QUESTION
What is the prevalence of head covering and associated risk of sudden infant death syndrome (SIDS)?
REVIEW SCOPE
Included studies reported prevalence of head covering in SIDS infants and control infants waking from a reference sleep. Studies that did not separate head covering from other facial occlusion or that only reported results for SIDS infants were excluded. Outcome was prevalence of head covering.
REVIEW METHODS
Medline, customised databases, and reference lists were searched for age-matched case-controlled studies from 1950 to May 2007. 10 studies (n = 7718) met the selection criteria.
MAIN RESULTS
SIDS infants had a higher pooled prevalence of head covering than control infants (table). The adjusted odds ratio for SIDS death was 17. Head covering was associated with increased risk of SIDS (population attributable risk 27%, 95% CI 25 to 29).
CONCLUSION
Head covering is associated with increased risk of sudden infant death
