【摘要】：目的测定北京市超重和肥胖成人基础代谢率(BMR),分析其与体成分的相关性,寻找适合我国超重肥胖人群基础代谢率的估算公式。方法采用间接测热法测定BMR,双能X线吸收法测定体成分,Pearson相关性分析检验BMR和体成分的关系,并将BMR实测值与常用公式估算值进行比较。结果 85名受试者基础代谢的能量消耗,超重组和肥胖组显著高于体重正常组(P0.001),肥胖组显著高于超重组(P=0.036)。超重组和肥胖组受试对象的基础代谢率与瘦体重相关性最强(r=0.865;r=0.784)。BMI正常和肥胖组受试者的脂肪组织质量与BMR无显著相关性,超重受试者的脂肪组织质量与BMR呈显著负相关(r=-0.484)。HENRY公式和LIU公式的BMR估算值与实测值差异2%,差异无统计学意义。结论超重肥胖人群的BMR要高于体重正常健康者。影响超重肥胖人群BMR的最主要因素是瘦体重,脂肪组织对BMR的影响尚不确定。HENRY公式和LIU公式适合我国超重肥胖人群。
[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，
