To assess and compare the scientific pediatric production of Spanish authors in Pubmed and Journal Citation Reports (JCR) between 1996 and 2001.
We reviewed the first 200 articles that appeared in PubMed between 1996 and 2001 on childhood ("newborn OR neonate OR children OR child OR infant") by Spanish authors (Spain [affiliation]). We compared the quality of study design, sample sizes, subject of the article, impact factor and the authors' specialty, using the chi-squared and/or Student's t-test. The factors related to publication in journals with an impact factor of more than 2 were analyzed using logistic regression analysis.
Only 35 % of the articles selected were performed exclusively in children. Between 1996 and 2001, Spanish pediatric publications included in the Journal Impact Factor increased by 37.5 %. The impact factor between these two years was similar (1.776 vs 1.823; p: NS). An impact factor of more than 2 was related to articles published in non-pediatric journals (OR: 3, 95 % CI: 1.17-7.69, p 0.018), publications including multiple regression analysis in the statistical analysis (OR: 3.27; 95 % CI: 1.12-9.56; p 0.028), multicenter studies (OR: 4.2, 95 % CI: 1.1-22.4, p 0.048) and articles on immunology or molecular biology (OR: 2.45; 95 % CI: 1.01-5.92; p 0.044).
In the last 5 years Spanish pediatric publications in journals included in the JCR increased by 37.5 %. We should promote publications with larger sample sizes, multicentric studies and those with high quality design (clinical trials and cohort studies).
评估并比较1996年至2001年间西班牙作者在PubMed和期刊引证报告（JCR）中发表的儿科领域科研成果。
我们检索了1996年至2001年间西班牙作者（所属机构为西班牙）在PubMed上发表的关于儿童期（“新生儿或新生儿期或儿童或儿童期或婴儿”）的前200篇文章。我们使用卡方检验和/或学生t检验比较了研究设计质量、样本量、文章主题、影响因子和作者专业。使用逻辑回归分析对在影响因子大于2的期刊上发表文章的相关因素进行了分析。
所选文章中仅有35%是专门针对儿童进行的研究。1996年至2001年间，被纳入期刊影响因子统计的西班牙儿科出版物增加了37.5%。这两年间的影响因子相似（1.776对1.823；p值：无显著性差异）。影响因子大于2与在非儿科期刊上发表的文章相关（比值比：3，95%置信区间：1.17 - 7.69，p = 0.018），与在统计分析中包含多元回归分析的出版物相关（比值比：3.27；95%置信区间：1.12 - 9.56；p = 0.028），与多中心研究相关（比值比：4.2，95%置信区间：1.1 - 22.4，p = 0.048）以及与免疫学或分子生物学方面的文章相关（比值比：2.45；95%置信区间：1.01 - 5.92；p = 0.044）。
在过去5年中，被JCR收录的期刊上西班牙儿科出版物增加了37.5%。我们应推广样本量更大、多中心研究以及高质量设计（临床试验和队列研究）的出版物。
