Insights

Peer support may help individuals with prediabetes make healthy lifestyle changes to prevent type 2 diabetes mellitus (T2DM). This randomized trial will assess the effectiveness of peer coaching versus usual care.

Area of Science:

  • Diabetes prevention research
  • Behavioral science in health

Background:

  • Type 2 diabetes mellitus (T2DM) prevention requires effective and scalable interventions.
  • Engagement in healthy lifestyle changes is often low, particularly among minority and low-income populations.
  • Prediabetes increases the risk of developing T2DM.

Purpose of the Study:

  • To evaluate the effectiveness of a peer support intervention in preventing or delaying T2DM onset.
  • To compare a peer support arm with enhanced usual care in a pragmatic trial.

Main Methods:

  • A randomized controlled pragmatic trial involving 296 adults with prediabetes.
  • Participants were randomized to either a peer support group or enhanced usual care.
  • The peer support intervention included initial face-to-face meetings and ongoing weekly/monthly calls from a trained peer coach.
  • Outcomes assessed included changes in A1c, weight, and waist circumference.

Main Results:

  • Enrollment of at least 296 participants and approximately 75 peer supporters.
  • The study is designed to assess changes in key health indicators and patient-centered outcomes.

Conclusions:

  • Peer coaching offers a potential strategy to improve adherence to healthy behaviors for T2DM risk reduction.
  • Ongoing support from peer coaches may facilitate sustained behavior change in individuals at risk for T2DM.

Diabetes: Management and Pharmacotherapy

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.

Stress Prevention and Stress Management Techniques VI

Adopting a healthier lifestyle often requires overcoming significant challenges, but leveraging psychological, social, and cultural resources can facilitate meaningful change. Effective self-change hinges on understanding and applying key tools such as motivation and goal setting, which help sustain efforts toward long-term health benefits.
Motivation and Self-Determination
Motivation, the driving force behind behavior, plays a pivotal role at every stage of the change process. The research...

Pathophysiology of Diabetes01:20

Pathophysiology of Diabetes

Diabetes mellitus is a chronic metabolic disorder characterized by hyperglycemia. The four categories of diabetes are type 1 diabetes, type 2 diabetes, other specific types of diabetes, and gestational diabetes.
Type 1 diabetes is characterized by autoimmune-mediated destruction of pancreatic β cells, with environmental factors potentially triggering this process in genetically susceptible individuals. Despite many not having a family history, certain genes increase susceptibility,...

Diabetes Mellitus: Type 2 and Gestational

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...

Diabetes: Symptoms, Diagnosis, and Complications

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...

Hormones Regulating Blood Glucose01:16

Hormones Regulating Blood Glucose

Insulin is released by beta cells of the pancreas when blood glucose levels are high. It facilitates glucose absorption and utilization in insulin-dependent cells with insulin receptors on their plasma membranes. Insulin promotes glucose uptake by increasing the number of glucose transport proteins in the cell membrane, allowing glucose to enter the cell. As a result, glucose utilization and ATP production are enhanced.
In addition to accelerating glucose uptake and utilization, insulin has...
