Trends in the proportion of women speakers at North American Allergy and Immunology conferences, 2008 to 2020

Background: Women in medicine continue to be underrepresented at medical conferences. Previous studies have evaluated the proportion of invited female speakers across multiple specialties and evaluated factors that may have led to this disparity. The field of Allergy and Immunology has often been excluded and analyses have not illustrated how the trends have changed over the past decade.Objective: To evaluate the distribution of invited speakers by gender over time at the 3 largest North American Allergy and Immunology conferences.Methods: This retrospective longitudinal analysis used conference programs from 2008 to 2020 from the Ameri-can Academy of Allergy, Asthma, and Immunology (AAAAI), the American College of Allergy, Asthma, and Immu-nology (ACAAI), and the Canadian Society of Allergy and Clinical Immunology (CSACI). The gender (binary definition, man or woman, based on names, photos, pronouns, from conference programs and institutional pro-files) of invited speakers was analyzed as the primary outcome, and planning committee members, and multi-speaker sessions as secondary outcomes. These data were compared with publicly available data on the composition of the specialty by gender in the United States and Canada.Results: Women speakers at AAAAI, ACAAI, and CSACI conferences have historically been lower than male speakers and underrepresented compared with specialty composition. However, there has been a significant increase in the proportion of women speakers over time for all 3 conferences individually (AAAAI: 23.7% in 2008, 41.1% by 2020; ACAAI: 16.7% in 2008, 37.3% by 2020; CSACI: 19.4% in 2008, 54.8% by 2020; P < .001 for each) and combined (21.3% in 2008, 40.7% by 2020, P < .001). This trend coincides with a significant increase in women on the planning committee (all conferences: 20% in 2008, 50.6% by 2020; P < .001). There is also a decreasing trend over time for men-only multispeaker sessions.Conclusion: This study sheds light on the trends of women speaker representation at Allergy and Immunology conferences and provides clarity on future needs to reach equal representation in this field.Crown Copyright (c) 2023.
