中文摘要 | 本研究的目的在評估目前用來估算基礎代謝率(Basal metabolic rate, BMR)的預測公式是否能準確地估算出健康中國成人之基礎代謝率。受試者共223人(男性102人,女性121人),年齡介於20-78歲(平均43.8±14.3歲)。每位受試者均接受間接熱量測定法(Indirect caloHmetry)測其BMR,並利用五個常用的預測公式(包括Harris and Beredict Equation,HBE)估算其BMR,同時比較測量值與估算值之差異。結果顯示,西方之預測公式均顯著高估健康國人之BMR達8-24,其中男性被高估8-21,女性被高估8-31。雖然由HBE所得健康國人之BMR與實際測量值有很高的相關性(男性,r=0.80,p=0.0001;女性,r=0.53, p=0.0001),但HBE的估算值仍然顯著高估實際測量值達14 ± 11,且女性被高估的程度較男性嚴重(男性,8 ± 8;女性,19 ± 11,p=0.0001)。以上結果顯示,目前用來估算BMR之預測公式均無法準確地估算出中國成人之基礎代謝率。 |
英文摘要 | The purpose of this study was to evaluate the validity of predictive equations for the calculation of basal metabolic rate (BMR) in healthy Chinese adults.Two hundred and twenty three healthy individuals (102 males and 121 femalesfrom 20 to 78 years old) were included in this study. The measured metabolicrate and predicted metabolic rate calculated from five equations including Harrisand Benedict Equation, HBE) commonly used to estimate metabolic rate werecompared. Our results showed that these equations overestimated BMR by 8 to24 for healthy Chinese. The measured values were overpredicted by 8 to 21for men and by 8 to 31 for women. Although there were significant correlations between measured and predicted BMR with using the HBE (men, r=0.80, p=0.0001; women, r=0.53, p=0.0001), the HBE overestimated BMR by 8 ± 8 for men and by 19 ± 11 for women if compared with measured BMR. Thesefindings suggested that the currently available predictive equations could not accurately estimate the BMR of healthy Chinese adults. |
