What is considered as global health scholarship? A meta-knowledge analysis of global health journals and definitions

Despite the rapid growth of the global health field over the past few decades, consensus on what qualifies as global health scholarship or practice remains elusive. We conducted a meta-knowledge analysis of the titles and abstracts of articles published in 25 journals labelled as global health journals between 2001 and 2019. We identified the major topics in these journals by creating clusters based on terms co-occurrence over time. We also conducted a review of global health definitions during the same period. The analysis included 16 413 articles. The number of journals, labelled as global health, and articles published in these journals, increased dramatically during the study period. The majority of global health publications focused on topics prevalent in low-resource settings. Governance, infectious diseases, and maternal and child health were major topics throughout the analysis period. Surveillance and disease outcomes appeared during the 2006-2010 epoch and continued, with increasing complexity, until the 2016-2019 epoch. Malaria, sexual and reproductive health, and research methodology appeared for only one epoch as major topics. We included 11 relevant definitions in this analysis. Definitions of global health were not aligned with the major topics identified in the analysis of articles published in global health journals. These results highlight a lack of alignment between what is published as global health scholarship and global health definitions, which often advocate taking a global perspective to population health. Our analysis suggests that global health has not truly moved beyond its predecessor, international health. There is a need to define the parameters of the discipline and investigate the disconnect between what is published in global health versus how the field is defined.
