Journal of Racial and Ethnic Health Disparities

Publication in leading medical journals is critical to knowledge dissemination and academic advancement alike. Leveraging a novel dataset comprised of nearly all articles published in JAMA and NEJM from 1990 to 2020, along with established reference works for name identification, we explore changing authorship demographics in two of the world's leading medical journals. Our main outcomes are the annual proportion of male and female authors and the proportion of racial/ethnic identities in junior and senior authorship positions for articles published in JAMA and NEJM since 1990. We found that women remain under-represented in research authorship in both JAMA (at its peak, 38.1% of articles had a female first author in 2011) and NEJM (peaking at 28.2% in 2002). The rate of increase is so slow that it will take more than a century for both journals to reach gender parity. Black and Hispanic researchers have likewise remained under-represented as first and last authors in both journals, even using the best-case scenario. Their appearance as authors has remained stagnant for three decades, despite attention to structural inequalities in medical academia. Thus, analysis of authorship demographics in JAMA and NEJM over the past three decades reveals the existence of inequalities in high-impact medical journal authorship. Gender and racial/ethnic disparities in authorship may both reflect and further contribute to disparities in academic advancement.
