Suicide is a prevalent problem among veterans deployed to Iraq and Afghanistan. Traumatic brain injury (TBI) and psychiatric conditions, such as posttraumatic stress disorder (PTSD), are potentially important risk factors for suicide in this population, but the literature is limited by a dearth of research on female veterans and imprecise assessment of TBI and suicidal behavior. This study examined 824 male and 825 female U.S. veterans who were enrolled in the baseline assessment of the Veterans After-Discharge Longitudinal Registry (Project VALOR), an observational registry of veterans with and without PTSD who deployed in support of the wars in Iraq and Afghanistan and were enrolled in the Veterans Affairs healthcare system. Results indicated that current depressive symptoms, PTSD, and history of prior TBI were all significantly associated with current suicidal ideation (Cohen's d = 0.91, Cramers’ Vs = .19 and .08, respectively). After adding a number of variables to the model, including psychiatric comorbidity, TBI history was associated with increased risk of current suicidal ideation among male veterans only (RR = 1.55). TBI is an important variable to consider in future research on suicide among veterans of the wars in Iraq and Afghanistan, particularly among male veterans.

標題:伊拉克和阿富汗退役軍人中創傷性腦受損,PTSD和現存自殺念頭

撮要:從伊拉克和阿富汗退役的軍人中自殺是常見的問題,而創傷性腦受損(TBI) 和精神問題(如創傷後壓力症(PTSD))是其中潛在主要風險因素,但文獻中少有研究女退役人員,而TBI和自殺行為亦未見有準確評估。本文檢視824名男性和825名女性美國退役軍人,他們參與一個曾被派駐伊拉克和阿富汗戰事支援士兵(患上及非患上PTSD)的觀察名冊,即出院後退役軍人縱向檔案的基準評估(VALOR計劃),和接受退役軍人事務健康服務。結果顯示現存抑鬱症狀,PTSD和以前TBI 病史在統計學上與現存自殺念頭顯著相關 (Cohen's d=0.91, Cramers’ Vs= .19和.08)。加入一系列變量到模型中,包括精神病共病性,TBI 病史只與男性退役兵(RR=1.55) 現存自殺念頭的增加風險有相關。未來有關伊拉克和阿富汗戰事退役軍人(特別是男性)的自殺研究必須考量TBI 為一重要變量。
