Summary
An interdisciplinary lifestyle program significantly improved weight and metabolic health in prediabetes patients, preventing type 2 diabetes development. Group seminars alone were ineffective, highlighting the value of personalized intervention for diabetes prevention.
Area of Science:
- Endocrinology and Metabolism
- Preventive Medicine
- Lifestyle Interventions
Background:
- Prediabetes affects a significant portion of the population, increasing the risk of type 2 diabetes.
- Lifestyle modifications are crucial for managing prediabetes and preventing disease progression.
- Identifying effective and cost-efficient interventions is essential for public health.
Purpose of the Study:
- To compare the effectiveness and cost of two distinct lifestyle-modification programs for individuals at high risk of type 2 diabetes.
- To evaluate the impact of an interdisciplinary approach versus group seminars alone on weight, anthropometric measures, and metabolic variables.
Main Methods:
- A randomized controlled trial involving 48 adults with prediabetes and a BMI ≥27 kg/m(2).
- Intervention group received 1-year interdisciplinary counseling with individual sessions and group seminars; control group received seminars only.
- Outcomes measured included weight loss, waist circumference, glucose levels, lipid profiles, and intervention costs.
Main Results:
- The interdisciplinary group achieved significant weight loss (4.9 kg) and waist circumference reduction (5 cm), unlike the group-seminar-only group.
- 50% of the interdisciplinary group lost ≥5% of initial weight, and 27% lost ≥10%, compared to 12% and 4% in the other group.
- Significant improvements in fasting glucose, 2-hour glucose, and lipid profiles were observed in the interdisciplinary group, with no diabetes development, versus 11.5% in the control group. The interdisciplinary approach cost $733.06/year per subject versus $81.36/year for group seminars.
Conclusions:
- A low-cost, moderate-intensity, individual interdisciplinary approach combined with group seminars is effective for significant weight loss and metabolic improvement in prediabetes.
- Group seminars alone are insufficient for achieving meaningful clinical outcomes in this high-risk population.
- This study supports the use of personalized, interdisciplinary lifestyle interventions for effective prediabetes management and type 2 diabetes prevention.

01:15Diabetes: 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.

01:26Type II Diabetes I: Introduction
Type 2 diabetes mellitus (T2DM) is a chronic metabolic disorder characterized by insulin resistance, in which target tissues such as the liver, muscle, and adipose tissue respond poorly to insulin. It is also associated with inadequate compensatory insulin secretion, where pancreatic β-cells fail to produce sufficient insulin. Together, these abnormalities lead to persistent hyperglycemia.EtiologyT2DM develops through a complex interaction of genetic predisposition and environmental or...
01:22Diabetes 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...
01:26Diabetes Mellitus: Introduction
Diabetes mellitus consists of chronic metabolic disorders characterized by persistent hyperglycemia. This elevated blood glucose results from defects in insulin secretion, impaired insulin action, or both. Insulin, produced by pancreatic β-cells, is essential for maintaining glucose homeostasis by facilitating cellular glucose uptake for energy or storage. Disruptions in insulin production or function lead to glucose accumulation in the bloodstream, causing the clinical features and long-term...
01:12Type I Diabetes I: Introduction
Type 1 diabetes mellitus is a chronic metabolic disorder characterized by an absolute deficiency of insulin resulting from the autoimmune destruction of pancreatic β-cells. Although it can occur at any age, it is most commonly diagnosed in childhood, adolescence, or early adulthood. The loss of insulin production impairs cellular glucose uptake, resulting in persistent hyperglycemia and necessitating lifelong insulin therapy.Autoimmune Destruction of β-CellsThe hallmark of type 1 diabetes is an...
01:24Type II Diabetes II: Pathophysiology
PathophysiologyType 2 diabetes mellitus (T2DM ) is a chronic metabolic disorder characterized by insulin resistance and progressive pancreatic β-cell dysfunction, leading to impaired glucose homeostasis. It results from interactions among genetic predisposition, environmental factors, and metabolic stressors, such as overnutrition and a sedentary lifestyle.Insulin Resistance and Glucose DysregulationEarly T2DM involves insulin resistance in skeletal muscle, adipose tissue, and the liver.
