2016 ADA Standards of Medical Care in Diabetes Guidelines
Categories of Increased risk for diabetes (PREDIABETES)
| "1. Testing to assess risk for future di- abetes in asymptomatic people should be considered in adults of any age who are overweight or obese (BMI $25 kg/m2 or $23 kg/m2 in Asian Americans) and who have one or more additional risk factors for diabetes. (Level of Evidence: B)" |
| "2. For all patients, testing should begin at age 45 years (Level of Evidence: B)" |
| "3. If tests are normal, repeat testing carried out at a minimum of 3-year intervals is reasonable. (Level of Evidence: C)" |
| "4. To test for prediabetes, fasting plasma glucose, 2-h plasma glucose after 75-g oral glucose tolerance test, and A1C are equally appropriate. (Level of Evidence: B)" |
| "5. In patients with prediabetes, iden- tify and, if appropriate, treat other cardiovascular disease risk factors. (Level of Evidence: A)" |
| "6. Testing to detect prediabetes should be considered in children and ado- lescents who are overweight or obese and who have two or more additional risk factors for diabetes (Level of Evidence: E)" |
TYPE 1 DIABETES
| "1. Blood glucose rather than A1C should be used to diagnose acute onset of type 1 diabetes in individuals with symptoms of hyperglycemia. (Level of Evidence: E)" |
| "2. Inform the relatives of patients with type 1 diabetes of the opportunity to be tested for type 1 diabetes risk, but only in the setting of a clinical research study. (Level of Evidence:E)" |
TYPE 2 DIABETES
| "1. Testing to detect type 2 diabetes in asymptomatic people should be con- sidered in adults of any age who are overweight or obese (BMI $25 kg/m2 or $23 kg/m2 in Asian Amer- icans) and who have one or more additional risk factors for diabetes. (Level of Evidence: B)" |
| "2. For all patients, testing should be- gin at age 45 years. (Level of Evidence: B)" |
| "3. If tests are normal, repeat testing carried out at a minimum of 3-year intervals is reasonable. (Level of Evidence: C)" |
| "4. To test for type 2 diabetes, fasting plasma glucose, 2-h plasma glucose after 75-g oral glucose tolerance test, and A1C are equally appropriate. (Level of Evidence: B)" |
| "5. In patients with diabetes, identify and, if appropriate, treat other cardiovascular disease risk factors. (Level of Evidence: B)" |
| "6. Testing to detect prediabetes should be considered in children and ado- lescents who are overweight or obese and who have two or more additional risk factors for diabetes (Level of Evidence: E)" |
GESTATIONAL DIABETES MELLITUS
| "1. Test for undiagnosed type 2 diabe- tes at the first prenatal visit in those with risk factors, using stan- dard diagnostic criteria. (Level of Evidence: B)" |
| "2. Test for gestational diabetes mel- litus at 24–28 weeks of gestation in pregnant women not previously known to have diabetes. (Level of Evidence: B)" |
| "3. Screen women with gestational di- abetes mellitus for persistent diabe- tes at 6–12 weeks postpartum,using the oral glucose tolerance test and clinically appropriate non- pregnancy diagnostic criteria. (Level of Evidence: E)" |
| "4. Women with a history of gesta- tional diabetes mellitus should have lifelong screening for the de- velopment of diabetes or predia- betes at least every 3 years. (Level of Evidence: B)" |
| "5. Women with a history of gesta- tional diabetes mellitus found to have prediabetes should receive lifestyle interventions or metfor- min to prevent diabetes. (Level of Evidence: A)" |
