This site provides data gathered in response to questions about diabetes at each research clinic visit.  All of the data in this section is based on self-report.  For diabetes medications based on review of medications brought to research clinic visits, see the Medications data group. For biological measures of diabetes, including fasting and post-challenge plasma glucose levels, see the Labs data group.  Fasting glucose levels were obtained at Visit 1 through Visit 10; 2hr oral glucose tolerance tests were performed at Visit 4 and Visit 7.  Not all participants at Visit 5 were asked to fast; hours fasting is provided in the Labs data group. 

PENDING: Additional self-report data on diabetes based on annual Mailers will be available by the end of 2019.
