Cross-sectional study of the relationship between women's representation among editors and peer reviewers in journals of the British Medical Journal Publishing Group.

OBJECTIVES

To investigate whether there is an association between women's representation as peer reviewers and editors of medical journals.

METHODS

In this cross-sectional study, the gender of editors and peer reviewers of journals of the British Medical Journal Publishing Group (BMJ-PG) in 2020 was determined based on given names. Trends over time were analysed for the between 2009 and 2017.

RESULTS

Overall, this study included 47 of the 74 journals in the BMJ-PG. Women accounted for 30.2% of the 42 539 peer reviewers, with marked variation from 8% to 50%. Women represented 33.4% of the 555 editors, including 19.2% of the 52 editors-in-chief. There was a moderate positive correlation between the percentage of women as editors and as reviewers (Spearman correlation coefficient 0.590; p<0.0001). The percentage of women as editors, excluding editors-in-chief, was higher when the editor-in-chief was a woman than a man (53.3% vs 29.2%, respectively; p<0.0001). Likewise, the percentage of women as peer reviewers was higher in journals that had a woman as editor-in-chief in comparison with a man (32.0% vs 26.4%, respectively; p<0.0001). There was a slight increase in the percentage of women as peer reviewers from 27.3% in 2009 to 29.7% in 2017 in the .

CONCLUSIONS

Women account for less than one in three peer reviewers of medical journals. Women's representation as peer reviewers is higher in journals with higher percentage of women as editors or with a woman as editor-in-chief. It is, thus, imperative to address the persisting gender gap at all levels of the publishing system.
