AbstractGender authorship trends have been explored in varied medical specialties, and no study had observed in the field of gastric cancer. Therefore, we aimed to access whether the "gender gap" in authorship existed in gastric cancer in the leading gastroenterological journals over the last 2 decades. All original articles published from 2000 to 2020 in 9 leading gastroenterological journals were collected. Information on the first and senior author's gender, country of author's institution, and impact factor of journals were collected. Chi-square tests and multivariable logistic regression were used for data analysis. A total of 5785 original articles were included and analyzed, of which 440 (7.61%) were articles on gastric cancer and 5345 (92.39%) covered other topics. Fewer female authors published original articles as first (19.32%, 85/440) and senior authors (14.32%, 63/440) compared with males. Remarkably, a significant increase in female authorship was discovered. The proportion of female first authors grown from 12.99% to 30.89% during the last 20 years (P < .001), but not in senior authors (P = .175). Multivariable logistic analysis showed that female first authors demonstrated a higher percentage when senior authors were female (odds ratio, 2.040; 95% confidence interval, 1.105-3.769). Although a statistically ascending tendency in female first authors on gastric cancer has been going on over the last 20 years, the exorbitant gender gap still exists. This gap may help explain the continued underrepresentation of women within both clinical work and academic research, and prompt us to look further for the underlying causes.Copyright © 2023 the Author(s).
