Type 1 Diabetes and Eating Disorder Diurnal Glucose Patterns

The specific aims of the proposed research are to: 2.1 Determine the degree of variation in glycemic profiles of individuals with an Eating Disorder and Type 1 Diabetes (ED-DMT1) and an Eating Disorder only (ED/only); and 2.2 Determine the impact of nutritional intake and planned physical activity on glucose profiles of individuals with ED-DMT1 and ED/only. These aims will be examined by characterizing: * glucose exposure, as measured by area under the Ambulatory Glucose Profile (AGP) median curve; * glucose variability, as measured by the AGP inter-quartile range; and * glucose stability, as measured by change in the AGP median curve.
