为了确定是否更频繁地参与更大的社会网络，以及更多的情感支持可以防止认知和功能随着年龄的增长而下降。我们研究了社会网络对认知和日常生活工具活动（IADLs）的影响，平均间隔为10.9年。数据来自巴尔的摩对流行病学集水区（ECA）研究的随访，该研究是在巴尔的摩东部以社区为基础的成年人样本，874名参与者完成了第三和第四研究阶段（1993-1996和2003-2004）的认知测试，包括迷你精神状态检查（MMSE）和延迟单词回忆任务。两波的功能状态均在劳顿-布罗迪IADL量表上自我报告。在第三次研究中评估的社会网络特征包括网络规模、联系频率和情感支持。在波3的横断面分析中，更大的网络与更高的MMSE和更好的延迟回忆得分相关。这种关联在协变量调整后仍然存在。在调整前后，更多的情感支持与更好的功能状态相关。相比之下，社交网络与认知变化没有纵向联系，有两个反直觉的例外：更频繁的接触和更多的情感支持与调整后更差的延迟回忆和IADL评分有关。社会网络与认知或iadl之间没有纵向关联的证据，尽管存在明显的横向关联。总之，这些发现表明，在认知和功能下降的个体中出现的社会孤立，而不是社会网络的保护作用。
To determine whether more frequent engagement in larger social networks, and more emotional support protect against cognitive and functional decline with aging. We examined the influence of social networks on cognition and instrumental activities of daily living (IADLs) over a median interval of 10.9 years. Data were from the Baltimore follow-up of the Epidemiologic Catchment Area (ECA) study, a community-based sample of adults in eastern Baltimore. 874 participants completed cognitive testing at both the third and fourth study waves (1993–1996 and 2003–2004) on the Mini-Mental State Examination (MMSE) and a delayed word recall task. Functional status at both waves was self-reported on the Lawton-Brody IADL scale. Social network characteristics, assessed at the third study wave, included network size, frequency of contact, and emotional support. In cross-sectional analyses at wave 3, larger networks were associated with higher MMSE and better delayed recall scores. This association persisted after adjustment for covariates. More emotional support was associated with better functional status, before and after adjustment. By contrast, social networks were not longitudinally associated with cognitive change, with two counter-intuitive exceptions: more frequent contact and more emotional support were associated with worse delayed recall and IADL scores after adjustment. There was no evidence of a longitudinal association between social networks and cognition or IADLs, although a clear cross-sectional association exists. Together, these findings suggest the emergence of social isolation in individuals declining in cognition and functioning, rather than a protective effect of social networks.
