目的 针对社区中老年人的社会衰弱（social frailty,SF）发生率进行系统回顾和Meta分析，为制订公共卫生战略决策提供循证依据。 方法 检索PubMed、Web of Science、EMBASE、CINAHL Plus、PsycINFO、Cochrane Library、中国知网、中国生物医学文献数据库、万方、维普等数据库，检索时间为建库至2022年8月30日。由2名研究者分别筛选文献、提取资料并评价纳入文献的偏倚风险后，采用Stata 15.1软件进行统计分析。 结果 共有24项研究符合纳入标准，包括54 563位参与者。老年人SF和SF前期发生率分别为16.8%（95%CI：0.118~0.218）和36.6%（95%CI：0.330~0.402）。亚组分析结果显示，女性、欧洲、横断面研究、评估工具为社会衰弱问卷（social frailty questionnaire，SFQ）和样本量≤500的SF发生率更高（均P＜0.05）。 结论 SF在老年人中较为常见，应引起社区医护人员和卫生政策制订者的重视，需继续开展相关研究并制订干预措施，促进健康老龄化。

Objective To conduct a systematic review and meta-analysis of the incidence of social frailty among the elderly in the community,and to provide evidence-based reference for future public health strategic decision-making. Methods Databases including PubMed，Web of Science，EMBASE，CINAHL Plus，PsycINFO，Cochrane Library databases，CNKI，CBM，WanFang，and VIP were searched.The retrieval time was from the inception to August 30,2022.Literature screening,data extraction and the bias risk evaluation were conducted by 2 researchers independently,and Stata 15.1 software was used for meta-analysis. Results A total of 24 studies met the inclusion criteria,involving 54,563 participants.The pooled incidence of social frailty and social prefrailty in community-dwelling elderly populations was 16.8%（95%CI：0.118~0.218）and 36.6%（95%CI：0.330~0.402）,respectively. Results of subgroup analysis showed a higher incidence of social frailty in women,Europe,cross-sectional studies,an assessment tool of social frailty questionnaire and sample size ≤500(all P＜0.05). Conclusions Social frailty is more common in the elderly,which should arouse the attention of community medical personnel and health policy makers.Continued research and interventions are needed to promote healthy ageing.
