研究目的：越来越多的研究表明，睡眠障碍可能与自杀行为特别相关。然而，目前还不清楚这种联系是否在很大程度上可以用抑郁症状来解释。本研究调查自杀，抑郁症，睡眠投诉之间的关系，在临床outpatient setting.Design和设置：入院后，176名门诊患者完成了睡眠障碍，自杀症状，抑郁症的措施。几个睡眠障碍进行了评估方面的自杀ideation.Measurements和结果：回归分析显示，失眠和噩梦的症状与抑郁症状和自杀，睡眠相关的呼吸症状与抑郁症状，但没有表现出与自杀ideation。在控制了抑郁症状后，只有噩梦与自杀意念有关。这种关系表现为非显著趋势（P = .06）。与男性相比，女性的夜惊与自杀倾向尤其相关。事后分析显示，在控制了性别和抑郁症状后，噩梦症状与自杀倾向显著相关（P = .04）。结论：虽然失眠和噩梦与抑郁和自杀症状显著相关，但在控制了其他变量（如抑郁和性别）后，只有噩梦仍与自杀倾向相关。与男子相比，妇女中的这种关联性略强。
Study Objectives: A growing body of research indicates that sleep disturbances may be specifically linked to suicidal behaviors. It remains unclear, however, whether this link is largely explained by depressive symptoms. The present study investigated the relationship between suicidality, depression, and sleep complaints in a clinical outpatient setting.Design and Setting: Upon admission, 176 outpatients completed measures on sleep disturbances, suicidal symptoms, and depression. Several sleep disturbances were evaluated with regard to suicidal ideation, including insomnia, nightmares, and sleep-related breathing symptoms.Measurements and Results: Regression analyses revealed that insomnia and nightmare symptoms were associated with both depressive symptoms and suicidality, Sleep-related breathing symptoms were associated with depressive symptoms, but did not show an association with suicidal ideation. After controlling for depressive symptoms, only nightmares demonstrated an association with suicidal ideation. This relationship emerged as a nonsignificant trend (P = .06). Nightmares were particularly associated with suicidality among women compared with men. Posthoc analyses revealed that, after controlling for sex and depressive symptoms, nightmare symptoms were significantly associated with suicidality (P = .04).Conclusions: Although insomnia and nightmares were significantly associated with depressive and suicidal symptoms, after controlling for additional variables, such as depression and sex, only nightmares remained associated with suicidality. This association was slightly stronger among women compared with men.
