STUDY OBJECTIVES Post-9/11 veterans are particularly vulnerable to insomnia disorder. Having accurate prevalence rates of insomnia disorder in this relatively young, diverse population, is vital to determine the resources needed to identify and treat insomnia disorder. However, there are no accurate prevalence rates for insomnia disorder in post-9/11 veterans enrolling in the VA Healthcare System (VHA). We present accurate prevalence of insomnia disorder, and correlates, in a large sample of post-9/11 veterans enrolling in a VHA. METHODS This was an observational study of 5552 post-9/11 veterans newly enrolling for health care in a VHA. Data were collected using VA eScreening. Insomnia diagnosis was determined using a clinical cut-off score of >= 11 on the Insomnia Severity Index (ISI). Measures also included sociodemographic, service history, posttraumatic stress disorder (PTSD), depression, suicidal ideation, alcohol misuse, military sexual trauma (MST), traumatic brain injury (TBI), and pain intensity. RESULTS 57.2% of the sample population had insomnia disorder. Our sample was nationally representative for age, sex, ethnicity, branch of the military, and race. The sample also was at high-risk for a host of clinical disorders, including PTSD, TBI, and pain; all of which showed higher rates of insomnia disorder (93.3%, 77.7%, and 69.6% respectively). CONCLUSIONS The findings suggest alarmingly high rates of insomnia disorder in this population. Examining and treating insomnia disorder, especially in the context of co-occurring disorders (e.g., PTSD) will be a necessity in the future.

9/11 后参加 VA 医疗保健的退伍军人中失眠症的患病率和相关性


研究目标 9/11 后退伍军人特别容易患失眠症。在这个相对年轻、多样化的人群中掌握失眠症的准确患病率对于确定识别和治疗失眠症所需的资源至关重要。然而，在加入 VA 医疗系统 (VHA) 的 9/11 事件后退伍军人中，尚无准确的失眠症患病率。我们在 9/11 后参加 VHA 的退伍军人的大样本中准确展示了失眠症的患病率及其相关性。方法 这是一项针对 5552 名 9/11 后新参加 VHA 医疗保健的退伍军人的观察性研究。使用 VA eScreening 收集数据。失眠诊断是通过失眠严重指数 (ISI) 的临床截止分数 >= 11 来确定的。衡量标准还包括社会人口统计、服役史、创伤后应激障碍（PTSD）、抑郁、自杀意念、酗酒、军事性创伤（MST）、创伤性脑损伤（TBI）和疼痛强度。结果 57.2%的样本人群患有失眠症。我们的样本在年龄、性别、民族、军种和种族方面具有全国代表性。该样本还存在许多临床疾病的高风险，包括创伤后应激障碍 (PTSD)、创伤性脑损伤 (TBI) 和疼痛；所有这些人的失眠症发生率均较高（分别为 93.3%、77.7% 和 69.6%）。结论 研究结果表明，这一人群的失眠症发病率高得惊人。检查和治疗失眠症，特别是在同时发生的疾病（例如创伤后应激障碍（PTSD））的情况下，在未来将是必要的。
