户外活动与近视关系的研究趋势和热点：基于 2006 年至 2021 年 Web of Science 数据库的文献计量分析。

OBJECTIVES: This study aimed to explore the current status, hotspots, and emerging research trends regarding the relationship between outdoor activities and myopia. METHODS: Publications on the relationship between outdoor activities and myopia from 2006 to 2021 were collected from the Web of Science Core Collection database. CiteSpace (version 6.1.R2) was used to performed a bibliometric analysis, and R software (version 4.1.0) was used to visualize the trends and hot map of publications. RESULTS: A total of 640 publications were collected and analyzed in the present study. China was the major contributor ( = 204), followed by the United States of America ( = 181) and Australia ( = 137). The United States of America had the most extensive foreign cooperation (centrality = 0.25), followed by Australia (centrality = 0.20). The National University of Singapore contributed the largest number of publications ( = 48), followed by Sun Yat-Sen University ( = 41) and the Australian National University ( = 41). Among institutions, Cardiff University in the United Kingdom had the most extensive foreign cooperation (centrality = 0.12), followed by the National University of Singapore (centrality = 0.11). Saw S from Singapore had the largest number of publications ( = 39), followed by Morgan I from Australia ( = 27) and Jonas J from Germany ( = 23). & is the most important journal to study the relationship between outdoor activities and myopia. "Global Prevalence of Myopia and High Myopia and Temporal Trends from 2000 through 2050" published by Holden BA was the most cited paper in this field with 177 citations. Co-occurrence and burst analyses of keywords showed that research trends and hotspots in this field focused mainly on "risk," "prevention" and "school". CONCLUSIONS: The influence of outdoor activities on myopia remains a concern. In the future, deeper cooperation between countries or institutions is required to explore the effects of outdoor activities on myopia. Outdoor activities for the prevention of myopia and reduction of the risk of myopia among school students may be the focus of future research.

目的：本研究旨在探讨户外活动与近视之间关系的现状、热点和新兴研究趋势。

方法：从 Web of Science 核心合集数据库中收集了 2006 年至 2021 年关于户外活动与近视关系的出版物。使用 CiteSpace（版本 6.1.R2）进行文献计量分析，使用 R 软件（版本 4.1.0）对出版物的趋势和热点图进行可视化。

结果：本研究共收集和分析了 640 篇出版物。中国是主要贡献者（ = 204），其次是美国（ = 181）和澳大利亚（ = 137）。美国的国际合作最为广泛（中心度 = 0.25），其次是澳大利亚（中心度 = 0.20）。新加坡国立大学发表的论文数量最多（ = 48），其次是中山大学（ = 41）和澳大利亚国立大学（ = 41）。在机构方面，英国卡迪夫大学的国际合作最为广泛（中心度 = 0.12），其次是新加坡国立大学（中心度 = 0.11）。新加坡的 Saw S 发表的论文数量最多（ = 39），其次是澳大利亚的 Morgan I（ = 27）和德国的 Jonas J（ = 23）。《柳叶刀全球健康》是研究户外活动与近视关系的最重要期刊。Holden BA 发表的“全球近视和高度近视的患病率及 2000 年至 2050 年的时间趋势”一文在该领域被引次数最多，为 177 次。关键词共现和突现分析表明，该领域的研究趋势和热点主要集中在“风险”、“预防”和“学校”。

结论：户外活动对近视的影响仍然令人关注。未来需要国家或机构之间更深入的合作，以探索户外活动对近视的影响。预防近视和降低学生近视风险的户外活动可能是未来研究的重点。
