Caregivers of persons with dementia report worse sleep when compared to the general population. The objective of this review was to synthesize evidence regarding the link between caregiver burden and dementia caregivers' sleep.
We conducted a scoping review using a systematic search for pertinent literature in PubMed, CINAHL, and Web of Science through March 2022. Keywords included content areas of dementia, caregiver burden, and sleep. Inclusion criteria were informal caregivers of persons living with dementia, a measured relationship between informal dementia caregiver sleep and subjective caregiver burden variables, and original research. Non-English studies were excluded. Extracted data were organized in tables, compared, and synthesized.
The search yielded 540 nonduplicate articles screened by title and abstract; 118 full-text articles were reviewed; 24 were included. Most studies were cross-sectional, with variable sample sizes. Dementia caregivers had significantly poorer overall perceived sleep than noncaregivers across 4 studies that examined self-reported sleep measures. Eighteen studies investigated the association between caregiver burden and self-reported sleep quality, with 14 reporting a significant positive association between caregiver burden and self-reported sleep quality, and 4 finding null results. Only 2 of the 4 studies reporting the association between caregiver burden and objective sleep parameters (ie, actigraphy and polysomnography) reported a significant positive association for at least one sleep subdomain.
Although subjective sleep quality is commonly affected by dementia caregiving burden, there is a lack of corresponding evidence on the relationship between burden and objective sleep metrics. Healthcare providers should consider the dementia caregiver burden's impact on sleep and regularly assess caregivers' sleep difficulties. Future studies should focus on consistently measuring caregiver burden and sleep to promote dementia caregiver health and well-being.
与普通人群相比，痴呆症患者的照料者报告睡眠质量更差。本综述的目的是综合有关照料者负担与痴呆症照料者睡眠之间联系的证据。
我们进行了一项范围综述，通过系统检索截至2022年3月的PubMed、CINAHL和科学网中的相关文献。关键词包括痴呆症、照料者负担和睡眠的内容领域。纳入标准为痴呆症患者的非正式照料者、非正式痴呆症照料者睡眠与主观照料者负担变量之间的测量关系以及原创研究。排除非英文研究。提取的数据整理成表格，进行比较和综合。
检索得到540篇经标题和摘要筛选的非重复文章；对118篇全文进行了审阅；纳入24篇。大多数研究为横断面研究，样本量各不相同。在4项检查自我报告睡眠指标的研究中，痴呆症照料者总体上感知到的睡眠明显比非照料者差。18项研究调查了照料者负担与自我报告睡眠质量之间的关联，其中14项报告照料者负担与自我报告睡眠质量之间存在显著正相关，4项结果为无关联。在报告照料者负担与客观睡眠参数（即活动记录仪和多导睡眠图）之间关联的4项研究中，只有2项报告至少一个睡眠子领域存在显著正相关。
虽然主观睡眠质量通常受痴呆症照料负担影响，但缺乏关于负担与客观睡眠指标之间关系的相应证据。医疗保健提供者应考虑痴呆症照料者负担对睡眠的影响，并定期评估照料者的睡眠困难。未来的研究应专注于持续测量照料者负担和睡眠，以促进痴呆症照料者的健康和福祉。
