By providing a picture from published articles in a field, bibliometric studies can inform policy-makers in their challenging research funding decisions. In this regard, we applied bibliometric analysis to the Iranian pediatrics articles published in PubMed indexed journals between 1975 and 2007.
We evaluated all pediatric articles that had been published from Iran in different PubMed indexed journals from 1975 to 2007. Journal data (i.e. date of publishing, journal name, impact factor of the journal, language), authors data (i.e. number of authors, international collaboration, affiliation of the corresponding author), and paper characteristics [i.e. type of article, research design, study population (neonate, infant, child, and adolescent), and specialty] were registered.
During this period of time, 819 articles from Iran had been published in PubMed indexed journals, with a sharp increasing trend after 2002. Impact factors were up to 25.8. Paper had an international co-author in 13.7%. Regarding study population, 24.1% of studies were published on neonates, 23.6% on infants, and the remaining 66.3% of studies were performed on children and adolescents from 2 to 18 years old. Infectious disease was the most frequent area of research, followed by public health and metabolic disease. Original articles were the most frequent type (89.7%) of the published articles. Study design was cross-sectional in 51.2%, retrospective in 36.3%, and prospective in 11.6%. Clinical trials made up 4.8% of the total papers.
Contribution of Iran in production of pediatrics science is showing a sharp increase after 2002, this pattern is in parallel with other research fields.
通过呈现某一领域已发表文章的情况，文献计量学研究可为政策制定者做出具有挑战性的研究资金决策提供参考。在此方面，我们对1975年至2007年间发表于被PubMed收录期刊上的伊朗儿科学术文章进行了文献计量分析。
我们评估了1975年至2007年间伊朗在不同被PubMed收录期刊上发表的所有儿科学术文章。记录了期刊数据（即发表日期、期刊名称、期刊影响因子、语言）、作者数据（即作者数量、国际合作情况、通讯作者单位）以及论文特征[即文章类型、研究设计、研究人群（新生儿、婴儿、儿童和青少年）和专业领域]。
在此期间，伊朗有819篇文章发表于被PubMed收录的期刊上，2002年后呈急剧上升趋势。影响因子高达25.8。13.7%的论文有国际合著者。关于研究人群，24.1%的研究是针对新生儿，23.6%针对婴儿，其余66.3%的研究是针对2至18岁的儿童和青少年。传染病是最常见的研究领域，其次是公共卫生和代谢疾病。原创文章是发表文章中最常见的类型（89.7%）。研究设计中横断面研究占51.2%，回顾性研究占36.3%，前瞻性研究占11.6%。临床试验占论文总数的4.8%。
2002年后伊朗在儿科学术成果方面的贡献呈急剧上升趋势，这一模式与其他研究领域相似。
