Abstract:
Study objectives: To evaluate the contribution of different world regions
in respiratory research productivity.
Methods: 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.
Measurements and results: 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%).

Conclusions:
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 hail the best performance after
adjustment for population and GNIPC.
