Geographic and Gender Representation in Authors of Editorials on Publications from Low- and Middle-Income Countries

The selection of authors for editorials reflects perceptions of expertise and influence. Our objectives were to determine author geographic and gender distribution, determine temporal trends in editorial authorship, and identify factors associated with the inclusion of authors affiliated with low- and middle-income countries (LMICs) in editorials on research conducted in LMICs. We conducted a cross-sectional study of editorials on research in LMICs published in 15 global health, pediatrics, and general medicine journals from 2014 to 2024. To assess temporal changes in authorship, we plotted the proportion of editorial authors affiliated with LMICs and those with female names by year. We used multivariable logistic regression to identify factors associated with the inclusion of one or more LMIC-affiliated authors. There were 107,629 publications and 1,350 editorials on research in LMICs with 2,401 authors. Authors of editorials were most often affiliated with institutions in North America (38.1%) and high-income countries (71.6%). The proportion of authors of editorials affiliated with institutions in high-income countries decreased from 84.9% in 2014 to 65.3% in 2024. Authors of editorials more commonly had male names than female (60.1% versus 38.7%, P <0.001). The proportion of editorial authors with female names increased from 32.1% in 2014 to 48.2% in 2024. Editorials accompanying publications reporting studies with larger sample sizes (aOR = 1.52, 95% CI: 1.03-2.26) and research conducted in sub-Saharan Africa (aOR = 2.84, 95% CI: 1.74-4.68) were more likely to include LMIC-affiliated authors. Additional efforts are needed to include authors affiliated with LMICs in editorials on research conducted in LMICs.
