Continuous Glucose Monitoring to Measure Effect of Glycemic Index
The Effect of Glycemic Index on Post-prandial Glycemia (Breakfast vs. Lunch) in Patients With Type 1 Diabetes: Quantification With Continuous Glucose Monitoring
Background: Post-prandial hyperglycemia is common in people with type 1 diabetes.
Objective: The aim was to determine the impact of low vs high glycemic index (GI) on post-prandial glycemia for breakfast vs lunch and to quantify these effects with continuous glucose monitoring.
Design: Seven adult subjects with type 1 diabetes participated in two experiments, each consisting of two meals each. In one experiment, both meals had a low GI; in the other, high GI. Meals were given 195 minutes apart and were matched for carbohydrate, protein, and fat content. Each subject received his usual pre-prandial insulin dosage, followed by a continuous subcutaneous basal insulin infusion for the remainder of the experiment. Arterialized venous glucose was analyzed every 15 minutes and sensor glucose was recorded every 5 minutes.

Mean Area Under the Curve for Rise in Breakfast Post-prandial.
時間枠:Mean area under the curve was calculated at 0, 15min, 30 min, 45 min, 60min, 75 min, 90 min, 105 min, 120min, 135min, 150min, 165min and 180 min after breakfast
|
Arterialized blood glucose was monitored at 15 minute intervals and sensed glucose was recorded at five minute intervals.
Mean area under the curve was calculated over the 3 hour period after breakfast for both the high and low glycemic breakfast meals.
