This study examines the association between gun violence exposure (GVE) and suicidal ideation and behaviors among Black adults in the United States. Using a nationally representative sample of 3015 Black adults, the researchers found that exposure to GVE, including being threatened with a gun, knowing someone who has been shot, and witnessing or hearing about a shooting, was significantly associated with suicidal ideation and behaviors. Specifically, being threatened with a gun (odds ratio [OR], 1.44; 95% CI, 1.01-2.05) and knowing someone who has been shot (OR, 1.44; 95% CI, 1.05-1.97) were associated with reporting lifetime suicidal ideation. Being shot was associated with reporting ever planning a suicide (OR, 3.73; 95% CI, 1.10-12.64). Cumulative GVE was also associated with increased odds of reporting lifetime suicidal ideation, suicide attempt preparation, and attempting suicide. The findings suggest that reducing GVE may be crucial for addressing rising suicide rates among Black individuals in the US.This study examines the association between gun violence exposure (GVE) and suicidal ideation and behaviors among Black adults in the United States.
