Sleep disturbance is common in late life. While social interaction is a basic human concern, few studies have explored the linkage between interpersonal relationships and sleep disturbance. The present study examines the reciprocal associations between weak social networks outside the household and sleep disturbance in elderly, as well as the underlying mechanisms.
We utilized data from a nationally representative longitudinal survey of community-dwelling elderly in Singapore (n = 1417; ≥ 60 years). Participants were assessed three times over 6 years (2009, 2011, 2015). Measures included strength of social networks outside the household, restless sleep (sleep disturbance), and the mediating variables of depressed mood, chronic diseases, and cognitive impairment. A cross-lagged mediation analysis was conducted.
Bootstrapping results showed that weaker social networks were related to more restless sleep via more depressed mood. Also, restless sleep was negatively associated with social networks through depressed mood. The other mediators examined were not significant.
Weak social networks and restless sleep reciprocally influence each other through depressed mood. Recognition of this interplay can inform efforts in improving elderly's sleep quality, social networks, and psychological well-being.
睡眠障碍在老年人中很常见。虽然社交互动是人类的基本需求，但很少有研究探讨人际关系与睡眠障碍之间的联系。本研究考察了老年人家庭外弱社交网络与睡眠障碍之间的相互关系，以及潜在的机制。
我们利用了新加坡一项具有全国代表性的社区居住老年人纵向调查的数据（n=1417；≥60 岁）。参与者在 6 年内接受了 3 次评估（2009 年、2011 年和 2015 年）。测量包括家庭外社交网络的强度、不安睡眠（睡眠障碍）以及中介变量抑郁情绪、慢性疾病和认知障碍。进行了交叉滞后中介分析。
Bootstrapping 结果表明，较弱的社交网络通过更多的抑郁情绪与更多的不安睡眠有关。此外，不安睡眠通过抑郁情绪与社交网络呈负相关。其他中介变量没有显著意义。
弱社交网络和不安睡眠通过抑郁情绪相互影响。认识到这种相互作用可以为改善老年人的睡眠质量、社交网络和心理健康提供信息。
