About The Study: In this study of more than 2 million individuals born in Denmark, sibling death in childhood and early adulthood was associated with increased risks of overall and most type-specific early-onset cardiovascular diseases, with the strength of associations varying by cause of death and age difference between sibling pairs. The findings highlight the need for extra attention and support to the bereaved siblings to reduce cardiovascular disease risk later in life. 

Authors: Guoyou Qin, Ph.D., and Yongfu Yu, Ph.D., of Fudan University in Shanghai, China, are the corresponding authors.
