【摘要】 目的 通过meta分析并探讨我国养老机构老年人衰弱患病率的总体情况，为养老机构老年人衰弱问题的防治以及相关政策的制定提供依据。方法 计算机检索中国知网（CNKI）、万方数据库（WF）、维普中文期刊数据库（VIP）、中国生物医学文献数据库（CBM）、PubMed、EMbase、Web of Science和The Cochrane Library，检索自建库以来所公开发表的与我国养老机构老年人衰弱有关的文献，所提取数据使用Stata 14.0软件进行meta分析。结果 本次分析共纳入24篇文献，总样本量为7 697例，通过meta分析得出我国养老机构老年人衰弱患病率为51.0%(95%CI=45.1%～56.9%)，衰弱前期患病率为40.5%(95%CI=31.5%～49.5%)。亚组分析结果显示，我国养老机构老年人中女性衰弱患病率（48.3%）高于男性（41.5%）；年龄>80岁的老年人衰弱患病率（51.5%）最高，60～<70岁老年人的衰弱患病率（41.8%）高于70～<80岁的老年人（38.6%）；在我国各地区中，中南地区养老机构的老年人衰弱患病率最高（57.1%）；在不同的衰弱筛查工具中，使用多维度筛查工具蒂尔堡衰弱指标（Tilburg frailty indicator,TFI）得出的养老机构老年人衰弱患病率最高（60.0%）。结论 我国目前养老机构老年人衰弱的患病率较高，对养老机构老年人衰弱的防治与干预问题应多加重视，积极控制衰弱的发生与发展。更多还原

【Abstract】 Objective To understand and discuss the overall situation of the prevalence of frailty among elderly people in elderly care institutions in China through meta analysis,provide evidence for prevention and treatment of the frailty in elderly care institutions and formulation of relevant policies. Methods The computer retrieval was conducted on CNKI,Wanfang Database,VIP,CBM,PubMed,Embase,Web of Science and The Cochrane Library,to search the literature on the frailty of the elderly in Chinese nursing institutions published since the establishment of the database. The meta analysis was performed on the extracted data by the Stata 14.0 software. Results This study included 24 documents,with a total sample size of 7 697 cases. Meta-analysis showed that the prevalence of frailty among elderly people in elderly care institutions in China was 51.0%(95% CI =45.1%-56.9%),and the prevalence of pre-frailty was 40.5%(95%CI=31.5%-49.5%). The results of subgroup analysis showed that the prevalence of frailty of women in elderly care institutions in China(48.3%) higher than that of men(41.5%). The prevalence of frailty among the elderly aged over 80 years was the highest(51.5%),and the prevalence among the elderly aged 60-<70 years(41.8%) was higher than that among the elderly aged 71-<80 years(38.6%). Among all regions in China,the prevalence of frailty in elderly care institutions in central and southern China was the highest(57.1%). Among the frailty screening tools,the frailty prevalence of the elderly in institutions surveyed using Tilburg frailty indicator(TFI) was the highest(60.0%). Conclusion The prevalence rate of frailty among elderly people in elderly care institutions is high in China,and the attention should be paid to the prevention and intervention of elderly frailty in institutions,to actively control occurrence and development of elderly frailty.更多还原
