中文摘要 | 本研究使用生物電阻分析法(BIA),測量台灣青少女(n=94)年齡從17-27歲之體脂肪含量。測量值再與現有由身高、體重、年齡、性格及體格指數(BMI)所估算預測脂肪含量之三(Womesley公式,Ganow公式和Black公式)相比較,結果顯示這些估算體脂肪含量公式的預測值與生物電阻分析法之實際測量值,有明顯的誤差高達5-55。雖然由Black公式所估算之體脂肪含量與實際測量值有很高的相關達(r=0,874 p<0.0001),但仍有明顯的誤估5±18,顯示這些由體格指數所推得之體脂肪含量估算公式,均無法準確地預測台灣青少女之體脂肪含量,而本研究目的,則使用統計線性迴歸方法,對BIA法估計之體脂肪含量值與體格指數尋求一較適合台灣青少女體脂肪含量估算公式之建議修正為BF=1.657BMI-11.209,其誤差為2±18。另外由台灣青少女之身高與體重所算得之體格指數平均值為21.0±2.9kg/m2而與實際測量之體脂肪平均數為23.5±5.5相比較,雖然其體格指數落於正常範圍值(20-25Kg/m��),但體脂肪含量卻有高於正常值(14-18)的現象,顯示其台灣少女仍有普遍肥胖傾向。 |
英文摘要 | This research used bioelectricial-impedance analysis (BIA) to measure Taiwan young females' (average age 19.5 ± 2.1) body fatness. By comparing three body fatness measurement equations (Womesley equation, Garrow equation and Black equation) using height, weight, age, sex and BMI as variables, the reasult indicated singnificant error from 5 to 55 in three equations. Although using Black equation produced high correlation with actual measurment (r=0.874, p <0.0001), it showed significant error of 5 ± 18. As a result, these three body fatness measurement equations can not properly caculate Taiwan young females'body fatness. Thus, the purpose of this study was to develop a suitable equation to develop a suitable equation to estimate Taiwan young females' body fatness. Bt using Regression Analysis comparing actual measurement and bodymass index, this adapted formala is : BF = 1.657 BMI -11.309 (error=2 ± 18). Except above finding, the authors find that Taiwan young females' bodymass index average is 21.0 ± 2.8 kg/m�� and body fatness average is 23.5 ± 5.5.From this finding, Taiwan young females' body mass index is fall within normal range (20-25 kg/m��). However, their body fatness is higher than normal range14-18) which shows fat tendency of Taiwan young females. |
