About The Study: In this study of more than 2.6 million births in Denmark between 1978 and 2016, a higher rate of sudden infant death syndrome (SIDS) was observed among siblings of children who died of SIDS compared with the general population. Shared genetic and/or environmental factors may contribute to the observed clustering of SIDS. The family history of SIDS should be considered when assessing SIDS risk in clinical settings.
