在这项研究中，我们使用来自爱尔兰共和国65岁及以上人口调查的数据来检查认知障碍与孤独、无聊倾向、社会关系和抑郁之间的关系，使用简短智力测试进行评估。参与者是随机选择的65岁以上居住在社区的爱尔兰人。“简易智力测试”得分为8或9分（满分为10分）被归类为“低正常”，低于8分被归类为“可能的认知障碍”。我们使用围绕潜在变量分析（CLV）的聚类来识别与认知功能降低相关的变量族。可能存在认知障碍的总体患病率为14.7% （95% CI 12.4-17.3%）。低正常评分的患病率为30.5% （95% CI 27.2-33.7%）。CLV分析确定了三组预测因素：“低社会支持”（丧偶，独居，低社会支持），“个人认知储备”（低社会活动，无休闲运动，从未结婚，孤独和无聊倾向），以及“社会人口认知储备”（小学教育，农村户籍）。在多变量分析中，这两个认知储备集群与认知功能独立相关，但与社会支持无关。孤独和无聊倾向与老年认知功能下降有关，并与认知储备相关的其他因素聚集在一起。两者可能有一个共同的潜在机制，即无法选择和保持对社会环境（孤独）或非社会环境（无聊倾向）的特定特征的注意力。
In this study, we use data from a population survey of persons aged 65 and over living in the Irish Republic to examine the relationship of cognitive impairment, assessed using the Abbreviated Mental Test, with loneliness, boredom-proneness, social relations, and depression. Participants were randomly selected community-dwelling Irish people aged 65+ years. An Abbreviated Mental Test score of 8 or 9 out of 10 was classified as 'low normal', and a score of less than 8 as 'possible cognitive impairment'. We used clustering around latent variables analysis (CLV) to identify families of variables associated with reduced cognitive function. The overall prevalence of possible cognitive impairment was 14.7% (95% CI 12.4-17.3%). Low normal scores had a prevalence of 30.5% (95% CI 27.2-33.7%). CLV analysis identified three groups of predictors: 'Low social support' (widowed, living alone, low social support), 'personal cognitive reserve' (low social activity, no leisure exercise, never having married, loneliness and boredom-proneness), and 'sociodemographic cognitive reserve' (primary education, rural domicile). In multivariate analysis, both cognitive reserve clusters, but not social support, were independently associated with cognitive function. Loneliness and boredom-proneness are associated with reduced cognitive function in older age, and cluster with other factors associated with cognitive reserve. Both may have a common underlying mechanism in the failure to select and maintain attention on particular features of the social environment (loneliness) or the non-social environment (boredom-proneness).
