Gender disparity is pervasive in academic medicine. This study aimed to assess the disparity between men and women with regard to first and senior author positions in primary studies on liver cancer over the last two decades.
We conducted a review of articles published in high-impact factor journals of the field of Gastroenterology and Hepatology in 2005, 2010, 2015 and 2020. First and senior authors of all ages were considered as the study population. The authors' genders were determined using the online artificial intelligence tool genderize.io (https://genderize.io/). The disparity between men and women authors was assessed using the linear-by-linear association test.
665 original articles from 10 journals were reviewed. The point prevalence of first women authors was 25.0% compared with 75.0% for men. The point prevalence of senior women authors was 16.3% compared with 83.7% for men. From 2000 to 2020, the proportion of first women authors increased 14.4% to 26.8% compared with 85.6%-73.2% for men (P = 0.009), and the proportion of senior women authors increased from 7.4% to 19.5%, compared with 92.6%-80.5% for men (P = 0.035). The factor independently associated with a reduced representation of women among first authors was the region of author. The factor independently associated with a reduced representation of women among senior authors was the impact factor of journals.
The findings indicated a remarkable increase in the proportion of women, both first and senior authors, over the past two decades in the field of liver cancers. However, the representation of women authors in this area is far less than that of men.
学术医学领域普遍存在性别差异。本研究旨在评估过去二十年中肝癌基础研究中第一作者和资深作者职位的男女差异。
我们对胃肠病学和肝脏病学领域高影响力期刊 2005 年、2010 年、2015 年和 2020 年发表的文章进行了回顾。所有年龄段的第一作者和资深作者均被视为研究人群。使用在线人工智能工具 genderize.io（https://genderize.io/）确定作者的性别。使用线性-线性关联检验评估男女作者之间的差异。
共审查了来自 10 种期刊的 665 篇原始文章。女性第一作者的现患率为 25.0%，而男性为 75.0%。女性资深作者的现患率为 16.3%，而男性为 83.7%。从 2000 年到 2020 年，女性第一作者的比例从 14.4%增加到 26.8%，而男性的比例从 85.6%下降到 73.2%（P=0.009），女性资深作者的比例从 7.4%增加到 19.5%，而男性的比例从 92.6%下降到 80.5%（P=0.035）。与第一作者中女性代表性降低相关的独立因素是作者所在地区。与资深作者中女性代表性降低相关的独立因素是期刊的影响因子。
研究结果表明，在过去的二十年中，该领域女性第一作者和资深作者的比例都显著增加。然而，女性作者在该领域的代表性仍然远远低于男性。
