Summary
Intra-abdominal adipose tissue (IAAT) exists in young children. Trunk skinfold measurements better indicate IAAT than waist-to-hip ratio in this age group.
Area of Science:
- Pediatric Endocrinology
- Body Composition Analysis
- Obesity Research
Background:
- Intra-abdominal adipose tissue (IAAT) is linked to metabolic issues in obesity.
- Direct measurement of IAAT is challenging, hindering understanding of its development over time.
Purpose of the Study:
- To confirm the presence of IAAT in young children using computed tomography (CT) imaging.
- To investigate the relationship between IAAT and anthropometric measurements in healthy children.
Main Methods:
- CT imaging was used for direct measurement of IAAT.
- Body composition was assessed using bioelectrical impedance.
- Fat distribution was evaluated using skinfold measurements and ratios (trunk:extremity, waist:hip).
Main Results:
- IAAT was directly measured in 16 healthy children (mean age 6.4 years).
- IAAT showed significant correlations with body weight, fat mass, and skinfold measurements.
- The trunk to extremity skinfold ratio was a better indicator of IAAT than the waist:hip ratio.
Conclusions:
- This study provides evidence for IAAT in young children.
- Trunk skinfold measurements are more indicative of IAAT in children than waist-to-hip ratio.
- The association between IAAT and anthropometry in children is complex, similar to adults.
