    Underrepresentation of females in surgery is reflected in research productivity across academic medicine, with male faculty being more likely to publish research than their female counterparts. In this study, we aimed to describe the representation and longevity of female investigators among the authors of articles in 3 foot and ankle research journals from 1993 to 2017. In this retrospective bibliometric analysis, authors from 3 prominent foot and ankle research journals (Foot and Ankle International, The Journal of Foot and Ankle Surgery, and Foot and Ankle Clinics) were identified. The proportion of female authors who were first, middle, and senior authors and the total publication count per author were determined. From 1993 to 2017, 8132 original articles were published and a total of 6597 (81.1%) had an accessible author list. This allowed us to identify 25,329 total authors, of whom 22,961 (90.7%) were successfully matched to a gender. A total of 9273 unique authors were identified (females, 19.2%). Female representation increased for first and senior authors over the years from 6.5% and 5.9% (1993 to 1997) to 16.9% and 13.1% (2013 to 2017, p < .001), respectively. However, compared with male authors, female authors published fewer articles (mean: 1.7 versus 2.4, p < .001). Of the 2691 authors who first published during 2006 to 2011, 369 authors (13%), consisting of 8.1% females and 15% males (p < .001), continued to publish 5 years after their initial publication. Female representation in academic foot and ankle research has increased >2-fold over the past 2 decades. But despite these advances, compared to male authors, female authors are less likely to continue publishing 5 years after initial publication, and on average publish fewer articles. © 2019 the American College of Foot and Ankle Surgeons

    Background Context Despite recent advances in gender equity in medicine, the representation of women in orthopedic and neurosurgery remains particularly low. Furthermore, compared with their male colleagues, female faculty members are less likely to publish research, limiting opportunities in the academic promotion process. Understanding disparities in research productivity provides insight into the “gender gap” in the spine surgeon workforce. Purpose This study aims to determine the representation and longevity of female physician-investigators among the authors of five spine-related research journals from 1978 to 2016. Study Design This is a retrospective bibliometric review. Methods The authors of original research articles from five prominent spine-related journals (European Spine Journal, The Spine Journal, Spine, Journal of Spinal Disorders and Techniques, and Journal of Neurosurgery: Spine) were extracted from PubMed. For authors with a complete first name listed, gender was determined by matching first name using an online database containing 216,286 distinct names across 79 countries and 89 languages. The proportion of female first and senior authors was determined during the time periods 1978 to 1994, 1995 to 1999, 2000 to 2004, 2005 to 2009, and 2010 to 2016. The authors who had their first paper published between 2000 and 2009 were included in additional analyses for publication count and longevity (whether additional articles were published 5 years after first publication). Student t test, chi-square analysis, and Cochran-Armitage trend test were used to determine significance between groups. Results From 1978 to 2016, 28,882 original research articles were published in the five spine-related journals. A total of 24,334 abstracts (90.9%) had first names listed, identifying 120,723 authors, in total of which 100,286 were successfully matched to a gender. A total of 33,480 unique authors were identified (female authors: 31.8%). Female representation increased for first and senior authors from 6.5% and 4.7% (1978–1994) to 18.5% and 13.6% (2010–2016, p<.001). Growth in female senior author representation declined after 2000 (12.3% vs. 12.9% vs. 13.5% between 2000–2004, 2005–2009, and 2010–2016). Compared with male authors, on average, female authors published fewer articles (mean: 2.1 vs. 3.3, p<.001). Of 15,304 authors who first published during 2000 to 2009, 3,478 authors (22.7%) continued to publish 5 years after their first publication. Female authors were less likely to continue publishing after their first article (15.3% of female authors vs. 24.8%, p<.001). Conclusions Female representation in academic spine research has doubled over the past 4 decades, although the growth of female representation as senior author has plateaued. Female physician-investigators are half as likely to continue participating in spine-related research longer than 5 years and on average publish half as many articles as senior author. In addition to recruiting more women into research, efforts should be made to identify and address barriers in research advancement and promotion for female physician-investigators. © 2017 Elsevier Inc.
