View original scientific description
This is a study to develop and evaluate a peer mentoring intervention for Black and Latinx adolescents with type 1 diabetes to increase the initiation and maintenance of a continuous glucose monitoring (CGM) device. This device is a standard of care to improve diabetes management related to diet, exercise, and insulin. Use of CGM has been shown to improve health outcomes, but is not used by adolescents of color. Peer mentors may help improve usage.
Interventions
BEHAVIORAL
Glu-COACH
peer-mentoring support from a peer of the same cultural identity and access to a private social media group for all Black and Latinx teens
Primary outcome measures
Mean hours per week CGM worn
Time frame: 3 months and 6 months
Mean hours per week of documented CGM wear. This will be documented through the CGM program. The primary analysis will be CGM use time at 6 months between the two groups.

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
