Example citation

The increased risk of suicide within families of suicide decedents is primarly explained by a shared genetic etiology, but shared environment factors also play a role

Key takeaways

  • OR full siblings = 3.1 (95% CI 2.8 - 3.5)
    • OR half siblings = 1.7 (1.1 - 2.7)
  • three

Familial clustering of suicide is primarily influenced by genetic and also shared environmental factors. The family history of suicide should be considered when assessing suicide risk in clinical settings or designing and administering preventive interventions.
