一个人的社会关系网的大小与健康和寿命有关，但目前还不清楚是强社会关系的数量还是弱社会关系的数量对健康最有影响。我们在芬兰公共部门研究（n = 7，617）和健康与社会支持研究（n = 20，816）中检查了社会网络特征作为死亡率预测因素。1998年在基线调查了社会网络特征。有关死亡率的信息来自芬兰国家死亡登记处。在平均16年的随访期内，参与者的社交网络较小（= 21名成员）（调整后的风险比（HR）= 1.23，95%置信区间（CI）：1.04，1.46）。死亡风险增加的参与者中，既有少数强关系（
The size of a person's social network is linked to health and longevity, but it is unclear whether the number of strong social ties or the number of weak social ties is most influential for health. We examined social network characteristics as predictors of mortality in the Finnish Public Sector Study (n = 7,617) and the Health and Social Support Study (n = 20,816). Social network characteristics were surveyed at baseline in 1998. Information about mortality was obtained from the Finnish National Death Registry. During a mean follow-up period of 16 years, participants with a small social network (= 21 members) (adjusted hazard ratio (HR) = 1.23, 95% confidence interval (CI): 1.04, 1.46). Mortality risk was increased among participants with both a small number of strong ties (
