[Factors affecting oxidative damage in obese children: an exploratory study].

Area of Science:

• Pediatric Endocrinology
• Metabolic Disorders
• Oxidative Stress Research

Background:

• Obesity is a metabolic disorder associated with increased oxidative stress.
• Oxidative stress disrupts cellular redox balance, leading to physiological stress.

Purpose of the Study:

• To investigate the relationship between DNA damage and total antioxidant capacity (TAC) in severely obese children.
• To assess oxidative stress markers in pediatric severe obesity.

Main Methods:

• Analyzed blood samples from 11 severely obese children (mean age 9.5 years).
• Quantified DNA abasic sites (AS) and TAC levels using spectrophotometry and ELISA.
• Assessed metabolic syndrome risk factors.

Main Results:

• Identified elevated DNA abasic sites (4.1±4.0x105) and reduced TAC (0.218±0.03 mmol/L).
• Found a significant inverse correlation between AS and TAC (r = -0.63, p=0.038).
• Results indicate a redox imbalance in obese children.

Conclusions:

• Increased DNA damage and decreased TAC in severe obesity suggest a role for oxidative stress.
• Oxidative stress may be a key factor in the early development of obesity comorbidities.
• Early intervention targeting oxidative stress could mitigate long-term health risks.
