Research hotspots and trend analysis of myopia in children and adolescents based on Chinese databases

Abstract

Objective To analyze research hot spots and trends on myopia in children and adolescents in China, and to providea reference for the future development of this research field.

Methods Using CiteSpace software, 725 eligible Chinese documentspublished over a 22-year period were sourced from CNKI, VIP and Wanlang Chinese databases, were analyzed during 2000–2021. The data were visualized by a keyword co-occurrence map, and clustering, as well as burst and author cooperative networks.

Results The research field of myopia in children and adolescents in China had undergone three stages: an initial formation period, development period and rapid growth period, and it was expected that the annual number of papers will maintain an increasing trendin the future. “Myopia” “adolescents” “children” and “students” were the most frequent keywords (667, 535, 288, 47). The keyword burst “adolescents” started the earliest, and “students” had the largest burst strength and duration. Zhang Ning, Tang Wenting, Tao Fangbiao, Yang Xiao and others have made important contributions to this research field.

Conclusion In recent years, the research focus in this field has gradually shifted toward the influencing factors, as well as prevention and treatment measures ofchild and adolescent myopia. The trend of myopia in young children and adolescents is obvious. In the future, research on the prevention, control and treatment of myopia in children and adolescents will become a hot spot.

Abstract

【摘要】 目的 对中国儿童青少年近视研究领域的热点和趋势进行分析, 并对未来发展进行展望, 为后续研究提供参考依据。 方法 利用CiteSpace软件, 对中国知网、维普、万方中文数据库中 2000—2021 年的 725 篇有效中文文献进行关键词共现、聚类、爆发, 作者合作网络分析, 并制作可视化图谱。 结果 中国儿童青少年近视研究领域经历了初步形成期-发展期-快速增长期 3 个阶段, 预计未来的年发文量仍将保持增长趋势; “近视” “青少年” “儿童” “学生” 是频率最髙的关键词(频次分别为 667, 535, 288, 47); 关键词 “青少年” 爆发开始时间最早, “学生” 爆发强度最大, 持续时间最长; 张宁、唐文婷、陶芳标、杨晓等为该领域的研究做出重要贡献。 结论 近年来儿童青少年近视领域研究重点逐渐向近视的影响因素及预防治疗措施转移, 儿童青少年近视低龄化趋势明显, 未来针对近视防控与治疗手段的研究将会成为热点。
