Chicago, Illinois 60637


Purpose:

The use of sugar and starch-like foods for energy (carbohydrate metabolism) changes when people sleep. However, it is still not known if differences in the amount of nighttime sleep have an effect on the carbohydrate metabolism of people who have a relative with type 2 diabetes (parent, sibling, or grandparent). This study is being done to test the hypothesis that individual differences in habitual sleep duration may be related to differences in the carbohydrate metabolism of people who have a history of type 2 diabetes in their family.


Study summary:

On two consecutive inpatient days, the participants in this study will undergo two different tests. The first test will determine how much insulin can their body produce in response to an intravenous glucose infusion over a period of several hours. The second test will determine how effective is the action of the sugar-processing hormone, insulin, in their body when it is infused intravenously together with glucose over a period of several hours.
