The percentage of "143,747 suicide decedents in National Violent Death Reporting System" from 2020-2023 who "were reported to have physical health problems as a precipitating circumstance for suicide," according to an article in the American Journal of Preventive Medicine -- Physical Health Conditions Among Suicide Decedents: National Violent Death Reporting System, U.S., 2020–2023.

Nearly one quarter of suicide decedents with physical health problems experienced chronic pain, and almost half had at least 1 chronic condition. Decedents with physical health problems were significantly older (x̄=63.3 vs x̄=42.9 years), more likely to have ever served in the military (26.1% vs 12.3%), less likely to have a mental health diagnosis (43.8% vs 50.5%), and more likely to have disclosed current suicidal thoughts or intent (22.6% vs 20.9%; p<0.001) than those without physical health problems.
