Objectives: We aimed to assess whether there is an association between the proportion of female editors-in-chief and members of editorial boards in infectious disease (ID) and microbiology journals.

Methods: Our cross-sectional observational study included ID or microbiology journals according to the 2019 Clarivate Journal Citation Reports. Journals' Q ranking, open-access status, and number and gender of editors-in-chief and editorial board members were collected from the journals' official websites. We conducted a binary gender assignment for each editor using names, pictures, and other online descriptors. Journals with over 100 editorial board members and those with over 25% of board members for whom we could not determine gender were excluded. Editorial teams with >50% women were considered women dominant. Univariate and multivariable analyses for female editor dominance were performed.

Results: Overall, 167 journals were included, with total 6057 editorial members, 1655 (27.3%) of whom were women. Of 214 editors-in-chief, 48 (22%) were women, and only 25% (40 of 162) of journals had female editor-in-chief dominance. Factors associated with female dominance in the editor-in-chief role in univariate analysis were higher quartile rank, higher impact factor, and open access. Open-access journals remined significant in multivariable analysis (odds ratio (OR) 2.521; 95% CI, 1.140-5.576, p = 0.022). Larger editorial boards were less likely to have female dominance. Female editor-in-chief dominance was significantly associated with women-dominant editorial boards.

Discussion: ID and microbiology journals have significantly few women as editors-in-chief and editorial board members. Understanding the reasons for this inequality is required as an important step to confront and resolve it.
