Studies of completed suicide by history of military service have produced inconsistent findings; no representative population-based study has compared the risk of nonfatal suicidal behavior among veterans with risk among nonveterans. The objective of this study was to examine whether male veterans of the U.S. military are at heightened risk of suicidal ideation, compared with males who never served in the U.S. military. A total of 17,641 adult men completed the 2008 National Survey on Drug Use and Health (NSDUH). Subjects provided information about history of ever having served in the U.S. armed forces, past suicidal ideation, alcohol and drug abuse and dependence, measures of psychological distress, and sociodemographic data. Overall, men who had ever served in the armed forces were no more likely than men who had never served to report having seriously considered suicide over the prior 12 months. Military status was not differentially associated with other known suicide risk factors assessed by NSDUH, including psychiatric disorders. Our findings suggest that evidence-based suicide prevention strategies applicable to the general population should be employed to reduce suicide risk among the veteran population as well.
关于兵役史与自杀的研究结果并不一致；尚无代表性的基于人群的研究比较过退伍军人与非退伍军人之间非致命性自杀行为的风险。本研究旨在调查与从未服过兵役的男性相比，美国男性退伍军人是否更有可能出现自杀意念。共有 17641 名成年男性完成了 2008 年全国药物使用与健康调查（NSDUH）。调查对象提供了有关是否曾在美国武装部队服役、过去是否有过自杀意念、酒精和药物滥用及依赖、心理困扰程度以及社会人口统计学数据等信息。总体而言，有过兵役经历的男性与从未服过兵役的男性报告在过去 12 个月内曾认真考虑过自杀的可能性一样大。兵役状况与 NSDUH 评估的其他已知自杀风险因素（包括精神障碍）并无差异相关。我们的研究结果表明，应采用适用于普通人群的循证自杀预防策略，以降低退伍军人人群的自杀风险。
