Low Prevalence of Reporting of Participant Race and Ethnicity in Gastroenterology Research Publications.

Introduction: Empirical information on the evolution of reporting race and ethnicity information in gastroenterology research is lacking. To facilitate understanding of where improvements are needed to increase diversity, equity, and inclusion in gastroenterology research, we aimed to evaluate reporting and representation by race and ethnicity in studies published in flagship US-based gastroenterology journals over 20 years.

Methods: We manually reviewed reporting and representation by race and ethnicity in all original research articles published in the American Journal of Gastroenterology and Gastroenterology in 2000, 2010, and 2020.

Results: Of 1,168 publications, 24% reported information on race/ethnicity, significantly more commonly reported in US-based study samples vs non-US-based samples. While reporting significantly increased over time, reporting rates were still low as of 2020 (37% overall; 54% with US-based samples).

Discussion: We recommend that gastroenterology journals create standard reporting requirements for sociodemographic information, including information on race, ethnicity, and/or cultural background.
