Abstract

Objective

Sleep is one of the most important needs for humans and is negatively affected by age. Executive functioning is a key element of cognition that also faces attrition with ageing. Therefore, this study aimed to determine the relationship between sleep quality and different aspects of executive function in older adults using specialised tests for deep assessment.

Methods

This descriptive study sampled 100 older individuals aged 60 years or older enrolled in an adult day care centre. Self-reported sleep status was collected using the Pittsburgh Sleep Quality Index (PSQI). Aspects of executive functioning were recorded using the Tower of London test (TOL), the Wisconsin Card Sorting Test (WCST) and the Trail Making Test (TMT). Performance on these tests was compared by sleep status using hierarchical regression.

Results

Sleep status was independently associated with poorer executive functioning, indicated by perseverative errors, categories and incorrect replacement on the Wisconsin Card Sorting Test, as well as the Trail Making Test B. Additionally there was no significant interaction between the Tower of London Test score and sleep status.

Conclusions

This study indicates a significant association between sleep status and some aspects of executive function. These findings highlight the importance of sleep quality on cognitive performance in older adults.

睡眠质量对伊朗老年人执行功能不同方面的影响

目的睡眠是人类最重要的需求之一，并受到年龄的负面影响。执行功能是认知的一个关键要素，随着年龄的增长，它也面临着损耗。因此，本研究旨在通过深度评估的专门测试来确定老年人睡眠质量与执行功能不同方面之间的关系。方法本描述性研究抽样100名60岁或以上的老年人在成人日托中心登记。使用匹兹堡睡眠质量指数（PSQI）收集自我报告的睡眠状态。使用伦敦塔测试（TOL）、威斯康辛卡片分类测试（WCST）和轨迹测试（TMT）记录执行功能的各个方面。在这些测试中的表现通过睡眠状态使用层次回归进行比较。结果睡眠状态与较差的执行功能独立相关，表现为威斯康辛卡片分类测试中的持续性错误、分类和不正确替换，以及轨迹制作测试b。此外，伦敦塔测试成绩与睡眠状态之间没有显著的相互作用。结论：本研究表明睡眠状态与执行功能的某些方面存在显著关联。这些发现强调了睡眠质量对老年人认知能力的重要性。
