Current Scientometric Trend in Soy and Cancer Research Hsin-Chieh Chu1*, Mei-Su Pan1, Yee-Shuan Lee2 and Yuh-Shan Ho2# 1School of Nutrition and Health Sciences, Taipei Medical University 2Bibliometric Centre, Taipei Medical University - Wan-Fang Hospital Introduction Asian has long history of rich soy diet and the correlation of soy intake and incidences of various cancers occurring have been studied.1 Although no evidence has shown recommended amounts of soy products can efficiently prevent cancer, but research related to soy diet and cancer has been widely studied across the world. The purpose of this study was to conduct a publication analysis of soy and cancer related publications and theorized that the popularity of this topic was shown by an increase of yearly publication production. We also theorized that since Asian has rich-soy diet, substantial amount of research would be done by international collaboration between Asian and other countries and within. Methodology Analysis based on: Science Citation Index (SCI) indexed publications Published between 1991 to 2002 Included keywords soy and cancer Analysis parameter: Yearly production (P) Citation per Publication (CPP) Total citation/Total publication Authorship Number of authors Country of origin Results Yearly production increased 20 times more than a decade ago Total production: 677 Average annual production: 56.4 CPP decline expected due to visibility bias Authorship did not affect P or CPP significantly Domination of small group authorship Left: Region origin of corresponding author Top: Region of origin of the other authors Table of percentage share of collaboration between the regions Region Asia Europe Northern America Oceania Africa Southern America - 1.12 2.25 11.2 24.7 20.2 16.9 5.62 North American countries dominated international collaborated publications %P: Production percentage share C: Total citation Conclusion Dramatic increase of yearly publication indicated soy and cancer research has become a recent focus Western countries domination of production has rejected our theory but Asian countries has shown equal level of citation frequency according to CPP values High CPP values may correspond to low percentage of international collaboration due to necessary information were carried by citation instead of collaboration Region Country # P %P C CPP Africa 2 1 0.17 3 Asia 8 57 9.69 632 11.1 Europe 16 92 15.6 1590 17.3 Northern America 327 55.6 3296 10.1 Oceania 25 4.25 400 16.0 Southern America Northern American countries dominate single country publication output and citation frequency All world regions show independent research activity Reference Adlercreutz H, Mazur W (1997), Phyto-oestrogens and Western diseases.
