Purpose: Low- to middle-income nations contain more than 80% of the world's population; however, only 4% of articles in ophthalmology journals belong to these countries. We aim to analyze the global diversity of the editorial boards of ophthalmology journals.
Methods: Cross-sectional study, including all journals in the Ophthalmology section of the SCImago Journal & Country Rank (SJR). Journals were classified according to the country of origin, SJR interquartile range (Q1-Q4), impact factor, and open-access policy. Global diversity among journals was determined by the country of affiliation of editors-in-chief and editorial board members. Nations were classified by income according to the World Bank's 2022 system. The association between editorial diversity and the journal's metrics and country of origin was analyzed using the χ2 test and the Mann-Whitney U test.
Results: A total of 116 journals were included and 83.6% belonged to high-income nations. Only 18 (13.3%) editors-in-chief and 582 (13.5%) board members were affiliated with middle-income nations. The most prevalent middle-income countries in editorial boards were Brazil (n = 184, 4.26%), India (n = 150, 3.47%), Turkey (n = 42, 0.97%), and Iran (n = 36, 0.83%). Only 40 (1.07%) editorial board members of Q1 journals were affiliated with non-high-income nations, most belonging to India (n = 28, 70%). Journals from middle-income nations had a statistically significant lower prevalence in the first- and second-quartile ranking (P < 0.001) and a higher proportion of open-access policies (P = 0.019).
Conclusions: A clear underrepresentation of low- to middle-income nations was observed in ophthalmology journals. Promoting editorial diversity and minimizing the possibility of editorial bias could lead to greater exposure to real-world data from resource-constrained settings.
Translational relevance: The documented underrepresentation of low- to middle-income nations in ophthalmology journals highlights the importance of promoting diversity and inclusion.
