The U.S. Army suicide rate increased sharply during the wars in Iraq and Afghanistan. There is limited information about medically documented, nonfatal suicidal behaviors among soldiers in the Army's Reserve Component (RC), which is composed of the Army National Guard and Army Reserve. Here we examine trends and sociodemographic correlates of suicide attempts, suspicious injuries, and suicide ideation among activated RC soldiers.
Data come from the Army Study to Assess Risk and Resilience in Servicemembers (Army STARRS) Historical Administrative Data Study (HADS), which integrates administrative records for all soldiers on active duty for the years 2004 through 2009 (n = 1.66 million).
We identified 2,937 unique RC soldiers on active duty with a nonfatal suicidal event documented at some point during the HADS study period. There were increases in the annual incidence rates of suicide attempts (71 to 204/100,000 person-years) and suicide ideation (326 to 425/100,000 person-years). Incidence rates for suspicious injuries also generally increased but were more variable. Using hierarchical classification rules, we identified the first instance of each soldier's most severe behavior (suicide attempt versus suspicious injury versus suicide ideation). For each of those suicide- or injury-related outcomes, we found increased risk among those who were female, younger, non-Hispanic White, less educated, never married, and lower-ranking enlisted. These sociodemographic associations significantly differed across outcomes, although the patterns were similar.
Results provide a broad overview of nonfatal suicidal trends in the RC during the period 2004 through 2009. They also demonstrate that integration of multiple administrative data systems enriches analysis of the predictors of such events.
在伊拉克和阿富汗战争期间,美国陆军自杀率急剧上升。关于陆军后备役部队(RC,由陆军国民警卫队和陆军后备队组成)士兵中经医学记录的非致命自杀行为的信息有限。在此,我们研究现役后备役部队士兵自杀未遂、可疑伤害和自杀意念的趋势及社会人口学相关因素。
数据来自陆军评估军人风险与恢复力研究(陆军STARRS)历史行政数据研究(HADS),该研究整合了2004年至2009年所有现役士兵的行政记录(n = 166万)。
我们在HADS研究期间的某个时间点确定了2937名现役独特后备役部队士兵有非致命自杀事件记录。自杀未遂(从71/100,000人年增至204/100,000人年)和自杀意念(从326/100,000人年增至425/100,000人年)的年发病率有所上升。可疑伤害的发病率总体也有所上升,但变化更大。使用分层分类规则,我们确定了每名士兵最严重行为(自杀未遂与可疑伤害与自杀意念)的首次出现情况。对于每一项与自杀或伤害相关的结果,我们发现女性、年轻、非西班牙裔白人、受教育程度较低、从未结婚以及军衔较低的应征入伍者风险增加。尽管模式相似,但这些社会人口学关联在不同结果之间存在显著差异。
研究结果提供了2004年至2009年期间后备役部队非致命自杀趋势的大致概况。它们还表明,整合多个行政数据系统丰富了对此类事件预测因素的分析。
