To examine predictors of membership in discordant groups identified by subjective and objective measures of cognitive function. Participants in the Study of Older Korean Americans ( = 2046) were classified according to their subjective cognitive ratings (// vs. /) and Mini-Mental State Examination scores (normal cognition vs. cognitive impairment), yielding two discordant groups: (1) positive ratings but cognitive impairment and (2) negative ratings but normal cognition. Logistic regression models examined how the discordant group membership was associated with personal resources. Among those with positive cognitive ratings, the odds of belonging to the discordant group were associated with low personal resources (advanced age and lower levels of education, acculturation, and knowledge about Alzheimer's disease). However, an opposite pattern was observed among those with negative ratings. The pattern of discordance suggests ways to promote early detection of cognitive impairment and close the gap in cognitive health care.
探讨通过主观和客观认知功能测量确定的认知功能不一致群体的预测因素。
本研究纳入了韩国老年人研究中的 2046 名参与者，根据其主观认知评定（正常 vs. 异常）和简易精神状态检查评分（正常认知 vs. 认知障碍）进行分组，产生了两个认知功能不一致的群体：（1）认知障碍但主观评定正常；（2）主观认知评定异常但认知正常。采用逻辑回归模型检验认知功能不一致群体与个人资源之间的关系。在认知评定正常的人群中，属于认知功能不一致群体的可能性与个人资源较低有关（年龄较大、受教育程度较低、文化程度较低以及对阿尔茨海默病的了解程度较低）。然而，在认知评定异常的人群中观察到了相反的模式。认知功能不一致的模式提示了一些方法，可以促进认知障碍的早期发现，并缩小认知保健方面的差距。
