目的：本研究在以人群为基础的样本中检验心理和健康相关的生活质量变量与失眠的关系。方法：数据来源于一项评估失眠症自然史的纵向流行病学研究。本结果是根据在两年期间进行的四次邮政评价中的第一次评价得出的。参与者（n=953）完成了评估睡眠、心理和人格变量以及健康相关因素的问卷调查。使用基于精神障碍诊断与统计手册第四版文本修订和国际疾病分类第10版失眠诊断标准的算法，将参与者分为三个睡眠状态亚组：(1)失眠综合征（n=147），(2)失眠症状（n=308），(3)睡眠良好（n=493）。结果：与有失眠症状和睡眠良好的个体相比，失眠综合征患者的生活质量较低，在抑郁、焦虑、神经质、外向性、唤醒易感性、压力感知和情绪导向应对等方面得分较高。与睡眠良好的人相比，有失眠症状的人也观察到同样的模式。一项有序逻辑回归分析显示，过去失眠发作的存在，较高的抑郁症状，以及在12项简短健康调查中较低的得分，活力和角色身体量表是预测亚组成员资格的最有用的变量。结论：研究结果表明，失眠与心理症状和感知压力增加、觉醒倾向增加和健康质量受损有关。目前正在进行纵向随访，以评估这些变量在失眠的发展和自然过程中的相对贡献。(c) 2007爱思唯尔公司版权所有。
Objective: This study examined the relationship of psychological and health-related quality of life variables to insomnia in a population-based sample. Methods: Data were derived from a longitudinal epidemiological study assessing the natural history of insomnia. The present results are based on the first of four postal evaluations conducted over a 2-year period. Participants (n=953) completed questionnaires assessing sleep, psychological and personality variables, and health-related factors. Participants were categorized into three sleep status subgroups using an algorithm based on Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, Text Revision and International Classification of Diseases, 10th Edition diagnostic criteria for insomnia: (1) insomnia syndrome (n=147), (2) insomnia symptoms (n=308), and (3) good sleepers (n=493). Results: Compared to individuals with insomnia symptoms and good sleepers, individuals with insomnia syndrome presented lower quality of life and higher scores on measures of depression, anxiety, neuroticism, extraversion, arousal predisposition, stress perception, and emotion-oriented coping. The same pattern was observed for individuals with insomnia symptoms in comparison with good sleepers. An ordinal logistic regression analysis showed that the presence of a past episode of insomnia, higher depressive symptoms, and lower scores on the 12-item Short Form Health Survey vitality and role physical subscales were the most useful variables to predict subgroups membership. Conclusion: The findings indicate that insomnia is associated with increased psychological symptomatology and perceived stress, higher predisposition to arousal, and more impairment of health quality. Longitudinal follow-ups are now being conducted to assess the relative contribution of those variables in the development and natural course of insomnia. (c) 2007 Elsevier Inc. All rights reserved.
