[BDSP. Notice produite par INIST-CNRS D9R0xpGA. Diffusion soumise à autorisation]. Objectives. We assessed the risk of suicide among veterans compared with nonveterans. Methods. Cox proportional hazards models estimated the relative risk of suicide, by self-reported veteran status, among 500822 adult male participants in the National Death Index (NDI) - linked National Health Interview Survey (NHIS), a nationally representative cohort study. Results. A total of 482 male veterans died by suicide during 1 837 886 person-years of follow-up (76 % by firearm) ; 835 male nonveterans died by suicide during 4438 515 person-years of follow-up (62 % by firearm). Crude suicide rates for veterans and nonveterans were, respectively, 26.2 and 18.8 per 100000 person-years. The risk of suicide was not significantly higher among veterans, compared with nonveterans, after adjustment for differences in age, race, and survey year (hazard ratio =1.11 ; 95 % confidence interval =0.96,1.29). Conclusions. Consistent with most studies of suicide risk among veterans of conflicts before Operation Iraqi Freedom/Operation Enduring Freedom, but in contrast to a previous study using the NDI-linked NHIS data, we found that male veterans responding to the NHIS were modestly, but not significantly, at higher risk for suicide compared with male nonveterans.
