The objective of this study was to validate categories of cognitive functioning using data from the 2009 Canadian Community Health Survey (CCHS)--Healthy Aging Cognition Module.
Four measures of cognitive functioning--immediate and delayed recall (memory), and animal-naming and the Mental Alternation Test (executive functioning)--were coded into five categories for the Canadian household population aged 45 or older. The scores for each measure were standardized to t-scores that controlled for age, sex and education. Respondents were classified into five cognitive functioning categories. Cross-tabulations, stratum-specific likelihood ratios and multinomial logit regression were used to assess associations between levels of cognitive functioning and various health outcomes: self-reported general and mental health status, memory and problem-solving ability, activities of daily living, life satisfaction, loneliness, depression, and chronic conditions.
Results supported the use of five levels of cognitive functioning for all four outcomes on the CCHS--Healthy Aging sample overall and by age group (45 to 64, 65 or older) and language group (English, French).
These categories can be used in future work on cognitive functioning based on the CCHS--Healthy Aging.
本研究的目的是使用 2009 年加拿大社区健康调查（CCHS）——健康老龄化认知模块的数据来验证认知功能的类别。
对认知功能的四项衡量指标——即时和延迟回忆（记忆）、动物命名和心理转换测试（执行功能）——进行了编码，将加拿大 45 岁及以上的家庭人口分为五类。每个衡量指标的得分都被标准化为 t 分数，以控制年龄、性别和教育因素。将受访者分为五个认知功能类别。交叉表、特定层的似然比和多项逻辑回归用于评估认知功能水平与各种健康结果之间的关联：自我报告的一般和心理健康状况、记忆和解决问题的能力、日常生活活动、生活满意度、孤独感、抑郁和慢性疾病。
结果支持在 CCHS——健康老龄化样本中以及按年龄组（45 至 64 岁、65 岁及以上）和语言组（英语、法语）使用认知功能的五个水平来衡量所有四个结果。
这些类别可用于基于 CCHS——健康老龄化的认知功能的未来研究。
