Knowledge mapping and research trends of the social determinants of health (SDoH): a scientometric analysis

Abstract Social determinants of health (SDoH) play an essential role in the risk of developing diseases or medical disorders. Conducting a comprehensive retrospective analysis is necessary to better understand the development status, research hotspots, and development trends of SDoH research. The bibliometric analysis method is applied based on CiteSpace and VOS viewer to quantitatively analyze and visually review the articles published in the field of SDoH from Web of Science core databases from 2000 to 2021. We quantitatively analyzed the author, institution, and other basic information to probe the development of SDoH and then visually investigated the high-frequency keywords, burst keywords, and keyword clusters to understand better the evolution of hotspots and development directions of SDoH during the study period. Health inequality is the main keyword of the SDoH field, and disease burden is expected to maintain a hotspot in recent years. Further, research methodologies could be improved to explain how upstream SDoH influences human lived experience. Additionally, the SDoH field needs to utilize the horizons of the multidisciplinary approach to consider and discuss sustainable development issues to offer implications for health improvement policy and interventions.
