Summary
Waist circumference (WC) measured between 20-24 weeks of gestation is a good predictor of gestational diabetes mellitus (GDM). A WC of 86-88 cm effectively identifies pregnant women at risk for GDM.
Area of Science:
- Obstetrics and Gynecology
- Maternal-Fetal Medicine
- Endocrinology
Background:
- Gestational diabetes mellitus (GDM) poses risks to both mother and fetus.
- Early identification of GDM risk is crucial for timely intervention.
- Predictive markers for GDM are actively researched.
Purpose of the Study:
- To evaluate the efficacy of mid-pregnancy waist circumference (WC) as a predictor for GDM.
- To determine optimal WC cutoffs for GDM risk assessment.
- To compare the predictive value of WC with body mass index (BMI).
Main Methods:
- A cross-sectional study involving 240 pregnant women at 20-24 weeks gestation.
- Measurement of WC and estimation of prepregnancy and gestational BMI.
- Diagnosis of GDM based on a 75-g oral glucose tolerance test (OGTT).
Main Results:
- 13% of the enrolled women were diagnosed with GDM.
- Prepregnancy BMI, gestational BMI, and mid-pregnancy WC all correlated with GDM risk.
- An optimal WC cutoff of 85.5-88.5 cm was identified for GDM prediction.
Conclusions:
- Mid-pregnancy WC measurement is a valuable tool for predicting GDM.
- WC values between 86-88 cm demonstrate good performance in identifying GDM risk.
- WC offers a practical and accessible method for GDM screening.

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...
01:20Pathophysiology of Diabetes
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, suggesting a...

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...
01:15Diabetes: 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...
01:26Diabetes 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...
01:26Type 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...
