【摘要】：目的比较生物电阻抗法(BIA)和双能X线吸收法(DEXA)检测体脂成分的相关性,评估BIA法用于日常体脂成分监测的可靠性。方法 2014年1月至2014年12月招募志愿者145例,同时采用DEXA和BIA法检测体脂含量。采用Pearson相关分析进行两组数据的相关性检测,Bland-Altman法分析BIA法与DEXA法测量结果的一致性。结果在男、女性受试者中,BIA法检测的全身体脂比例与DEXA法测得的数据显著相关(P0.0001)。相对单频BIA法,双频BIA法测得的体脂比例与DEXA方法检测结果的相关系数更高(r=0.92,95%CI 0.89~0.94,P0.0001)。Bland-Altman图形分析法表明BIA与DEXA法测量结果基本一致。结论 BIA法作为一种简单、便捷、无放射性的体脂检测方法,可用于日常体脂成分的检测和随访,其改进的双频BIA法更接近DEXA检测的体脂含量。
[Abstract]:Objective to compare the bioelectrical impedance analysis (BIA) and dual energy X-ray absorptiometry (DEXA) to investigate the relationship between body fat and BIA method for reliability evaluation of daily monitoring of body fat. Methods from January 2014 to December 2014 to recruit volunteers in 145 cases, while using DEXA and BIA method to detect the body fat content. The correlation detection of two groups of data using Pearson correlation analysis, consistency measurement and analysis of BIA method and DEXA method results in Bland-Altman method. Results in the male and female subjects, were significantly related to body fat percentage and DEXA BIA method for detecting the measured data (P0.0001). The single frequency BIA method, the correlation coefficient of the detection results of body fat with the proportion of DEXA measured by the method of dual frequency BIA higher (r=0.92,95%CI 0.89~0.94, P0.0001).Bland-Altman graphical analysis showed that BIA and DEXA measurement results are basically consistent. Conclusion BIA method is a simple, convenient, no body fat radioactive detection The method can be used for the detection and follow-up of daily body fat components. The improved double frequency BIA method is closer to the body fat content of DEXA.
