背景资料：需要更多的知识，社会资本的各个方面如何与死亡率独立或介导的其他因素。在这项队列研究中，个人水平的社会资本被评估为全因死亡率的可能预测因子。方法：对2000-01年进行的全国代表性健康2000调查的参与者进行了9年死亡率随访。调查包括个人访谈、自填问卷和健康检查。对不同项目的答复率在80%至88%之间。由于项目无应答，使用多重插补替换缺失值。参与者（N = 6377）在基线时年龄为30-79岁。在随访期间，245名女性和340名男性死亡。考克斯回归模型被用来评估社会资本和死亡率之间的关系。我们分析了社会资本的三个维度：社会支持、社会参与和信任。根据若干社会人口因素、健康行为、健康和生物风险因素调整了它们与死亡风险的关联。结果：即使调整了其他因素，不积极的社会参与也与较高的死亡风险相关。男性中的相关性[风险比（HR）= 1.56]比女性（HR = 1.42）更强。社会资本的其他两个维度与死亡率相关时，只有年龄调整，但这种关联消失时，社会参与的解释模型。结论：积极的社会参与可以防止过早死亡。这种关联部分是通过健康行为介导的，在较小程度上也是通过健康介导的。
Background: More knowledge is needed about how various dimensions of social capital associate with mortality either independently or mediated by other factors. In this cohort study, individual-level social capital was assessed as a possible predictor of all-cause mortality. Methods: A 9-year mortality follow-up was conducted for participants of a nationally representative Health 2000 Survey carried out in 2000-01. The survey included a personal interview, self-administered questionnaires and a health examination. Response rates to different items varied between 80 and 88%. Due to the item non-response, missing values were replaced by using multiple imputation. Participants (N = 6377) were 30-79 years old at the baseline. During the follow-up period, 245 women and 340 men died. Cox regression models were used to assess the association between social capital and mortality. We analysed three dimensions of social capital: social support, social participation and trust. Their association with the risk of death was adjusted for several socio-demographic factors, health behaviours, health and biological risk factors. Results: Unactive social participation was associated with higher mortality risk even when adjusting for the other factors. The association was stronger among men [hazard ratio (HR) = 1.56] than women (HR = 1.42). The other two dimensions of social capital were associated with mortality when only age was adjusted for, but this association disappeared when social participation was included in the explanatory model. Conclusions: Active social participation protects against early death. This association is partly mediated through health behaviour and to a minor extent also through health.
