目的：关于老年人孤独感和社会孤立之间的不一致性，证据不足。我们的目的是调查这种不一致及其可能产生的任何健康影响。方法：使用来自爱尔兰（TILDA）和英格兰（ELSA）老龄化队列的全国代表性数据集，我们创建了孤独和社会隔离之间不一致的度量，我们称之为社会不对称。这个指标是对孤独量表和社会孤立量表的标准化得分之间的分类差异，给出了以下类别：和谐孤独和孤立，不和谐：对孤独有抵抗力，或不和谐：易受孤独影响。我们使用回归和多层次模型来确定社会不对称和认知结果之间的潜在关系。结果：在横断面和两年的随访中，社会不对称预测了认知结果，例如，不和谐：对孤独坚强的个体表现优异，但我们未能找到社会不对称作为认知轨迹随时间变化的预测因素的证据。结论：我们提出了一个与临床结果相关的新指标和初步证据。进一步的研究在不同人群中验证这一指标，并评估其与其他结果的关系，是有必要的。版权所有：John Wiley & Sons， Ltd。
Objective: Scant evidence is available on the discordance between loneliness and social isolation among older adults. We aimed to investigate this discordance and any health implications that it may have.Method: Using nationally representative datasets from ageing cohorts in Ireland (TILDA) and England (ELSA), we created a metric of discordance between loneliness and social isolation, to which we refer as Social Asymmetry. This metric was the categorised difference between standardised scores on a scale of loneliness and a scale of social isolation, giving categories of: Concordantly Lonely and Isolated, Discordant: Robust to Loneliness, or Discordant: Susceptible to Loneliness. We used regression and multilevel modelling to identify potential relationships between Social Asymmetry and cognitive outcomes.Results: Social Asymmetry predicted cognitive outcomes cross-sectionally and at a two-year follow-up, such that Discordant: Robust to Loneliness individuals were superior performers, but we failed to find evidence for Social Asymmetry as a predictor of cognitive trajectory over time.Conclusions: We present a new metric and preliminary evidence of a relationship with clinical outcomes. Further research validating this metric in different populations, and evaluating its relationship with other outcomes, is warranted. Copyright (C) 2016 John Wiley & Sons, Ltd.
