Prevention of Sudden Infant Death Syndrome (SIDS) in Bavaria - evaluation of a prevention campaign. 
With simple prevention measures SIDS (Sudden Infant Death Syndrome) incidence rates can be reduced.  A cross-sectional survey in Bavaria in 2005 showed that maternity units fall short in acting as role models and informing parents regarding SIDS prevention and that parents did not sufficiently apply prevention measures.  An information campaign in Bavaria was initialized and evaluated after 18 months.  Flyers and posters for SIDS prevention using consistent information were developed for dissemination by the relevant occupational groups.  The campaign impact was assessed in repeating the cross-sectional survey.  A response rate of 99% for the maternity units and 60% for the parent questionnaires could be achieved.  Significant improvements (p<0.05) in the maternity units regarded a higher proportion of parents informed about SIDS prevention measures (97 vs. 92%) and an increased use of sleeping bags (37 vs. 12%), whereas the proportion of children placed in supine position to sleep was not increased.  More parents reported to have obtained advice for SIDS prevention (83 vs. 73%) and to have used sleeping bags (66 vs. 56%).  A subgroup analysis revealed poorer information and implementation of the recommendations in families with three or more children and less educated families.  After initiation of the information campaign reported knowledge about SIDS prevention measures increased.  Continuing shortfalls exist regarding maternity units acting as role models and implementation of the recommendations by the parents.  Future interventions should focus in particular on the role model function of maternity units and target groups.
