Summary
Pediatricians and family physicians are increasingly adopting Hemoglobin A1c (HbA1c) for adolescent type 2 diabetes screening, influenced by new guidelines. This shift may impact detection rates and healthcare costs.
Area of Science:
- Pediatric Endocrinology
- Public Health
- Clinical Practice Guidelines
Background:
- Type 2 diabetes (T2D) screening in adolescents is crucial for early detection and management.
- The 2010 American Diabetes Association (ADA) guidelines recommended Hemoglobin A1c (HbA1c) for T2D screening.
- Understanding current screening practices is essential to assess guideline implementation.
Purpose of the Study:
- To characterize pediatrician and family physician screening practices for adolescent T2D.
- To examine the impact of 2010 ADA guidelines on screening test selection, particularly HbA1c.
Main Methods:
- Cross-sectional mail survey of 1,400 U.S. pediatricians and family physicians.
- Assessed physician ordering practices for T2D screening tests using a hypothetical scenario.
- Collected data on awareness of and intended changes based on ADA guidelines.
Main Results:
- 58% of physicians ordered HbA1c, with 22% using it alone or with nonfasting tests.
- Only 38% were aware of the 2010 ADA HbA1c screening guidelines.
- Post-guideline awareness, 84% would order HbA1c, indicating a significant practice shift.
Conclusions:
- Physician adoption of HbA1c for adolescent T2D screening is increasing following ADA guideline recommendations.
- This shift may lead to fewer fasting tests but has potential implications for detection rates and healthcare costs due to HbA1c's characteristics in children.

01:25Type II Diabetes Mellitus III: Clinical Manifestations and Diagnosis
Type 2 diabetes mellitus develops gradually and is often asymptomatic in early stages.Clinical ManifestationsWhen symptoms appear, they include fatigue, blurred vision, pruritus, delayed wound healing, and recurrent infections, particularly candidal infections. Peripheral neuropathy may present as numbness or tingling in the extremities. Classic hyperglycemia symptoms—polyuria, polydipsia, and polyphagia—are less common. Most patients are overweight and frequently have associated hypertension...
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...
01:15Diabetes: 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 based on...
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...
01:24Type 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.
01:22Diabetes Mellitus: Overview and Type I Subtype
Diabetes mellitus is a chronic metabolic disorder characterized by high blood glucose levels due to inadequate insulin production, insulin resistance, or both. The condition affects millions worldwide and can significantly impact their health and quality of life.
