Insights

In central Mexico, 5.7% of children aged 6-13 had prediabetes, linked to insulin resistance, not obesity. This significant finding highlights geographic and metabolic factors in pediatric prediabetes.

Area of Science:

  • Pediatric Endocrinology
  • Metabolic Health
  • Public Health Research

Background:

  • Prediabetes prevalence and risk factors in children are critical public health concerns globally.
  • Understanding geographic and metabolic associations is key to developing targeted interventions.
  • Central Mexico presents a unique demographic for studying pediatric metabolic health trends.

Purpose of the Study:

  • To determine the frequency, distribution, and associated factors of prediabetes in children from central Mexico.
  • To investigate the relationship between prediabetes, insulin resistance, and lifestyle factors in a pediatric cohort.
  • To compare prediabetes prevalence in rural versus urban settings and across different geographic locations.

Main Methods:

  • Cross-sectional study involving 1238 children aged 6-13 years from San Luis Potosí, León, and Querétaro.
  • Data collection included family history, somatometry, fasting glucose, insulin, and lipid profiles.
  • Homeostasis Model Assessment of Insulin Resistance (HOMA-IR) was calculated to assess insulin resistance.

Main Results:

  • A 5.7% frequency of prediabetes (fasting glucose 100-125 mg/dL) was observed; no type 2 diabetes cases were found.
  • Children with prediabetes exhibited higher HOMA-IR scores and elevated total and HDL cholesterol levels.
  • Prediabetes was more common in León, with similar prevalence in rural and urban children. Insulin resistance affected 24.1% of participants, higher in urban areas and San Luis Potosí.

Conclusions:

  • Prediabetes is a significant issue among children in central Mexico, associated with insulin resistance and geographic location (León).
  • The study found no association between prediabetes and obesity or urban versus rural dwelling.
  • Findings underscore the importance of metabolic screening and tailored public health strategies for pediatric prediabetes in the region.

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...

Type I Diabetes III: Clinical Manifestations

Type 1 diabetes mellitus typically presents with rapid-onset symptoms due to the body’s inability to utilize glucose in the absence of insulin. Since insulin is required for glucose uptake into cells, its deficiency leads to hyperglycemia and cellular energy deprivation, resulting in characteristic clinical features.Polyuria and PolydipsiaOne of the earliest, most prominent symptoms is polyuria (excessive urination). When blood glucose concentrations rise above the renal threshold, the kidneys...

Type II Diabetes Mellitus III: Clinical Manifestations and Diagnosis

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...

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...

Type I Diabetes II: Pathophysiology

Type 1 diabetes mellitus arises from an immune-mediated destruction of pancreatic β-cells, resulting in an absolute deficiency of insulin. This process develops in genetically susceptible individuals when autoimmunity, environmental exposures, and immunologic dysregulation converge to trigger a targeted attack on the insulin-producing cells of the pancreas. The β-cells are located within the islets of Langerhans and are essential for regulating blood glucose by facilitating cellular uptake of...

Type 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...
