Abstract
With the outbreak of the 2019 coronavirus (COVID-19) pandemic, the issue of increasing health disparities has received a great deal of attention from scholars and organizations. This study analyzes 2282 papers on COVID-19-related health disparities that have been retrieved from the WOS database, with 58,413 references. Using bibliometric analysis and knowledge mapping visualizations, the paper focuses on the academic structure and research trends by examining the research distribution of countries, journals and authors, keywords, highly cited articles, and reference co-citation. The results show that the United States has contributed the most, and the International Journal of Environmental Research and Public Health has published the largest number of papers on this topic. As for the core authors, Michael Marmot is the most productive. Issues such as racial health, mental health, and digital health disparities have been the trending topics of the COVID-19-related health disparities. The research directions include the features, factors, and interventions of health disparities under the influence of COVID-19. As such, this study provides literature support and suggestions to investigate COVID-19-related health disparities. The findings of the paper also remind public health regulators to consider factors of health disparities when developing long-term public health regulatory policies related to the pandemic.
Highlights
Health disparities research has attracted widespread attention from scholars and policy makers in public health since the 19th century [1]
We found that these 10 countries generally focused on three areas of health disparities research during the COVID-19 pandemic, namely health care sciences and and services, services, public public environmental environmental occupational occupational health, health, and and infectious infectious diseases
Society and Alzheimer’s & Dementia were at the core. These findings indicate that the papers that were published in these journals made important contributions to the study of health disparities and COVID-19
Summary
Health disparities research has attracted widespread attention from scholars and policy makers in public health since the 19th century [1]. There is no consensus on the definition of health disparities, but all the definitions share a common theme: health differences among groups. A health disparity was defined by Healthy People (2020) as “a particular type of health difference that is closely linked with social, economic, and/or environmental disadvantage”.
