ABSTRACT:       Background: Passive exposure to environmental tobacco
smoke (ETS) is estimated to exert a major burden of disease. Currently,
numerous countries have taken legal actions to protect the population
against ETS. Numerous studies have been conducted in this field.
Therefore, scientometric methods should be used to analyze the
accumulated data since there is no such approach available so far.

Methods and Results: A combination of scientometric methods and novel
visualizing procedures were used, including density-equalizing mapping
and radar charting techniques. 6,580 ETS-related studies published
between 1900 and 2008 were identified in the ISI database. Using
different scientometric approaches, a continuous increase of both
quantitative and qualitative parameters was found. The combination with
density-equalizing calculations demonstrated a leading position of the
United States (2,959 items published) in terms of quantitative research
activities. Charting techniques demonstrated that there are numerous bi-
and multilateral networks between different countries and institutions
in
this field. Again, a leading position of American institutions was
found.

Conclusions: This is the first comprehensive scientometric analysis of
data on global scientific activities in the field of environmental
tobacco smoke research. The present findings can be used as a benchmark
for funding allocation processes.
