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.
研究目的
在控制一系列人口统计学、健康和生活方式变量后，研究与子女、亲属、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。
设计
前瞻性纵向队列研究（澳大利亚老龄化纵向研究）
地点
南澳大利亚州阿德莱德
参与者
1477名年龄在70岁及以上、居住在社区和养老机构的人
主要结果
在控制一系列人口统计学、健康和生活方式变量后，在10年随访期内，与朋友有更多社交网络对死亡率有保护作用。朋友网络处于最高三分位数的参与者与最低组参与者相比，风险比为0.78（95%置信区间0.65至0.92）。与知己有更多社交网络的影响较小（风险比=0.84；95%置信区间=0.71至0.98）。在接下来的十年中，与子女和亲属的社交网络对生存率的影响不显著。
结论
强大的社交网络可能会延长生存时间。在澳大利亚老年人中，这些社交网络可能对延长生存期很重要。
