    Background: Alzheimer's disease and dementia are an increasing burden affecting more than 50 million patients worldwide. Hence, research has increased significantly in recent decades. It is recognized that female authors are systematically underrepresented in research in general. Objective: In this article, we examine gender disparities in academic research on dementia and Alzheimer's disease in the last decade. Methods: 104,858 male and female authorships from 37,961 original research articles were analyzed. The global and country-specific distribution of women across first, co, and last authorships was determined with the inclusion of a citation and productivity analysis. Results: 42.1% of all authorships and 50.2% of the first, 42.2% of the co, and 32.8% of the last authorships were held by women. Women were less commonly cited, published fewer articles and were also less likely to secure prestigious authorships in articles with multiple authors compared with men. Distinct differences were observed among the countries. Conclusion: Substantial growth in the number of prestigious female authorships has been observed to date and is predicted to continue in the future, with an emphasis on the progressive representation of women and a diminishing gender gap. © 2019 - IOS Press and the authors.

    Objective: The study aims to elucidate the state of gender equality in epilepsy research, analyzing the representation of female authorships from 2008 to 2016. Methods: Gendermetrics aided in analyzing 106,282 authorships from 22,180 epilepsy-related original research articles. The key methodology was the combined analysis of the relative frequency and the odds ratio of female authorships. The Prestige Index measures the distribution of prestigious authorships between the two genders. Results: The following were held by women: 39.6% of all authorships and 44.1% of the first, 41.0% of the co-, and 29.0% of the last authorships. Female authors have an odds ratio of 1.25 (95% CI 1.21–1.29) for first, 1.17 (CI 1.14–1.20) for co-, and 0.57 (CI 0.55–0.59) for last authorships. The female authorship ratios showed substantial growth in recent years, with an annual growth rate of 1.7% overall, with 2.4% for first, 1.4% for co-, and 1.9% for last authorships. Women publish fewer articles compared to men (43.8% female authors hold 39.6% of the authorships). Women are also less likely to secure prestigious authorships in articles with many authors that attract the highest citation rates. Multi-author articles with male key authors are cited slightly more frequently than articles with female key authors. Distinct differences at the country level were revealed. The prognosis for the next decade forecasts significantly increasing female odds for first authorships and only slightly higher female odds for last authorships. A female authorship ratio of 49.2% is predicted for the year 2026. Significance: The integration of women in the scientific field of epilepsy is advanced. However, a dichotomy is present: Although the current system promotes early career steps, there is an apparent lack of female research leaders. This structural imbalance is expected to grow in the next decade due to the consistently high increase of female early career researchers.

    Background The present study aims to elucidate the state of gender equality in high-quality research by analyzing the representation of female authorships in the last decade (from 2008 to 2016). Methods Based on the Gendermetrics platform, 293,557 research articles from 54 journals listed in the Nature Index were considered covering the categories Life Science, Multidisciplinary, Earth & Environmental and Chemistry. The core method was the combined analysis of the proportion of female authorships and the female-to-male odds ratio for first, co- and last authorships. The distribution of prestigious authorships was measured by the Prestige Index. Results 29.8% of all authorships and 33.1% of the first, 31.8% of the co- and 18.1% of the last authorships were held by women. The corresponding female-to-male odds ratio is 1.19 (CI: 1.18–1.20) for first, 1.35 (CI: 1.34–1.36) for co- and 0.47 (CI: 0.46–0.48) for last authorships. Women are underrepresented at prestigious authorships compared to men (Prestige Index = -0.42). The underrepresentation accentuates in highly competitive articles attracting the highest citation rates, namely, articles with many authors and articles that were published in highest-impact journals. More specifically, a large negative correlation between the 5-Year-Impact-Factor of a journal and the female representation at prestigious authorships was revealed (r(52) = -.63, P < .001). Women publish fewer articles compared to men (39.0% female authors are responsible for 29.8% of all authorships) and are underrepresented at productivity levels of more than 2 articles per author. Articles with female key authors are less frequently cited than articles with male key authors. The gender-specific differences in citation rates increase the more authors contribute to an article. Distinct differences at the journal, journal category, continent and country level were revealed. The prognosis for the next decades forecast a very slow harmonization of authorships odds between the two genders. © 2018 Bendels et al.
