布依族的人体组成成分分析

Analysis of body composition of Bouyei nationality

目的:研究布依族人体组成成分现状与特点。方法:随机抽取贵州黔西南布依族832例(男338例,女494例),采用生物电阻抗法进行人体组成成分测量。运用SPSS18.0统计软件对数据进行统计学处理。结果:布依族男性、女性全身脂肪分布特点均为躯干脂肪率、下肢脂肪率高于上肢脂肪率,男性身高、体质量、总肌肉量、推定骨量、总能量代谢、内脏脂肪等级、四肢肌肉量和躯干肌肉量均高于女性,四肢脂肪率、总体脂率及身体质量指数(BMI)女性则明显高于男性。随年龄增长,身高、体质量、四肢脂肪率和肌肉量、总肌肉量、骨量、总能量代谢呈下降趋势,内脏脂肪等级增加。结论:贵州黔西南布依族男性、女性总体脂率、BMI值均在国际规定肥胖判定标准的正常范围,与云南布朗族、河南回族、辽宁喀喇沁左翼蒙古族、昆明汉族相比偏低,与海南黎族相近。

Objective:To study the current status and characteristics of the body composition of the Bouyei people.Methods:A total of 832 healthy Bouyei people(338 males and 494 females)were randomly selected from the southwestern Guizhou province.Body composition of the participants were measured by bioelectrical impedance methods and statistical analysis was performed using SPSS 18.0 statistical software.Results:The body fat distribution of males and females of Bouyei nationality was characterized by higher trunk fat percentage and lower limb fat rate in comparison with upper limb fat percentage.The height,weight,total muscle mass,putative bone mass,total energy metabolism,visceral fat grade,limb muscle mass,muscle mass of the trunk of men were higher than those of women,while the fat percentage,total fat percentage and BMI were significantly higher in females than in males.Height,weight,limb fat percentage and muscle mass,total muscle mass,bone mass,total energy metabolism showed a downward trend and visceral fat grade increased along with the growth of age.Conclusion:The overall fat percentage and BMI of the Bouyei males and females in southwestern Guizhou are within the normal range of internationally defined obesity criteria.Compared with Yunnan Blang,Henan Hui,Liaoning Kalaqin Mongolian and Kunming Hanethnic groups,Bouyei nationality groups have lower overall fat percentage and BMI which is similar to Hainan Li group.
