![]() ![]() ![]() Results were limited to papers published between January 1, 1980, and February 10, 2020, because the concept of MCI was proposed firstly between the early and mid-1980s. Moreover, references of relevant literatures were scanned carefully to determine any articles missed. The title and abstract of the articles were read firstly, and then the full-text article was read if it was not possible to identify the eligibility of a paper from the abstract. The search strategy used Mesh phrases and words such as “cognitive dysfunction, mild cognitive impairment, MCI, mild neurocognitive disorder, prevalence, epidemiology, China, and Chinese.” In order to reflect the epidemiology of MCI comprehensively, we searched all relevant literatures with an update in February 10, 2020. Published studies were identified by systematically searching PubMed, Excerpta Medica Database (EMBASE), China National Knowledge Infrastructure (CNKI), Wanfang Database, Chongqing VIP (CQVIP) Database, and China Biology Medicine disc (CBMdisc). In further studies, screening tools and diagnosis criteria should be considered when estimating MCI prevalence. Conclusions: The prevalence of MCI in China was 15.4%, which varied by demographics, lifestyles, morbidity, screening tools, and diagnostic criteria. Besides, women, older adults, illiterate people, rural residents, and those who lived with unhealthy lifestyles and morbidity showed higher prevalence. According to different diagnostic criteria, the prevalence was 14.8% (95% CI: 12.2–17.6%) for Petersen criteria, 15.0% (95% CI: 12.7–17.5%) for DSM-IV, and 21.2% (95% CI: 17.5–25.2%) for Chinese Expert Consensus on Cognitive Impairment (CECCI). Subgroup analyses indicated that the prevalence calculated with different screening tools was 20.2% (95% CI: 15.1–25.9%) for Montreal Cognitive Assessment (MoCA) and 13.0% (95% CI: 10.7–15.5%) for Mini-Mental State Examination (MMSE). The pooled prevalence of MCI among Chinese elderly was 15.4% (95% CI: 13.5–17.4%). Results: Fifty-three studies with 123,766 subjects were included. The quality assessment was conducted via external validity, internal validity, and informativity, the pooled prevalence was calculated through the random-effect model, and the homogeneity was evaluated by Cochran’s Q test and I 2. Methods: PubMed, EMBASE, CNKI, Wanfang, CQVIP, and CBMdisc were searched for studies on prevalence of MCI among Chinese elderly between January 1, 1980, and February 10, 2020. Objective: A systematic review and meta-analysis was conducted to estimate the pooled MCI prevalence among the population aged 55 years and older in China. The prevalence of MCI in China varied across studies with different screening tools and diagnostic criteria. Background: Mild cognitive impairment (MCI) induced the majority number of dementia patients. ![]()
