Summary
Adding continuous glucose monitoring (CGM) to the National Diabetes Prevention Program (DPP) is feasible and acceptable for prediabetes participants. This intervention shows promise for improving glucose awareness and promoting lifestyle changes.
Area of Science:
- Lifestyle interventions
- Diabetes prevention
- Behavioral science
Background:
- The National Diabetes Prevention Program (DPP) aims to prevent type 2 diabetes through lifestyle changes, but participant success in weight loss and dietary modification is often limited.
- Continuous glucose monitoring (CGM) effectively raises awareness of diet and activity impacts on glucose in individuals with diabetes.
- The feasibility of integrating CGM into behavioral interventions for prediabetes has not been previously studied.
Purpose of the Study:
- To assess the feasibility and acceptability of incorporating a brief CGM intervention into the Arizona Cooperative Extension National DPP.
- To explore participant experiences, including facilitators and barriers, regarding CGM use within a prediabetes prevention program.
Main Methods:
- A prospective study involving DPP participants invited to a single CGM education session and a 10-day CGM wear period.
- Participants reflected on behaviors related to hyperglycemic events and completed an acceptability survey.
- Focus groups were conducted to gather qualitative data on CGM utility and user experience, analyzed via the Key Point Summary (KPS) method.
Main Results:
- High opt-in participation (77%) and education session attendance (89%) met feasibility benchmarks.
- CGM demonstrated high acceptability, with 96% of participants believing it should be offered within the DPP.
- Participants reported using CGM insights to implement behavior changes, such as dietary adjustments and increased physical activity.
Conclusions:
- Integrating a brief CGM education session and 10-day wear period into the DPP is feasible and well-accepted by participants with prediabetes.
- CGM shows potential as a tool to enhance self-awareness and drive behavior change for glucose management.
- Further research is warranted to determine the efficacy of CGM-enhanced DPP interventions on health outcomes and behavioral improvements.

2.3K
Type 2 diabetes, characterized by insulin resistance, arises when the insulin receptors on cells lose responsiveness to insulin, diminishing the cell's capacity to take up glucose, resulting in elevated blood glucose levels. To receive a diagnosis of Type 2 diabetes, a series of blood glucose tests are necessary to assess whether the blood glucose falls within normal parameters. If the result is out of the normal range, a patient may be diagnosed as prediabetic or diabetic, depending on the...

The therapy for diabetes aims to alleviate hyperglycemia-related symptoms, prevent acute metabolic decompensation, and reduce chronic end-organ complications. Glycemic control is evaluated through short-term (self-monitoring, continuous glucose monitoring) and long-term (A1c, fructosamine) metrics, enabling near real-time tracking of blood glucose levels and reflecting glycemic control over specific time frames.

For most patients, experiencing several weeks of polyuria, polydipsia, fatigue, and significant weight loss may indicate the presence of diabetes. Furthermore, adults displaying the phenotypic appearance of type 2 diabetes (particularly those who are obese and not initially insulin-requiring), may have islet cell autoantibodies, suggesting autoimmune-mediated β cell destruction and a diagnosis of latent autoimmune diabetes of adults (LADA). The categorization of glucose homeostasis is...
