This project examines how risk is made into an object of biomedical intervention. It will explore how biomedical risk practices and discourses are transforming contemporary social life. To illuminate these processes, the investigators will study the phenomenon of pre-diabetes in an urban environment. Pre-diabetes is a new and rapidly expanding diagnostic category. The use of the term speaks to new methods of surveillance and management of glucose in the bloodstream. It is creating a wide and growing at risk population that is situated between ill and healthy.
