The Department of Veterans Affairs previously conducted a proportionate mortality study of Army and Marine Vietnam-era veterans who died during 1965 through 1982. In the present study, 11,325 veterans who died during 1982 through 1984 and 50,743 veterans from the previous analysis made up the final sample of 62,068 veterans. When compared with all non-Vietnam veterans, Army Vietnam veterans had statistically significant excesses of deaths from external causes (proportionate mortality ratio [PMR] = 1.03), laryngeal cancer (PMR = 1.53), and lung cancer (PMR = 1.08). Marine Vietnam veterans had a significantly elevated PMR for external causes (PMR = 1.06) with a significant excess of homicide deaths (PMR = 1.16) when compared to all non-Vietnam veterans. The elevated PMRs for lung cancer and non-Hodgkin's lymphoma among Marine Vietnam veterans reported in the earlier VA study persisted when compared with Marine non-Vietnam veterans. However, it was found that these elevations probably were due to a deficit among the Marine non-Vietnam veterans rather than an excess among Marine Vietnam veterans.
美国退伍军人事务部此前对1965年至1982年期间死亡的陆军和海军陆战队越战时期退伍军人进行了一项比例死亡率研究。在本研究中，1982年至1984年期间死亡的11325名退伍军人和之前分析中的50743名退伍军人构成了最终样本，共计62068名退伍军人。与所有非越战退伍军人相比，陆军越战退伍军人在外因导致的死亡（比例死亡率[PMR]=1.03）、喉癌（PMR=1.53）和肺癌（PMR=1.08）方面存在统计学上显著的超额死亡。与所有非越战退伍军人相比，海军陆战队越战退伍军人在外因导致的死亡方面比例死亡率显著升高（PMR=1.06），其中凶杀死亡显著超额（PMR=1.16）。与海军陆战队非越战退伍军人相比，退伍军人事务部早期研究报告的海军陆战队越战退伍军人肺癌和非霍奇金淋巴瘤的比例死亡率升高情况仍然存在。然而，研究发现，这些升高可能是由于海军陆战队非越战退伍军人中的不足，而不是海军陆战队越战退伍军人中的超额。
