Obesity is an abnormal accumulation of body fat directly proportional to reduced life expectancy. Treatment of this ailment should be preceded by proper and accurate assessment of the degree of obesity.
The main objective is the justification of anthropometric empirical indicator (AEI) by the utilization of chest and pelvic radiographs, so that precise measurement of obesity on economical grounds can be manifested. Also, the subsequent objective is to establish a comparative scenario between dual energy X-ray absorptiometry (DXA) and novel, portable, bioelectric impedance analysis (BIA)-based body composition analyzer, MI-105 (Meditech International Inc. India).
The cross-sectional design was adopted in the present study, in which 20 female participants from urban south India were involved. The measurements of body composition, anthropometry and chest (covering the region from neck to abdomen) as well as hip radiography of the studied population were acquired.
The higher significant difference of ≤0.001 was evidenced in all female studied population in the main body composition parameters measured by DXA and low-cost BIA. The same framework of significance is applicable to AEI, AEI (image morphed) and AEI (image automatic).
The novel-derived parameters: AEI (image morphed) and AEI (image automatic) can precisely gauge obesity and can be the effective alternatives for high-cost DXA. In addition, low-cost BIA-based body composition analyzer can also be the better substitute for DXA.
肥胖是身体脂肪的异常堆积，与预期寿命缩短成正比。在治疗这种疾病之前，应该对肥胖程度进行适当而准确的评估。
主要目的是通过利用胸部和骨盆X光片来证明人体测量经验指标（AEI）的合理性，以便能够从经济角度精确测量肥胖程度。其次，目的是建立双能X线吸收法（DXA）与新型便携式生物电阻抗分析（BIA）身体成分分析仪MI-105（印度Meditech International Inc.公司）之间的比较情况。
本研究采用横断面设计，纳入了20名来自印度南部城市的女性参与者。对研究人群进行了身体成分、人体测量以及胸部（覆盖从颈部到腹部的区域）和髋部X光摄影测量。
在通过DXA和低成本BIA测量的所有女性研究人群的主要身体成分参数中，均显示出≤0.001的高度显著差异。相同的显著性框架适用于AEI、AEI（图像变形）和AEI（图像自动）。
新得出的参数：AEI（图像变形）和AEI（图像自动）能够精确测量肥胖程度，可成为高成本DXA的有效替代方法。此外，基于低成本BIA的身体成分分析仪也可以是DXA的更好替代品。
