One new case of dementia is detected every 4 seconds and no effective drug therapy exists. Effective behavioural strategies to promote healthy cognitive ageing are thus essential. Three behaviours related to cognitive health which we all engage in daily are physical activity, sedentary behaviour and sleep. These time-use activity behaviours are linked to cognitive health in a complex and dynamic relationship not yet fully elucidated. Understanding how each of these behaviours is related to each other and cognitive health will help determine the most practical and effective lifestyle strategies for promoting healthy cognitive ageing. In this review, we discuss methods and analytical approaches to best investigate how these time-use activity behaviours are related to cognitive health. We highlight four key recommendations for examining these relationships such that researchers should include measures which (1) are psychometrically appropriate; (2) can specifically answer the research question; (3) include objective and subjective estimates of the behaviour and (4) choose an analytical method for modelling the relationships of time-use activity behaviours with cognitive health which is appropriate for their research question.
每4秒钟就会检测出一例新的痴呆症病例，且目前尚无有效的药物治疗方法。因此，有效的行为策略对于促进健康的认知老化至关重要。我们每天都会进行的与认知健康相关的三种行为是体育活动、久坐行为和睡眠。这些时间利用活动行为与认知健康之间存在着复杂而动态的关系，尚未完全阐明。了解这些行为中的每一种如何相互关联以及与认知健康的关系，将有助于确定促进健康认知老化的最实用和有效的生活方式策略。在这篇综述中，我们讨论了最佳研究这些时间利用活动行为与认知健康之间关系的方法和分析方法。我们强调了研究这些关系的四项关键建议，即研究人员应采用以下措施：（1）在心理测量上合适；（2）能够具体回答研究问题；（3）包括对行为的客观和主观评估；（4）选择一种适合其研究问题的分析方法来模拟时间利用活动行为与认知健康之间的关系。
