本研究旨在确定失眠的哪些症状成分或状况与失眠的主观感觉、低健康相关生活质量（HRQOL）或抑郁有关。方法对7027名日本成年人的网络问卷调查数据进行分析，分析人口学变量与匹兹堡睡眠质量指数（PSQI）中每个睡眠困难症状项与主观失眠症的存在/不存在以及流行病学研究中心抑郁量表（CES-D）和短表8 （SF-8）得分之间的关系。结果主观性失眠症患病率为12.2%（860例）。判别函数分析显示，PSQI和CES-D的睡眠质量、睡眠潜伏期和睡眠药物使用项目得分在识别失眠症主观感觉的积极性方面具有较高的判别函数系数。在主观失眠症的调查对象中，较低的SF-8身体成分总结得分与较高的年龄、抑郁状态、睡眠困难和白天功能障碍的PSQI项目相关，而较低的SF-8精神成分总结得分与抑郁状态、PSQI睡眠潜伏期、睡眠药物使用和白天功能障碍相关。抑郁状态与睡眠潜伏期、睡眠药物使用和日间功能障碍显著相关。结论在失眠症状组成中，睡眠质量紊乱和睡眠性失眠可能与主观感觉障碍有特异性关联。抑郁状态的存在不仅与主观失眠有关，而且与身心生活质量也有显著关系。我们的研究结果还表明，由PSQI测量的睡眠困难的不同组成部分可能与精神和身体生活质量以及抑郁状态有关。
BackgroundThis study was conducted to determine what symptom components or conditions of insomnia are related to subjective feelings of insomnia, low health-related quality of life (HRQOL), or depression.Method Data from 7,027 Japanese adults obtained using an Internet-based questionnaire survey was analyzed to examine associations between demographic variables and each sleep difficulty symptom item on the Pittsburgh Sleep Quality Index (PSQI) with the presence/absence of subjective insomnia and scores on the Short Form-8 (SF-8) and Center for Epidemiologic Studies Depression Scale (CES-D).Results Prevalence of subjective insomnia was 12.2 % (n = 860). Discriminant function analysis revealed that item scores for sleep quality, sleep latency, and sleep medication use on the PSQI and CES-D showed relatively high discriminant function coefficients for identifying positivity for the subjective feeling of insomnia. Among respondents with subjective insomnia, a low SF-8 physical component summary score was associated with higher age, depressive state, and PSQI items for sleep difficulty and daytime dysfunction, whereas a low SF-8 mental component summary score was associated with depressive state, PSQI sleep latency, sleeping medication use, and daytime dysfunction. Depressive state was significantly associated with sleep latency, sleeping medication use, and daytime dysfunction.Conclusion Among insomnia symptom components, disturbed sleep quality and sleep onset insomnia may be specifically associated with subjective feelings of the disorder. The existence of a depressive state could be significantly associated with not only subjective insomnia but also mental and physical QOL. Our results also suggest that different components of sleep difficulty, as measured by the PSQI, might be associated with mental and physical QOL and depressive status.
