Screening for gestational diabetes mellitus: U.S. Preventive Services Task Force recommendation statement
Annals of Internal Medicine
|January 16, 2014
Summary
The U.S. Preventive Services Task Force recommends screening for gestational diabetes mellitus (GDM) in pregnant women after 24 weeks of gestation. Evidence is insufficient for screening before 24 weeks.
Area of Science:
- Obstetrics and Gynecology
- Endocrinology
- Preventive Medicine
Background:
- Gestational diabetes mellitus (GDM) poses risks to both mother and infant.
- The U.S. Preventive Services Task Force (USPSTF) previously issued recommendations on GDM screening in 2008.
- Updated evidence necessitates a review of current screening guidelines.
Purpose of the Study:
- To update the 2008 USPSTF recommendation on screening for GDM.
- To evaluate the accuracy, benefits, and harms of GDM screening and treatment.
Main Methods:
- Systematic review of evidence on GDM screening tests.
- Assessment of benefits and harms of screening before and after 24 weeks of gestation.
- Evaluation of treatment benefits and harms for mother and infant.
Main Results:
- Screening for GDM in asymptomatic pregnant women after 24 weeks of gestation is recommended (B recommendation).
- Evidence is insufficient to assess benefits and harms of screening before 24 weeks of gestation (I statement).
Conclusions:
- Routine screening for GDM after 24 weeks of gestation is advised for asymptomatic pregnant women.
- Further research is needed to determine optimal screening timing before 24 weeks.

4.9K
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...

Preventive healthcare services keep people healthy via frequent check-ups, screening, and counseling. They primarily aid in disease prevention rather than treating an acute or chronic illness. Preventive treatment also keeps individuals productive and energetic, allowing them to work well into their retirement years. Examples of preventive care services include:

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...

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,...

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...

Hyperglycemia is an abnormally high blood glucose level. It is diagnosed by fasting glucose ≥126 mg/dL, 2-hour oral glucose tolerance test (or OGTT) ≥200 mg/dL, random glucose ≥200 mg/dL with symptoms, or HbA1c ≥6.5%. However, HbA1c results may be unreliable in certain conditions, such as anemia or hemoglobinopathies, and the diagnosis should be confirmed unless classic symptoms are present. Postprandial hyperglycemia is typically considered significant when glucose...
