本研究评估了超声测量皮下脂肪准确确定 18-29 岁年轻人全身和局部身体脂肪的能力。通过超声波测量 135 名受试者（83 名男性，52 名女性）五个身体部位的皮下脂肪组织 (SAT) 厚度，并与双能 X 射线吸收测定法 (DXA) 测量的相应节段脂肪量进行比较。 SAT 厚度的超声测量与节段脂肪量和体脂总百分比 (%) 密切相关 (r - 0.697-0.907，p < 0.01)。使用分位数回归生成的预测方程发现，腹部和大腿处的 SAT 厚度可以准确预测男性的体脂百分比（估计标准误差，SEE = 1.9%，95% 一致性限 (LoA)；-3.6% 至 +3.8%），腹部和小腿内侧的 SAT 厚度可以准确预测女性的体脂百分比（SEE = 3.0%，LoA；-6.5% 至 +5.4%）。这些数据表明，SAT 厚度的超声测量按比例反映了节段脂肪量，并准确预测了年轻人的体脂百分比。 （电子邮件：siobhan.leahy@ul.ie） (C) 2012 年世界超声医学与生物学联合会。
This study evaluated the ability of ultrasound measurement of subcutaneous adiposity to accurately determine whole body and segmental body fat in young adults aged 18-29 years. Subcutaneous adipose tissue (SAT) thickness was measured by ultrasound at five body sites in 135 subjects (83 men, 52 women) and compared with the corresponding segmental fat mass measured by dual energy X-ray absorptiometry (DXA). Ultrasound measures of SAT thickness were strongly correlated to segmental fat mass and total percentage (%) body fat (r - 0.697-0.907, p < 0.01). Prediction equations generated using quantile regression found SAT thickness at the abdomen and thigh to accurately predict % body fat in men (standard error of the estimate, SEE = 1.9%, 95% limits of agreement (LoA); -3.6% to +3.8%) and SAT thickness at the abdomen and medial calf to accurately predict % body fat in women (SEE = 3.0%, LoA; -6.5% to +5.4%). These data indicate that ultrasound measurement of SAT thickness proportionally reflects segmental fat mass and accurately predicts % body fat in young adults.
