生活质量与睡眠质量的关系:感知压力和睡眠焦虑的链式中介作用

The Relationship Between Quality of Life and Quality of Sleep:The Chain Mediation Effects of Perceived Stress and Sleep Anxiety

睡眠问题是全球范围内的重大公共卫生问题。国内外很多研究已经充分证明了睡眠质量与生活质量的关系,但缺乏两者反向关系的相关研究;此外,关于生活质量对睡眠质量的作用机制也鲜有研究涉及。综合考虑以上因素,探究中国普通成年人群的生活质量与主观睡眠质量的关系,以及感知压力和睡眠焦虑在两者关系中的作用机制。结果表明:中国普通成年人群的生活质量与主观睡眠质量呈正相关;感知压力在生活质量与主观睡眠质量的关系中具有独立的中介作用;睡眠焦虑在生活质量与主观睡眠质量的关系中具有独立的中介作用;感知压力和睡眠焦虑在睡眠质量与主观睡眠质量的关系中具有链式中介作用。结果揭示了中国普通成年人群的生活质量和主观睡眠质量的关系,并验证了生活质量、主观睡眠质量、感知压力以及睡眠焦虑这四者之间的关系和机制;提示人们在日常生活中形成压力感知的钝感力,或减少对自身睡眠的负面关注,均有助于强化良好的生活质量对睡眠质量的有益影响。

Sleep problems are a major global public health issue.Numerous studies both domestically and internationally have extensively demonstrated the relationship between sleep quality and quality of life,but there is a lack of research on the reverse relationship between the two.Additionally,the mechanisms by which quality of life affects sleep quality are rarely studied.Considering these factors,this study aims to explore the relationship between quality of life and subjective sleep quality among the general adult population in China,and to examine the mediating roles of perceived stress and sleep anxiety in this relationship.The results indicate that:Quality of life is positively correlated with subjective sleep quality among the general adult population in China;perceived stress has an independent mediating effect on the relationship between quality of life and subjective sleep quality;sleep anxiety also independently mediates the relationship between quality of life and subjective sleep quality;perceived stress and sleep anxiety jointly mediate the relationship between quality of life and subjective sleep quality in a chain mediation model.These findings reveal the relationship between quality of life and subjective sleep quality among the general adult population in China and validate the mechanism involving quality of life,subjective sleep quality,perceived stress,and sleep anxiety.The results suggest that developing an acute awareness of perceived stress or reducing negative attention to one’s sleep in daily life can enhance the beneficial impact of good quality of life on sleep quality.
