Insights

This study found low overweight/obesity rates in rural Mexican children, but identified risks for increased body fat and insulin resistance. Early life growth velocity impacts insulin resistance in this population.

Area of Science:

  • Pediatric Endocrinology
  • Nutritional Science
  • Public Health

Background:

  • Limited data exists on overweight, obesity, body composition, and insulin resistance in rural children.
  • Characterizing these health indicators is crucial for understanding pediatric health in underserved communities.

Purpose of the Study:

  • To assess adiposity and insulin resistance (homeostasis model assessment of insulin resistance - HOMA-IR) in rural Mexican school-aged children.
  • To identify factors associated with fat mass and HOMA-IR in this population.

Main Methods:

  • Studied 41 school-aged children (9.9 ± 2.5 years) from a Mexican rural community.
  • Assessed nutritional status from infancy, anthropometry, energy intake, physical activity, body composition, and biochemical markers.

Main Results:

  • Prevalence of overweight/obesity was 7.3%; mean energy intake was below recommendations.
  • Females had higher fat mass percentage than males (p = 0.006).
  • Early life growth velocity correlated with HOMA-IR; female gender was linked to higher fat mass.

Conclusions:

  • Rural Mexican children exhibit low overweight/obesity frequency but face risks for adiposity and insulin resistance.
  • Growth velocity in early life is a significant factor associated with insulin resistance in this cohort.

Obesity01:24

Obesity

The Body Mass Index (BMI) is a numerical value derived from a person's weight and height, used to categorize individuals into weight ranges. It is calculated using the formula: weight in kilograms divided by height in meters squared. Obesity is a health condition characterized by excessive accumulation of adipose tissue that poses health risks, often diagnosed with a BMI ≥ 30. This excess fat storage occurs when surplus dietary calories are converted into triglycerides and stored in...

Diabetes Mellitus: Type 2 and Gestational01:22

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...

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...

Insulin: Dosing Regimen and Adverse Effects01:16

Insulin: Dosing Regimen and Adverse Effects

Insulin-replacement therapy usually includes both long-acting insulin (basal) and short-acting insulin (to cater to postprandial needs). In a diverse group of type 1 diabetes patients, the average daily insulin dose is typically 0.5-0.7 units/kg body weight. However, obese patients and pubertal adolescents may need more due to insulin resistance.
The basal dose constitutes about 40%-50% of the total daily dose, with the rest as premeal insulin. The mealtime insulin dose should mirror...

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...

Carbohydrate Metabolism01:36

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...
