The finding that prone sleeping position and smoking are important risk factors for SIDS has considerably reduced the incidence. Although these risk factors can be found in many cases of SIDS, they cannot be regarded as causes of death. CONCLUSION: The diagnosis of SIDS must be adhered to, and risk factors must not be confused with diagnoses. A structured follow-up of all cases of SIDS can be a cost-effective mean to ensure that parents and researchers are given adequate information.
