Does Death of Siblings in Childhood Increase Death Risk of Surviving Children?

Loss of same-sex sibling or sibling with closer age, increases the likelihood of death among surviving children.

Death of a sibling during childhood increases risk of death among surviving children from all causes, in both the short and long term, according to a new article published by JAMA Pediatrics.

Nearly 8 percent of individuals in the //United States are estimated to have experienced a sibling dying in childhood.

‘Increased awareness and social support should be provided to bereaved siblings to reduce the level of grief and minimize any potential adversity that could affect their health.’

Yongfu Yu, Ph.D., of Aarhus University Hospital, Denmark, and coauthors conducted a population-based study that included more than 5 million Danish and Swedish children who survived the first six months of life. Death of a sibling was experienced by 55,818 (1.1 percent) in childhood (from six months after birth until 18) and the median age was 7 at sibling loss. During a follow-up of 37 years, 534 individuals in this bereaved group died.

Compared with those who did not experience the death of a sibling, the bereaved group had a 71 percent increased risk of death from all causes. The increased risk of death after a sibling's death was seen across the follow-up but higher risks of death were found in the first year after a sibling's death, as well as among same-sex sibling pairs or siblings with a small age difference, according to the results.

Limitations of the study include a lack of data on social environment and family characteristics which might help explain underlying reasons that link sibling death and increased risk of death for the bereaved sibling. Other factors may also exert influence over the associations researchers have detailed.

"Health care professionals should be aware of children's vulnerability after experiencing sibling death, especially for same-sex sibling pairs and sibling pairs with close age. Social support may help to reduce the level of grief and minimize potential adverse health effects on the bereaved individuals," the article concludes.
