Abstract
CONTEXT: The promotion of yoga practice as a preventative and treatment therapy for health outcomes in the western hemisphere is increasing rapidly. As the commercial success of yoga burgeons in popular culture, it is important to investigate the trends of yoga as a therapeutic intervention in academic literature. The free-access search engine, PubMed is a preeminent resource to identify health-related research articles published for academics, health practitioners and others. AIMS: To report the recent yoga-related publications in the western healthcare context with particular interest in the subject and type of yoga titles. MATERIALS AND METHODS: A bibliometric analysis to describe the annual trends in publication on PubMed from January 1950 to December 2012. RESULTS: The number of yoga-related titles included in the PubMed database is limited until a marked increase 2000 and steady surge since 2007. Bibliometric analysis indicates that more than 200 new titles are added per annum since 2011. Systematic reviews and yoga trials are increasing exponentially, indicating a potential increase in the quality of evidence. Titles including pain management, stress or anxiety, depression and cancer conditions are highly correlated with yoga and healthcare research. CONCLUSIONS: The prevalence of yoga research in western healthcare is increasing. The marked increase in volume indicates the need for more systematic analysis of the literature in terms of quality and results.
