目的 通过Meta分析明确我国老年人可逆性认知衰弱发生率及影响因素，为临床实践制订针对性的干预措施提供依据。方法 计算机检索 PubMed、Web of Science、MEDLINE、Wiley Online Library、OVID、中国知网、万方、维普、SinoMed等数据库，收集可逆性认知衰弱相关文献，采用Stata 18.0软件进行Meta分析。结果 纳入文献17篇，提取出22个影响因素。可逆性认知衰弱发生率为25.0%，抑郁、年龄、至少患有3种慢性病、多药共服、日常生活活动能力和运动锻炼是其主要影响因素(均P＜0.05）。结论 我国老年人群中可逆性认知衰弱的发生率相对较高，受多种因素综合影响，护理人员可根据这些影响因素识别高风险群体，并提供针对性干预。

Objective To determine the prevalence and influencing factors of reversible cognitive frailty (RCF) among older adults in China through a Meta-analysis,and to provide evidence for developing targeted intervention in clinical practice.Methods Databases including PubMed,Web of Science,MEDLINE,Wiley Online Library,OVID,CNKI,WanFang,VIP,and SinoMed were systematically searched to collect literature on RCF.Meta-analysis was performed using Stata 18.0 software.Results A total of 17 studies were included,from which 22 influencing factors were extracted.The prevalence of RCF was 25.0%.Depression,age,having at least 3 chronic conditions,polypharmacy,activities of daily living,and physical exercise were its main influencing factors (all P＜0.05).Conclusions The incidence of RCF among older adults in China is relatively high and is influenced by multiple factors.Nursing staff can identify high-risk groups based on these factors and provide targeted intervention.
