摘要
目的分析理想体质量(IBW)、国外公式计算去脂体质量(JLBW、HLBW)替代中国肥胖患者去脂体质量(LBW)的可靠性,并建立中国肥胖患者LBW估算方程。方法选择269例肥胖患者,应用人体成分分析仪分析其LBW作为标准,分别与IBW及JLBW、HLBW进行比较,根据性别分为M组及F组,再根据体重指数(BMI)值的不同将每组分为3组,对各组及亚组进行统计学分析,并建立适合中国肥胖患者LBW的多元线性回归方程。结果 IBW与LBW比较,M组有统计学差异(P<0.05),F组无统计学差异(P=0.198)。JLBW、HLBW与LBW比较,M组和F组均有统计学差异(P<0.05)。随着BMI值的增加,差值均逐渐增加。中国肥胖患者LBW推算方程:LBW(女性)=16.4×身高(m)+0.42×TBW(kg)-9.525;LBW(男性)=23.762×身高(m)+0.529×TBW(kg)-21.867,方程统计学检验(ANOVA)具有统计学意义(P<0.01)。结论对于中国肥胖患者,无论是应用IBW还是国外LBW计算公式,可靠性均不理想,成功推算出中国肥胖患者的LBW的简易方程。
Objective To evaluate the reliability of using ideal body weight （IBW） and foreign formula rnethod （JLBW, HLBW） to replace the lean body weight （LBW）, and establish an equation to estimate LBW for Chinese obese patients. Methods Totally 269 cases of obesity patients were recruited for the study. The LBW analyzed by physical analyzer with biological resistance method was considered as a standard, and the LBW was compared with IBW, JLBW, and HLBW, respectively. The patients were divided into male （ M ） and female （F） groups, and then each group was further divided into three subgroups according to BMI. Statistical methods were used to analyze these groups and subgroups, and a multivariate linear regression equation was established which is appropriated for LBW analysis of obese patients in China. Results Significant difference was ob- served in group M comparing IBW with LBW （P 〈 0.05 ）, which was not found in group F （P = 0.198 ）. There were significant differencs on JLBW, HLBW and LBW between group F and group M （P 〈 0.05）. With the increase of BMI, difference also gradually increased. The equation which is ap- propriated for LBW of obese patients in China： LBW （ female ） = 16.4xheight （ m ） ＋ 0.42xTBW （ kg ） -9.525, LBW （ male ） = 23.762xheight （ m ） ＋ 0.529xTBW （kg）-21.867. The equation statistical test （ANOVA） is of statistical significance （P 〈 0.01 ）. Conclusion Neither IBW nor foreign formula method showed an ideal reliability to calculate the LBW for obese patients in China. An equation is established, which is appropriated for LBW of obese patients in China.
