Orthopaedics is the clinical discipline with the lowest percentage of female residents and faculty. Pediatric orthopaedics has a higher percentage of women than other orthopaedic subspecialties. It was the purpose of this study to examine bibliometric trends in the Journal of Pediatric Orthopaedics (JPO) with a specific focus on sex.
A bibliometeric analysis for the years 2015, 2005, 1995, 1985, 1981 was performed. The names of first and corresponding authors; corresponding author position; country of origin; number of institutions, countries, authors, printed pages, and references was tabulated. Author sex was identified for the first and corresponding authors using the "Baby Name Guesser" (www.gpeters.com/names/baby-names.php). A P<0.05 was considered significant.
There were 746 publications; 68.7% were from North America. The average number of authors, corresponding author position, collaborating institutions, countries, and number of references increased, whereas the number of printed pages decreased. Asia had the greatest number of authors (4.4), with Australia/New Zealand the fewest (3.4). Sex was determined for 98.3% of the first authors and 98.5% of the corresponding authors. There was a significant increase in the number of female first authors over time (5.9% to 25.6%, P<10), especially in Europe and North America. There were significant increase in the number of female corresponding authors over time (5.8% to 17.6%, P=0.000009). There was a significant trend to have a greater percentage of both female first and corresponding authors over time (P=0.0005) with a reverse trend for both male first and corresponding authors (P<10).
In this study, we noted that the number of female first and corresponding authors in Journal of Pediatric Orthopaedics has been steadily increasing. This should result in more female pediatric orthopaedic surgeons in academic faculty positions.
骨科是住院医师和教职员工中女性比例最低的临床学科。小儿骨科的女性比例高于其他骨科亚专业。本研究旨在考察《小儿骨科杂志》（JPO）的文献计量学趋势，特别关注性别情况。
对2015年、2005年、1995年、1985年、1981年进行文献计量分析。列出第一作者和通讯作者的姓名、通讯作者职位、原籍国、机构数量、国家数量、作者数量、印刷页数和参考文献数量。使用“婴儿名字猜测器”（www.gpeters.com/names/baby-names.php）确定第一作者和通讯作者的性别。P<0.05被认为具有统计学意义。
共有746篇出版物；68.7%来自北美。作者平均数量、通讯作者职位、合作机构数量、国家数量和参考文献数量增加，而印刷页数减少。亚洲的作者数量最多（4.4人），澳大利亚/新西兰最少（3.4人）。98.3%的第一作者和98.5%的通讯作者的性别得以确定。随着时间推移，女性第一作者数量显著增加（从5.9%增至25.6%，P<0.001），尤其是在欧洲和北美。女性通讯作者数量也随时间显著增加（从5.8%增至17.6%，P = 0.000009）。随着时间推移，女性第一作者和通讯作者的比例均有显著增加趋势（P = 0.0005），而男性第一作者和通讯作者则呈相反趋势（P<0.001）。
在本研究中我们注意到，《小儿骨科杂志》中女性第一作者和通讯作者的数量一直在稳步增加。这将使更多女性小儿骨科外科医生担任学术教职。
