This descriptive cross-sectional study examined the proportion of women, men, and non-binary gender experts quoted in major American newspapers in publicly-available articles referring to the SARS-CoV-2 pandemic. Institutional ethics board approval was not applicable given the study design. This manuscript is reported according to the Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) guidelines7 and the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines when describing the systematic search strategy used to identify articles.
Factiva and the US Major Dailies databases were used to identify newspaper articles for inclusion. The full search strategy for each database was developed after consultation with a librarian and is available in Appendix 1 and 2. Newspaper articles were eligible if they were published between April 1st, 2020 and April 15th, 2020 in the English language, contained the words "COVID-19" or "coronavirus", and were found in the print version of one of the top ten most widely read newspapers in the United States (USA Today, Wall Street Journal, New York Times, New York Post, Los Angeles Times, Washington Post, Star Tribune, Newsday, Chicago Tribune, and the Boston Globe).8 Online-only content, letters to the editor, advice columns, article corrections, and obituaries were excluded.
Each newspaper article was reviewed by one study team member to identify eligible expert sources. Reviewers used a standardized data extraction form that was pilot tested by all members of the study team (Appendix 3). Twenty randomly selected articles were reviewed by two study members to determine the Cohen's kappa of data extraction. The date of publication, article title, reporter(s), expert name, expert gender as determined by pronouns used within the article, expert gender as identified by another source, and expert title or position were extracted. Further, members of our research team contacted each newspaper editor a minimum of two times to determine if the newspaper had a policy on inclusion or gender related to expert sources.
All people mentioned in the text of the article were considered for inclusion as an expert source. To be included in our analysis, an expert source (1) had to be cited as an expert on health, health systems, or disease; (2) had to speak about SARS-CoV-2, COVID-19, or coronavirus disease; and (3) had to speak about human impacts or human disease (Table 1). People were not included as an expert if they were mentioned only to recount or describe events rather than provide information as an expert. In addition, people were not included as an expert if they were referenced only as a spokesperson for an agency or organization. We excluded anonymous and unnamed sources. When a reviewer was unsure whether to include a potential expert, another member of the study team also reviewed the article and both reviewers had to agree to include the expert.
Expert gender was assigned based on pronoun usage within the text article (he/him corresponded to a man expert, she/her corresponded to a woman expert, and other pronouns such as they/them or ze corresponded to a non-binary gender expert). If the expert's pronouns were not available in the article text, the expert's name and title were used to search the internet for a university, hospital, or business website to determine the expert's gender. If an expert was mentioned in another newspaper article, the pronouns from that article could be used to assign gender. An expert's gender was categorized as unknown if there were no pronouns or gender listed within the newspaper article or on an official university, hospital, or business website for the expert. An expert was included for each article that they were cited in, but an expert was included only once per newspaper article, even if cited multiple times within the article.
We report the total number of experts and number of unique experts mentioned in newspaper articles who were men, women, or another gender with 95% confidence intervals (CI). We did not compare the proportion of men and women experts statistically because there was no established baseline of potential men and women experts.
