to examine the causal relationship between sleep quality and life satisfaction and explore the mediating role of health status on the relationship between sleep quality and life satisfaction.
A total of 1856 older Chinese people participating in 2011, 2014, and 2018 waves of the Chinese Longitudinal Healthy Longevity Survey (CLHLS) were included. A cross-lagged panel analysis (CLPA) combined with mediator analysis was utilized.
The average sleep quality levels for the years 2011, 2014, and 2018 were 3.70, 3.63, and 3.47 out of 5, respectively. The corresponding average levels of health status were 3.47, 3.44, and 3.39 out of 5, and the average levels of life satisfaction were 3.75, 3.86, and 3.87 out of 5, respectively. In addition, sleep quality at prior assessment points was significantly associated with life quality at subsequent assessments, and vice versa. Also, health status partially mediated this prospective reciprocal relationship.
There is a nonlinear decreased trend in sleep quality and health status, while there exists a nonlinear increased trend in life satisfaction for older adults from 2011 to 2018. Reciprocal positive effects between sleep quality and life satisfaction in older adults exist and are mediated by health status.
探讨睡眠质量与生活满意度之间的因果关系，并探究健康状况在睡眠质量与生活满意度关系中的中介作用。
纳入了总共1856名参与2011年、2014年和2018年中国健康与养老追踪调查（CLHLS）的中国老年人。采用了交叉滞后面板分析（CLPA）结合中介分析的方法。
2011年、2014年和2018年的平均睡眠质量水平分别为5分制中的3.70、3.63和3.47。相应的健康状况平均水平分别为5分制中的3.47、3.44和3.39，生活满意度平均水平分别为5分制中的3.75、3.86和3.87。此外，先前评估点的睡眠质量与后续评估中的生活质量显著相关，反之亦然。而且，健康状况部分介导了这种前瞻性的相互关系。
2011年至2018年，老年人的睡眠质量和健康状况呈非线性下降趋势，而生活满意度呈非线性上升趋势。老年人的睡眠质量与生活满意度之间存在相互正向影响，且由健康状况介导。
