甘南藏族人体组成成分分析

Analysis of human composition of the Gannan Tibetans

目的揭示甘南藏族人体组成成分特点。方法采用生物电阻抗法,测量了甘南藏族410例成人(男性221,女性189)人体组成成分。运用SPSS 20.0统计学软件对数据进行处理。结果相关分析结果显示,男性总肌肉量、推定骨量、躯干肌肉量随年龄增长而减小,水分率、内脏脂肪等级及躯干脂肪率随年龄增长而增大;女性身高及躯干肌肉量随年龄增长而减小,体重、总体脂率、身体质量指数(BMI)、内脏脂肪等级、右上肢脂肪率、右上肢肌肉量、左上肢脂肪率及左上肢肌肉量、右下肢脂肪率、左下肢脂肪率、左下肢肌肉量及躯干脂肪率随年龄增长而增大。单因素方差分析显示,男性水分率、内脏脂肪等级、躯干脂肪率及躯干肌肉量4项指标值年龄组间差异均具有统计学意义,其余14项指标值年龄组间差异均无统计学意义;女性体重、身高、总体脂率、总肌肉量、推定骨量、BMI、内脏脂肪等级、右上肢脂肪率、右上肢肌肉量、左上肢脂肪率、左上肢肌肉量、右下肢脂肪率、左下肢脂肪率、左下肢肌肉量、躯干脂肪率及躯干肌肉量16项指标值年龄组间差异具有统计学意义,其余2项指标值年龄组间差异均无统计学意义。u检验结果表明,男性体重、总肌肉量、推定骨量、水分率、四肢肌肉量及躯干肌肉量高于女性,女性总体脂率、四肢脂肪率、内脏脂肪率及躯干脂肪率高于男性。根据BMI判定,甘南藏族男性、女性超重;根据体脂肪率,甘南藏族男性属于非肥胖,女性属于肥胖。结论在13个族群中,甘南藏族男性、女性BMI、总体脂率较大。

Objective To reveal the characteristics of Tibetan human body composition in Gannan.Methods The body composition of 410 Tibetan adults(221 males and 189 females)in Gannan was measured by bioelectrical impedance method.The data were processed by SPSS 20.0 statistical software.Results Related analysis results showed that the total body muscle mass,estimated fat level and trunk muscle mass of the male decreased with age,while the percent body water,visceral fat level and percent trunk fat increased with age.The stature and left lower limb muscle mass of the female decreased with age,while body weight,percent body fat,body mass index,visceral fat level,percent right upper limb fat,right upper limb muscle mass,percent left upper limb,left upper limb muscle mass,percent right lower limb fat,percent left lower limb fat,left lower limb muscle mass and percent trunk fat increased with age.Analysis of single factor variance showed that there were statistically significant differences in the four indexes of male percent body water,visceral fat level,percent trunk fat and trunk muscle mass,while there were no statistically significant differences in the other 14 indexes among age groups.Females weight,stature,percent body fat,total body muscle mass,estimated fat level,body mass index,visceral fat level,percent right upper limb fat,right upper limb muscle mass,percent left upper limb fat,left upper limb muscle mass,percent right lower limb fat,percent left lower limb fat,left lower limb muscle mass,percent trunk fat,trunk muscle mass 16 index values were statistically significant differences between age groups,the remaining two index values were not statistically significant differences between age groups.The results of u test showed that the body weight,total body muscle mass,estimated fat level,percent body water,limb muscle mass and trunk muscle mass of males were higher than those of females,and percent body fat,limb fat rate,visceral fat rate and trunk fat rate of females were higher than those of males.According to the body mass index,Gannan Tibetan male and female were overweight;according to the percent body fat,Gannan Tibetan males were non-obesity and females were obesity.Conclusion The body mass index and overall fat content of Tibetan males and females in Gannan are relatively high among the 13 ethnic groups.
