Suicides among U.S. Army soldiers are increasing and, in January 2009, outpaced deaths due to combat. For this study, 1,873 army suicides identified through death, inpatient, and emergency room records were matched with 5,619 controls. In multivariate models, older, male, White, single, and enlisted soldiers with a prior injury (OR = 2.04, 95% CI = 1.64-2.54), alcohol (OR = 3.41, 95% CI = 2.32-4.99), or mental health hospitalization (OR = 6.62, 95% CI = 4.77-9.20) were at increased risk for suicide. Risk was greatest immediately following diagnoses, but remained elevated even after 5 or more years of follow-up. Most injury hospitalizations were unintentional but, nonetheless, significantly associated with suicide. Interactions indicate soldiers with both mental health and injury history are particularly vulnerable.
美国陆军士兵的自杀率正在上升，2009 年 1 月，自杀人数超过了战斗伤亡人数。在这项研究中，通过死亡、住院和急诊记录确定了 1873 例陆军自杀事件，并与 5619 名对照者进行了匹配。在多变量模型中，年龄较大、男性、白人、单身、入伍士兵，以及有既往受伤（OR=2.04，95%CI=1.64-2.54）、酒精（OR=3.41，95%CI=2.32-4.99）或精神健康住院（OR=6.62，95%CI=4.77-9.20）的士兵自杀风险更高。风险在诊断后立即增加，但即使在 5 年或更长时间的随访后仍保持较高水平。大多数受伤住院是意外发生的，但尽管如此，仍与自杀显著相关。交互作用表明，有精神健康和受伤史的士兵特别容易受到影响。
