The aim of the present study was to examine the association of insomnia symptoms with demographic and physical and mental conditions in a large population-based study.
Cross-sectional data on insomnia and comorbid conditions were gathered from 47,700 individuals aged 20-89 in Norway. Comorbid conditions included anxiety and depression and the following physical conditions: asthma, allergy, cancer, hypertension, diabetes, migraine, headache, osteoporosis, fibromyalgia rheumatoid arthritis, arthrosis, Bechterew's disease, musculoskeletal disorders, and obesity (body mass index >30).
Insomnia symptoms were found in 13.5% of the population and were more prevalent among women, older adults, and in individuals with less education. Reporting insomnia symptoms significantly increased the associations with a range of conditions, especially mental conditions, pain conditions with uncertain etiology and, to a lesser extent, chronic pain conditions. These findings remained significant also when adjusting for a range of potential confounders, whereas the association between insomnia and somatic conditions was largely reduced to a nonsignificant level in the fully adjusted analyses.
This study demonstrates that insomnia symptoms are associated with a range of different conditions. The findings suggest that the independent contribution of insomnia is strongest on conditions characterized by some level of psychological or psychosomatic properties.
本研究旨在通过一项基于大规模人群的研究，探讨失眠症状与人口统计学因素以及身体和精神状况之间的关联。
收集了挪威47700名年龄在20至89岁之间的个体关于失眠及共病状况的横断面数据。共病状况包括焦虑和抑郁以及以下身体状况：哮喘、过敏、癌症、高血压、糖尿病、偏头痛、头痛、骨质疏松症、纤维肌痛、类风湿性关节炎、关节病、贝赫切特病、肌肉骨骼疾病和肥胖（体重指数>30）。
13.5%的人群存在失眠症状，女性、老年人以及受教育程度较低者中更为普遍。报告失眠症状显著增加了与一系列状况的关联，尤其是精神状况、病因不明的疼痛状况，以及在较小程度上的慢性疼痛状况。在对一系列潜在混杂因素进行调整后，这些发现仍然显著，而在完全调整分析中，失眠与躯体状况之间的关联在很大程度上降至不显著水平。
本研究表明失眠症状与一系列不同状况相关。研究结果表明，失眠对具有一定心理或心身特征的状况的独立影响最为显著。
