[Ultrasound measurement of visceral fat in obese children]

Area of Science:

• Pediatric endocrinology
• Medical imaging
• Body composition analysis

Background:

• Anthropometric measurements are common clinical indicators of intraabdominal fat.
• Intraabdominal adipose tissue (IAAT) is a key factor in metabolic health.
• Accurate assessment of IAAT is crucial for pediatric obesity management.

Purpose of the Study:

• To investigate the correlation between ultrasound-assessed intraabdominal depth (IAAT) and anthropometric/biochemical parameters in obese children.
• To determine the utility of IAAT as a marker for body fat distribution in pediatric populations.

Main Methods:

• Cross-sectional study involving 69 obese children (38 boys, 31 girls).
• Measurements included anthropometry (height, weight, BMI, circumferences, skinfolds), blood pressure, and biochemical tests (glucose, lipids, insulin, C-peptide).
• Intraabdominal adipose tissue depth (IAAT) was measured using ultrasound; Pearson's partial correlations adjusted for age were calculated.

Main Results:

• In boys, IAAT showed significant correlations with BMI, chest and hip circumferences, waist/hip ratio, and multiple skinfold measurements.
• In boys, IAAT was also associated with serum triglyceride levels.
• In girls, IAAT correlated with BMI, chest and waist circumferences, and subscapular and abdominal skinfolds, but not with WHR or metabolic parameters.

Conclusions:

• Ultrasound-assessed IAAT is significantly associated with anthropometric indicators of body fat distribution in obese children.
• In obese boys, IAAT is additionally linked to elevated serum triglyceride levels.
• IAAT may serve as a valuable ultrasound-based index for assessing intraabdominal adiposity in pediatric obesity.
