Social capital has a potential effect in protecting oral health among population. However, no study has explored the association between social capital and oral health in the Chinese context. Due to the unique culture, political, social context in China, it is important to understand their association in the Chinese context. The study aims to investigate the association between cognitive and structural dimensions of social capital with edentulism among adults aged 50 years and over in China.
The study used data from the WHO SAGE (Study on Global AGEing and Adult Health) wave 1 China component. Structural social capital was operationalized as social participation. Cognitive social capital was operationalized as perceived community trust and perceived community safety. Community-level social capital was measured by aggregating individual-level social capital into community level. Oral health was measured using a final marker of oral health status, self-reported edentulism. A 2-level multilevel logistic regression was used to evaluate the association between different dimensions of social capital and oral health.
In total, 12,856 individuals were included in the study, the overall prevalence of edentulism was 9.1% (95% CI 8.3-10.0). Multilevel logistic analysis revealed that individual-level social capital and community-level social capital are independently associated with edentulism. Individuals with low structural social capital and living in areas with low structural social capital have, respectively, 1.54 (95% CI 1.18-2.01) and 2.14 (95% CI 1.47-3.12) times higher odds for edentulism, after adjustment for potential confounders (age, sex, marital status, residence locality, wealth, education level, chronic conditions) and a potential mediator(smoking).
Living in a community with lower structural social capital and individual with low structural social capital is associated with higher risk for edentulism among adults aged 50 years and over in China.
社会资本在保护人群口腔健康方面具有潜在影响。然而，在中国语境下，还没有研究探索社会资本与口腔健康之间的关系。由于中国独特的文化、政治和社会背景，了解它们之间的关系非常重要。本研究旨在调查中国 50 岁及以上成年人社会资本的认知和结构维度与失牙状况之间的关系。
本研究使用了世界卫生组织 SAGE（全球老龄化和成人健康研究）中国第一波的数据。结构社会资本被操作化为社会参与。认知社会资本被操作化为感知社区信任和感知社区安全。社区层面的社会资本通过将个体层面的社会资本汇总到社区层面来衡量。口腔健康使用口腔健康状况的最终指标来衡量，即自我报告的失牙情况。采用 2 级多水平逻辑回归评估不同维度的社会资本与口腔健康之间的关系。
共有 12856 人参与了这项研究，失牙率为 9.1%（95%置信区间 8.3-10.0）。多水平逻辑分析显示，个体层面和社区层面的社会资本都与失牙状况独立相关。社会资本低的个体和生活在社会资本低的社区的个体，失牙的可能性分别高出 1.54 倍（95%置信区间 1.18-2.01）和 2.14 倍（95%置信区间 1.47-3.12），调整了潜在混杂因素（年龄、性别、婚姻状况、居住地、财富、教育水平、慢性疾病）和潜在中介因素（吸烟）后。
生活在社会资本较低的社区和个体社会资本较低的社区的成年人，失牙的风险更高。
