Gender disparities remain in the field of gastroenterology (GI) despite the decreasing gender gap in the medical field overall. We sought to examine primary and last female authorship as a marker of academic opportunity and advancement to assess the proportion of women publishing in GI over 20 years (1997-2017).In this observational study, we assessed the gender and nationality of primary and last authors of original research manuscripts in three GI journals (Gastroenterology, Gut, and American Journal of Gastroenterology) across a 20-year period in 5-year intervals (in 1997, 2002, 2007, and 2012). We used a validated gender-determining algorithm, genderize.io, to classify gender. Our primary outcome was the proportion of female primary and last authors, with secondary measures assessing trends in gender and nationality.Through the Genderize.io gender database, we were able to identify the gender for 3,673 (95.9%) of primary author names and 3,504 (95.4%) of last author names in the 3,615 manuscripts evaluated. Overall, there was a significant increase in female primary authors over time, from 18.1% in 1997 to 42.6% in 2017, a 6.0% increase per 5-year period (95% CI 4.8-7.2%). A similar trend was found for female last authors, however, at a slower rate, from 8.3% in 1997 to 24.7% in 2017, a 3.5% increase per 5 years (95% CI 2.5-4.4%). These trends were noted cumulatively, and in each journal individually. Manuscripts with a female last author were more likely to demonstrate a female primary author.Female authorship in high-impact gastroenterology journals has increased over time. Last authorship has lagged primary authorship in female representation and has increased more slowly over time. Interventions to reduce gender disparity in GI research should focus on the transition from first to last authorship. |
