Vietnam veterans have been reported to be at increased risk for posttraumatic stress disorder (PTSD) and deaths due to traumatic causes after service in the Vietnam War. This study evaluated whether an association exists between PTSD and traumatic deaths among Vietnam veterans. Mortality risk of 4,247 Vietnam veterans from the Agent Orange Registry (AOR) with a diagnosis of PTSD relative to that of 12,010 Vietnam veterans from the AOR with no diagnosis of PTSD was calculated using the Cox proportional hazards model. Mortality experience of both groups was also compared with U.S. males. The PTSD veterans were more likely than the non-PTSD veterans to die from suicide (relative risk = 3.97, 95% confidence interval [CI] = 2.20-7.03) and from accidental poisoning (relative risk = 2.89, CI = 1.03-8.12). The standardized mortality ratio for suicides was 6.74 (CI = 4.4-9.87) among PTSD veterans and 1.67 (CI = 1.05-2.53) among non-PTSD veterans. Among Vietnam veterans on the AOR, PTSD is associated with a significant increased risk for suicide and accidental poisoning.
据报道，越战退伍军人在越战服役后患创伤后应激障碍（PTSD）以及因创伤原因死亡的风险有所增加。本研究评估了越战退伍军人中PTSD与创伤性死亡之间是否存在关联。使用Cox比例风险模型计算了来自橙剂登记处（AOR）的4247名被诊断患有PTSD的越战退伍军人相对于12010名未被诊断患有PTSD的AOR越战退伍军人的死亡风险。还将两组的死亡情况与美国男性进行了比较。患有PTSD的退伍军人比未患PTSD的退伍军人更有可能死于自杀（相对风险=3.97，95%置信区间[CI]=2.20-7.03）和意外中毒（相对风险=2.89，CI=1.03-8.12）。PTSD退伍军人的自杀标准化死亡率为6.74（CI=4.4-9.87），未患PTSD的退伍军人为1.67（CI=1.05-2.53）。在AOR的越战退伍军人中，PTSD与自杀和意外中毒的显著风险增加有关。
