本研究探讨了老年白色女性社会网络特征与死亡率之间的年龄相关差异。受试者包括1984年居住在马里兰州东北部巴尔的摩的年龄≥ 65岁的白色妇女（n = 806）。社交网络的三个特征被测量：网络资源的可用性;与网络资源的联系;以及融入邻里。社会网络与5年死亡率的关系采用比例风险模型进行了研究，该模型调整了感知的健康状况，日常生活中的身体活动障碍，慢性疾病的数量和受教育年限。分析按年龄分层（65-74岁，≥ 75岁）。社会网络联系和邻里融合的因素与年龄≥ 75岁的女性死亡率降低相关，但在65-74岁的女性中则无关。在≥ 75岁组中，与儿童、朋友和团体组织没有接触的妇女的风险比（95%置信区间（CI））分别为3.1（1.2-7.5）、2.2（1.0-4.9）和2.8（1.2-6.5）。在附近居住≥ 10年的女性和与当地商人没有互动的女性的风险比分别为2.5（95%CI 1.3-4.8）和2.2（95%CI 1.2-3.9）。因此，年龄和网络结构的具体方面被发现影响社交网络和老年妇女死亡率之间的关联。
This study examines age-related differences in the association between social network characteristics and mortality for aged white women. Subjects include a community-dwelling sample of white women aged > or = 65 years (n = 806), who lived in northeast Baltimore, Maryland, in 1984. Three characteristics of social networks were measured: availability of network resources; contact with network resources; and integration into the neighborhood. The association of social network with 5-year mortality was examined with a proportional hazards model adjusting for perceived health status, impairment in physical activities of daily living, number of chronic conditions, and years of education. Analyses were stratified by age (65-74 years, > or = 75 years). Elements of social network contact and neighborhood integration were associated with reduced mortality among women aged > or = 75 years, but not among women aged 65-74 years. In the > or = 75 years group, women who had no contact with children, friends, and group organizations showed hazard ratios (95% confidence intervals (CI)) of 3.1 (1.2-7.5), 2.2 (1.0-4.9), and 2.8 (1.2-6.5), respectively. Women who had lived < or = 10 years in the neighborhood and women who had no interaction with local merchants showed hazard ratios of 2.5 (95% CI 1.3-4.8) and 2.2 (95% CI 1.2-3.9), respectively. Thus, both age and specific aspects of network structure were found to influence the association between social networks and mortality in elderly women.
