Workshop Agenda
March 2–3, 2015
National Institute of Environmental Health Sciences
Building 101, Rodbell ABC
111 T.W. Alexander Drive
Research Triangle Park, NC
Workshop Objectives:
The workshop will explore the role of chemical exposures in the development of obesity through sessions focused on a life span view, possible biologic pathways and environmental influences, and effects of food additives and antibiotics. Speakers will make links between exposure to environmental chemicals and increased incidence of weight gain, glucose tolerance and insulin sensitivity, inflammation, and aspects of metabolic syndrome in animal models and human studies. Two panels at the end of the workshop will provide a chance to discuss opportunities for new research and possible policy actions to address exposure to chemicals associated with the development of obesity.
