Obesity and its diagnostic methods in Turkish children

Area of Science:

• Pediatric Endocrinology
• Nutritional Science
• Biomedical Engineering

Background:

• The reliability of Body Mass Index (BMI) for obesity classification in diverse populations is increasingly debated.
• Bioelectrical impedance analysis (BIA) has emerged as a potentially accurate method for obesity screening.
• Accurate obesity assessment is crucial for early intervention and management in children.

Purpose of the Study:

• To evaluate the accuracy of Bioelectrical impedance analysis (BIA) against Body Mass Index (BMI), skinfold thickness (SFT), and leptin levels for obesity classification in children.
• To determine the correlations between BIA measurements and other obesity indicators.

Main Methods:

• A case-control study involving 178 children (90 obese, 88 control).
• Measurements included BMI, SFT, leptin levels, and BIA-mediated body fat percentage (BIA BFP).

Main Results:

• Obese children exhibited significantly higher BMI, leptin levels, SFT, and BIA BFP compared to controls (p<0.001).
• BIA BFP showed strong correlations with BMI, SFT, and waist circumference.
• A weak to moderate correlation was observed between BIA BFP and leptin levels.

Conclusions:

• Bioelectrical impedance analysis (BIA) is a validated and accurate method for assessing body fat percentage in pediatric obesity.
• BIA can enhance obesity diagnosis accuracy, potentially avoiding misclassification issues associated with BMI, especially in adolescent males.
