目的：这种病例对照心理尸检研究的目的是探讨睡眠障碍和自杀之间的关系，日本，以及确定的重要性和可用性筛选睡眠障碍在suiceprotection.Methods：一个半结构化的采访进行了密切的家庭成员的49名成年自杀完成者和145名性别，年龄，和住宅的相似性匹配的生活对照。调查包括人口统计学、睡眠障碍和精神障碍等部分。结果：自杀组睡眠障碍发生率（75.5%）显著高于对照组（11.0%）（OR =21.6，p < 0.001）。在调整精神障碍后，这种关联仍然显著（OR = 12.7，p < 0.001）。与睡眠障碍和精神障碍相关的自杀人群归因危险度分别为56.4%和35.3%。在日本人口中，由于患病率较高，睡眠障碍在自杀病例中所占比例高于精神障碍，因此可以将其视为日本预防自杀的一个重要目标。(C)2014年爱思唯尔B。V.保留所有权利。
Objective: This case-control psychological autopsy study aimed to explore a relationship between sleep disturbances and suicide among Japanese, as well as determine the importance and usability of screening for sleep disturbances in suicide prevention.Methods: A semi-structured interview was conducted with the close family members of 49 adult suicide completers and 145 gender-, age-, and residential municipality-matched living controls. The survey included sections on demographics, sleep disturbances, and mental disorders. Conditional logistic regression analyses were performed to compare sleep disturbance prevalence between the two groups.Results: A significantly higher prevalence of sleep disturbances was found among the suicide group (75.5%) compared to the controls (11.0%) (odds ratio [OR]=21.6, p < 0.001). The association remained significant after adjusting for mental disorders (OR = 12.7, p < 0.001). The population attributable risk percent of suicide associated with sleep disturbances and mental disorders was estimated to be 56.4% and 35.3%, respectively.Conclusions: The study confirmed that sleep disturbances are an important risk factor of suicide, independent of mental disorders. Sleep disturbances accounted for a greater proportion of suicide cases than did mental disorders in the Japanese population given the higher prevalence, and could thus be considered an important target in suicide prevention in Japan.
