Insights

Obese children, regardless of metabolic health, show increased carotid intima-media thickness (CIMT), indicating a higher cardiovascular disease risk compared to normal-weight children. Obesity itself is a significant risk factor for heart disease.

Area of Science:

  • Pediatric Endocrinology
  • Cardiovascular Health
  • Metabolic Syndrome

Background:

  • Childhood obesity is a growing concern with potential long-term health implications.
  • Metabolically healthy obese (MHO) children may still face elevated cardiovascular disease (CVD) risks.
  • Obese children with metabolic disorders (MUO) are known to have increased CVD risk.

Purpose of the Study:

  • To assess cardiovascular disease risk in MHO children, MUO children, and normal-weight controls.
  • To compare carotid intima-media thickness (CIMT) as a marker of subclinical atherosclerosis among these groups.
  • To determine if metabolic health status modifies CVD risk in obese children.

Main Methods:

  • Carotid Doppler ultrasound was used to measure CIMT in 204 obese children (42 MHO, 162 MUO) and 99 normal-weight controls.
  • Metabolic parameters (glucose, lipids) and anthropometric data were collected for all participants.
  • Statistical analysis, including analysis of variance, was employed to compare CIMT across groups.

Main Results:

  • Mean CIMT was significantly higher in both MHO and MUO children compared to normal-weight controls (p < 0.01).
  • No significant difference in mean CIMT was observed between MHO and MUO children.
  • Obesity was associated with increased CIMT, irrespective of the presence of metabolic abnormalities.

Conclusions:

  • Childhood obesity is an independent risk factor for cardiovascular disease.
  • Increased CIMT in obese children suggests subclinical atherosclerosis, even in the absence of metabolic disorders.
  • Early identification and management of obesity are crucial for preventing future cardiovascular events.

Pharmacokinetics in Obese Patients: Drug Metabolism and Excretion

Drug metabolism, a critical process in the liver, involves two primary phases: Phase I reactions and Phase II conjugation. Obesity introduces significant alterations in this metabolic process, primarily due to fatty infiltration of the liver, leading to conditions such as nonalcoholic fatty liver disease (NAFLD). This condition can modify the activities of both Phase I and II enzymes, impacting how drugs are metabolized in obese patients.Phase I metabolism sees variable effects across...

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...

Overview of Metabolism

Living cells constantly carry out various chemical reactions which are necessary for their proper functioning. These reactions are interlinked to one another via multiple pathways. The collection of these chemical reactions is known as metabolism.
Plant Metabolism
Sunlight, the primary source of energy in plants, is first absorbed by the chlorophyll pigments present in their leaves. Plants then use this energy to carry out photosynthesis, where water is oxidized into oxygen and carbon dioxide...

Regulation of Metabolism01:19

Regulation of Metabolism

Cellular needs and conditions vary from cell to cell and change within individual cells over time. For example, the required enzymes and energetic demands of stomach cells are different from those of fat storage cells, skin cells, blood cells, and nerve cells. Furthermore, a digestive cell works much harder to process and break down nutrients during the time that closely follows a meal compared with many hours after a meal. As these cellular demands and conditions vary, so do the amounts and...

Metabolic Rate01:25

Metabolic Rate

The human body is a powerhouse of energy, with every cell performing numerous functions that require energy. This energy production and consumption is measured by the metabolic rate, which quantifies the total heat generated by all the body's chemical reactions and mechanical work. This measurement helps to determine the rate of kilocalorie (kcal) consumption needed to fuel all ongoing activities.
The Basal Metabolic Rate (BMR) measures the energy expended at rest.
