The impact of social relationships on the maintenance of independence over periods of 12-18 months in a group of 306 octogenarians is assessed in this study. The study is based on the results of the Swilsoo (Swiss Interdisciplinary Longitudinal Study on the Oldest Old). Participants (80-84 years old at baseline) were interviewed five times between 1994 and 1999. Independence was defined as the capacity to perform without assistance eight activities of daily living. We distinguished in our analyses kinship and friendship networks and evaluated social relationships with the help of a series of variables serving as indicators of network composition and contact frequency. Logistic regression models were used to identify the short-term effects of social relationships on independence, after controlling for sociodemographic and health-related variables; independence at a given wave of interviews was interpreted in the light of social factors measured at the previous wave. Our analyses indicate that the existence of a close friend has a significant impact on the maintenance of independence (OR=1.58, p<0.05), which is not the case with the other variables concerning network composition. Kinship contacts were also observed to have a positive impact on independence (OR=1.12, p<0.01).
本研究评估了社会关系对306名八旬老人在12至18个月期间维持独立生活能力的影响。该研究基于Swilsoo（瑞士关于最年长者的跨学科纵向研究）的结果。参与者（基线年龄为80 - 84岁）在1994年至1999年期间接受了五次访谈。独立生活能力被定义为无需他人协助即可完成八项日常生活活动的能力。在分析中，我们区分了亲属关系网络和朋友关系网络，并借助一系列作为网络构成和联系频率指标的变量来评估社会关系。在控制了社会人口统计学和健康相关变量后，使用逻辑回归模型来确定社会关系对独立生活能力的短期影响；根据上一轮访谈中测量的社会因素来解释某一轮访谈时的独立生活能力情况。我们的分析表明，有亲密朋友对维持独立生活能力有显著影响（OR = 1.58，p < 0.05），而其他与网络构成有关的变量则不然。亲属联系也被观察到对独立生活能力有积极影响（OR = 1.12，p < 0.01）。
