成年人體脂肪測量方法的比較及體位與體脂肪相關 性的探討

 本研究主要目的是要探討一般成年人與肥胖者，以分段多頻率生物電阻分析 法所得之體脂率為標準值，比較足到足生物電阻分析法、手到手生物電阻分 析法及紅外線測量法其所得之體脂率的相關性及準確性；並探討肥胖者體脂 肪及身體組成與一般體位者的差異性。本研究分為二部分，研究一以一般成 年人為對象，男性 25 人，女性 93 人，結果顯示：四種測量法均具有相關性

，但以足到足及手到手生物電阻分析法所得之體脂率無統計性的差異，而紅 外線測量法所得之值明顯的偏低（ P < 0.05 ）；體位測量的腰圍、臀圍、腰 臀比、身體質量指數均與體脂率成正相關性，其中男性以腰圍（ r=0.72, P < 0 .0001 ）女性以 BMI （ r=0.79, P < 0.0001 ）呈最顯著正相關性。研究二以肥 胖者 BMI > 27 kg/m2 為對象，男性 6 人，女性 21 人，結果顯示：以足到足及 手到手生物電阻分析法所得之體脂率並無統計性的差異，紅外線測量法明顯 的偏低（ P < 0.05 ），其中肥胖男性以手到手電阻法

（ r=0.93, P < 0.05 ），肥胖女性以足到足生物電阻法所得之值更接近標準值

（ r=0.80, P < 0.0001 ）；體位測量方面肥胖男性只有臀圍與體脂率有正相關

（ r=0.85, P < 0.05 ），肥胖女性以腰圍、臀圍、 BMI 與體脂率有正相關性，

以 BMI （ r=0.78, P < 0.001 ）呈最顯著正相關性。探討腰臀比值則所有肥胖 男女兩性的腰臀比與體脂率並無相關性，而且不能夠代表減重的成果。

Comparison with the methods for measuring body fat and interrelations hips between anthropometry and body fat in adults



The purpose of this study is to compare the methods among Segmental Bioelectrical Impedanc

e Analysis (SBIA), Foot-to-Foot Bioelectrical Impedance Analysis (FFA), Hand-to-Hand Bioe

lectrical Impedance Analysis (HHA), and Near Infra-red Interactance (NIRI) for measuring th

e accuracy of body fat and finding the correlations of body composition for normal adults and

obese adults. The variations of body fat and body composition for obese and normal adults are

also investigated. This study is divided as two phases. In phase 1, 25 men and 93 women are st

udied. The results show that all four methods are correlated. However, no significant statistic d

ifferences presented in measurement of body fat percentile using both FFA and HHA and low

er measurement (P < 0.05) observed for NIRI. Body fat percentileile is correlated with body w

aist circumference (WC), hip circumference (HC), waist to hip ratio (WHR), and body mass in

dex (BMI). The significant correlated values are presented for men with WC (r=0.72, P < 0.00

01) and women with BMI (r=0.79, P < 0.0001). In phase 2, the obese adults, 6 men and 21 wo

men with BMI over 27 kg/m2 are investigated. The results demonstrate that no statistic differe

nces presented in measurement of body fat percentile using both FFA and HHA, however, the

lower measurement (P < 0.05) presented for NIRI. It also shows that the standard values are ac

hieved using HHA for obese men (r=0.93, P < 0.05) and using FFA for obese women (r=0.80,

P < 0.0001). Body fat percentile is only correlated with HC for obese men (r=0.85, P < 0.05),

while it is correlated with WC, HC and BMI for obese women, the significant correlated value

s with BMI (r=0.78, P < 0.001). It also shows that body fat percentile is not correlated with W

HR for both obese men and obese women. However, it can not show the index of weight contr

ol result.
