摘要

目的：本研究探討腳對腳模式生物阻抗分析與人體測量法之體脂率估測於台灣地區健康成年女性的精度差異。方法：以107名台灣健康女性（年齡：30.4±14.8歲、身高：160.6±6.0公分、體重：59.6±9.4公斤、身體質量指數（Body mass index，BMI）：23.2±3.8公斤／公尺^2，人體測量法應用Deurenberg等人發表的體脂率估測方程式、生物阻抗分析法使用商用腳對腳模式生物阻抗分析裝置（BIA4）估測所得的體脂率（BF%），分別與雙能X光吸收儀（DXA）的測量結果做比較，探討68名體重正常群組（BMI＜24公斤／公尺^2）、38名體重過重群組（BMI≥24公斤／公尺2）與全部受測者群組，分別進行相關係數、回歸分析、Bland-Altman分析與差值之均數檢定（t-test）。結果：人體測量法在體重正常、體重過重與全部受測者群組估測所得的BF%與DXA的相關係數分別為0.80、0.75與0.88，BIA4則為0.82、0.79與0.91，人體測量法與DXA的測量平均差值為-1.2%、95%信賴區間分別為-11.6%至9.2%，BIA_4則分別為1.5%、-6.7%至9.7%。人體測量與BIA4對於DXA測量所得BF%的差值，在全部受測者群組分別皆為顯著差異（P＜0.05）。結論：商用腳對腳模式生物阻抗分析裝置估測所得的體脂率相較於人體測量法，有著較高的相關係數與較小的信賴區間，表示商用腳對腳模式生物阻抗分析裝置相對於人體測量法，更合適於台灣健康成年女性的體脂肪測量。

Background &Purpose: The purpose of the study was to investigate the difference of the measuring accuracy between foot-to-foot bioelectrical impedance (BIA) analysis and anthropometric measurement estimating the body percentage in healthy Taiwanese female participants. Method: 107 healthy Taiwanese female (Age: 30.4±14.8, Height: 160.6±6.0cm, Weight: 59.6±9.4kg, Body mass index: 23.2±3.8kg/m^2). The study utilized the body fat percentage estimate equation developed by Deurenberget al. using the foot-to-foot commercial bioelectrical impedance analysis device for estimating body fat percent (BF%) and dual-energy X-ray absorptiometry (DXA) measured result to identify normal weight group (BMI＜24kg/m^2), over weight group (BMI ≥24kg/m^2), and all weight group by correlation coefficient analysis, regression analysis, Bland-Altman analysis and t-test. Results & Conclusions: Anthropometric measurement in normal weight, overweight, and all weight groups in BF% and DXA correlation coefficient were 0.80, 0.75, and 0.88. BIA was 0.82, 0.79, and 0.91. Mean difference between anthropometric measurement and DXA were -1.2%, 95% with confidence interval of -11.6% to 9.2%. BIA were 1.5%, -6.7% to 9.7%. When comparing the BF% mean difference between anthropometric and BIA measurements with DXA measurements, normal weight group and all weight group all showed a significant difference (P＜0.05). By utilizing the foot-to-foot mode BIA, the estimated BF% showed a better estimate when comparing the anthropometric measuring method in healthy Taiwanese female participants.
