【摘要】：目的測定北京市超重和肥胖成人基礎(chǔ)代謝率(BMR),分析其與體成分的相關(guān)性,尋找適合我國超重肥胖人群基礎(chǔ)代謝率的估算公式。方法采用間接測熱法測定BMR,雙能X線吸收法測定體成分,Pearson相關(guān)性分析檢驗(yàn)BMR和體成分的關(guān)系,并將BMR實(shí)測值與常用公式估算值進(jìn)行比較。結(jié)果 85名受試者基礎(chǔ)代謝的能量消耗,超重組和肥胖組顯著高于體重正常組(P0.001),肥胖組顯著高于超重組(P=0.036)。超重組和肥胖組受試對(duì)象的基礎(chǔ)代謝率與瘦體重相關(guān)性最強(qiáng)(r=0.865;r=0.784)。BMI正常和肥胖組受試者的脂肪組織質(zhì)量與BMR無顯著相關(guān)性,超重受試者的脂肪組織質(zhì)量與BMR呈顯著負(fù)相關(guān)(r=-0.484)。HENRY公式和LIU公式的BMR估算值與實(shí)測值差異2%,差異無統(tǒng)計(jì)學(xué)意義。結(jié)論超重肥胖人群的BMR要高于體重正常健康者。影響超重肥胖人群BMR的最主要因素是瘦體重,脂肪組織對(duì)BMR的影響尚不確定。HENRY公式和LIU公式適合我國超重肥胖人群。
[Abstract]:Objective to determine the correlation between basic metabolic rate and body composition of overweight and obese adults in Beijing by (BMR), and to find a formula suitable for the estimation of basic metabolic rate of overweight and obese people in China. Methods BMR, dual energy X-ray absorption method was used to determine the body composition by indirect thermal method. The relationship between BMR and body composition was tested by Pearson correlation analysis, and the measured values of BMR were compared with those estimated by common formulas. Results the energy consumption of basic metabolism in 85 subjects in hyperrecombination and obesity group was significantly higher than that in normal weight group (P0.001), and that in obese group was significantly higher than that in hyperrecombination group (P 鈮，
