Evaluating the Arterial Stiffness as a Useful Tool in the Management of Obese Children

Area of Science:

• Pediatric Cardiology
• Vascular Physiology
• Biomarkers of Cardiovascular Risk

Background:

• Childhood obesity accelerates arterial stiffness and elevates arterial pressure, indicating early vascular wall impairment.
• Early detection of vascular changes in obese children is crucial for long-term cardiovascular health.
• Pulse wave analysis (PWA) offers a non-invasive method to assess arterial stiffness.

Purpose of the Study:

• To evaluate the utility of PWA in quantifying arterial stiffness in obese children.
• To identify correlations between obesity indicators, blood parameters, and arterial stiffness markers.
• To establish PWA as a reliable tool for monitoring vascular health in pediatric obesity.

Main Methods:

• Sixty children (33 obese, 27 normal-weight, aged 6-18) underwent PWA using a Mobil-O-Graph device.
• PWA parameters included pulse wave velocity (PWV), augmentation index (AIx), and various blood pressures.
• Relevant blood parameters (lipids, liver enzymes, vitamin D, hormones) were analyzed from medical history.

Main Results:

• High BMI and waist circumference correlated with increased PWV.
• Lipid profiles (LDL-c, TG, non-HDL-c) and cholesterol ratios significantly correlated with PWV, SBP, and cSBP.
• Liver enzymes (AST, ALT) and 25-OH-Vitamin D levels showed significant predictive relationships with arterial stiffness parameters.

Conclusions:

• PWA provides valuable insights into vascular health in obese children.
• Arterial stiffness in obese children is associated with specific anthropometric and biochemical markers.
• PWA is a reliable tool for managing vascular health in the pediatric obesity population.
