The concept of intrinsic capacity (IC) revolves around healthy aging and active aging. Since the Introduction of the concept by the World Health Organization in 2015, a series of studies have been conducted by scholars from multiple fields. However, no bibliometric analysis has systematically investigated this issue. We aim to identify the current landscape and frontier trends of scientific achievements on IC in older adults through bibliometric approaches.
Quantitative analysis of publications relating to IC in older adults from 2015 to 2023 was interpreted and graphed through the Web of Science Core Collection database on December 5, 2023. A variety of quantitative variables was analyzed, including publication and citation counts, H-index, and journal citation reports. Co-authorship, citation, co-citation, and co-occurrence analyses were performed for countries/regions, institutions, authors, and keywords using the VOSviewer and CiteSpace.
A total of 952 original and review articles in English were identified. The European countries possessed an absolute advantage in this field. The most contributive institution was the University of São Paulo. The most productive author is Cesari Matteo from France, followed by Qaisar Rizwan from the United Arab Emirates. However, a relatively low level of research cooperation existed between institutions and authors. Important topics mainly include the connotations, theoretical framework models, evaluation, screening tools, and application scenarios of IC. Among the promising hotspots, "biological aging", "ICOPE", "Covid-19", "prevention", "inflammation", "caf22", "prevalence", and "randomized controlled trial" displayed relatively latest average appearing year.
Global trends indicate a growing scientific output on IC in older adults, and developed countries are leading the way. There is still room for improvement in research team collaboration. The focus gradually shifts from theoretical research to empirical research. It is recommended to pay attention to the latest hot spots, such as "biological aging", "ICOPE implementation", "post-COVID-19 syndrome", and "biomarkers".
内在能力（IC）的概念围绕健康老龄化和积极老龄化展开。自世界卫生组织于2015年引入该概念以来，多个领域的学者开展了一系列研究。然而，尚无文献计量分析对这一问题进行系统研究。我们旨在通过文献计量方法确定老年人IC科学成果的当前格局和前沿趋势。
2023年12月5日，通过科学网核心合集数据库对2015年至2023年期间与老年人IC相关的出版物进行定量分析，并绘制图表。分析了各种定量变量，包括发表和被引次数、H指数以及期刊引证报告。使用VOSviewer和CiteSpace对国家/地区、机构、作者和关键词进行合著、引文、共被引和共现分析。
共识别出952篇英文原创和综述文章。欧洲国家在该领域具有绝对优势。贡献最大的机构是圣保罗大学。产出最多的作者是来自法国的切萨里·马泰奥，其次是来自阿联酋的凯萨尔·里兹万。然而，机构和作者之间的研究合作水平相对较低。重要主题主要包括IC的内涵、理论框架模型、评估、筛查工具和应用场景。在有前景的热点中，“生物衰老”“ICOPE”“新冠疫情-19”“预防”“炎症”“caf22”“患病率”和“随机对照试验”的平均出现年份相对较新。
全球趋势表明，关于老年人IC的科学产出不断增加，发达国家处于领先地位。研究团队合作仍有改进空间。重点逐渐从理论研究转向实证研究。建议关注最新热点，如“生物衰老”“ICOPE实施”“新冠后综合征”和“生物标志物”。
