Whereas the majority of previous research on social capital and health has been on residential neighborhoods and communities, the evidence remains sparse on workplace social capital. To address this gap in the literature, we examined the association between workplace social capital and health status among Chinese employees in a large, multi-level, cross-sectional study.
By employing a two-stage stratified random sampling procedure, 2,796 employees were identified from 35 workplaces in Shanghai during March to November 2012. Workplace social capital was assessed using a validated and psychometrically tested eight-item measure, and the Chinese language version of the WHO-Five Well-Being Index (WHO-5) was used to assess mental health. Control variables included sex, age, marital status, education level, occupation status, smoking status, physical activity, and job stress. Multilevel logistic regression analysis was conducted to explore whether individual- and workplace-level social capital was associated with mental health status.
In total, 34.9% of workers reported poor mental health (WHO-5<13). After controlling for individual-level socio-demographic and lifestyle variables, compared to workers with the highest quartile of personal social capital, workers with the third, second, and lowest quartiles exhibited 1.39 to 3.54 times greater odds of poor mental health, 1.39 (95% CI: 1.10-1.75), 1.85 (95% CI: 1.38-2.46) and 3.54 (95% CI: 2.73-4.59), respectively. Corresponding odds ratios for workplace-level social capital were 0.95 (95% CI: 0.61-1.49), 1.14 (95% CI: 0.72-1.81) and 1.63 (95% CI: 1.05-2.53) for the third, second, and lowest quartiles, respectively.
Higher workplace social capital is associated with lower odds of poor mental health among Chinese employees. Promoting social capital at the workplace may contribute to enhancing employees' mental health in China.
尽管先前关于社会资本与健康的大多数研究都集中在居住社区，但关于工作场所社会资本的证据仍然很少。为了弥补这一文献空白，我们在一项大型、多层次、横断面研究中调查了中国员工工作场所社会资本与健康状况之间的关联。
2012 年 3 月至 11 月期间，采用两阶段分层随机抽样程序，从上海的 35 个工作场所中确定了 2796 名员工。使用经过验证和心理测试的八项措施评估工作场所社会资本，使用世界卫生组织五维健康指数（WHO-5）的中文版本评估心理健康。控制变量包括性别、年龄、婚姻状况、教育程度、职业状况、吸烟状况、身体活动和工作压力。采用多水平逻辑回归分析方法，探讨个体和工作场所社会资本与心理健康状况之间的关系。
共有 34.9%的工人报告心理健康状况不佳（WHO-5<13）。在控制了个体社会人口统计学和生活方式变量后，与个人社会资本最高四分位数的工人相比，个人社会资本第三、第二和最低四分位数的工人心理健康状况不佳的几率分别高出 1.39 倍至 3.54 倍，1.39（95%CI：1.10-1.75）、1.85（95%CI：1.38-2.46）和 3.54（95%CI：2.73-4.59）。相应的工作场所社会资本比值比分别为 0.95（95%CI：0.61-1.49）、1.14（95%CI：0.72-1.81）和 1.63（95%CI：1.05-2.53），用于第三、第二和最低四分位数。
较高的工作场所社会资本与中国员工心理健康状况不佳的几率较低有关。在中国，促进工作场所的社会资本可能有助于提高员工的心理健康水平。
