Along with the development of aging, much attention has been paid to geriatric health issues in China. Sleep disturbance is a common sleep problem endangering older people's health.

To systematically assess the prevalence of sleep disturbances in Chinese older people.

Studies about sleep disturbance in Chinese elderly were searched in database of CNKI, CQVIP, SinoMed, WanFang Data, PubMed, EmBase, The Cochrane Library, Web of Knowledge and PsycINFO from inception to 31st May, 2021. Two reviewers independently screened literature, extracted data and assessed risk of bias of included studies using the 11 criteria recommended by the Agency for Healthcare Research and Quality. Stata 16.0 was used for meta-analysis.

A total of 91 studies, with a sample of 81 354 cases were included. Meta-analysis showed that the overall prevalence rate of sleep disturbances among Chinese older people was 46.0%〔95%CI (41.7%, 50.4%) 〕. Further analysis indicated that the prevalence of sleep disturbances among men and women was 40.0%〔95%CI (30.9%, 49.2%) 〕and 49.4%〔95%CI (42.8%, 55.9%) 〕, respectively. And it was 35.1%〔95%CI (28.8%, 41.4%) 〕 for the 60-70-year-olds, 46.1%〔95%CI (33.8%, 58.4%) 〕 for the 70-80-year-olds, and 44.4%〔95%CI (32.7%, 56.2%) 〕 for the 80-and-over-year-olds. The sleep disturbance prevalence rate among those living in urban and rural areas was 41.5%〔95%CI (32.8%, 50.2%) 〕and 44.0%〔95%CI (36.4%, 51.7%) 〕, respectively. And it was 46.3%〔95%CI (37.6%, 55.1%) 〕for those with junior high school or lower education level, and 37.9%〔95%CI (26.7%, 49.1%) 〕for those with senior high school or higher education level. Meta-regression analysis showed that marital status and chronic disease prevalence were associated with sleep disturbances (P<0.05) .

The prevalence of sleep disturbances in Chinese older people is high. To reduce the risk of sleep disturbances and improve the sleep quality in this group, the prevention and intervention of sleep disturbances should be valued and targeted interventions should be delivered.

随着我国老龄化程度的加深，老年人群的健康问题越来越受到重视。睡眠障碍作为常见问题之一，危害着老年人群的健康。

系统评估中国老年人睡眠障碍的发生情况。

2021-05-31至2021-06-16，计算机检索中国知网、维普网、万方数据知识服务平台、中国生物医学文献数据库、PubMed、EmBase、The Cochrane Library、Web of Knowledge和PsycINFO数据库，搜集关于中国老年人睡眠障碍情况的研究，检索不限起始时间，截止日期为2021-05-31。由2名研究者独立筛选文献，提取资料并评价纳入研究的偏倚风险（使用美国卫生保健质量和研究机构推荐的11条标准进行偏倚风险评价）后，采用Stata 16.0软件进行Meta分析。

共纳入91篇研究，纳入研究的总样本量为81 354例，其中有睡眠障碍者32 802例。Meta分析结果显示，我国老年人的睡眠障碍患病率为46.0%〔95%CI（41.7%，50.4%）〕。亚组分析结果显示，男性和女性的睡眠障碍患病率分别为40.0%〔95%CI（30.9%，49.2%）〕、49.4%〔95%CI（42.8%，55.9%）〕；年龄60~70、>70~80、>80岁组睡眠障碍患病率分别为35.1%〔95%CI（28.8%，41.4%）〕、46.1%〔95%CI（33.8%，58.4%）〕、44.4%〔95%CI（32.7%，56.2%）〕；城市和农村地区的睡眠障碍患病率分别为41.5%〔95%CI（32.8%，50.2%）〕、44.0%〔95%CI（36.4%，51.7%）〕；受教育程度是初中及以下和高中及以上的睡眠障碍患病率分别为46.3%〔95%CI（37.6%，55.1%）〕、37.9%〔95%CI（26.7%，49.1%）〕。Meta回归分析结果显示，婚姻状态、患慢性病情况是我国老年人睡眠障碍患病率的影响因素（P<0.05）。

我国老年人睡眠障碍患病率较高，应重视老年人睡眠障碍的预防和干预工作，有针对性地采取综合干预措施，以改善老年人睡眠质量，降低老年人睡眠障碍发生风险。
