Prediabetes Clinical Trials

This is a cluster-randomized controlled trial of NDPP-Flex versus the standard NDPP to evaluate effects on glycemia, heterogeneity of treatment effects, and mechanisms of change. We will recruit 200 diverse adults with prediabetes (A1C 5.7-6.4%) and normal weight or overweight/obesity. Participants will enroll in classes (N=20) that are randomized to deliver NDPP-Flex or the standard NDPP. The trial is designed to have >95% power to detect anticipated treatment effects of ~0.2% A1C improvement and ~10% increase in participants who reach normoglycemia compared to the control arm. The study will be conducted in a health system with the 6th largest network of FQHCs in the US (Denver Health) and in partnership with a premier research institution (University of Colorado).

This 12-week controlled diet and weight intervention study seeks to define the molecular pathways that link excess body weight to the development of insulin resistance (IR). Blood, adipose and stool are sampled at three timepoints; baseline, peak weight (4 weeks) and post weight loss to monitor changes in cellular processes. Additionally, direct insulin sensitivity testing, and radiological measurement of visceral fat and intrahepatic fat content is measured at three timepoints to correlate clinical indices with cellular changes.

This study is being done to better understand whether meal replacements can be an effective tool for weight loss and treatment of elevated blood sugars in people with obesity/overweight and diabetes/pre-diabetes who have a low income. Read Less

This study will use continuous glucose monitoring and actigraphy to examine whether a personalized, daily sleep extension intervention improves glucose regulation for community dwelling, sleep-restricted adults with pre-diabetes. The randomized controlled trial will include 150 adults with pre-diabetes. Sleep extension and habitual sleep groups will complete daily sleep diaries and participate in a weekly 15-minute telephone call or videoconference meeting with a member of the study team (8 sessions total). Data collection will be at 2 time points: pre-randomization and post-intervention (completion of the 8-week intervention). Changes in the percent time glucose is ≥ 140mg/dL at baseline and post-intervention will be established and compared across the sleep extension and habitual sleep arms. Read Less

Millions of Americans have diabetes or prediabetes, for which regular physical activity can reduce risks of unfavorable outcomes of these conditions. This study will test the effects of an evidence-based intervention in the primary care setting on increasing physical activity among these individuals. If effective, it can be broadly implemented in primary care. Read Less
