Intra-abdominal adipose tissue (IAAT) is associated with the metabolic complications of obesity. However the time course for the development of IAAT is not clearly defined because it is generally difficult to measure directly. The purposes of this short communication are to present data supporting the existence of IAAT in young children using direct measurement with computed tomography imaging, and to examine the relationship between IAAT and anthropometric indices in 16 healthy children (6.4 +/- 1.2 years; 24.8 +/- 5.4 kg).
Total body fat (6.4 +/- 3.5 kg) and fat free mass (18.4 +/- 3.6 kg) were determined by bioelectrical resistance. Fat distribution was estimated from eight individual skinfold measurements, the ratio of three trunk skinfolds to three extremity skinfolds (0.78 +/- 0.20), and the waist:hip ratio (0.90 +/- 0.08).
Mean abdominal subcutaneous adipose tissue (SCAT) was 65.3 +/- 44.8 cm2, and mean IAAT was 8.3 +/- 5.8 cm2. The ratio of IAAT to SCAT was 0.15 +/- 0.08, and the ratio of IAAT to total body fat was 1.44 +/- 0.84 cm2/kg. IAAT was significantly correlated with body weight (r = 0.54; P = 0.03), all skinfold measures (range r = 0.60-0.78; P = 0.02 to 0.0003) except at the calf, fat mass (r = 0.69; P = 0.003), and the trunk to extremity skinfold ratio (r = 0.78; P = 0.0003). There was no significant correlation between IAAT and the waist:hip ratio (r = 0.21).
These preliminary results establish the existence of IAAT in young children and suggest that individual trunk skinfold measurements and the trunk:extremity skinfold ratio provide a better indication of IAAT compared to the waist:hip ratio. However, as with adults, the relationship between intra-abdominal adipose tissue and anthropometry in children is complex.
腹腔内脂肪组织（IAAT）与肥胖的代谢并发症相关。然而，IAAT发育的时间进程尚未明确界定，因为通常难以直接测量。本简短通讯的目的是提供数据，支持使用计算机断层扫描成像直接测量来证明幼儿体内存在IAAT，并研究16名健康儿童（6.4±1.2岁；24.8±5.4千克）的IAAT与人体测量指标之间的关系。
通过生物电阻抗测定全身脂肪（6.4±3.5千克）和去脂体重（18.4±3.6千克）。根据八个体褶测量值、三个躯干体褶与三个肢体体褶的比值（0.78±0.20）以及腰臀比（0.90±0.08）估算脂肪分布。
平均腹部皮下脂肪组织（SCAT）为65.3±44.8平方厘米，平均IAAT为8.3±5.8平方厘米。IAAT与SCAT的比值为0.15±0.08，IAAT与全身脂肪的比值为1.44±0.84平方厘米/千克。IAAT与体重显著相关（r = 0.54；P = 0.03），与除小腿外的所有体褶测量值显著相关（范围r = 0.60 - 0.78；P = 0.02至0.0003），与脂肪量显著相关（r = 0.69；P = 0.003），与躯干至肢体体褶比值显著相关（r = 0.78；P = 0.0003）。IAAT与腰臀比之间无显著相关性（r = 0.21）。
这些初步结果证实了幼儿体内存在IAAT，并表明与腰臀比相比，个体躯干体褶测量值和躯干与肢体体褶比值能更好地反映IAAT。然而，与成年人一样，儿童腹腔内脂肪组织与人体测量学之间的关系很复杂。
