Nonetheless, many modifiable and non-modifiable risk factors for infant sudden death syndrome are surprisingly similar to the ones for asphyxia.Purpose: To carry out a literature search and review regarding infant sudden death syndrome and environmental factors potentially related to it.Method: A literature search was performed by means of the Andalusia\'s Public Health System meta-search engine Gerion. Search terms were "infant sudden death syndrome" and "environment". Data were collected by a single researcher.Results and conclusions: 11 papers were selected and assessed.Reported recommendations include: sleeping in supine position, use of a pacifier and a flat surface when sleeping; promoting breast feeding; systematic immunization; sleeping together and not sharing bed; avoid soft bed clothes, overheating, and smoking, alcohol, illicit drugs, and smoke exposure.
