This review will determine the prevalence of sleep disturbances in individuals with mild cognitive impairment.
Mild cognitive impairment is regarded as a transitional state between normal functioning and dementia, and has a high likelihood of conversion to dementia. Individuals with mild cognitive impairment may suffer more severe sleep disturbances compared with normal older people. In some studies, sleep disturbances were associated with significantly higher odds of mild cognitive impairment. There is a need for prevalence estimates of sleep disturbances in people with mild cognitive impairment based on the currently available literature to guide clinical health care professionals and public health policies.
The review will consider studies reporting on the prevalence of sleep disturbances in individuals with mild cognitive impairment, using validated instruments, including subjective and/or objective measures. Studies will be excluded if the participants report sleep-related breathing or movement disorders. Studies using only the Mini-Mental State Examination to diagnose mild cognitive impairment will also be excluded.
The review will follow the JBI methodology for systematic reviews of prevalence and incidence. The MEDLINE (Ovid), Embase, Cochrane Library (CDSR and CENTRAL), CINAHL (EBSCOhost), PsycINFO (EBSCOhost), Scopus, and Web of Science Core Collection databases will be systematically searched from inception to the present with no language limitations. Analytical observational studies, including prospective and retrospective cohort, case-control, and cross-sectional studies, will be considered. Two reviewers will independently conduct the study selection, critical appraisal, and data extraction. Methodological quality will be evaluated using the JBI critical appraisal checklist for studies reporting prevalence data. A meta-analysis will be conducted to synthesize the prevalence data, where possible.

本综述旨在确定轻度认知障碍个体中睡眠障碍的患病率。
轻度认知障碍被认为是正常功能和痴呆之间的过渡状态，且向痴呆转化的可能性较高。与正常老年人相比，轻度认知障碍个体可能遭受更严重的睡眠障碍。在一些研究中，睡眠障碍与轻度认知障碍的发生风险显著增加相关。基于现有文献，需要对轻度认知障碍患者睡眠障碍的患病率进行评估，以指导临床医护人员和公共卫生政策。
本综述将纳入报告使用经过验证的工具（包括主观和/或客观测量）评估轻度认知障碍个体睡眠障碍患病率的研究。如果参与者报告与睡眠相关的呼吸或运动障碍，则将排除这些研究。仅使用简易精神状态检查表诊断轻度认知障碍的研究也将被排除。
本综述将遵循 JBI 对患病率和发病率的系统评价方法。将对 MEDLINE（Ovid）、Embase、Cochrane 图书馆（CDSR 和 CENTRAL）、CINAHL（EBSCOhost）、PsycINFO（EBSCOhost）、Scopus 和 Web of Science 核心合集数据库进行系统检索，检索时间从建库开始至当前，不设语言限制。将考虑使用前瞻性和回顾性队列研究、病例对照研究和横断面研究的分析性观察研究。两名评审员将独立进行研究选择、批判性评价和数据提取。将使用 JBI 对报告患病率数据的研究进行批判性评价检查表来评估方法学质量。在可能的情况下，将进行荟萃分析以综合患病率数据。
