Suicide ideation, plans, and attempts among military veterans vs nonveterans with disability

Objective  To evaluate whether veteran status is associated with greater risk for suicide in those with disability. Design, Setting, and Participants  This survey study used cross-sectional self-reported data from US adults who participated in the 2015-2020 National Survey on Drug Use and Health. Data were weighted to represent the population. Data analysis was conducted from July to August 2022. Main Outcomes and Measures  Suicide ideation, planning, and attempt served as primary outcomes. Disability status (present or absent) and number of disabling limitations (1, 2, or ≥3) served as factors. Veteran status was determined based on self-report (veteran or nonveteran). Multivariable logistic regression examined suicide ideation, planning, and attempt as a function of veteran status and disability variables. Results  Participants included 231 099 US veterans and nonveterans, representing 236 551 727 US adults, of whom 20.03% (weighted n = 47 397 876) reported a disabling limitation, 8.92% were veterans (weighted n = 21 111 727; 16.0% aged 35-49 years; 91.0% men; 6.7% Hispanic; 10.9% non-Hispanic Black; and 78.4% non-Hispanic White) and 91.08% were nonveterans (weighted n = 215 440 000; 25.4% aged 35-49 years; 44.0% male; 16.5% Hispanic; 11.7% non-Hispanic Black; and 63.3% non-Hispanic White). Overall, 4.39% reported suicide ideation, planning, or attempt (weighted n = 10 401 065). Among those with no disability, veteran status was associated with higher risk of suicide planning (adjusted odds ratio [AOR], 1.71; 95% CI, 1.17-2.49). Among those with 1 or 2 disabling limitations, being a veteran was associated with a lower risk of suicide planning (AOR, 0.57; 95% CI, 0.34-0.95) and history of attempt (AOR, 0.46; 95% CI, 0.24-0.88). Conclusions and Relevance  In this study of how suicide risk differs as a function of disability and veteran status, risk for death by suicide was lower among veterans with disability relative to nonveterans with disability. Veteran status may mitigate risk for suicide given increased receipt of more disability-related care through the Department of Veterans Affairs. Further research would extend this line of inquiry by examining the cause and type of disability as well as perceptions of disability on self-worth. It is possible that physical wounds of war are protective because of the meaning and value of service to one’s country.
