ABSTRACT

American Indian and Alaska Native (AI/AN) Veterans are at elevated risk for suicide, but currently, no population-based research exists on precursors, including ideation, plans, or attempts. We employed two large national surveys to investigate the occurrence of suicide-related behaviors among AI/AN Veterans. Using cross-sectional data from the Behavioral Risk Factor Surveillance System (BRFSS, 2010–2012) and National Survey on Drug Use and Health (NSDUH, 2010–2015), we compared weighted frequencies of suicide ideation in AI/AN Veterans and non-Hispanic White (NHW) Veterans. Suicide ideation among AI/AN Veterans was 9.1% (95%CI = 3.6%, 21.5%) and 8.9% (95%CI = 1.9%, 15.9%) in BRFSS and NSDUH, respectively, compared to 3.5% (95%CI = 3.0%, 4.1%) and 3.7% (95%CI = 3.0%, 4.4%) for NHW Veterans. Logit analysis suggested higher odds of ideation among AI/AN Veterans in both samples (NDSUH: OR = 2.68, 95%CI = 1.14–6.31; BRFSS: OR = 2.66, 95% CI 0.96–7.38), although sample sizes were small and confidence intervals were wide. Consistent findings from two national samples suggest AI/AN Veterans have more than twice the risk of suicide ideation relative to NHW Veterans. Ongoing efforts include weighing these results together with data on suicide deaths from medical and death records to develop effective suicide prevention approaches in collaboration with AI/AN Veterans and their communities.

 抽象的

美洲印第安人和阿拉斯加原住民 (AI/AN) 退伍军人的自杀风险较高，但目前尚无针对自杀前兆（包括意念、计划或尝试）的基于人群的研究。我们进行了两项大型全国性调查来调查 AI/AN 退伍军人中自杀相关行为的发生情况。使用行为风险因素监测系统（BRFSS，2010-2012）和全国药物使用与健康调查（NSDUH，2010-2015）的横断面数据，我们比较了 AI/AN 退伍军人和非退伍军人的自杀意念加权频率。西班牙裔白人 (NHW) 退伍军人。 BRFSS 和 NSDUH 中 AI/AN 退伍军人的自杀意念分别为 9.1% (95%CI = 3.6%, 21.5%) 和 8.9% (95%CI = 1.9%, 15.9%)，相比之下，自杀意念为 3.5% (95%CI = 1.9%, 15.9%) NHW 退伍军人的比例为 3.0%、4.1%）和 3.7%（95%CI = 3.0%、4.4%）。 Logit 分析表明，尽管样本量较小，但两个样本中 AI/AN 退伍军人的构思几率较高（NDSUH：OR = 2.68，95% CI = 1.14–6.31；BRFSS：OR = 2.66，95% CI 0.96–7.38）。置信区间很宽。两个全国样本的一致结果表明，AI/AN 退伍军人的自杀意念风险是 NHW 退伍军人的两倍以上。正在进行的工作包括将这些结果与医疗和死亡记录中的自杀死亡数据结合起来，与 AI/AN 退伍军人及其社区合作制定有效的自杀预防方法。
