whose mothers attended less than five antenatal
health checks than in the group with at least five or more visits (OR
5.1; p < 0.01), Babies who received medical help beyond routine healt
h controls had a lower risk than those who did not (OR 0.32; p < 0.001
). These differences persisted when social and demographic variables (
mother's age at delivery, educational level, marital status, parity an
d gestational age) were taken into account. Our study identified inade
quate antenatal and postnatal care as a risk indicator for sudden infa
nt death syndrome and as a potential target for further educational wo
rk. Clinical recommendations should await the results of further evalu
ations.
