Pediatric gastroenterology is a clinical and research discipline principally developed over the past 50 years. Bibliometric methods provide quantitative analysis and identify research trends. Study aims were to characterize the growth and trends in pediatric gastroenterology clinical and translational research using citation analysis.
Using citations analysis software, a search strategy specific for pediatric gastroenterology was implemented for the years 1970 to 2017. The 50 most-cited research articles per decade were identified. These 250 articles were coded for topic and study attribute. Analysis included authors, affiliations, journals, countries, and funding sources.
Overall average annual growth rate for pediatric gastroenterology publications was significantly higher than that for general pediatrics (51.7% vs 6.2%; P < 0.05). Among the top 250 cited articles, the distribution of study focus was epidemiology (43%), pathophysiology (18%), treatment (16%), diagnosis (8%), prevention (8%), and comorbidities of gastrointestinal diseases (7%).There were 38 different topics represented and there was a notable shift in topic focus over time. Cholestasis, biliary atresia, and total parenteral nutrition were common topics from 1970 to 1989 and obesity, nonalcoholic fatty liver disease, and eosinophilic esophagitis were common topics after 1990. Notably, 2.3% of the authors accounted for 30% of the top 250 articles.
Pediatric gastroenterology research has undergone rapid growth yielding advancements in the management of gastrointestinal conditions in children. The emergence of new diseases in need of better diagnostics and therapeutics led to a temporal shift in research focus. Further advancements will require multidisciplinary collaborations and continued funding for pediatric gastroenterology research.
儿科胃肠病学是一个主要在过去 50 年发展起来的临床和研究学科。文献计量学方法提供定量分析并确定研究趋势。本研究旨在通过引文分析来描述儿科胃肠病学临床和转化研究的增长和趋势。
使用引文分析软件，针对 1970 年至 2017 年实施了一项特定于儿科胃肠病学的搜索策略。确定了每个十年的 50 篇最具引用价值的研究文章。对这 250 篇文章进行了主题和研究属性编码。分析包括作者、附属机构、期刊、国家和资金来源。
儿科胃肠病学出版物的年平均增长率明显高于普通儿科（51.7% vs 6.2%；P < 0.05）。在这 250 篇被引用最多的文章中，研究重点的分布为流行病学（43%）、病理生理学（18%）、治疗（16%）、诊断（8%）、预防（8%）和胃肠道疾病的合并症（7%）。共有 38 个不同的主题，主题重点随时间发生了显著变化。1970 年至 1989 年期间，胆汁淤积、胆道闭锁和全胃肠外营养是常见的主题，1990 年后，肥胖、非酒精性脂肪性肝病和嗜酸性食管炎是常见的主题。值得注意的是，2.3%的作者占 250 篇最具影响力文章的 30%。
儿科胃肠病学研究取得了快速发展，在儿童胃肠道疾病的治疗方面取得了进展。新疾病的出现需要更好的诊断和治疗方法，导致研究重点出现了时间上的转移。进一步的进展将需要多学科合作和继续为儿科胃肠病学研究提供资金。
