OBJECTIVE
Existing research has yet to adequately examine the correlation between sleep time, body pain, and depressive symptoms. This study seeks to elucidate the interconnections between these three elements.
METHODS
The study used 2020 CHARLS data for analysis. To assess the intricate association among sleep time, body pain, and depressive symptoms, the study employed Spearman correlation analysis, multiple logistic regression, restricted cubic splines, and mediation effect analysis based on bootstrap testing.
RESULTS
Risk factors for depressive symptoms in middle-aged and elderly Chinese include physical pain and reduced sleep duration. Results from the RCS suggest that the lowest risk of depressive symptoms occurs when the sleep time for the middle-aged and elderly population is approximately 7.5 hours. Body pain accounts for a 19.05% mediating effect between sleep time and depressive symptoms, and even after controlling confounding factors, there remains a 7.5% mediating effect.
CONCLUSION
The research findings indicate that there is a significant correlation among sleep time, body pain, and depressive symptoms. Insufficient sleep time and body pain can lead to depressive symptoms. Body pain plays a partial mediating role between sleep time and depressive symptoms.
目的
现有研究尚未充分考察睡眠时间、身体疼痛与抑郁症状之间的相关性。本研究旨在阐明这三个因素之间的内在联系。
方法
本研究使用2020年中国健康与养老追踪调查（CHARLS）数据进行分析。为评估睡眠时间、身体疼痛与抑郁症状之间的复杂关联，本研究采用了Spearman相关性分析、多元逻辑回归、受限立方样条以及基于自抽样检验的中介效应分析。
结果
中国中老年人群抑郁症状的风险因素包括身体疼痛和睡眠时间缩短。受限立方样条结果表明，中老年人群睡眠时间约为7.5小时时，抑郁症状风险最低。身体疼痛在睡眠时间和抑郁症状之间的中介效应为19.05%，即使在控制混杂因素后，仍存在7.5%的中介效应。
结论
研究结果表明，睡眠时间、身体疼痛与抑郁症状之间存在显著相关性。睡眠时间不足和身体疼痛会导致抑郁症状。身体疼痛在睡眠时间和抑郁症状之间起部分中介作用。
