NIEHS extramural global environmental health portfolio: Opportunities for collaboration

Abstract

Background: Global environmental health has emerged as a critical topic for environmental health researchers and practioners. Estimates of the environmental contribution of total world-wide disease burden range from 25 to 33%. Objective: We reviewed grants funded by the National Institute of Environmental Health Sciences (NIEHS) during 2005-2007 to evaluate the costs and scientific composition of the global environmental health portfolio, with the ultimate aim of strengthening global environmental health research partnerships. Methods/Results: We examined NIEHS grant research databases to identify the global environmental health portfolio. In the past 3 fiscal years (2005-2007), the NIEHS funded 57 scientific research projects in 37 countries, at an estimated cost of $30 million. Metals such as arsenic, methylmercury, and lead are the most frequently studied toxic agents, but a wide range of stressors, routes of exposure, and agents are addressed in the portfolio. Conclusions: The portfolio analysis indicates that there is a firm foundation of research activities upon which additional global environmental health partnerships could be encouraged. Current data structures could be strengthened to support more automated analysis of grantee information.
