BACKGROUND. In the last 20 years, the prevention campaigns to reduce the risk of
sudden infant death syndrome were very successful. In some countries the advice to
breastfeed is included in the campaigns’ messages, but in other countries it is not.
OBJECTIVE. To examine the association between type of infant feeding and sudden
infant death syndrome.
METHODS. The German Study of Sudden Infant Death is a case-control study of 333
infants who died of sudden infant death syndrome and 998 age-matched controls.
RESULTS.A total of 49.6% of cases and 82.9% of controls were breastfed at 2 weeks of
age. Exclusive breastfeeding at 1 month of age halved the risk, partial breastfeeding
at the age of 1 month also reduced the risk of sudden infant death syndrome, but
after adjustment this risk was not significant. Being exclusively breastfed in the last
month of life/before the interview reduced the risk, as did being partially breastfed.
Breastfeeding survival curves showed that both partial breastfeeding and exclusive
breastfeeding were associated with a reduced risk of sudden infant death syndrome.
CONCLUSIONS. This study shows that breastfeeding reduced the risk of sudden infant
death syndrome by 50% at all ages throughout infancy. We recommend including
the advice to breastfeed through 6 months of age in sudden infant death syndrome
