基于人体成分分析的中国成人静息能量消耗及预测公式的研究

Study on resting energy consumption and prediction formula of Chinese adults based on body composition analysis

目的研究我国不同性别、年龄、BMI人群的体脂百分比(PBF)、内脏脂肪面积(VFA)及静息能量消耗(REE)等,研究9种REE预测公式的准确度。方法纳入2016年4月至2019年9月在该院体检的成人共3098例。基于生物电阻抗分析法的人体成分分析仪器获得REE测量值、PBF、去脂体重(FFM)、VFA等,统计分析采用配对t检验、pearson相关性分析、线性回归、吻合度、Bland-Altman一致性分析法。结果31~40岁中国成人的REE最高,随着年龄的增高,逐渐降低;BMI值与REE呈正相关;女性的PBF和VFA超标严重;9种REE预测公式均高估了成人的基础代谢水平,Owen公式相对中国成人较合适,若BMI在正常范围则选用Yang公式更好;研究提出了自己的REE公式,即女性:272.586+6.844H+6.908W,男性:-683.523+9.444H+8.491W,其中H表示身高(单位:cm),W表示体重(单位:kg)。结论我国成人的REE最好选择REE测量设备,在没有测量设备的情况下可选择Owen公式和Yang公式,18岁以上的成人也可选择该研究提出的REE公式。

Objective To study the percentage of body fat(PBF),visceral fat area(VFA)and resting energy expenditure(REE)of the population in China with different sex,age and BMI index,and to study the accuracy of nine kinds of REE prediction formulas.Methods A total of 3098 adults were included in the physical examination in this hospital from April 2016 to September 2019.REE,PBF,fat free mass(FFM),VFA,etc.were obtained by the body composition analysis instrument base on the bioelectrical impedance analysis method.Paired t-test,pearson correlation analysis,linear regression,coincidence degree and Bland-Altman consistency analysis were used for statistical analysis.Results At the age of 31 to 40 years old,the REE of Chinese adults was the highest,which decreased gradually with the increase of age;There was a positive correlation between BMI and REE;The PBF and VFA of women were severely exceeding the standard;nine kinds of REE prediction formulas all overestimated the basic metabolic level of adults.Owen formula was more suitable for Chinese adults,if BMI was in the normal range,it was better to choose Yang formula.This study put forward its own formula of REE,that was,female:272.586+6.844H+6.908W,male:-683.523+9.444H+8.491W["H"represented height(cm),"W"represented weight(kg)].Conclusion It is best to choose REE measuring equipment for REE of adults in our country.In the absence of the measuring equipment,it is best to choose Owen formula and Yang formula to predict the REE of Chinese adults.Adults over 18 years old can also choose the REE formula proposed in this project.
