Sleep plays an important role in the health and well-being of middle aged and elderly people, and social capital may be one of the important factors for sleep disorders. This study aimed to understand the relationship between social capital and sleep disorders in a unique region of China -Tibet that generally has the disadvantaged economic status compared to other parts of China.
The study was based on Tibetan data from The China Multi-Ethnic Cohort (CMEC) and was conducted from May 2018 to September 2019. A total of 3194 Tibetans aged > 50 were selected from the community population by multi-stage stratified cluster sampling. Social capital was measured using two validated health-related social capital scales, family/community and society.. Sleep disorders were measured as the presence of disorders of initiating and maintaining sleep, early morning awakening, or daytime dysfunction. Logistic regression models were applied to examine the association between social capital and sleep disorders.
39.9% (1271/3194) of the participants had sleep disorders. In addition, after controlling for all potential variables, family social capital was significantly negatively associated with sleep disorders (OR = 0.95, P < 0.05), while community and society social capital was not associated with sleep disorders. Then, when we did all the sex-stratified analyses, the significant association between social capital and sleep disorders was found only in women (OR = 0.94, P < 0.05), while no association was found in males; neither males nor females showed any association with community and society social capital.
Our study would help to better understand the extent of health inequality in China, and guide future interventions, strategies and policies to promote sleep quality in low-income areas, taking into account both the role of Tibetan specific cultural traditions, lifestyles and religious beliefs in social capital and the gender differences in social capital.
睡眠对中老年人的健康和幸福起着重要作用，社会资本可能是睡眠障碍的重要影响因素之一。本研究旨在了解在中国一个独特地区——西藏，社会资本与睡眠障碍之间的关系。与中国其他地区相比，西藏的经济状况普遍较差。
本研究基于中国多民族队列（CMEC）中的藏族数据，于2018年5月至2019年9月进行。通过多阶段分层整群抽样从社区人群中选取了3194名年龄大于50岁的藏族人。使用两个经过验证的与健康相关的社会资本量表（家庭/社区和社会）来衡量社会资本。睡眠障碍通过入睡和维持睡眠障碍、早醒或白天功能障碍的存在来衡量。应用逻辑回归模型来检验社会资本与睡眠障碍之间的关联。
39.9%（1271/3194）的参与者存在睡眠障碍。此外，在控制所有潜在变量后，家庭社会资本与睡眠障碍显著负相关（OR = 0.95，P < 0.05），而社区和社会社会资本与睡眠障碍无关。然后，当我们进行所有性别分层分析时，发现社会资本与睡眠障碍之间的显著关联仅在女性中存在（OR = 0.94，P < 0.05），而在男性中未发现关联；男性和女性与社区和社会社会资本均无关联。
我们的研究将有助于更好地了解中国健康不平等的程度，并指导未来促进低收入地区睡眠质量的干预措施、策略和政策，同时考虑到藏族特定文化传统、生活方式和宗教信仰在社会资本中的作用以及社会资本中的性别差异。
