To evaluate the contribution of different world regions in respiratory research productivity.
The world was divided into nine regions based on a combination of geographic, economic, and scientific criteria. Using the PubMed database, we retrieved information about the origin of articles from 30 journals included in the Respiratory System category of the Journal Citation Reports database for a 9-year period (1995 to 2003). We estimated the total number of publications, their mean impact factor, the product of these two parameters, and the research productivity per million of population of the world area divided by the gross national income per capita (GNIPC), for every year and the whole period of the study, for all defined world regions.
Data on the country of origin of the publications was available for 48,614 of 49,382 retrieved articles (98.5%). The majority of articles published between 1995 and 2003 originated from Western Europe (40.4%) and the United States (35.4%). The research productivity compared to population and the GNIPC was found to be higher for Canada and Oceania compared to the United States and Western Europe. The rate of increase of the total published research product (number of published articles multiplied by the impact factor) was higher in the United States and Europe. The total research contribution of Asia, Eastern Europe, Central and Latin America, and Africa regarding the number of published articles was notably very low (approximately 8%).
The data suggest that there was a significant research activity in the field of respiratory medicine during the studied period. Although leaders of production of respiratory medicine research were from Western Europe and the United States, Canada, and Oceania had the best performance after adjustment for population and GNIPC.
评估不同世界区域对呼吸研究生产力的贡献。
根据地理、经济和科学标准的组合，将世界划分为九个区域。利用PubMed数据库，我们检索了《期刊引证报告》数据库呼吸系统类别中30种期刊在9年期间（1995年至2003年）文章的来源信息。我们估算了所有定义的世界区域每年以及整个研究期间的出版物总数、平均影响因子、这两个参数的乘积，以及世界区域每百万人口的研究生产力除以人均国民总收入（GNIPC）。
在检索到的49382篇文章中，有48614篇（98.5%）提供了出版物来源国的数据。1995年至2003年发表的文章大多来自西欧（40.4%）和美国（35.4%）。与美国和西欧相比，加拿大和大洋洲的研究生产力与人口和GNIPC的比较更高。美国和欧洲已发表研究成果总量（发表文章数量乘以影响因子）的增长率更高。亚洲、东欧、中美洲和拉丁美洲以及非洲在发表文章数量方面的总研究贡献非常低（约8%）。
数据表明，在研究期间呼吸医学领域存在显著的研究活动。虽然呼吸医学研究的主要产出地区来自西欧和美国，但加拿大和大洋洲在调整人口和GNIPC后表现最佳。
