OBJECTIVES: To systematically assess the prevalence of decreased intrinsic capacity in older adults, stratified by relevant factors such as country, sex, sample source, and region. METHODS: We conducted a comprehensive search of PubMed, Web of Science, EMBASE, The Cochrane Library, PsychINFO, CINAHL, China Knowledge Resource Integrated Database, Wanfang Database, Weipu Database, and Chinese Biomedical Database to collect studies published on the decline of intrinsic capacity in older adults before February 24, 2023. The results of the study were analyzed using the Stata 15.0 software package, using a random-effects model to estimate the pooled detection rate of decreased intrinsic capacity in older adults. The Joanna Briggs Institute Critical Appraisal Tool was used to assess the quality of all included studies. RESULTS: A total of 16 studies (67,881 older adults in 4 countries) were included. The results showed that the pooled detection rate of decreased intrinsic capacity in older adults was 76.1% (95% CI: 68.0%-84.2%). The 16 studies had obvious heterogeneity, and further subgroup analysis showed that the detection rate of decreased intrinsic capacity in older adults was higher in developed countries, females, and hospitals. Thirteen studies found that the pooled detection rate was 73.7% (95%: CI 64.5%-82.8%) for decreased intrinsic capacity in Chinese older adults, with higher rates in mainland China and Hong Kong than in Taiwan. CONCLUSIONS: Our study suggests that intrinsic capacity declines more rapidly in older adults. Understanding the degree of decline in the intrinsic capacity of older adults will help to provide an important basis for the formulation and development of care policies for older adults.

目的：系统评估老年人内在能力下降的流行率，并按国家、性别、样本来源和地区等相关因素进行分层。
方法：我们全面检索了 PubMed、Web of Science、EMBASE、The Cochrane Library、PsychINFO、CINAHL、中国知识资源总库、万方数据库、维普数据库和中国生物医学文献数据库，以收集截至 2023 年 2 月 24 日发表的关于老年人内在能力下降的研究。使用 Stata 15.0 软件包对研究结果进行分析，采用随机效应模型估计老年人内在能力下降的总检出率。使用 Joanna Briggs 研究所的批判性评估工具评估所有纳入研究的质量。
结果：共纳入 16 项研究（4 个国家的 67881 名老年人）。结果显示，老年人内在能力下降的总检出率为 76.1%（95%CI：68.0%-84.2%）。16 项研究存在明显的异质性，进一步的亚组分析显示，发达国家、女性和医院老年人内在能力下降的检出率较高。13 项研究发现，中国老年人内在能力下降的总检出率为 73.7%（95%CI：64.5%-82.8%），其中中国大陆和香港的检出率高于台湾。
结论：本研究表明，老年人内在能力下降得更快。了解老年人内在能力下降的程度将有助于为制定和发展老年人护理政策提供重要依据。
