研究目的：研究在控制了一系列人口统计学、健康和生活方式变量后，与子女、亲戚、朋友和知己的社交网络是否能预测澳大利亚老年人10年以上的生存率。（澳大利亚老龄化纵向研究）地点：南澳的阿德莱德。参与者：1477名70岁或以上的老人居住在社区和住宿照顾设施。主要结果：在控制了一系列人口统计学、健康和生活方式变量后，在10年的随访期内，与朋友的更广泛的网络对死亡率有保护作用。朋友网络最高三分位数的参与者与最低三分位数的参与者相比，风险比为0.78（95%CI 0.65至0.92）。有知己的更大网络的影响较小（风险比= 0.84; 95%CI = 0.71至0.98）。社交网络与儿童和亲属的影响是不显着的生存在接下来的decade.Conclusions：生存时间可能会提高强大的社交网络。在老年澳大利亚人中，这些可能对延长生存期很重要。
Study objectives: To examine if social networks with children, relatives, friends, and confidants predict survival in older Australians over 10 years after controlling for a range of demographic, health, and lifestyle variables.Design: Prospective longitudinal cohort study ( the Australian longitudinal study of aging)Setting: Adelaide, South Australia.Participants: 1477 persons aged 70 years or more living in the community and residential care facilities.Main results: After controlling for a range of demographic, health, and lifestyle variables, greater networks with friends were protective against mortality in the 10 year follow up period. The hazard ratio for participants in the highest tertile of friends networks compared with participants in the lowest group was 0.78 ( 95% CI 0.65 to 0.92). A smaller effect of greater networks with confidants ( hazard ratio = 0.84; 95% CI = 0.71 to 0.98) was seen. The effects of social networks with children and relatives were not significant with respect to survival over the following decade.Conclusions: Survival time may be enhanced by strong social networks. Among older Australians, these may be important in lengthening survival.
