Dummy use, thumb sucking, mouth breathing and cot death

In the Netherlands a case control study into cot death was undertaken as pa rt of the European Concerted Action on sudden infant death syndrome. Childr en between week and 2 years of age who died suddenly and unexpectedly were reported. Non cot death cases were excluded after a consensus by three path ologists. The study comprised 73 cot death cases and two controls per case, matched for date of birth. Compared to national data, the coverage was 91% . We investigated whether in the Netherlands new risk or preventive factors might have emerged. The present report focuses on the relative risks of du mmy use. thumb sucking, breast versus bottle feeding, and sleeping with the mouth open. Conclusion Dummy use seems to be an important preventive factor for cot dea th in the Netherlands. independent of other risk factors such as prone slee ping and bedding. We recommend dummy use at least for bottle-fed infants. W e found no indication that dummies influence the frequency or duration of b reast feeding but more data are needed. Mouth breathing appears to be assoc iated with an increased risk for cot death, but again further research is n eeded.
