背景。老龄化研究中存在的方法学挑战阻碍了我们对少数民族老年人认知功能的评估。我们的目的是报告美国华人老年人的五项认知功能测试的综合得分，并检查认知功能与关键社会人口学特征之间的关系。芝加哥华人老年人口研究纳入了3159名居住在社区的中国老年人的流行病学队列。我们进行了五项认知功能测试，包括中国迷你精神状态测试、东波士顿记忆测试的即时和延迟回忆、数字广度向后评估和符号数字模态测试。我们使用Spearman相关系数来检验认知功能与社会人口学变量之间的相关性。使用线性回归模型报告社会人口学和健康变量（包括年龄、性别、教育程度）对认知功能的影响。我们的多变量分析表明，每个认知功能领域的表现与年龄呈负相关，与教育呈正相关。在性别方面，在调整了年龄、教育程度和模型中提供的所有关键变量后，男性与整体认知得分和工作记忆呈正相关。结婚，少生孩子，在美国生活的时间更短，在社区生活的时间更短，自我报告的健康状况与所有认知功能领域呈正相关。这项以美国华人老年人为基础的研究是第一批对五项认知功能测试进行测试的研究之一，这些测试使研究人员能够获得广泛的认知表现。
Background. Existing methodological challenges in aging research has dampened our assessment of cognitive function among minority older adults. We aim to report the composite scores of five cognitive function tests among U.S. Chinese older adults, and examine the association between cognitive function and key sociodemographic characteristics.Methods. The Population Study of Chinese Elderly in Chicago Study enrolled an epidemiological cohort of 3,159 community-dwelling Chinese older adults. We administered five cognitive function tests, including the Chinese Mini-Mental State Examination, the immediate and delayed recall of the East Boston Memory Test, the Digit Span Backwards assessment, and the Symbol Digit Modalities Test. We used Spearman correlation coefficients to examine the correlation between cognitive function and sociodemographic variables. Linear regression models were used to report the effect of sociodemographic and health variables including age, sex, education on cognitive function.Results. Our multivariate analysis suggested that performance in each domain of cognitive function was inversely associated with age and positively related to education. With respect to sex, after adjusted for age, education and all key variables presented in the model, being male was positively related to global cognitive score and working memory. Being married, having fewer children, having been in the United States for fewer years, having been in the community for fewer years, and better self-reported health were positively correlated with all cognitive function domains.Conclusions. This population-based study of U.S. Chinese older adults is among the first to examine a battery of five cognitive function tests, which in aggregate enables researchers to capture a wide range of cognitive performance.
