Background 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. Objective To systematically assess the prevalence of sleep disturbances in Chinese older people. Methods 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. Results 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) . Conclusion 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.
