Abstract

Abstract: Aims: To clarify the specific impact paths among physical activity, activity of daily living, depression and quality of life among dementia patients. Design: A descriptive, cross‐sectional design. Methods: Dementia patients and their caregivers from five tertiary general hospitals and one dementia patients' club were recruited. A total of 216 valid questionnaires were collected from November 2018 ‐ March 2019. Path analysis was performed by Mplus 7.0 to test the casual relationship among physical activity, activity of daily living, depression and quality of life. Results: Most patients with dementia presented a low level of physical activity and suffered from impaired quality of life. The modified model presented a good model fit and revealed that physical activity had indirect positive effects on quality of life mediated by activity of daily living and depression. Conclusion: The results showed that physical activity was a promising non‐pharmacological method to improve the performance of activity of daily living and reduce depressive symptoms and then enhance the quality of life among dementia patients. Impact: The findings were beneficial to elevate the awareness of physical activity among patients and professionals. This study was helpful to understand how physical activity exerted effects on life quality of dementia patients. This study provided a new perspective for researchers to elucidate the causal relationship of variables among dementia patients. Abstract : 目的: 阐明痴呆症患者体力活动、日常生活活动、抑郁与生活质量的具体影响路径。 设计: 描述性横向设计。 方法: 从五所三级综合医院和一家痴呆症患者俱乐部招募痴呆症患者及其看护人员。自2018年11月至2019年3月, 共收集到216份有效问卷。采用Mplus 7.0进行路径分析, 以验证体力活动、日常生活活动、抑郁与生活质量之间的因果关系。 结果: 大多数痴呆症患者的体力活动水平较低, 生活质量较差。改进后的模型与情况相符, 并表明体力活动对生活质量有间接的积极影响, 其中介作用是日常生活活动和抑郁。 结论: 结果表明, 体力活动是一种改善痴呆症患者日常生活活动表现、减轻抑郁症状、提高生活质量的非药理学方法, 具有广阔的前景。 影响: 本项研究结果有助于提高患者和专业人士对体力活动的认识。本项研究有助于了解体力活动对痴呆症患者生活质量的影响。此外, 这项研究还为研究人员明确痴呆症患者各影响变量之间的因果关系提供了新的研究角度。
