Abstract

Objectives: Cognitive reserve provides evidence in the search for answers regarding the role that lifestyle has in the protection of cognition in old age. Through a structural equations model, different things were analyzed: the relative weight of education, occupational complexity, free time activities and the intelligence quotient in cognitive reserve; and its impact on three cognitive domains: memory, language and executive functions.

Design: A trail analysis was executed, using structural equations procedure.

Participants: 167 older participants (mean = 76.74 years, standard deviation = 6.8 years).

Measurements: Participants were assessed with: Sociodemographic Questionnaire, Occupational Activity Agency Questionnaire, Social Participation Questionnaire and Neuropsychological Evaluation Battery for: memory, language and executive functions.

Results: The cognitive reserve factor is well represented by the measures included, with values between .43 and .86, and shows a direct effect on language (β = .52, p < .001), executive functions (β = .77, p <.001), and memory (β = .36, p = .003).

Conclusions: In conclusion, lifestyle factors, such as education, occupational complexity, leisure time activities and intelligence quotient have an impact on the conformation of cognitive reserve and performance in some psychological processes.

估算老年人的认知储备及其对认知表现的影响。

目的：认知储备为寻找生活方式在保护老年认知能力方面所起作用的答案提供了证据。通过结构方程模型，分析了不同的因素：教育、职业复杂性、业余活动和智商在认知储备中的相对权重；以及认知储备对记忆、语言和执行功能这三个认知领域的影响：设计：采用结构方程程序进行追踪分析：167 名老年参与者（平均年龄 = 76.74 岁，标准差 = 6.8 岁）：测量：对参与者进行评估：社会人口调查表、职业活动机构调查表、社会参与调查表和神经心理评估电池：记忆、语言和执行功能：结果：认知储备因子在所包含的测量中得到了很好的体现，其值介于 0.43 和 0.86 之间，并显示出对语言的直接影响（β = 0.52，p β = 0.77，p β = 0.36，p = 0.003）：总之，教育、职业复杂程度、业余活动和智商等生活方式因素对认知储备的形成和某些心理过程的表现有影响。
