[More cot deaths in child care settings than during the same hours at home: 10-year statistics].

Objective: To determine whether the incidence of sudden infant death syndrome (SIDS) in child care settings (child care centres or child minders) is different from that in the home setting, and to search for any differences in the prevalence of SIDS risk factors in both settings.
Design: Descriptive and comparative.
Method: All SIDS cases (< 2 years), that occurred between September 1996-August 2006 and known to the 'Landelijke Werkgroep Wiegendood' (the National Cot Death Study Group) of the Dutch Paediatric Association were analysed. The percentage of children involved in child care and the mean duration of their participation in child care, was calculated from national surveys carried out in well-baby clinics.
Results: In the 10 years of the study, 216 cases of SIDS became known to the Cot Death Study Group. In the first year of life, the number was 75% of the number registered by Statistics Netherlands. 28 of these infants died from SIDS between the ages of 3-6 months and on Monday-Friday between 8:00 am-5:00 pm: the usual hours of opening of child care facilities. Based on the uptake of child care during this period, 15% of this mortality was expected to have occurred in a child care setting and 85% at home. In reality, 61% (17/28) of the deaths occurred at a child care facility and 39% (11/28) at home. The relative risk was 8.8 (95% CI: 4.1-19.0). This high incidence of SIDS in a child care setting did not appear to be due to a higher prevalence of known risk factors for SIDS at child care facilities i.e. sleeping position (prone or side), passive smoking, heat congestion, or use of a quilt or pillow.
Conclusion: For infants aged 3-6 months, the relative risk ofSIDS during child care appeared to be increased 8.8 times (95% CI: 4.1-19.0) when compared with home settings in The Netherlands in September 1996-August 2006.
