Research on migrants has grown significantly over the past 20 years. However, systematic reviews and summaries of the health equity of migrants are lacking.
This bibliometric analysis aims to reveal the knowledge structure, cooperation networks, and research frontiers in immigrant health equity for the first time, providing a framework and guidance for future studies.
Publications related to health equity of migrants from 1993 to 2024 were collected from Scopus. The publications collected were restricted to certain categories (articles and reviews). VOSviewer and Citaspace were used to analyze the country/region, institution, research topic, keyword co-occurrence, and highly cited papers.
Four hundred nine articles were included in this study. It was found that the field entered a period of rapid growth after 2013, with an average of 29.67 articles per year, and the research enthusiasm has continued to rise. Articles originated from 63 countries/regions and 160 institutions. The study found that in terms of international cooperation and output, the United States (US) (55.74%), Canada, the United Kingdom, and China are the main research forces, with the University of California, San Francisco ranking first in the number of published papers; the US-United Kingdom, US-Canada, and US-China have formed the strongest cooperation networks. This study also reveals its interdisciplinary research characteristics, covering multiple fields such as medicine (75.31%) and social sciences (23.72%), and forms 5 core research clusters: healthcare services and social determinants: focusing on the impact of healthcare resource accessibility and socioeconomic status on health equity; demographic differences: paying attention to health inequalities caused by factors such as age, gender, and race; family income and Asian health: revealing for the first time the unique impact of family income on the health of Asian immigrants. Highly cited literatures highlight political factors (such as policy discrimination), group inequalities (such as the "Latino health paradox"), and methodological differences as academic focus, providing a theoretical basis for policy-making.
The study confirms international and interdisciplinary trends. Future research should deepen multidisciplinary collaboration, explore group difference mechanisms, evaluate policies, strengthen international cooperation, use diverse methods, and support global immigrant health policy optimization.
在过去20年里，对移民的研究显著增加。然而，缺乏对移民健康公平性的系统综述和总结。
这项文献计量分析旨在首次揭示移民健康公平性的知识结构、合作网络和研究前沿，为未来研究提供框架和指导。
从Scopus数据库收集1993年至2024年与移民健康公平性相关的出版物。收集的出版物限于特定类别（文章和综述）。使用VOSviewer和Citaspace分析国家/地区、机构、研究主题、关键词共现情况以及高被引论文。
本研究纳入了409篇文章。发现该领域在2013年后进入快速增长期，年均发文量为29.67篇，研究热度持续上升。文章来自63个国家/地区和160个机构。研究发现，在国际合作和产出方面，美国（55.74%）、加拿大、英国和中国是主要研究力量，其中美国加州大学旧金山分校发文量居首；美英、美加、美中形成了最强合作网络。本研究还揭示了其跨学科研究特征，涵盖医学（75.31%）和社会科学（23.72%）等多个领域，并形成了5个核心研究集群：医疗服务与社会决定因素：关注医疗资源可及性和社会经济地位对健康公平性的影响；人口差异：关注年龄、性别和种族等因素导致的健康不平等；家庭收入与亚洲健康：首次揭示家庭收入对亚洲移民健康的独特影响。高被引文献突出政治因素（如政策歧视）、群体不平等（如“拉丁裔健康悖论”）和方法差异作为学术重点，为政策制定提供理论依据。
该研究证实了国际和跨学科趋势。未来研究应深化多学科合作，探索群体差异机制，评估政策，加强国际合作，采用多样化方法，支持全球移民健康政策优化。
