The association between suicide and combat injuries sustained during the wars in Iraq and Afghanistan was examined. A retrospective population-based cohort design was conducted using official military records to identify combat injuries (October 7, 2001, to December 31, 2007). Those who were injured during combat had higher crude suicide rates than those who deployed and were not injured (incidence rate ratio [IRR] = 1.50; confidence interval [CI] = 1.06, 2.12), or never deployed (IRR = 1.46; CI = 1.04, 2.06). After adjusting for demographics, these findings were no longer statistically significant. Although our data did not support an elevated suicide risk among wounded service members, additional research is needed to examine the impact of injury severity.
对伊拉克战争和阿富汗战争期间自杀与战斗受伤之间的关联进行了研究。采用基于人群的回顾性队列设计，利用官方军事记录来确定战斗受伤情况（2001年10月7日至2007年12月31日）。在战斗中受伤的人员的粗自杀率高于那些部署但未受伤的人员（发病率比[IRR]=1.50；置信区间[CI]=1.06, 2.12），或高于从未部署过的人员（IRR=1.46；CI=1.04, 2.06）。在对人口统计学因素进行调整后，这些发现不再具有统计学意义。虽然我们的数据不支持受伤军人的自杀风险升高，但仍需要进一步研究来考察损伤严重程度的影响。
