Considerable research indicates that sleep disturbances and insomnia are more common and severe among individuals following a traumatic brain injury (TBI). It remains unclear, however, how the experience of multiple TBIs affect sleep disturbances and insomnia. The current study investigated the incidence and severity of insomnia and sleep complaints among active-duty military personnel who have sustained multiple TBIs.
Upon intake at a military TBI clinic located in Iraq, 150 male military patients completed standardized self-report measures and clinical interviews.
Patients were categorized into three groups according to history of TBI: zero TBIs (n = 18), single TBI (n = 54), multiple TBIs (n = 78). Rates of clinical insomnia significantly increased across TBI groups (P < 0.001):- 5.6% for no TBIs, 20.4% for single TBI, and 50.0% for multiple TBIs. Insomnia severity significantly increased across TBI groups even when controlling for depression, posttraumatic stress disorder, and concussion symptom severity (B = 1.134, standard error = 0.577, P = 0.049).
Multiple TBIs are associated with increased risk for and severity of sleep disturbance among male military personnel.
大量研究表明，创伤性脑损伤（TBI）后，个体的睡眠障碍和失眠更为常见且严重。然而，多次 TBI 对睡眠障碍和失眠的影响尚不清楚。本研究调查了在伊拉克的一个军事 TBI 诊所接受治疗的现役军人中，多次 TBI 对失眠和睡眠问题的发生率和严重程度的影响。
在位于伊拉克的军事 TBI 诊所接受治疗时，150 名男性军事患者完成了标准化的自我报告量表和临床访谈。
根据 TBI 病史，患者被分为三组：无 TBI（n = 18）、单次 TBI（n = 54）、多次 TBI（n = 78）。临床失眠的发生率随着 TBI 次数的增加而显著增加（P < 0.001）：无 TBI 的发生率为 5.6%，单次 TBI 的发生率为 20.4%，多次 TBI 的发生率为 50.0%。即使控制抑郁、创伤后应激障碍和脑震荡症状严重程度，失眠严重程度仍随着 TBI 次数的增加而显著增加（B = 1.134，标准误差 = 0.577，P = 0.049）。
多次 TBI 与男性军事人员睡眠障碍风险增加和失眠严重程度增加相关。
