The aim of the inquiry was to examine the social network-mortality association within a wider multivariate context that accounts for the effects of background framing forces and psychobiological pathways. The inquiry was based upon the Berkman et al. (2000) conceptual model of the determinants of health. Its main purpose was to identify the salient network correlates of 7-year all cause mortality among Jewish men and women, aged 70 and over, in Israel ( = 1,811). The investigation utilized baseline data from a national household survey of older adults from 1997 that was linked to records from the National Death Registry, updated through 2004. At the time of the study, 38% of the sample had died. Multivariate Cox hazard regressions identified two main network-related components as predictors of survival: contact with friends, a social network interaction variable, and attendance at a synagogue, a social engagement variable. Friendship ties are seen to uniquely reduce mortality risk because they are based on choice in nature, and reflect a sense of personal control. Synagogue attendance is seen to promote survival mainly through its function as a source of communal attachment and, perhaps, as a reflection of spirituality as well. Other possibly network-related correlates of mortality were also noted in the current analysis-the receipt of instrumental support and the state of childlessness.
该调查的目的是在一个更广泛的多变量背景下研究社交网络与死亡率之间的关联，该背景考虑了背景框架力量和心理生物学途径的影响。该调查基于伯克曼等人（2000年）的健康决定因素概念模型。其主要目的是确定以色列70岁及以上犹太男性和女性（n = 1811）中7年全因死亡率的显著网络相关因素。该调查利用了1997年全国老年人家庭调查的基线数据，这些数据与国家死亡登记处的记录相关联，并更新至2004年。在研究时，38%的样本已经死亡。多变量Cox风险回归确定了两个主要的与网络相关的因素作为生存的预测因素：与朋友的联系，一个社交网络互动变量，以及参加犹太教堂活动，一个社会参与变量。友谊关系被认为能独特地降低死亡风险，因为它们本质上基于选择，并反映了个人控制感。参加犹太教堂活动被认为主要通过其作为社区依恋来源的功能，也许还作为精神性的一种反映来促进生存。在当前分析中还注意到了其他可能与网络相关的死亡相关因素——获得工具性支持和无子女状况。
