CGM and Lifestyle Changes in Patients With Impaired Glucose Tolerance
What this study is about
The incidence of type 2 diabetes (T2D) in children is increasing, paralleling the rising incidence of obesity. Preventing children and adolescents from developing T2D is critical. The health benefits of lifestyle modifications are well documented in this population, but success rates are low.
View original scientific description
The incidence of type 2 diabetes (T2D) in children is increasing, paralleling the rising incidence of obesity. Preventing children and adolescents from developing T2D is critical. The health benefits of lifestyle modifications are well documented in this population, but success rates are low. Obesity in children and adolescents increases the risk of not only T2D but other complications as well, such as hypertension, dyslipidemias and more. The investigators hypothesize that having real-time glucose data with the use of a continuous glucose monitor (CGM) in obese patients with impaired glucose tolerance will improve adherence to lifestyle modifications. As a result, a decrease in body mass index (BMI) is expected with subsequent improvement in insulin sensitivity, thus reducing risk of obesity-related complications later in childhood/adolescence and adulthood.
Who can participate
This study lists these criteria on ClinicalTrials.gov. A study coordinator reviews eligibility during screening — this page does not determine whether you qualify.
Inclusion criteria
- Children 10 to \<18 years old (i.e., before their 18th birthday)
- Impaired glucose tolerance based on standardized oral glucose tolerance test (OGTT) or fasting glucose per American Diabetes Association criteria,
- Overweight or obese (BMI ≥85th percentile for age/sex)
- Patients are pubertal, defined as females with breast Tanner stage II or above, or males with testicular volume ≥4 mL
Exclusion criteria
- Existing diagnosis of type 1 or type 2 diabetes
- Prepubertal
- Taking medications that affect insulin sensitivity (e.g.,chronic corticosteroids whether systemic or inhaled). Metformin allowed if stable dose.
- Patients and/or families not willing to wear the CGM for the duration of the study period or lack of compliance after recruitment
Where
- Jacksonville, Florida
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.
