确定连接安卓平板电脑的手持式超声（US）与参考方法双能X线吸收法（DXA）在测量肥胖程度方面的一致性程度。
对104名成年人（63名女性，41名男性）进行了全身DXA扫描以及使用手持式超声测量腹部脂肪组织厚度。从DXA获得体脂百分比（BF%）、总脂肪量（kg）和躯干脂肪量（kg）。从超声获得皮下脂肪组织（SAT）、浅部皮下脂肪组织（SSAT）和深部皮下脂肪组织（DSAT）厚度。将超声得出的按性别区分的总脂肪量、躯干脂肪量和BF%估计值与DXA进行比较。采用斯皮尔曼相关性分析和布兰德 - 奥特曼图来评估两种方法之间的一致性。
超声SAT与女性（rs = 0.74）和男性（rs = 0.87）的总脂肪量都有很强的相关性，与躯干脂肪量也有很强相关性（女性，rs = 0.81；男性，rs = 0.83）；SSAT和DSAT也是如此（女性：rs = 0.65和rs = 0.66；男性：rs = 0.63和rs = 0.85，所有p值均<0.0001）。布兰德 - 奥特曼图显示男性和女性的总脂肪量和躯干脂肪量都有很强的一致性。对于BF%，男性观察到可接受的一致性界限，但女性没有，使用SAT测量BF%时发现有显著的比例偏差，表现为负斜率（r = -0.298，p = 0.0177）。
手持式超声以及分析腹部脂肪组织厚度的技术与DXA结果有很强的一致性，并且对两性的总脂肪量和躯干脂肪量得出了高度可比的估计值。
To determine the extent of agreement between a handheld ultrasound (US) attached to an android tablet and the reference method dual energy x-ray absorptiometry (DXA) for the measurement of adiposity. A whole-body DXA scan and abdominal adipose tissue thickness measurements using a handheld US were obtained from 104 adults (63 females, 41 males). Body fat percent (BF%), total fat mass (kg), and trunk fat mass (kg) were obtained from DXA. Subcutaneous adipose tissue (SAT), superficial subcutaneous adipose tissue (SSAT), and deep subcutaneous adipose tissue (DSAT) thickness were obtained from US. Sex-specific total fat mass, trunk fat mass, and BF% estimates by US were compared with DXA. Spearman’s correlations and Bland-Altman plots were used to assess agreement between the methods. US SAT correlated strongly with total fat mass for both females (rs = 0.74 ) and males (rs = 0.87) as did trunk fat mass (females, rs = 0.81; males, rs = 0.83); as did SSAT and DSAT (females: rs = 0.65 and rs = 0.66; males: rs = 0.63 and rs = 0.85, respectively, all p-values < 0.0001). Bland-Altman plots demonstrated strong agreement for total and trunk fat mass for both males and females. For BF%, acceptable limits of agreement were observed for males but not for females, substantial proportional bias as indicated by a negative slope was noted for BF% using SAT (r = −0.298, p=0.0177). The handheld US and technique to analyze abdominal adipose tissue thickness showed strong agreement with DXA results and generated highly comparable estimates for total and trunk fat mass for both sexes.
