Validating a prognostic model
Type 2 diabetes is caused by insulin resistance and is more common in patients who are obese.2 Previously thought to primarily affect adults, type 2 diabetes is now being diagnosed more often in children and adolescents with obesity. Similar genetic features and different islet cell autoantibody pattern of latent autoimmune diabetes in adults (LADA) compared with adult-onset type 1 diabetes with rapid progression.

End-organ damage and complications are similar in both types of diabetes. Preventive Services Task Force (USPSTF) recently updated recommendations and suggests screening individuals 40 to 70 years of age who are overweight or obese.

Transferring existing problems in medical practice to a research setting is a challenging process that requires careful consideration.
The practice of clinical epidemiology aims to address this through the application of established approaches for research in human populations, while at all times focussing on the problem at hand from a clinical perspective.
Patients 40 to 70 years of age who are overweight or obese should be screened for type 2 diabetes.
Randomized trials show that screening for type 2 diabetes does not reduce mortality after 10 years, although some data suggest mortality benefits after 23 to 30 years. Individuals at higher risk should be considered for earlier and more frequent screening.
Lifestyle and pharmacologic interventions decrease progression to diabetes in patients with impaired fasting glucose or impaired glucose tolerance. The American Diabetes Association recommends screening for type 2 diabetes annually in patients 45 years and older, or in patients younger than 45 years with major risk factors.
Screening for type 1 diabetes is not recommended for the following reasons: patients typically present with an acute onset of symptoms, no established cutoff value is available for antibody tests, no accepted treatment exists for patients who are asymptomatic, and no medication is available to prevent the disease in persons genetically predisposed to type 1 diabetes.56Screening is recommended for type 2 diabetes because reliable tests are available, and lifestyle changes and medications reduce progression and adverse sequelae of the disease, even in persons who are initially asymptomatic.710 studies show that lifestyle and pharmacologic interventions in patients with impaired glucose tolerance and impaired fasting glucose can delay development of type 2 diabetes,11 with some studies showing greater effectiveness with lifestyle changes.1215 One randomized trial showed a statistically significant reduction in the incidence of all-cause and cardiovascular mortality in patients with impaired glucose tolerance treated with lifestyle modifications, although only after 23 years of follow-up (not found at 20-year evaluation). Persons with abnormal results should be referred for intensive behavioral counseling interventions focusing on physical activity and a healthy diet.

Racial and ethnic differences in mean plasma glucose, hemoglobin A1c, and 1,5-anhydroglucitol in over 2000 patients with type 2 diabetes. Islet cell antibodies and glutamic acid decarboxylase antibodies, but not the clinical phenotype, help to identify type 1(1/2) diabetes in patients presenting with type 2 diabetes.

Clinicians should consider screening certain individuals at higher risk.78 The USPSTF relied on evidence from randomized trials to identify populations who would be most likely to benefit from screening. https://org/patient-care/clinical-recommendations/all/ Management of newly diagnosed type 2 diabetes mellitus (T2DM) in children and adolescents [published correction appears in Lapolla A, Mosca A, Fedele D.It is estimated that in the next 20 years, the number of persons with type 2 diabetes in the United States will reach 44 million, approximately double the current prevalence.3 Diabetes likely will continue to be one of the most common diagnoses made by family physicians.4 Diagnostic testing should be performed in individuals with a clinical history indicative of diabetes.
