探讨采用文献计量学分析我国儿童肠道菌群领域的研究热点、发展脉络与前沿趋势。

选择中国知网、万方医学网、维普中文期刊服务平台各数据库建库至2025年12月31日的儿童肠道菌群研究相关中文文献为研究对象。采用CiteSpace 6.4R1软件，对检索、筛选出的文献进行作者合作网络与关键词共现、聚类、时间线及突现分析，构建可视化图谱。

根据本研究制定的检索策略，共计检索到儿童肠道菌群研究相关中文文献为3 173篇，经筛选，最终符合本研究文献纳入与排除标准的文献为2 747篇。我国儿童肠道菌群研究领域发文量呈"启动-发展-爆发"3阶段增长趋势，2025年发文量为563篇，达到峰值。截至2025年12月31日，本研究结果如下。①形成以张琳、郑跃杰、李玉霞等为核心的作者合作网络。②高频关键词涵盖肠道菌群、儿童、益生菌等。③关键词聚类分析前3位聚类标签依次为#0免疫功能、#1肠道菌群、#2婴幼儿。④关键词时间线图谱可见本领域近5年研究热点聚焦于肠道菌群与儿童消化、神经等多系统疾病的关联研究，涵盖功能性便秘、支气管哮喘、孤独症谱系障碍、抽动障碍等临床主题，同时高通量测序、小儿推拿等技术研究热度持续上升。⑤关键词突现分析可见腹泻、小儿腹泻、婴幼儿腹泻等关键词突现强度高，功能性消化不良、肥胖、反复呼吸道感染等是本领域近年新兴研究热点。

我国儿童肠道菌群领域研究热度持续上升，目前研究热点聚焦于肠道菌群与消化、神经、免疫系统等多系统疾病的关联及干预研究。以小儿推拿为代表的中医特色疗法是国内该领域的研究特色。未来研究应深化机制探索，推动该领域研究从现象关联向精准干预转型。

To explore the research hotspots, developmental trajectory, and frontier trends in the field of pediatric gut microbiota in China through bibliometric analysis.

Relevant Chinese literature on pediatric gut microbiota, retrieved from the CNKI, Wanfang Medical Online, and VIP database from the inception of each database to December 31, 2025, was selected as the research subjects. CiteSpace 6.4R1 software was used to perform author collaboration network, keyword co-occurrence, clustering, timeline, and burst detection analyses on the retrieved and screened literature, and to construct visualized maps.

According to the retrieval strategy established in this study, a total of 3 173 Chinese literature articles related to research on pediatric gut microbiota were retrieved. After screening, 2 747 articles were ultimately included for analysis. The number of publications in this field in China exhibited a three-stage growth trend of " initiation-development-explosion", reaching a peak of 563 articles in 2025. Up to December 31, 2025, the results of this study were as follows. ①A core author collaboration network was formed, centered around Zhang Lin, Zheng Yuejie, Li Yuxia, and so on. ②High-frequency keywords included gut microbiota, children, probiotics, and so on. ③Keyword cluster analysis revealed the top three cluster labels as #0 immunity, #1 gut microbiota, and #2 infants. ④The keyword timeline map analysis indicated that recent research hotspots focused on the association between gut microbiota and pediatric digestive, neurological, and other multisystem diseases, covering clinical topics such as functional constipation, bronchial asthma, autism spectrum disorder, and tic disorders in children. Meanwhile, the research interest in high-throughput sequencing and pediatric massage techniques continued to rise. ⑤Keyword burst analysis showed high burst intensity for terms like diarrhea, pediatric diarrhea, and infant diarrhea, while functional dyspepsia, obesity, and recurrent respiratory infections emerged as new research hotspots in the field in recent years.

Research on pediatric gut microbiota in China continues to gain momentum, with current research focusing on the association between gut microbiota and digestive, neurological, immune and other multisystem diseases, as well as intervention studies. Traditional Chinese medicine therapies, such as pediatric massage, are a distinctive feature of this research in China. Future research should delve deeper into the mechanisms underlying these themes, driving the field to shift from phenomenological correlations to precise interventions.
