Insights

Maternal hyperglycemia during pregnancy increases offsprings' cardiometabolic risks, including abnormal glucose tolerance and obesity by age 7. These effects were more pronounced in girls for adiposity.

Area of Science:

  • Endocrinology
  • Pediatrics
  • Public Health

Background:

  • Maternal hyperglycemia during pregnancy is a growing concern.
  • Gestational diabetes mellitus (GDM) affects a significant number of pregnancies.
  • The long-term cardiometabolic health of offspring exposed to maternal hyperglycemia requires further investigation.

Purpose of the Study:

  • To evaluate the impact of maternal hyperglycemia during pregnancy on cardiometabolic risk factors in offspring during early childhood.
  • To determine the association between maternal glucose levels and offspring's glucose tolerance, BMI, blood pressure, and adiposity at age 7.

Main Methods:

  • A cohort of 970 mothers and their children from the Hyperglycemia and Adverse Pregnancy Outcome study were reevaluated 7 years postpartum.
  • Gestational diabetes mellitus (GDM) was diagnosed using World Health Organization 2013 criteria.
  • Offspring cardiometabolic risk factors including glucose tolerance, BMI, blood pressure, and adiposity were assessed.

Main Results:

  • Offspring born to mothers with GDM exhibited higher rates of abnormal glucose tolerance, overweight/obesity, greater BMI, and higher blood pressure compared to controls.
  • Increased maternal glucose levels during pregnancy were associated with a higher risk of abnormal glucose tolerance in offspring.
  • Maternal hyperglycemia was linked to increased adjusted odds ratios for childhood overweight/obesity and adiposity in girls, but not boys.

Conclusions:

  • Maternal hyperglycemia during pregnancy is an independent risk factor for abnormal glucose tolerance, obesity, and elevated blood pressure in offspring at 7 years of age.
  • The impact of maternal hyperglycemia on childhood adiposity was observed specifically in girls.
  • These findings underscore the importance of managing maternal glucose levels during pregnancy for long-term offspring cardiometabolic health.

Pathophysiology 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,...

Diabetes 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...

Overview of Carbohydrate Metabolism

Carbohydrate metabolism is a fundamental biochemical process that ensures a constant supply of energy to living cells. The most important carbohydrate is glucose, which can be broken down via glycolysis to enter into the Krebs cycle and eventually lead to the production of ATP through oxidative phosphorylation.
Glucose transport into cells is facilitated by a family of transport proteins called GLUT (Glucose Transporters). GLUT4 is the primary glucose transporter for insulin-stimulated glucose...

Diabetes 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.
Type 1 diabetes is an autoimmune disease in which the immune system mistakenly attacks and destroys the insulin-producing beta cells in the pancreas. As a result, the body is unable to produce sufficient insulin, and individuals with...

Carbohydrate Metabolism

Carbohydrates are polymers composed of molecules containing atoms of carbon, hydrogen and oxygen. One gram of carbohydrate can provide four kilo-calories of energy, which makes it the most efficient instant energy source.
Starch accounts for approximately 60% of the carbohydrates consumed by humans. Since amylase enzymes cannot function in the stomach's acidic environment, starch can only be digested in the mouth and small intestine. Simple sugars are found naturally in milk and fruits in...

Diabetes: 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...
