Insomnia is a common sleep disorder that negatively impacts quality of life and is frequently comorbid with depression and anxiety. Chronic insomnia affects approximately 15% of the global population, with higher prevalence among females and the elderly. While existing research suggests a bidirectional relationship between insomnia and emotional disorders, the specific impact of insomnia severity on depression, anxiety, and quality of life remains unclear. This study investigates the correlation between insomnia severity and these factors in psychiatric outpatients, hypothesizing that greater insomnia severity is associated with higher levels of depression and anxiety, as well as poorer quality of life.
To explore the correlation between insomnia severity and depression, anxiety, and quality of life in primary chronic insomnia patients.
From June to December 2023, 345 patients with primary insomnia in Chifeng city were recruited and divided into three groups based on Pittsburgh sleep quality index (PSQI) scores: Mild ( = 137), moderate ( = 162), and severe ( = 46). Demographic data were collected questionnaires. Self-rating depression scale (SDS), self-rating anxiety scale (SAS), PSQI, and short form 36 (SF-36) scores were compared, and Pearson and partial correlation analyses were performed.
The greater the degree of insomnia, the greater the symptoms of depression and anxiety ( < 0.001). The more severe the insomnia, the lower the SF-36 score (excluding body pain), and the difference between the three groups was statistically significant ( < 0.001). Pearson correlation analysis and partial correlation analysis depicted the SDS score and SAS score were apparently positively correlated with the severity of insomnia ( < 0.001). Pearson correlation analysis and partial correlation analysis depicted the SF-36 scores were apparently positively correlated with the severity of insomnia ( < 0.05).
Depression and anxiety are independent factors influencing insomnia severity in primary chronic insomnia patients. Higher depression/anxiety levels correlate with worse insomnia, impacting quality of life.
失眠是一种常见的睡眠障碍，对生活质量有负面影响，且常与抑郁和焦虑并发。慢性失眠影响着全球约15%的人口，在女性和老年人中患病率更高。虽然现有研究表明失眠与情绪障碍之间存在双向关系，但失眠严重程度对抑郁、焦虑和生活质量的具体影响仍不明确。本研究调查了精神科门诊患者中失眠严重程度与这些因素之间的相关性，假设失眠严重程度越高，抑郁和焦虑水平越高，生活质量越差。
探讨原发性慢性失眠患者失眠严重程度与抑郁、焦虑及生活质量之间的相关性。
2023年6月至12月，招募了赤峰市345例原发性失眠患者，并根据匹兹堡睡眠质量指数（PSQI）评分分为三组：轻度（=137）、中度（=162）和重度（=46）。通过问卷收集人口统计学数据。比较自评抑郁量表（SDS）、自评焦虑量表（SAS）、PSQI和简明健康状况调查量表（SF-36）评分，并进行Pearson和偏相关分析。
失眠程度越严重，抑郁和焦虑症状越明显（<0.001）。失眠越严重，SF-36评分（不包括身体疼痛）越低，三组之间的差异具有统计学意义（<0.001）。Pearson相关分析和偏相关分析表明，SDS评分和SAS评分与失眠严重程度明显正相关（<0.001）。Pearson相关分析和偏相关分析表明，SF-36评分与失眠严重程度明显正相关（<0.05）。
抑郁和焦虑是影响原发性慢性失眠患者失眠严重程度的独立因素。抑郁/焦虑水平越高，失眠越严重，对生活质量产生影响。
