Mild cognitive impairment (MCI) is commonly defined as a transitional subclinical state between normal aging and dementia. A growing body of research indicates that health behaviors may play a protective role against cognitive decline and could potentially slow down the progression from MCI to dementia. The aim of this study is to conduct a bibliometric analysis of literature focusing on health behaviors and MCI to summarize the factors and evidence regarding the influence of health behaviors on MCI.
The study performed a bibliometric analysis by retrieving publications from the Science Citation Index and Social Sciences Citation Index sub-databases within the Web of Science Core Collection. Utilizing VOSviewer and CiteSpace software, a total of 2,843 eligible articles underwent co-citation, co-keywords, and clustering analyses. This methodology aimed to investigate the current status, trends, major research questions, and potential future directions within the research domain.
The bibliometric analysis indicates that research on healthy behaviors in individuals with MCI originated in 2002 and experienced rapid growth in 2014, reflecting the increasing global interest in this area. The United States emerged as the primary contributor, accounting for more than one-third of the total scientific output with 982 articles. Journals that published the most articles on MCI-related health behaviors included "Journal of Alzheimer's Disease," "Neurobiology of Aging," "Frontiers in Aging Neuroscience," and other geriatrics-related journals. High-impact papers identified by VOSviewer predominantly cover concepts related to MCI, such as diagnostic criteria, assessment, and multifactorial interventions. Co-occurrence keyword analysis highlights five research hotspots in health behavior associated with MCI: exercise, diet, risk factors and preventive measures for dementia, cognitive decline-related biomarkers, and clinical trials.
This study provides a comprehensive review of literature on health behavior in individuals with MCI, emphasizing influential documents and journals. It outlines research trends and key focal points, offering valuable insights for researchers to comprehend significant contributions and steer future studies.
轻度认知障碍（MCI）通常被定义为正常衰老与痴呆之间的一种过渡性亚临床状态。越来越多的研究表明，健康行为可能对认知衰退起到保护作用，并有可能减缓从MCI到痴呆的进展。本研究的目的是对聚焦于健康行为与MCI的文献进行文献计量分析，以总结有关健康行为对MCI影响的因素和证据。
该研究通过从科学引文索引和社会科学引文索引子数据库中检索科学网核心合集内的出版物来进行文献计量分析。利用VOSviewer和CiteSpace软件，对总共2843篇符合条件的文章进行了共被引、共关键词和聚类分析。该方法旨在调查该研究领域的现状、趋势、主要研究问题以及潜在的未来方向。
文献计量分析表明，对MCI个体健康行为的研究始于2002年，并在2014年经历了快速增长，这反映出全球对该领域的兴趣日益增加。美国成为主要贡献者，以982篇文章占总科学产出的三分之一以上。发表关于MCI相关健康行为文章最多的期刊包括《阿尔茨海默病杂志》《衰老神经生物学》《衰老神经科学前沿》以及其他与老年医学相关的期刊。VOSviewer识别出的高影响力论文主要涵盖与MCI相关的概念，如诊断标准、评估和多因素干预。共现关键词分析突出了与MCI相关的健康行为的五个研究热点：运动、饮食、痴呆的危险因素和预防措施、与认知衰退相关的生物标志物以及临床试验。
本研究对MCI个体健康行为的文献进行了全面综述，强调了有影响力的文献和期刊。它概述了研究趋势和关键重点，为研究人员理解重要贡献并指导未来研究提供了有价值的见解。
