Description

Various CGMs are approved by the U.S. Food and Drug Administration (FDA) for use in children and adults with diabetes. However, to date, little is known about how CGM technology can be integrated into weight management strategies for adolescents with obesity. No study to date has explored the effects of unblinded vs. blinded CGM use alone, without any other lifestyle modification recommendations. Thus, to address this question, this is a cross-over feasibility trial of blinded vs. unblinded CGM use in youth with obesity. This study hypothesizes that CGM will be a feasible and acceptable technology for youth with obesity, without diabetes, to utilize, and that access to daily glucose trends will facilitate positive changes in eating behavior and daily activity level compared to blinded CGM use. Thirty adolescents with obesity will be recruited into a six-week cross-over trial. All participants will be randomly assigned to either the blinded or unblinded group for three weeks. And then cross over to the other group for another three weeks. The primary endpoints are recruitment, retention, and adherence. While the secondary endpoints are glycemic variability, as captured on CGM, change in weight as an excess percentage of 95th percentile, sleep, dietary intake, physical activity, and eating behaviors.
