Triple-Risk Model of SIDS

1. Intrinsic risk factors

• Genetic

• Male sex
• Polymorphism in the gene encoding the promoter region of the serotonin transporter
• Black or Native American race or ethnic group

• Developmental

• Prematurity

• Environmental

• Perinatal exposure to smoking
• Parental smoking, ethanol intake, or drug use
• Socio-economic disadvantage

2. Extrinsic risk factors

• Sleeping on the side or in prone position
• Soft bedding
• Bed sharing
• Mild infections, including colds

Recommendations for Risk Reduction and Counseling

• Putting infants to bed in the supine position on a firm mattress, preferably with a pacifier and in a shared room (but in a separate bed).
• Prone and side sleeping, overheating, bed sharing, soft bedding, and smoking by mothers during pregnancy or around infants should be avoided.
• Home cardio-respiratory monitoring of apnea and bradycardia is not recommended because it has not been shown to prevent SIDS.
